Day 8 - TOLD Flashcards
Define Takeoff Rated Thrust (TRT)
Maximum allowable thrust limited by 104% N1, 700C ITT, or 2900 lbs of thrust whichever occurs first and limited to 5 minutes max
Define Maximum Continuous Thrust (MCT)
Maximum allowable thrust that may be used without a time limitation and is limited by 104% N1, 680C ITT, or 2900 lbs of thrust, whichever occurs first
How often must MCT be recomputed
Every 5000 feet
Define Maximum Cruise Thrust (MCRT)
The highest thrust setting that is recommended for use in cruise
Define Go-around %N1
The maximum allowable thrust for use during a go-around limited by 104%N1, 700C ITT, or 2900 lbs of thrust, whichever occurs first
Define Critical Engine Failure Speed (Vcef)
The speed at which one engine can fail and the same distance is required to either continue to accelerate to lift-off speed, or to abort and decelerate to a full stop
Define Critical Field Length (CFL)
The total length of runway required to accelerate on all engines to critical engine failure speed, experience an engine failure, then continue to lift-off or stop. (must be no greater than the runwayavailable)
Define Minimum Control Speed Ground (Vmcg)
The minimum controllable speed (88 KIAS) during the take-off run at which, when an engine is failed, it is possible to maintain directional control using only primary aerodynamic controls without deviating more than 25 feet laterally with all 3 wheels on the runway.
What assumptions are considered for Vmcg
It assumes the remaining engine at TRT, the aircraft loaded at the most unfavorable weight and CG, aircraft trimmed for takeoff, and without exceeding 180 lbs of rudder control force with rudder boost operating. (crosswinds and RCR may increase VMCG)
Define Minimum Control Speed Air (Vmca)
The minimum controllable speed (89 KIAS) in the take-off configuration out of ground effect with one engine inoperative and the remaining engine at TRT
Vmca is determined at __
The most critical combination of asymmetric thrust, light weight, and aft CG
What assumptions are considered for Vmca
Aircraft trimmed for takeoff, 5 degrees angle of bank into the operating engine and no more than 180 lbs of rudder control force with the rudder boost operating
Define Refusal Speed (Vr)
The maximum speed that can be attained, with normal acceleration, from which a stop may be completed within the available runway length
Define Maximum Braking Speed (Vb)
The maximum speed from which the aircraft can be brought to a stop without exceeding the maximum brake energy limit of 14.8 million foot-pounds
When is an acceleration check required
Whenever S1 is less than Vrot
