TOLD Flashcards
Def: Takeoff Distance
Distance, in feet, from brake release to main gear liftoff
Def: Refusal Speed (BEO)
Maximum speed to which the aircraft is able to accelerate with both engines operating in MAX and abort with both engines operating
Def: Refusal Speed (EF)
Maximum speed to which the aircraft is able to accelerate with both engines operating in MAX and abort with an engine failure
Def: Single Engine Takeoff Speed (SETOS)
The speed at which the aircraft is able to climb, once clear of ground effect, at a minimum of 100 feet per minute with gear down, flaps 60%
Def: Decision Speed
The minimum speed at which the aircraft is able to experience an instantaneous engine failure and still accelerate to SETOS and takeoff in the remaining runway
Def: Critical Field Length
The total runway length required to accelerate with both engines operating to the CEFS, experience an engine failure, then either continue to accelerate to SETOS and takeoff, or stop in the same distance
Def: Critical Engine Failure Speed
The speed to which the aircraft accelerates with both engines, experience an engine failure, and permit either acceleration to SETOS and takeoff, or decelerate to a stop in the same distance
Def: Minimum Acceleration Check Speed
The minimum acceptable speed at the check distance with which takeoff should be continued
Refusal Speed Assumptions
1) 3-Second Delay
2) Under BEO, both engines producing MAX thrust. In EF, one engine is producing MAX thrust while the other is windmilling
3) Throttles are pushed to idle and aircraft decelerates. Cautious braking from 130-100 so desired braking is achieved in 2 seconds.
4) If aborted during rotation, aerobrake is held until 120 KCAS
5) Under BEO, both engines are producing idle thrust. Under EF, one is producing idle thrust and the other is windmilling
Decision Speed Assumptions
1) 3-second delay to recognize and react
2) At the end of 3-second reaction time, the aircraft maintains or returns to 3-point attitude and accelerated to SETOS with neutral stick
