Why is VLE VLO extension 140 KIAS but VLO retraction is 109 KIAS in the Seminole?
Why is max gear retraction speed 109 KIAS and extension speed 140 KIAS? Retraction (VLO retract 109K), is slower than extension because the nose wheel will unlock and ram air will push the nose wheel back into the wheel well. Any faster speed and it could damage the nose gear.
What is VLO speed?
VLO is the airspeed at which the landing gear can be safely operated—extended or retracted. VLE is the maximum speed at which you can fly with the gear extended.
What airspeed is va?
Design maneuvering speed
VA. — Design maneuvering speed. The highest safe airspeed for abrupt control deflection or for operation in turbulence or severe gusts. It does not allow for multiple large control inputs.
What is accelerate stop distance?
Accelerate-stop distance is the runway length required to accelerate to a specified speed (either VR or VLOF, as specified by the manufacturer), experience an engine failure, and bring the airplane to a complete stop.
What is Max structural cruising speed?
Maximum structural cruising speed — the highest speed that you can safely fly in smooth air — is shown as the upper limit of the green arc on the airspeed indicator. If you fly above VNO — in the yellow arc or “caution range” — and you encounter air that is not smooth, you could cause damage to the aircraft.
How is VNo calculated?
I also found out that “VNo is a calculated speed based on the wing loading of the aircraft. For utility aircraft it is 33 times the square root of the wing loading. For aerobatic aircraft it is 36 times the square root of the wing loading.”
What does the V mean in V speeds?
Your Aviation Acronym Decoder begins with some talk about Velocity. V is for Speed. The “V” is from the French word ‘Vitesse’ which means ‘speed’ or ‘rate’. Important aviation Airspeeds are identified and defined using standard terms. Scientists and Engineers refer to Airspeeds as ‘V’ Speeds.
