different types of propellers are Fixed Pitch Propeller, Variable Pitch propeller, Adjustable Pitch propeller, etc...

# data[].attributes.body
fine pitch propeller has more revolutions and is used for takeoff. Coarse propellers is used for pitch control and cruise flight

# data[].attributes.body
Feathering is when one engine is off and the turning blades are in extreme coarse pitch position and stop turning

# data[].attributes.body
Feathering is when the blade pitch increased so that the chord line of the blade is parallel to the on-coming airflow.

# data[].attributes.body
Propellors provide push and pull as it moves

# data[].attributes.body
the angle of a fixed pitch propeller blade is not adjustable by the pilot

# data[].attributes.body
Propellor reversing is used to stop an aircraft when landing. It slows down speed and eventually stops the aircraft.

# data[].attributes.body
Practical pitch is the distance the propeller travels in the air in one revolution and the forward motion is less than theoretical pitch

# data[].attributes.body
When one engine is off, the propeller is feathered meaning the turning blades are in the extreme coarse pitch position

# data[].attributes.body
The Fixed Pitch cannot be adjusted

# data[].attributes.body
Pitch- the distance in feet a propeller travels forward in one revolution

# data[].attributes.body
There can be fixed pitch propellers and variable propellers.

# data[].attributes.body
A propellers blades angle from the hub to its tip

# data[].attributes.body
The propeller is designed to push air backwards as it moves forward along the corkscrew path.

# data[].attributes.body
Propellers can be pitched to unorthodox degrees for situational uses.

# data[].attributes.body
Propellers are located at the front of the plane

# data[].attributes.body
Propellers can have a fixed pitch or a variable pitch

# data[].attributes.body
The propeller provides thrust on an aircraft.
