![]() ![]() Nautical miles per minute times descent angle times 100 gives vertical velocity in feet per minute. It takes 200 feet at 2°, 300 feet at 3°, and so on.įlight levels divided by nautical miles equals gradient. It takes 100 feet vertically to climb or descend at a 1° gradient in 1 nautical mile. The distance traveled along an arc is equal to the arc radius times the arc angle divided by 60.Ī holding pattern teardrop angle can be found by subtracting 70 from the airplane's ground speed (in knots) and dividing the result by the holding pattern leg's distance. At low arc distances, this formula tends to be too high. The bank angle required to fly an arc is equal to 30 times the aircraft's turn radius (nm) divided by the arc's radius (nm from the station). ![]() To provide circling offset when approaching from the opposite runway, turn 30° away from heading, time for 60 seconds (Category D) or 53 seconds (Category C), and then turn to parallel the runway on downwind. To provide circling offset when approaching a runway at 90°, overfly the runway and time for 20 seconds (Category D) or 15 seconds (Category C) before turning downwind. Turn radius for a 25° bank angle = (nm/min) 2 / 9. ![]()
