The formula to calculate the Flight Length (FL) is:
\[ FL = FS \times FT \]
where \( FL \) is the flight length, \( FS \) is the flight speed, and \( FT \) is the flight time.
The flight length is the total distance traveled by an aircraft during a flight. It is calculated by multiplying the flight speed by the flight time.
Let's assume we have the following values:
Step 1: Multiply the flight speed by the flight time:
\[ FL = 500 \times 3 = 1500 \text{ miles} \]
Therefore, the Flight Length (FL) is \( FL = 1500 \) miles.
