Call, ]idaho 83638 Honorable Clyde Archer Mayor, City of McCall McCall, ID 83638 7720 June 28, ].984 Dear Hayor Archer: The Payette National Forest is currently planning to construct a facility for Smokejumper and Retardent operations on a site ad- joining the McCall City Airport. The site is located on the west side of the airport on lands that we a~:e currently ih the proc:ess acquiring ownership through a land exchange with the State of Idaho. 'Fo facilitate access to the airport runway, we construct a parallel taxiway from the site ~o the north end of RunWay 161 The enclosed plat illustrateg the proposed locati~in ' ~i~-~'[~-~'-'9'hnway to facilitate exit upon landing and access to the east side taxiway for departures on Runway As you know, the Federal Aviation Administration had defined specific separation standards in regards to the relationship of parallel ta×iways to airport runways. These separation standa~ds ar~, found in FAA Advisory CJ. rcu].at*s AC 150/5300 and AC 150/6300 (o~7 which applicable portions are also enclosed). Our proposal is to construct a 50 foot wide parallel, taxiwdy with the centerline 306 feet from the runway centerline and 94 feet f~'om the west property line of the abondoned railroad right-of-way which is owned by the. State of Idaho. The 306 foot separation meets the F~i separation standards for all aircraft that we anticipate using in our oper.'itions exc~q)t for t:he DC-6. The DC-6 wing tip would penetrate the safety zone 2 feet, 9 ~nches. In discussing this with Michael. R. t;rader, F~ Airport Planner, by our Engineering Staff, Mr Crader indicated that would be preferable to permit a variance for the DC-6 aircraft rather than reduce the 94 foot separation from the property line. 2 We are seeking approw~] of tt~is proposal at ~:be earliest possible date. If you have further questions, pleas~, contact Gene Benedict in the Supervisor's Office. Sincerely, /K~i~NETH D. WL~YERS Forest Supervisor EIIC1 osures cc: Benedict ]"bi S~aff bi.

For Airplane Design Group V, the standard minimum run~ay centerline to taxiw~y centerline sep~rution distance is 400 feet (120 m) for airports at or below an elevation of 1,345 feet (410 m); 450 ft~et (135 m) for airports between elevations of 1,345 feet (410 m) and 6,560 feet (2 000 m); ~d 5PO fee~ (150 m) for airports above an elevation of 6,560 feet (2 000 m). _5/ Buildings and parked aircraft may penetrate the ai.rport imaginary surfaces defined in Subpart C of FAR Part 77 where an FAA aeronautical study has determined that the s~cific ~enetration will. pot result in a hazard to air navigation. The runway centerline to property/building line separation distance may be reduced to 50~'feet (150 dependent on a FAA no hazard to air navigation determination. Chap 2 Par 13 11 2128/83 AC 150/5300-12 CHAPTER 3. RUNWAY DESIGN 14. INTRODUCTION. This chapter provides the standards for such elements as runways, shoulders, the runway safety area, blast pads, c~learways, and stopways. Also included are recommendations on firefighting and rescue access roads. Table 3-1 p~esents the minimum widths and lengths for runway elements. Table 3-1.

For airplanes in Design Group III with a maximum certificated takeoff weight greater ~]an 150,000 pounds (68 000 kg), the standard runway width is 150 feet (45 m) and the runway blast pad width may be increased to 190 feet (57 m). 4_/ For airplanes in Aircraft Approach Category C, the safety area w~dth increases 20 feet (6 m) for each additional 1,000 feet (300 m) of airport elevation greater than 8,200 (2 500 m) above sea level. For airplanes in Aircraft Approach Category D, the safety area width increases 20 feet (6 m) for each 1,000 feet (300 m) of airport elevation above sea level. 5_/ For a runway with a stopway over 1,000 feet (300 m) in length, the runway safety area extends to the end of the stopway. Chap 3 Par 14 15 9/23/83 me Chap 1 Par 3 AC 150/5300-4B CH{; 7 Obstacle. An obstacle is any fixed or mobile object which is located on an area intended for the surface movement of aircraft, which extends above a defined surface intended to protect aircraft in flight, which interferes with the siting or operation of navigational aids~ or which ;~y affect the establishment of instrument procedures; Obstacle Free Zone (OFZ). An OFZ is an area: (1) Comprised of the runway OFZ, the approach OFZ, and the inner- transitional surface (a) Runway OFZ. The runway OFZ is the volume of space above a surface longitudinally centered on the runway. The elevation of any point on the surface is the same as the elevation of the nearest point on the runway centerline. The runway OFZ extends 200 feet (60 m) beyond each end of the runway and its width is: i 120 feet (36 m) for visual runways serving o£ ex[~cted to serve only small airplanes with approach ~xeeds less than 50 knots. 2 250 feet (75 m) for nonprecision instrument and visual runways serving or expected to serve ~nall airplanes with approach speeds of 50 knots or more and no large airplanes. 3 300 feet (90 m) for precision instrument runways serving or expected to serve only small airplanes. (Gee figure 1-1.) 4 180 feet (54 m), plus the wingspan of the most demand[n9 airplane~ plus 20 feet (6 m) per 1,000 feet (300 m) of airport elevation; or, 400 feet (120 m), whichever is .greater, for runways .serving or expected to serve large airplanes. (See figure 1-1.) (2) (3) (c) Inner-Transitional Surface OFZ. The inner-transitional surface OFZ is t3~e volume of space above the surfaces which slope 3 (hori- zontal) to 1 (vertical) laterally from the edges of the runway OFZ and approach OFZ and end at the height of 150 feet (45 m) above tihe established airport elevation. The inner-transitional surface applies only to precision instrument runways. (See figure 1-1.) Free of all objects, except frangible air navigational aids (NAVAIDs).
