The purpose of the study is for the FAA to recommend RSA Improvements that could, in their judgement be accomplished to improve safety of aircraft operations at the airports. At Key West International, the RSA improvements, if any, would be included in the proposed runway resurfacing project. EVALUATION: The completed forms in Appendix I of Order 5200.8 Runway Safety Area Program show that the Florida Keys Marathon Airport (MTH) presently meets the RSA requirements while the Key West International Airport (EYW) does not. Therefore the study will concentrate solely on the latter airport's needs. (see Exhibits A & B) The existing critical aircraft at (EYW) is the ATR-72 Flown by American Eagle which requires an Airport Category of Bill; however, the airport is shown as a C category on the Jeppesen approach charts, In addition, Comair has proposed to start service to the airport in the near future with the Canadair Regional Jet. This model of aircraft requires the airport be designated OIL The Bill category requires a RSA of 300' wide and 600' long while the 011 category requires a RSA of 500'x1000, Therefore, both existing and proposed RSA's are discussed in the study, Due to the length of time required to get a determination from the permitting agencies, not only are both RSA's addressed, but also possible short term and long term solutions in an attempt to improve existing conditions, The following determinations specified in the Order 5200-8 will be evaluated and recommended, as applicable: 1, The existing RSA meets the current standards contained in AC 150/5300-13, 2, The existing RSA does not meet standards but it is practicable to improve the RSA so that it will meet current standards. 1 N :IURS\deidresIC503743.IIIO 1 0226toc.wpd 3. The existing RSA can be improved to enhance safety, but the RSA will still not meet current standards, 4. The existing RSA does not meet current standards, and it is not practicable to improve the RSA, CONSIDERATIONS IN EVALUATING ALTERNATIVES INCLUDE: a.) A research of incidents/accidents involving aircraft utilizing the RSA provides the following: 1, 1995 - Cape Air Cessna 402 - Baggage door opened - .:t 300' off east end of runway little damage - no injury, 2. 1989 - EAL - B-727 - Short landing to Runway 9 Approach - slight damage - no injury, 3. 1982 - Private - Cessna Skymaster - engine problem - stopped .:t 600' off east end of runway - gear damage - no injury. 4, 1979 - Air Florida - B-737 - ran off west end - slight damage - no injury. b.) This is a one-runway airport with a non-precision approach to Runway 9, The existing design aircraft is the ATR-72 and future design aircraft (scheduled for April 2001) is the Canadair, Current passenger enplaned are 298,124 and operations 126,959. Year 2010 forecasts are 429,558 for enplaned passengers and 158,825 operations both of which exceed the capacity of the terminal facilities, All weather use of the runway is .:t 95% and IFR :t 5%, Runway 9 utilization is :t 95% and Runway 27 :t 5%, c.) The RSA compliance is shown on the included exhibits, The west end has a RSA of 110' in length while the east end varies from 210' to 400', (see Figures 1 & 2) d.) The RSA on the west end is primarily a salt pond approximately 2' to 4' in depth, The RSA on the east end is mangroves, wetlands and associated endangered species which may utilize such habitats. (see Figures 3 & 4) e,) The climate conditions are very favorable with low visibility limited both in occurrences and length of time. IFR weather is typical to a tropical climate, f.) Both Runway 9 and 27 have a VASI installation with REILS and a non-precision VOR straight in approach to Runway 9, (see Exhibits G & H) 2 N :\URS\deidresICS03743.11 \01 0226toc.wpd ALTERNATIVES CONSIDERED: a.) Relocation, shifting or realignment of the runway is not a realistic alternative due to lack of land available and the environmentally sensitive adjacent property. b.) Existing runway length is minimal for the present aircraft operations and therefore could not realistically be reduced in length, c,) A combination of (a) and (b) above is not realistic due to the above mentioned conditions. d.) Declared distances calculations have been considered (see Exhibits D & E). The results of these calculations have been coordinated with Comair, American Eagle and Continental Express Airlines. The results range from ceasing operations to off- loading passengers, neither of which are acceptable to the airline or airport management e.) Engineered Materials Arresting Systems (EMAS) has been investigated and is further discussed in the conclusion section of this report, (see Exhibit F), EVALUATION OF ANTICIPATED ENVIRONMENTAL IMPACTS In order to evaluate the requirements of FAA Order 5200.8/ Runway Safety Area Program at Key West International Airport (KWIA), URS Corporation has evaluated proposed runway safety areas (RSA) to document existing environmental conditions and anticipated impacts from the proposed project Two alternative RSAs have been evaluated, The first proposed RSA would extend 600' from the end of the runway and 150' north and south of the centerline of the runway at both the east and west end of the runway; total area approximately 8.2 acres in size. The second proposed RSA would extend 1,000' from the end of the runway and 250' north and south of the centerline of the runway at both the east and west end of the runway; total area approximately 23 acres in size, The existing natural communities were mapped on color aerial photographs (1 "=300') of the study area. Copies of these aerials are provided in Figures 3 and 4, Each habitat was then classified using the Florida Land Use, Cover and Forms Classification System (FLUCFCS/FDOT 1999) and the U,S, Fish and Wildlife Service (USFWS) Classification of Wetlands and Deepwater Habitats of the United States (Cowardin, et al., 1979). N:\URS\deidres\C503743.11 \KWIAl RSAdoc 3 East RSA Three (3) land uses and vegetative communities would be impacted by the East End RSA including airport (811), exposed rock with marsh grasses (731), and mangrove swamp (612), (Table 1 and Figure 3). The airport consists of the approximately 25' wide cleared and disturbed area adjacent to the perimeter of the runway and all of the airport facilities, The exposed rock with marsh grasses is the transition zone between the airport and the mangrove wetlands. While surface water may not be present for much of the year, water levels are near the ground surface and ground cover is dominated by hydrophytic herbaceous vegetation including seashore saltgrass (Distich/is spicta), saltwort (Batis maritima), sea oxeye (Borrichia arborescens and B. frutescens), sea purslane (Sesuvium portu/acastrum), and glasswort (Sa/cornia bige/ovil). The mangrove swamps comprise most of the East RSA and extend well beyond the RSA to the east The mangroves are dominated by red mangrove (Rhizophora mangle) which grow in shallow tidal waters with stands of black mangrove (Avicennia germinans) and white mangrove (Laguncu/aria racemosa) at higher elevations. Various species of nuisance/exotic vegetation also appear in the RSA including Brazilian pepper (Schinus terebinthefo/ius) and Australian pine (Casuarina equisetifolia). In addition, the larger RSA would extend outside the current airport property and would require land acquisition, Table 1 - East RSA Land Uses and Vegetative Communities 612 Estuarine, 3.1 Intertidal, Forested, Broad- leaved Ever reen 731 Exposed E2EM1 Estuarine, 0,8 0.9 Rock with Intertidal, Marsh Emergent, Grasses Persistent 811 Airport 0,2 0.7 Total 4,1 11,5 N:\URS\deidres\C503743.11 \KWIAI RSAdoc 4 West RSA Six (6) land uses and vegetative communities would be impacted by the West End RSA including exposed rock with marsh grasses (731), bays and estuaries (Salt Ponds) (540), mangrove swamp (612), Brazilian pepper/Australian pine (422/437), road and highway (814), and open land (190), (Table 2 and Figure 4). The exposed rock with marsh grasses is the transition zone between the airport and the mangrove wetlands, While surface water may not be present for much of the year, water levels are near the ground surface and ground cover is dominated by hydrophytic herbaceous vegetation including seashore saltgrass (Distichlis spicta), saltwort (Batis maritima), sea oxeye (Borrichia arborescens and B, frutescens), sea purslane (Sesuvium portu/acastrum), and glasswort (Sa/cornia bige/ovil). The lakes present in the West RSA are Salt Ponds consisting of open water. No bathymetric data is available, but depths appear to vary from less than l' to approximately 4'under high tide or extreme rainfall events. The Salt Ponds are connected to other Salt Ponds via culverts and ditches, Mangrove swamps surround the Salt Ponds and are dominated by black mangrove (Avicennia germinans) with stands of white mangrove (Laguncu/aria racemosa) at higher elevations, Various species of nuisance/exotic vegetation also appear in the RSA including Brazilian pepper (Schinus terebinthefo/ius) and Australian pine (Casuarina equisetifo/ia), An airport access road traverses the West RSA; it is approximately 20' wide and connects to Government Road, West of the access road is a large area of inactive cleared open land, Table 2 - West RSA land Uses and Vegetative Communities 540 Bays and E10W Estuarine, 1.8 2,8 Estuaries Subtidal, Open Water 612 Mangrove E2F03 Estuarine, 1.5 3.4 Swamp Intertidal, Forested, Broad- leaved Ever reen 731 Exposed E2EM1 Estuarine, 0.6 0.9 Rock with Intertidal, Marsh Emergent, Grasses Persistent 190 Open Land 0,1 2,0 N:\URS\deidres\CS03743.11 \KWIAl RSAdoc 5 422/437 Brazilian - - - 2,2 Pepper/Austr alian Pine 814 Roads and - - 0,1 0.2 Highwavs Total 4,1 11,5 ENVIRONMENTAL PERMITTING AND MITIGATION Several agencies regulate wetlands within the project area. These agencies include the U,S, Army Corps of Engineers (USACOE), the Florida Department of Environmental Protection (FDEP), and the South Florida Water Management District (SFWMD). Other agencies, including the U.S. Fish and Wildlife Service (USFWS), the U,S, Environmental Protection Agency (USEPA), the National Marine Fisheries Service (NMFS), the Florida Fish and Wildlife Conservation Commission (FFWCC), and the Florida Department of Community Affairs (DCA) review and comment on wetland permitting. It is currently anticipated that the following environmental permits would be required for this project: Permit Environmental Resource Permit (ERP) Section 404 Dredge and Fill Permit Local Construction Permit Issuina Aaencv SFWMD USACOE DCA The complexity of the permitting process will depend greatly on the degree of the impact to jurisdictional wetland areas, Based on the assumed impacts identified above, it is anticipated the USACOE will require an Individual Permit. An Individual Permit will involve compliance with the 404(b)(1) guidelines, including verification that all impacts have first been avoided to the greatest extent possible, then unavoidable impacts have been minimized to the greatest extent possible, and finally that unavoidable impacts have been mitigated in the form of wetlands creation, restoration, and/or enhancement. SFWMD has indicated by letter dated January 10, 2001 (see Attached), that it will be involved in the permitting process. SFWMD will require an Environmental Resource Permit (ERP) because the proposed project will result in impacts to Waters of the State. Based on the anticipated impacts identified above, it is expected that an Individual Permit would be required with mitigation for wetland impacts, These specific issues would be determined during the permitting process, In accordance with Chapter 62-302,700 F ,A. C, (see Attached), the waters of Key West are a designated Outstanding Florida Waters and Outstanding National Resource Waters as N:\URS\deidres\CS03743.11 \KWIAI RSAdoc 6 a result of being located in the Key West Wildlife Refuge, Florida Keys National Marine Sanctuary, and designated Special Waters. As a result these areas are afforded the highest protection in regards to degradation of water quality, It also appears that the Salt Ponds located at the KWIA receive the same protection, placing greater permitting restrictions on them. As of February 28, 2001 the United States Army Corps of Engineers (USACOE) has not responded to our request made last year for input to the study Mitigation for USACOE is anticipated to be at a 1:1 ratio (acres created: acres impacted) for open water and 2: 1 for wetland impacts or the equivalent of the impacted wetland's Functional Unit Values. This would require creating approximately three acres of open water and 30 acres of wetlands for the 1000' x 500' RSAs, Mitigation for SFWMD is anticipated to be higher than for the USACOE; in the range of 40 to 90 acres of wetland creation. Long-term monitoring, maintenance of mitigation areas in perpetuity, and the placement of conservation easements over mitigation areas are expected requirements of both the USACOE and SFWMD. ANTICIPATED MITIGATION COSTS Costs associated with the projected mitigation are difficult to determine at this time, It would include engineering and permitting costs, project construction and possibly land acquisition. Using the Florida Department of Transportation's cost of $ 75,000 per acre for Florida Department of Environmental Permitting mitigation costs (land, design, construction costs) the RSA's projected cost might be 3 - 6,75 million dollars. Considerable additional effort would have to be expanded to arrive at a more accurate figure; and this could only be accomplished once the permitting process has been initiated and mitigation requirements established by the permitting agencies, CONCLUSION OF ENVIRONMENTAL EVALUATION In view of the proposed use of regional jets at KWIA, the preferred alternative of a 1000' x 500' RSA was evaluated, Based on this environmental evaluation construction of the East and West RSAs - which would involve filling, leveling, and compacting of the ground - would result in approximately 18 acres of impact to jurisdictional wetland areas (11 acres at the East End RSA and 7 acres at the West End RSA), Jurisdictional limits of wetlands have not been verified by permitting agencies and are only estimated for the purposes of this study. In addition to the above mentioned mitigation scenarios, it appears the East 1000' x 500' RSA would extend outside the current airport property. This would have to be defined more clearly through field surveys; then, either more land would have to be acquired or the RSA size reduced. The West RSA would require fill of the salt ponds and adjacent mangrove habitat, an issue that would raise serious concerns with the permitting agencies and the environmental community as a whole, N :\URS\deidres\C503 743.11 \KWIA1 RSAdoc 7 FINDINGS: Based on the foregoing data as a result of investigations, consideration and information provided in Order 5200-8 Runway Safety Area Program, the following findings appear to be appropriate: 1. Pursue environmental/wetlands mitigation to provide RSA of 116' width and 200' from end of the runway on the east end using an engineered materials arresting system (EMAS) starting 50' from the runway end. (See Exhibit F from Engineered Arresting System Corp.). Total cost is estimated at $ 2 million. If the RSA was extended to 400' (350' EMAS) estimated total mitigation and construction total cost is $ 4 million and to 460' (410' EMAS) total estimated mitigation and construction cost is $ 5 million. 2. Based on the primary landing and take-off from Runway 9 approximately 95% of the time and the highly sensitive concerns involving the adjacent salt pond, it appears nothing could reasonably be done on the west end RSA. 3. Mitigation of the entire RSA (500'x1000') on the east end would require mitigation of:t 70 acres at a cost estimated up to $ 10 million. 4. A partial increase in the east end RSA by matching the area north of the runway centerline (210') with the south area (400') for a complete 400' length and 300' to 500' width RSA. The 300' wide RSA is estimated at a total cost of $ 1,000,000, the 500' wide RSA is estimated at $ 1,500,000 total cost. 5. To accomplish the task in either 3 or 4 above may require 3-5 years for the permitting, mitigation and construction of the RSA. Therefore it appears nothing significant could be accomplished before initiating the Canadair operations. However, the past record of incidents/accidents does not seem to indicate an urgency or reason to prevent aircraft operations at this time. If the operations are approved by the airlines FAA Principal Operating Inspector. It is understood that after review of this study the Federal Aviation Administration will determine the requirements for the Runway Safety Areas Improvement if any, at Key West International Airport prior to approving the runway resurfacing project.

The appropriate State agency responsible for the review of an Environmental Resource Permit (ERP) application would be the South Florida Water Management District. An application to conduct the proposed activity would be reviewed as an Individual ERP. This application package would require documentation indicating how avoidance and minimization of wetland impacts was addressed as well as a secondary and cumulative impacts analysis. Once minimization and avoidance of wetland impacts is adequately addressed and secondary and cumulative impacts identified, a mitigation plan can then be reviewed. Please be aware that the proposed mitigation ratios contained within your correspondence (1 :1 for open water, 2:1 for mangrove impacts) are significantly lower than required by the Basis of Review. Mitigation ratios will be determined during the permitting process onoe the impact area has been thoroughly reviewed and the type of mitigation proposed is identified, but should be in accordance with guidelines set forth in the Districfs Basis of Review. A determination as to the permittability of the proposed project will require further information regarding the quality of the proposed impact area. This additional information should include, but would not be limited to providing information related to listed species utilization of the area and water quality benefits derived from the wetland community.

However, since that submittal, we have been requested by the FAA to enlarge the RSA from the 300' x 600' size we submitted to 500' wide by 1000' long, This would be needed to meet the safety requirements of a different aircraft mix than currently serving the airport. This is also expected to increase wetland impacts from the previous estimate of 8 acres to around 10-12 acres, As a reminder, we are requesting the District's opinion whether the project is permittable, what type of mitigation may be required by the District and what type of permit application should be submitted. Please respond ASAP since we are now beyond our original deadline for completing the study. Thank you for your cooperation.

Box 75021 Cincinnati/Northern Kentucky International Airport Cincinnati, Ohio 45275 Reference: Balanced Field Runway Requirements for Regional Jet Service at Key West International Airport Dear Mr. Helm: As a follow-on action to our telephone discussions earlier today, we hereby request your assistance in determining the potential of Comair Airline's use of 50-70 passenger Regional Jets at Key West International Airport (EYW). This request in very similar to previous questions posed by Mr. Mil Reisert of our firm in October of 1999 regarding the potential for reduced payload operations by your existing turboprop fleet when declared distance criteria is applied at EYW. We have recently developed new declared distance data for Runway 9/27 using revised assessments of existing Runway Safety Area (RSA) deficiencies beyond each end of the runway. As you know, the land areas beyond each end of the runway are not of sufficient size to accommodate the development of the required FAA 300-foot wide by 600-foot long RSA. As such, the landing thresholds for Runways 9 and 27 should be displaced inward 490 feet and 390 respectively. The resulting declared distances would be as follows: Runway 9 Runway 27 TORA 4,800' TORA 4,800' TODA 4,800' TODA 4,800' ASDA 4,410' ASDA 4,310' LDA 3,920' LDA 3,920' We request your assistance in verifying that Com air Airlines operations using 50- to 70- seat Regional Jets may be severely restricted or precluded with limited payload and/or operational range to and from EYW when applying declared distance criteria. Also, we would like to know if there is any payload limits without the declared distance criteria. Please contact me with any questions and/or comments at (813) 286-1711.

'This will significantly reduce the maximum allowable landing weight As a result of this reduction, 10 to 11 pa$$cmgers will be inconvenienced. Based on this analysis, Comair strongly opposes finy reduction in length of the Key West runway. The reduction would force us to reduce the number ofpasst.-ngers attempting to use the Key West uirport for departure by 3 to 5 passengers, Arrival:; would be reduced by JO to II pasllengeI"li.

Note the required Takeoff distance at 16.600 is 4500. To takeofJat with 4100 feet would reduce our load canying capacity by 1,000 pounds (5 passengers and their bags). This is the second major issue to e1fect our service into Key West International Airport The first issue is the Joss of Category C for the NDB. We are now forced to use tadar vectors to the 071 bearing of the Fish Hook NDS to let down visually. We do DOl have an approved instrument approach until the Category C for the NOB is re-established. Key Wesl International is IeSbicted to VFR use. We call upon your authority and in1luence to correct these issues.

The Key West Airport is certified for A, B and C approach categories. The 50 seat CRJI 00/200 is certified for approach category D. This precludes the CRJlOOI200 from operating into the Key West Airport at this time. If a furture change occurs which would allow us to operate the CRJlOOI2oo into Key West, we would still be severely restricted on payload with the current runway configuration. Pending certification for the 70 seat CRJ700 is targeted for approach category C. This will allow us to operate into Key West. Comair will primarily operate this aircraft from Key West to our Southern Hub in Orlando, Preliminary analysis of the CRJ700 indicates this aircraft will be able to carry 70 passengers to Orlando under normal conditions, If the proposed declared distance is implemented at Key West, we would not be able to operate the CRJ700 into the Key West Airport. Comair intends to operate an all jet fleet by December 200 I. Based on this analysis, if the Key West (EYW) Airport is required to implement the proposed declared distance, Comair would no longer be able to serve the Key West Airport, For this reason, Comair strongly opposes any reduction in length of the Key West runway. Even with the currentIength, we face many operational concerns with the introduction of Jet service to the Key West Airport Please contact me with any questions and/or comments at (859) 767-2398 Sincerely, ~1JL Brandon Helm Flight Operations Performance Analyst P.O. Box 75021 . CINCINNATI, OHIO 45275 . 606-767-2550 February 20, 2001 Dear Mil, Following is a summary of the preliminary performance modeling results for runway 9-27 at Key West. Note these are truly preliminary, as bed sizes are based on limited data for some of these aircraft. RSA length needed to get 70 knots for air carrier aircraft is estimated at 460 feet. This includes 50 feet between the runway end and the beginning of the arrestor bed. For the existing 210 foot RSA space an arrestor bed 150 feet long by 116' wide could be installed after grading (raising grade to get out of the tidal area, establishing a centerline crown and 1 to 1.5% side slope) and paving from the runway end to 210 feet. Following is the estimate maximum runway exit speed performance based on ESCO's computer simulation: * 53 knots for a 50 seat CRJ(at 47,000 lbs., similar weight to ATR-72 and ATR-42, Dash-8 in use at Key West) * 48 knots for a Gulfstream business jet (at 75,000 lbs., similar to max t-o weight for the heavier CRJ-70) * 46 knots for a Saab 340 (at 22,500 lbs. similar weight to EMB-120 in use at Key West) * 43 knots for Beech All stated performance is based on no reverse thrust and a braking friction coefficient on the pavement between the runway end and the arrestor bed of 0.25. With reverse thrust and typical wet pavement friction available, performance would be even better, exceeding 50 knots for all the above. Cost for the 150' by 116' arrestor (based on a 100' wide runway) would be approximately $70 per square foot, or $1,220,000 plus site prep costs. This figure includes production, shipping, installation and finishing of the arrestor bed. Site prep would consist of * the grading and paving discussed above * moving any junction boxes outside the bed foot print * modifying any lights in the bed to have two frangible points, one at the base surface and one at the arrestor bed surface * constructing a concrete beam across the front of the arrestor bed on which a debris deflector (supplied by ESCO) would be mounted * 3" drop off from concrete beam to level of paving immediately behind it, where first row of blocks is placed. This reduces the "step" going into the arrestor bed to provide a smooth transition for an overrunning aircraft. I hope the above information is helpful.

PURPOSE. This :id...i:;ory cil'cultlr (AC) t;omains standards for th~ planning, dc:>ign, and installation of Engineered MSlena13 Arrestmg Systems (EMAS) in runway safety areas. Engineered MateriaJs means high energy absorbing materiah of :sclected stn;ngth, whicb will reliably and predictably c1'U5h under the weight of an airer;lft, 2. BACKGROUND. Aircraft can and do overrun the ends of runways, sometimes with disastrou8 r=ult:;. An overrun occurs when an llircrllft pas"cs beyond the eno of a runway during :in aborted takeoff or while bndillg. The majority of such overruns by air carrier aiccr:ltt come to rest within 1000 fect of the runway cnd and between the extended edges of thc ruoway. Data on aircraft overruns Ovcr a 12-ycar period from 1975 to 1987 indicate that a large llUljQrity of all overruns (appl'Ol<imatc:ly 90%) oecur at cx:it spccw of 70 knotS Or ICIl5 (ReferenCE: 7, Appendix 2). In order to minimize the hazards of overruns, the Federal Aviation Atlministration (FAA) incocporated into airport design ,;t:md:mis the conoept of :l :!:lfety area beYlmtl the runway end.

Wh"TC:: natuml obstacles (bollies of water or sharp drop-ofTs), local development (roads and raikoads), or environmental constraints (wetland encroachment), make thc COMlcuction of II standard snf~ty area impracticable. Thac have been accidents at Some: of these airports wbcn~ the ability to stop an overrunning aircraft within the ruow;ay snfc:ty are;a would have prevented major dam3El" Co :\ireraft and injurie9 to p3sseng~r;j. Date: 8/21/98 initiated by: AAS-IOO Recognizing the: diffiCUIric:i associated with achieving 11 ~tandard safety area at QU airports, the: FAA umkrtook research programs on the use of VariULL~ materials for arresting systems and, in conjunction with industry, conducted a series of field tests utilizing an insuumemed Boeing 727 aircraft. A$ a result of the data obtained from these tcst programs, the Port AUlhority of New York and New Jersey (PANYINJ), in [997, installed an EMAS sompri:iCd of cellular cement on (he Runway 4R safety area lit John f. Kennedy [ntemacional Airport. Thill prototype system is bClng monitored to provide infonnation on system longevity. 3. APPLICATION. At some alrport.~. reconstruction of a runway requires its safety 3rC;llS to be brought up to current standards to the extent practicable. Of course, confonnance with current SlD.nd4rd3 i~ <ksicnbJc at all airport.~, even when not requin:d by regulation. OccnsionaUy, however, it may not be practicable to achieve a standard safety area as ;;pecificd m Table::; 3-1, 3-2. and 3-3 or AC 150/5300-13, tUrpon Desfgn, In these situations. Appendix 14, Df!clared Disrances. of that AC provides an alternative means of enhancing safety. The declared distaoct; illte:mative allows an airpoG owner to ucclm-e what portiolU of an operatIonal runway arc available to :5ati~f)r the aircraft's acceleratc-stop and landing distance rc:quiremems. wllh runway beyond these "dcclarc:d distances" available liS runway safcty ilrcu. However, the use: of declared distances at some airports may result in the inlJbility to aCCommodate;: aircraft that are currently in use at that airport. In such a ::ituation, in;;talling an EMAS may be another way of ellhancinz; safcty. An EMAS is NOT II substi[Ute for, nor equivalcnt co, any kngth or width of runway safery arca and does not affect declared distance: calculations An EMAS is also not intcnded to meet the: ddiniclOn of a stop way as provided in AC 150/5300-13. --...--..,;.4;. -JVI 01 -L,.iU UL..L.

One may elect 10 follow an alternate method. provided it is also found by the Federal Avjntion Administration (FAA) to bc an acceptable means of complying with Title 14, Code of Federal Regulations (CFR). Chapter I, FAA. Therefore. mandatory ttllTUi such as .shall" or "must" used herein apply oaly to those who seek to demonstrate compliance by use of the specific method described by lhis AC, or for those for whom the WIC of these guidelines is mandatory. such as tbose installing an EMAS funded under Federal grant assistance progr.l.ms. 4. RF.T.ATEO READING MATERIAL. Appendix 2 contains a listing of docwnents with supplemental material relating to EMAS. These um;umcnts comain cenain information on materials evaluated. as well as design. construction. and testing procedures utilized to date, Testing and data previously generated under FAA studies referenced in Appendix 2 may be used as input to an E1vlAS design withaur further justification. 5. PLANNING CHARTS. Thc purpose of Figures AI-l through AI-4 is to allow a preliminary analysis. providing sufficient information to determine whether to proceed with a detailed engineering design of an uptimum EMAS installation. They are intended (Q be used as a preliminary screening tool only. They 3IT nor sufficient for final design, which mu~t be customized for each in.~tallation. The charts illll~trate estimated EMAS stopping distance capabilitie~ for various aircraft types. The design used in each chart is optimized ~pccifically for the aircraft noted un tht: chart anti assumes the availability of brakes and reverse thrust. It should be noted that the absence of either would result in longer stopping distances. 3.. Example 1. Assumc a candidate runway ha~ a runway safety area that extends 500 feet beyond the end or [he n.lnway and the design aircraft is Q DC-9 (or similar).

For purposes of cksign. the EMAS can be considered fixed by it~ function and frangible since it is designed to fail at a specified impact load.. Therefore, an EMAS is not con~idcred an obstruction under 14 CFR Part 77 Objects Affecring Navigable Airspace. The followin~ system design requirements shall prevail for all EMAS installations. a. Concept. All EMAS is designed (0 stop an overrunning aircraft by exerting predictable deceleration forces on its landing gear as the EMAS material crusb~s. It must be designed to minimize the pOlcntil:l1 for structural damage to aircraft, since such damage could result in injuries to passengers and/or affect the predictability of deceleration forces. b. Location. An EMAS is localed beyond tbe end of the runway, centered on the e~tended runway centerline. It will usually begin at some distance from the end of the runway to avoid damage due to jel blast and short landi.ngs (Figure I). This distance will vary tlcpending on the available area and the EMAS materials. c, Desi.gn Method. An EMAS design Shllll be supported by a validated da<;ign method, which can predict the performance of the system. The design aircraft is deftned liS that aircraft using the llll50eiated runway that imposes the greatest demanu upon the EMAS. To the extent practicable, however, the EMAS design should cOllSider the range of aircraft expected to operate on the runway. In some instances, this may be preferable to optimizing the EMAS for the design aircraft The design method shall be derived from field or laboratory tests. Testing may be based on passage of either an actual aircraft or equivalent single wheel load through a test bed. The design must consider multiple aircraft paramet~, including but not necessarily limited to allowable aircraft gear load.~. gear configuration, tire conbiet pressure, aircraft center of gravity. and aircraft speed. The model m~t calculate imposed aircraft gear loads. g-forces on aircraft OCcuplUlts, deceleration rBles, limI stopping dislances wilhin the arresting system. Any rebound of the crushed material that may serve 10 Iessell its effectiveness must be con$idcrcd. d. Operation. The EMAS shall be a passive system.

The EMAS shall be desLBnc:d and conslnlctcd so mat it will not be damaged by expected jet blast. n. RepaJr. The EMAS must be designed to be repaired to a usable coodition within 45 days uf ~c by tbe design aircraft at the design entrance speed. It sbould be Doted that this is a dCsllZI\ requirement only- not an operntional requirement. 7. MATERIAL QUALIFICATION.
