Performance Flashcards
What defines a balanced field ?
It’s where the accelerate-go distance equals the accelerate-stop distance (i.e. shortest takeoff field length).
When is a runway considered to be wet ?
Runway is wet if no significant water (less than 3 mm).
When is a runway considered to be contaminated ?
When more than 25% of the runway surface area (whether in isolated areas or not), within the required length and width being used, is covered by surface water more than 0.125 in (3 mm) deep, or by slush or loose snow equivalent to more than 0.125 in (33 mm) of water.
What’s the definition of stopway ?
An area beyond the actual runway length capable of supporting the airplane in an aborted takeoff, which can be used as part of the available accelerate-stop distance.
What’s the definition of clearway ?
An obstacle-free area beyond the actual runway length which can be used as part of the accelerate-go distance available on a dry runway. No clearway credit is allowed on a wet runway.
What’s the definition of V2 ?
Take off safety speed. The target speed to be attained at or before reaching 35 ft above the take off surface following an engine failure.
What’s the definition of Vse ?
The recommended airspeed for single-engine climb in the enroute (clean) configuration.
What’s the benefit of taking off with 10 flaps ?
Results in higher climb gradients, and will permit higher takeoff weights when climb limited or obstacle clearance limited.
