# How to Calculate Speed Based on the Pitch of the Propeller

## What is the formula to calculate speed based on the pitch of the propeller?

1) Distance ÷ Time

2) Pitch ÷ Time

3) Cannot be determined

## Answer:

The formula to calculate speed based on the pitch of the propeller is Pitch ÷ Time.

The speed of an aircraft can be calculated based on the pitch of the propeller. The pitch of a propeller refers to the distance the propeller would move in one revolution if it were moving through a soft solid. To calculate the speed, you need to divide the pitch by the time taken for one revolution of the propeller.

For example, if the pitch of a propeller is 50 inches and it takes 1 second to complete one revolution, the speed would be 50 inches ÷ 1 second = 50 inches per second.

By knowing the pitch of the propeller and the time taken for one revolution, pilots and engineers can determine the speed of the aircraft accurately. This calculation is crucial for flight planning, efficiency, and performance evaluations of the aircraft.
