100 Knots =115 MPH • 100 MPH = 87 knots
“V” stands for Velocity • VNE = Never Exceed Speed = Red Line VNE=159 Knots
VA = Maneuvering speedNot depicted on airspeed indicator • maneuvering speed, the speed at which full and abrupt control movement can be applied without the possibility of causing structural damage, and, separately, the maximum speed at which the aircraft can be flown in turbulent conditions.
White Arc is Flap Operating Speed • Bottom of White Arc is VS0…Stall speed with flaps fully extended Top of the white arc is Vfe…Max flap extension speed
Green arc is the normal operating range • Bottom of Green band represents • Vs: The Stall speed with the flaps retracted Top of the Green Band is Vno Vno is maximum structural cruising speed
Yellow arc The yellow range is the range in which the aircraft may be operated in smooth air, and then only with caution to avoid abrupt control movement. • Yellow arc = Vno through Vne
Vx Best angle of climbMost altitude gained over a given distance.Used short term to clear an obstaclepoor visibility and poor engine cooling • Cessna 172 VX = 62Kts Vx
Vy… Most altitude in shortest amount of time • Cessna 172 Vy =74 Kts VY
Best L/D • Represents best Glide Speed…Used for best gliding speed if you have an engine failure • Best L/D in a Cessna 172 at gross weight is 68 Kts
TAS= 110Kts -15 Kt headwindWhat is your groundspeed ? 15 Knots
TAS = 65 Knots with 25kt tailwindWhat is your groundspeed? 25Knots
