Dash 1 - TOLD Flashcards
Accel check time
The time req to accelerate to a predetermined speed
Ground Min Control Sped (Vmcg)
The minimum speed at which the A/Cs engine most critical to aircraft directional control can fail, while remaining engines operate at the selected thrust and stil mainatin directional control. No more than 28 feet from the originally intended ground path can result while using elevators, airlerons, spoilers, rudder, and NWS on a dry hard runway with a one second pilot reaction time
Engine failure recognition speed (V1)
The speed is reached 1.5 seconds after the most critical engine faiure which gives the same distance to either continue takeoff or stop
Critical field length
Total runway length required to accelerate with all engines to critical engine failure speed, experience a most critical engine failure, then continue to takeoff or stop
Refusal Speed (VR)
The max speed t which the aircraft can accelerate and then stop in the available runway
Max brake energy speed (VBMAX)
The highest speed from which the aircraft may be brought to a stop without exceed the max design energy absorbtion capability of the brakes
Rotation Speed (VROT)
The speed at which rotation from the 3 point attitude to the takeoff attitud is initiated
Go Speed(VGO)
The speed at which the pilot normally becomes committed to continue the takeoff. Determined prior to brake release. Go speed is lowest of VROT, VR, or VBMAX. If VGO is VR, then VR must be greater than or equal to VMCG. IF VGO is VBMAX, then VBMAX must be greater than or equal to VMCG and V1. If VGO is VROT, and increase in VROT due to wind gust increases VGO an equal amount, not to exceed VR or VBMAX.
Takeoff Speed
The speed at which the main gear leaves the ground
Takeoff ground run
The ground distance traveled to takeoff speed
Air minimum contro speed
The min airspeed at which a straight line flight path can be maintained with the engine most critical to lateral or directional control failed and with the remaining engines operating at MAX thrust. A stright line flight path must be maintained with max rudder deflection and no more than 5 degrees of bank away from the dead engine
Minimum Climbout Speed
The min speed recommended for three-engine obstacle clearance
Climb gradient
The instantaneous capability for height increse divided by the distance traveled. Usually a percentage. Also defined by units of feet per nautical mile where one percent climb gradient is approx 60 feet per nautical mile
Climb out factor
Used to assess the climb gradient and obstacle clearance capability.Represents the climb gradient capability in percent, available with flaps and slats set for takeoff at a height of 50 feet, with gear retatcted, out of ground effect at the min climbout speed. For these conditions, the climbout factor is equal to the climb gradient capability.
Min Flap Retraction Sped (VMFR)
The min speed at which the flaps can be raised
