Feathering

Feathering

News: A preliminary report by the Aircraft Accident Investigation Commission of Nepal on the crash of a Yeti Airlines ATR 72-500 brought to light that the propellers of the plane were found in an unusual “feathered” position.

About:
 Sometimes an aeroplane’s engine stops working while it’s flying. In an aeroplane with a propeller, the pilot can change the angle of the propeller blades so they cut through the air more efficiently. This is called “feathering” the propellers.
 Feathering helps the aeroplane glide farther and stay at a safe speed. When pilots have to make an emergency landing, they often use feathering to help them. If the propellers keep spinning even when the engine is off, it can be dangerous if the aeroplane is flying low, but it can actually help restart the engine if the aeroplane is flying high.
