Performance - Takeoff: Final 4040 Flashcards
The length of runway which is declared available by the appropriate authority and suitable for the ground run of an airplane taking off.
Take Off Run Available (TORA)
The distance required to accelerate an aircraft on all engines, lose an engine and then either take off or abort in the same distance
Critical Field Length
This is the length of the TORA plus the length of the clearway. The clearway length cannot exceed 1/2 the TORA.
Take Off Distance Available (TODA)
This is the length of the takeoff run available plus the length of any stopway.
Accelerate Stop Distance Available (ASDA)
The presence of runways contaminants means that the maximum takeoff weight for an aircraft will _____________.
increase
decrease
not change
change depending upon what is causing the limitation
decrease
What is the overriding assumption that you must make when calculating takeoff data for a multiengine aircraft?
That you can stop the aircraft on the remaining runway after reaching Refusal Speed.
That you can land back on the runway if you loose an engine prior to 35 feet AGL.
That you can avoid all obstacles with all of your engines running
That you are going to loose your critical engine at the worst possible time.
That you are going to loose your critical engine at the worst possible time.
The maximum speed at which the crew can decide to abort the takeoff. It is the lowest of VREF and VR.
Decision Speed (V1)
The speed at which the pilot initiates the rotation, at the appropriate rate of about 3° per second
Rotation Speed (VR)
The maximum ground speed that can be reached, in order to limit the centrifugal forces and the heat elevation that may damage the tire structure.
Maximum Tire Speed (VTIRE)
The speed which you can accelerate on all engines, loose an engine and either abort or take off in the same amount of runway.
Correct match:
Critical Engine Failure Speed (VCEF)
This speed corresponds to the energy absorption capability of the brakes.
Maximum Brake Energy Speed (VMBE or VBMAX)
It is the minimum climb speed that must be reached at a height of 35 feet above the runway surface, in case of an engine failure. It may not be less than 1.2 VS for turbo-jet powered airplanes and 1.10 times VMCA
Take Off Climb Speed (V2)
The speed that you can accelerate to on all engines, lose an engine, and stop in the remaining runway.
Refusal Speed (VREF)
An increase in outside air temperature means the maximum takeoff weight for an aircraft will __________________.

When you compute take off run available, do you just use the runway length?
Yes
No, you have to subtract the runway the aircraft uses to line up
No, you have to subtract 250 feet from the runway length
Yes, if you are doing a full power take off. If you are doing a reduced power take off, you must reduce to runway available by 1000 feet.
No, you have to subtract the runway the aircraft uses to line up
