Performance Flashcards
When landing with less than full flaps, where can the appropriate Vref speed be obtained?
On the FLT REF page of the display controller or in the landing speed schedule table, Performance Handbook.
What is the definition of the accelerate-go distance in the G550?
The required distance to accelerate with both engines operating to the critical engine failure speed, sustain an engine failure, and continue the takeoff to a height of 35 ft AGL on a dry runway or 15 ft AGL on a wet runway.
What is the definition of the accelerate-stop distance in the G550?
The required distance to accelerate with both engines operating to the critical engine failure speed (V1), initiate actions to abort the takeoff, and come to a complete stop.
What is the reference accelerate-go distance in the G550
The available distance obtained by correcting actual runway length for effects of clearway, slope, wind, anti-icing and runway conditions (G550 is calculated for both wet and dry runways)
What is the reference accelerate-stop distance in the G550
The distance obtained by correcting the accelerate-stop distance available for the effect of slope, wind, anti-icing, ground spoilers, and anti-skid operation (G550 adds ECS bleeds to the calculations)
What is takeoff decision speed in the G550 (V1))?
The speed from which the decision to continue the takeoff results in a takeoff that will not exceed the available accelerate-go distance, or from which a decision to bring the airplane to a full stop will not exceed the accelerate-stop distance available.
In the event of an engine failure, this speed takes into account the pilot reaction time of 2.0 seconds, including the pilot’s first action after recognizing the engine failure.
For and all engine rejected takeoff, this is the speed at which the pilot performs the first action to abort.
When is a runway considered wet?
When it is well soaked but without significant areas of standing waters.
A runway is considered well soaked when there is sufficient moisture on the runway surface to cause it to appear reflective.
Runways which are damp with moisture present but not reflective are considered dry.
What is considered a contaminated runway?
When 25% or more of the surface is covered by surface water at least 0.125 inches deep, or by slush or loose snow equivalent to 0.125 inches of water.
When can FLEX takeoff power be used?
Dry or wet, hard surfaced runways, and the takeoff performance computed is limited to takeoffs for nil or uphill runway slopes, and no wind or headwind conditions only.
What is V1 min?
The lowest usable V1 speed resulting in the shortest accelerate-stop distance but longest accelerate-go distance (cannot be less than Vmcg)
What is V1 max?
The highest usable V1 resulting in the shortest accelerate-go distance but longest accelerate-stop distance (cannot be greater than Vr).
What is rotation speed (Vr)?
G550 rotation speed is the speed at which rotation to the takeoff attitude is initiated, performance data is based on 75 lbs of pull force within 1 second.
What is V2 speed?
V2 takeoff safety speed is the target to be attained at the 35 ft height following an engine failure.
If an engine failure should occur after passing V2 on takeoff, it is recommended that the speed at the time of the engine failure be maintained (up to V2+10 kts)
What is Vse enroute climb speed?
Vse is the recommended airspeed for the single-engine climb in the enroute (clean) configuration.
What approach speed should be used if strong winds are present?
Add to Vref 1/2 of the steady state wing plus the full gust to a maximum additive of 20 kts, and Vref is still the target speed at the threshold.
