Another example of Andrew thinking he’s funny.
Wow lots of different and complicated ways of computing this!!
I like to keep it simple and through this forum have found these two simple formulas!
Total Distance / 7 = Flight Level.
Eg 240/7= 34 = FL340.
TOP OF DESCENT
FL / 3 = Distance To Go ( DTG) when to start your descent
eg FL340 / 3 = 113 nm.
Above are a rule of thumb and need to be adjusted for aircraft weight, traffic conditions etc but works in most cases!
- WMKK-WSSS TOTAL DISTANCE = 200 nm
200/7= 28.57= FL290
- CALULATE TOD*
290/3 = 96.6
Start your descent when 97 nm from dest.
Spot on there!
Keeping it simple. Like.
Thanks,Ya’al! See ya flying sometime.(Maybe)
Brilliant. That is so much easier to remember. Thank you.
