# What is the stall speed of your training airplane in a 60 degree bank with flaps up?

Contents

Assuming a stall speed of 50 knots in level flight, at 60 degrees angle of bank the stall speed will increase by the square root of the load factor +2 (√2), which is approx 1.4. This means that, at 60 degrees angle of bank, the stall speed is increased by 40% to 70 knots.

## What is the stall speed of a Cessna 172 in a 60 degree bank with flaps up?

So if the stall speed (Vs – clean config) in your Cessna 172 is 48 knots, then your stall speed at 60 degrees of bank is 48 knots X 1.41, which equals just over 67 knots.

## Do flaps increase stall speed?

Changes to the airfoil geometry from high-lift devices such as flaps or leading-edge slats increase the maximum coefficient of lift and thus lower stall speeds.

## How do you calculate the stall speed of an aircraft?

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 load factor in a 60 degree banked turn?

The load factor is the vector resultant of gravity and centrifugal force. For example, in a level altitude, 45° banked turn, the resulting load factor is 1.4; in a level altitude, 60° banked turn, the resulting load factor is 2.0.

## How many G’s is a 45 degree bank?

Load factor and accelerated stalls: A constant-altitude turn with 45 degrees of bank imposes 1.4 Gs, and a turn with 60 degrees of bank imposes 2 Gs.

## Why does stall speed increase with altitude?

At higher altitudes, the air density is lower than at sea level. … For example, the indicated airspeed at which an aircraft stalls can be considered constant, but the true airspeed at which it stalls increases with altitude. Air conducts sound at a certain speed, the “speed of sound”.

## What is stall speed dirty?

Power off stall (Approach stall)

Used to simulate a stall while in a low speed “dirty” configuration(flaps out, gear down, etc.) such as while on downwind, base or final while prepping to land.

## Why are flaps down during landing?

Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons.

## Should flaps be down for takeoff?

The next time you fly in an airliner, watch the wings during takeoff and landing. On takeoff, we want high lift and low drag, so the flaps will be set downward at a moderate setting. During landing we want high lift and high drag, so the flaps and slats will be fully deployed.

## Does landing gear affect stall speed?

Configuration. Flaps, landing gear, and other configuration devices can affect an airplane’s stall speed. Extension of flaps and/or landing gear in flight will usually increase drag. Flap extension will generally increase the lifting ability of the wings, thus reducing the airplane’s stall speed.

## Can an airplane stall at any speed?

The only dangerous aspect of a stall is a lack of altitude for recovery. … Stalls occur not only at slow airspeed, but at any speed when the wings exceed their critical angle of attack. Attempting to increase the angle of attack at 1g by moving the control column back normally causes the aircraft to climb.

## What is a rate one turn?

By definition, a rate one or standard rate turn is accomplished at 3°/second resulting in a course reversal in one minute or a 360° turn in two minutes. A rate one half turn is flown at 1.5°/second and a rate two turn at 6°/second.

## Why does lift increase with speed?

So when plane’s speed increases, the speed of the air over the wing does too. … This means that the pressure above the wing drops. Since the air below the wing is moving more slowly, the high pressure there will push up on the wing, and lift it into the air.

## Does stall speed increase with load factor?

A load factor greater than 1 will cause the stall speed to increase by a factor equal to the square root of the load factor. For example, if the load factor is 2, the stall speed will increase by about 40%.

## What is the critical angle of attack?

The critical angle of attack is the angle of attack which produces the maximum lift coefficient. This is also called the “stall angle of attack”. … At the critical angle of attack, upper surface flow is more separated and the airfoil or wing is producing its maximum lift coefficient.
