Why are there oxygen masks on airplanes?
When cabin pressure drops in a plane, passengers need the masks in order to receive a sufficient flow of oxygen. The masks prevent hypoxia, when the body lacks enough oxygen to maintain normal physiological function.
What does it mean when an airplane has stalled?
angle of attack
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.
Why do commercial flights turn / bank so?
They actually limit it to 25 degrees of bank when using a flight director, mainly for passenger comfort. It can be impressive when looking out the window and seeing the ground, but don’t worry, the airplane is more than designed for it! This is used mainly at lower altitudes where there are lots of airplanes.
How often does an airliner roll into a bank?
An airliner will roll relatively smoothly into a bank angle of up to 30° (which can seem steep), and a rate of turn (change in compass heading) of between 3° and 1.5° per second. You often don’t feel the roll, but will observe the bank by looking out the window.
How many degrees of bank does an airplane need to have?
Even at the most basic Private Pilot (US) standard in a small airplane the minimum required is to demonstrate 45 degrees of bank and up to 60 is allowed for the aircraft. Aerobatic airplanes can do 70-80 degrees of bank while maintaining level flight, they can even flip over 180 degrees and fly upside down.
How long does it take for an airplane to turn?
Airplanes are expected by air traffic control to turn at a “standard rate of turn” which is 3 degrees per second. This will provide a 90 degree turn in 30 seconds.
