## How do you manually calculate flight times?

Basic Calculations

1. Time T = D/GS. To find the time (T) in flight, divide the distance (D) by the GS. The time to fly 210 NM at a GS of 140 knots is 210 ÷ 140 or 1.5 hours.
2. Distance D = GS X T. To find the distance flown in a given time, multiply GS by time.
3. GS GS = D/T. To find the GS, divide the distance flown by the time required.

3. Calculate: 489.3/589.5 = 0.83 Mach.
