# What is the formula for stall speed?

## What is the formula for stall speed?

We know that for any level flight (not climbing) the amount of lift must be equal to the weight of the aircraft, thus if all up weight is lower then the amount of lift required is less too. To calculate the new stall speed: Vs new = Vs Old Weight × √(New Weight / Old Weight).

What is the formula of stalling?

Since we know that the density of air decreases with altitude and from the formula V = SQRT ( 2* L / (Cl * p * S ), we see that density is inversely proportional to stall speed we can say that stall speed does increase with an increase in altitude.

### At what speed does a plane stall?

Aeroplanes, or airplanes if you’re American, need to maintain a certain speed to allow flight. Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph).

What is the stall speed of an airplane in a 30 degree bank turn if the level stall speed is 100 knots?

What is the stall speed of an airplane in a 30 degree bank turn if the level stall speed is 100 knots? 108 knots.

#### What is stall velocity?

Stall Velocity is lowest velocity a plane can fly to maintain level flight condition. The stall velocity is dependent on the airplane’s weight, altitude, Wing span, coefficient of lift, Density, Airspeed Indicators are used to predict stall conditions in airplanes.

What is the stall speed of a torque converter?

around 1,800-2,000 rpm
Stock torque converters generally have a stall speed around 1,800-2,000 rpm. Higher stall speeds become necessary when horsepower and torque happen at higher rpm ranges.

## What is a high speed stall?

An accelerated stall where the stalling angle is achieved at a higher-than-normal stalling speed, as in maneuvers. The new stalling speed under acceleration is equal to the normal stalling speed multiplied by the square root of applied acceleration.

How does stall speed change in a turn?

When you turn, you need to increase your total lift to maintain altitude. You increase your total lift by increasing your angle of attack, which means you’re closer to stall than you were in wings-level flight. And, your stall speed increases in proportion to the square root of your load factor.
