Need help calculating the basic things.

I am an accuracy nut, I like this the best it is what I fly by. It is intended for the A320 but there are things that you can use to apply to your everyday flying like how to calculate TOD = Top Of Decent. A simple way to calculate it is: Use 6.5 miles per minute (at Mach .65 in descent) as the basis. If you are cruising at 33,000 ft. and wish to descend to 5,000 ft. at the next waypoint, at a descent rate of 1,800 ft./min., you need to figure the time to descend 28,000 ft. (33,000 - 5,000). …

How to compute the TOD (Top of Descent) - Thumb rule

Hi There, there is an easy thumb rule for descents, that is important to know for pilots and ATC Controllers as well: subtract the current altitude from the target altitude, eg 30000ft - 10000ft = 20000 divide the result by 1000 and multiply with 3 and you will get the miles 20000 : 10000 = 20 x 3 = 60 miles so you have to start the descent 60 miles away from the point where you plan to be at 10000 IMPORTANT: - descent rate is no less than 2000ft/min - speed is not higher than 280kts …
