FAQ: What Is Vso In Aviation?

What does VSO mean in aviation?


Term Main definition
VSO Stalling Speed or Minimum Steady Flight Speed in the Lan

What is VSO and VS1?

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.

What is 1.3 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 speed is VA in aviation?

The design maneuvering speed ( Va )is the speed at which the airplane will stall before exceeding its design limit-load factor in turbulent conditions or when the flight controls are suddenly and fully deflected in flight. Under these conditions the airframe experiences an increase in “G-force” or “load factor.”

What is VX in aviation?

VX is the speed at which the airplane achieves the greatest gain in altitude for a given distance over the ground. It is usually slightly less than VY, which is the greatest gain in altitude per unit of time. The specific speeds to be used for a given airplane are stated in the FAA-approved AFM/POH.

How is VA aviation calculated?

Pilots may remember from their written exam that VA -NEW = VA √ (WNEW/WMAX-GROSS) as the way to calculate the corrected (new) maneuvering speed due to operating at a weight less than the maximum gross weight. NOTE: This formula is for calculating the VA change about the pitch axis; however, it can be used for all axes.

What is VSO speed?

VSO. — Stall speed in landing configuration. Lower limit of white arc.

Is VS and VS1 the same?

VS2 vs VS1: What’s the Difference? A VS1 diamond is a high clarity grade with no visible inclusions and only small, hard-to-identify inclusions under 10x magnification. Whereas a VS2 diamond will have eye-visible inclusions only 5 percent or less of the time, and only in larger diamonds above 1 carat.

What is the difference between VA and VNO?

Va is the maximum speed the aircraft can be stalled without exceeding the limit load factor (3.8g for normal category airplanes). Vno is based on the maximum speed at which the aircraft can encounter a 50fps vertical gust and not exceed the limit load factor.

What speed should I land?

For a short-field landing in smooth conditions, make the power-off approach at 60 KIAS with full flaps. (Slightly higher approach speeds should be used under turbulent conditions.)” For normal landings on longer runways, final approach should be flown at 70-80 knots without flaps, or 60-70 knots with full flaps.

Is VREF same as Vapp?

Vref is the actual touchdown speed at which the wheels should make contact. Vapp is your approach speed, and is adjusted for any wind component you might have. You drop from Vapp to Vref usually by just going idle at a certain point in the flare. Vref is the speed over the threshold, not the touchdown speed.

At what speed does a Cessna land?

The 172S POH recommends 61 knots for a final approach speed for a short field landing, which is 9 knots faster than 1.3 X Vso. As for the Cirrus SR22T, they recommend 80-85 knots on final, and 79 knots crossing the threshold. If you do the FAA’s math for final approach, they would say 83 knots (1.3 X 64).

What is V1 V2 VR?

This is known as V1. The second speed is when the nose should be raised and the airplane is rotated into the climb attitude, known as Vr. V2 is the speed at which the airplane will climb in the event of an engine failure. It is known as the takeoff safety speed.

What is V2 in aviation?

V2: Takeoff Safety Speed. V2 is the minimum speed that needs to be maintained up to acceleration altitude, in the event of an engine failure after V1. Flight at V2 ensures that the minimum required climb gradient is achieved, and that the aircraft is controllable.

What is load factor Aviation?

In aeronautics, the load factor is the ratio of the lift of an aircraft to its weight and represents a global measure of the stress (” load “) to which the structure of the aircraft is subjected: where is the load factor, is the lift.
