To calculate the required rate of descent, first, determine the time it will take to travel 10 nautical miles while maintaining a ground speed of 300 knots. Since one nautical mile is approximately equal to one minute of travel at one knot, the time to travel 10 nautical miles at 300 knots can be calculated as follows:

10 nm ÷ 300 knots = 1/30 hours, which converts to 2 minutes.

Next, you need to convert the altitude you wish to descend. The descent is from 2500 feet and we need to calculate how fast you need to descend to cover that altitude while reaching the ground in 2 minutes.

To find the required rate of descent in feet per minute, divide the total descent by the time in minutes:

2500 feet ÷ 2 minutes = 1250 feet per minute.

However, the earlier calculation represents a different scenario with descent not yet matching the ground speed and time adequately. Instead, for a more accurate calculation relating to descent angles, you can take the speed (in feet per minute) and factor in the horizontal distance to ensure descent is managed correctly considering both speed and depth.

To maintain a safe and standard descent rate while still managing the profile, achieving a target like
