From the Reisbeck supplement
Part 23 of the Federal Aviation Regulations require only the all engines operating distance over a 50-ft. height be presented for take-off distance. Along with the FAA-approved optional performance in this subsection, we include for your information Accelerate-Go, Accelerate-Stop, Climb Limited Weight, Net Climb Gradient, and other information generally tailored to FAR Part 25. For data not shown in this section, refer to Section V of the Beechcraft POH.
ALTERNATE RAISBECK BALANCED FIELD LENGTHS
There is increasing world-wide acceptance of FAR Part 25 safety standards in the smaller turboprop and turbojet
Corporate and Airline fleet. Raisbeck Engineering offers its fully Raisbeck-Equipped 200/B200 aircraft with equivalent FAR Part 25 Balanced Field Lengths, tailored to FAA Advisory Circular, AC25-7.
Take-off field length requirements for flaps UP and APPROACH may be drawn from this subsection as an alternate to the standard enhanced Raisbeck take-off performance detailed in the previous subsection.
Some of the more important FAR Part 25 requirements utilized to calculate performance in this subsection are as follows:
● Decision speed (V1) is faster than engine failure speed (VEF) by the demonstrated pilot engine-failure recognition time, plus one-second.
● If continuing take-off:
-rotation speed (VR) must be faster than 1.05 VMCG
-Speed at 35 feet altitude (V2) must be faster than 1.2 Vs
-Speed at 50 feet altitude (V50) is considerably faster than 1.2 Vs
● If aborting take-off
-brake application may not begin until V1, (see decision speed, above)
-Throttle-Chop may not begin until demonstrated pilot brake application time plus one second.
-No propeller reverse of any type may be utilized to contribute to the stopping distance.
FAR 25 charts included in manual. Can post copies if anyone requires, ask for which one.
