Default Re: VDP. Why it isn't it depicted in all charts?

450 ÷ 10 = 45
2:45 – 45 = 2:00

2 minutes from the FAF is the VDP.

probly has nothing to do with why its not depicted on the chart, but this works great if you dont have DME

If you do have DME, just divide the HAT by 300.

example:
HAT=600
600 ÷ 300 = 2 VDP is 2 DME from MAP
How much do you actually use this?
