Can you land a helicopter without engine?
In normal powered helicopter flight, air is drawn into the main rotor system from above and exhausted downward, but during autorotation, air moves up into the rotor system from below as the helicopter descends. It is the means by which a helicopter can land safely in the event of complete engine failure.
How does autorotation work on a helicopter?
Autorotation is a condition of helicopter flight during which the main rotor of a helicopter is driven only by aerodynamic forces with no power from the engine. It is a manoeuvre where the engine is disengaged from the main rotor system and the rotor blades are driven solely by the upward flow of air through the rotor.
How do you crash land a helicopter?
With the engines turned off or failing, pilots must use a technique called autorotation to land the helicopter safely. Within the first few seconds of the engines failing, the pilot must adjust the helicopter’s position to avoid losing control altogether, which pretty much turns out like what you see in the movies.
Why do pilots say easy victor?
One of the phrases they learn is “easy victor” which means prepare to evacuate. According to a former flight attendant, the pilot won’t just blurt it out. There will be some warning and you’ll know there is a problem long before. So you shouldn’t worry about listening out for it when you’re on board, he said.
What do you do after a plane crash?
Get out of the plane as quickly as possible. Fatality rates increase significantly after the first 90 seconds following a plane crash. Follow the instructions of the cabin crew, but if they’re dazed, disoriented, or dead, don’t wait. Get out of the cabin as fast as you can and as far from the plane as possible.
