Is stall speed the same as take off speed?
When taking off, an aircraft typically does not exceed the maximum angle of attack for its current speed; if it did, the aircraft would stall and likely crash. The aircraft instead accelerates to a speed in excess of the forward stall speed of the aircraft, and then gently pitches upward to gain altitude.
What is aircraft stall?
The stall is a breakdown of the smooth airflow over the wing into a turbulent one, resulting in a decrease in lift. The lift will no longer fully support the aeroplane’s weight, and the aeroplane sinks.
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 makes an airplane stall?
A stall occurs when the angle of attack of an aerofoil exceeds the value which creates maximum lift as a consequence of airflow across it. However, when flying straight and level with a particular aircraft mass and prevailing density altitude, for every wing angle of attack there is a corresponding indicated air speed.
What is the stall speed of a commercial jet?
For jet airliners the stall speeds may range from around 100 knots when light (~185 km/h, ~115 mph) to maybe 130 knots (~240 km/h, ~150 mph) when loaded⁴.
How do you calculate the stall speed?
Stall speed inc. in turn = old speed x square root of load factor e.g. in 60 degree AOB turn load factor is 2, root of 2 = 1.414, if old speed is 100 kts new speed is 141.4 kts. 3. Stall speed increases if load factor increases, decreases if load factor decreases.
How to calculate the mass of an aircraft that will stall?
Select “Lift” on the right side and see how the lift changes with speed. If you divide the lift by the gravitational acceleration of the selected planet (yes, you can run Foilsim on Venus or Mars, too – on earth that would be 9.806 m/s²), you get the mass of the aircraft that will stall at the selected speed.
How fast do you fly when stalling?
Most of the planes I fly tend to stall in the 40-45MPH range so I tend to keep the speed up above 60. Also, when you approach a stall, airspeed indicators tends to bounce around a bit or start moving fast and the pitch is changing so “knowing” the exact speed is not real useful.
Why do planes stall on landing?
On landing, ground effect, flap setting, and air density, remaining fuel can impact the exact stall speed so you just let the plane settle as you approach a close approximation of that speed as you cross the threshold. Also, the stall warning, that irritating little buzz, will come on and off as you start getting close to the stall speed.
