In the northern hemisphere, air flows clockwise|cw around a high presssure area, and counterclockwise|counter-clockwise|ccw around a low pressure area.
Geometric pitch is the theoretical distance a propeller should advance in one revolution; effective pitch is the distance it actually advances.
If the holder of an airplane SEL pilot certificate applies for a multi-engine class rating, the pilot will not need to take a written test, nor are there any minimum flight hour|hour requirements.
The best rate of climb speed with one engine inoperative (Vyse) is indicated with a blue radial line on the airspeed indicator.
Low propeller pitch is a smaller|small bite of air, high propeller pitch is a larger|large|big bite of air.
In cruise flight with a constant-speed propeller, an increase in airspeed will increase the pitch of the propeller, and a decrease in airspeed with increase the pitch of the propeller.
A clockwise turning propeller will have a tendency to yaw the aircraft to the left, and roll the aircraft to the right.
