What is VS0 speed?

stalling speed
VS0 means the stalling speed or the minimum steady flight speed in the landing configuration. VS1 means the stalling speed or the minimum steady flight speed obtained in a specific configuration. VSR means reference stall speed. VSRO means reference stall speed in the landing configuration.

Is a higher or lower stall speed better?

A higher stall speed will mean that you will be closer to stalling at any given airspeed. A lower stall speed is desired so that you can maintain a safety margin between your airspeed and the stall speed. A lower stall speed also means the aircraft can fly and land at a lower airspeed and, in turn, ground speed.

What is 1.3 times VSO?

1.3 Vso is 1.3 times the stalling speed, or the minimum steady flight speed, in the landing configuration with flaps down, engine at low or idle power as it would be just prior to touchdown.

What is normal stall speed?

In general, the desired stall speed should be 500-700 RPM below the engine RPM at peak torque. This ensures a margin for application for the torque converter to take off.

What are the V-speeds for a Cessna 172?

N12874 C-172 Skyhawk

V-Speed MPH
Va: (Maneuvering Speed) 112MPH
Vfe: (Max flap extended speed) 100MPH
Vno: (Max structural cruising speed) 145MPH
Vne: (Never exceed speed) 182MPH

Can V1 be higher than VMCA?

V1 is also the minimum speed at which a pilot can continue a takeoff after an engine failure. If an engine failure is detected after V1, the takeoff must be continued. This implies that the aircraft must be controllable on ground. Therefore, V1 is always greater than VMCG.

What is a high speed stall?

A high speed stall is something that happens close to, but still below, Mach 1. It involves supersonic flow over the wing, but the whole airplane still travels at subsonic speed.

How is VSO 1.3 calculated?

The 1.3 Vso CAS at max gross weight is all the descriptor of a single variable. There is no math done here. Look up the number that is 1.3 Vso CAS at max gross. Multiply that by the square root of the actual landing weight over the max gross weight and you’ll get the 1.3 Vso CAS at the landing weight.

What happens if stall speed is too low?

Converter stall speed must be high enough to put the engine into the torque range where it can most efficiently launch the car. If converter stall speed is too low, the car will be lazy leaving the line; if too high, there’ll be excessive high-gear slippage—either case adds time to your e.t.

What is the best stall speed for towing?

If your motor generates more power in the lower RPM range, you’ll want to select a converter that stalls at the beginning of that RPM range. If you use your vehicle for towing, make sure your torque is around 1800 RPMs.
