Takeoff Data Flashcards
Best Climb Speed
the greater of the speed for MAX ROC or the flaps up air minimum control speed.
Flaps Up Safety Speed (FUSS)
The minimum speed recommended for normal operation with the flaps retracted. FUSS is the greater of 1.25 times the flaps up power off stall speed or the flaps up air minimum control speed.
Operation at FUSS provides __ g of maneuvering capability with all engines operating or __ g of maneuvering capability with one engine inoperative.

Defining conditions for Vmca
- ATCS operational
- Bank angle equal or less than 5 degrees away from failed engine
- Max takeoff power on all engines
- Max rudder deflection limited by 150 lbs rudder force or max rudder control surface deflection
- Minimum flying weight
- No. 1 engine failed, prop auto fx’d
- Zero rudder trim
Defining conditions for Vmca2
- Bank angle equal or less than 5 degrees away from failed engine
- Flaps 50%
- Max takeoff power on all engines
- Max rudder deflection limited by 150 lbs rudder force or max rudder control surface deflection
- Min flying weight
- No. 1 & 2 engined failed. No. 2 auto-fx’d and no. 1 prop either windmilling or feathered
- Rudder trim required for a 3 degree approach with 3 engines
- Gear down
Refusal speed
Max speed to which the aircraft can accelerate to with engines at takeoff
The crosswind limited takeoff run must be initiated with a maximum indicated power level of 2500 HP until 35 kts is reached. At 35 kts the power levers are advanced to full takeoff power. This procedure results in a __ ft penalty to all takeoff distance requirements.
200
Critical Field Length
total runway distance required to accelerate on all engines to Vcef, experience an engine failure, then continue the takeoff or stop within the same distance.
Refusal Speed
the maximum speed to which the aircraft can accelerate with engines at takeoff power and then stop within the remainder of the runway available, with two engines in reverse, one engine in ground idle, one prop fx’d, and max anti-skid braking.
Define Critical Failure Speed
speed to which the aircraft can accelerate, lose an engine, and then either continue the takeoff with the remaining engines or stop in the same total runway distance.
