VDP's

[Mr Biggelsworth]

Does anyone remember how to get the VDP from using both time and distance? I can't remember the two formulas; much appreciated.

 

[Flysher]

distance is HAT divided by 300, I forget what the time equation is too.

There is a wonderful gizmo on this board called a search function:

Try it some time.

Nice comeback(for a playground.)

If after 130 posts you don't know about the search function, now you do. If you do know about the search function and just want someone to do your research for you; well, you're just too danged lazy to live.

Time:

10% of the HAT at the MAP. Subtract that from the time from FAF to MAP

Example:

400 foot agl at MAP
Time from FAF to MAP: 2 minutes

400 feet * 10% = 40 (seconds)

2 minutes subtract 40 seconds = 1 minute and 20 seconds

PDP= 1 minute and 20 seconds after passing FAF.

It's actually HAT/GS(in ft/nm) if you want to be technical

If you want to be technical...what factor do you add to figure your theory out (HAT/ GS) ? Never heard it.
