Someone wanna check this over for me? I've been working on it for a while and think its pretty close but since my tracks don't provide a lot of info I've had to make it up as I go along. If someone could review it and let me know if its correct or all BS I'd appreciate it.

 

Congrats on getting the formula to calculate DA, thats such a bitch!

I see that the formula you used does not add the actual over sea elevation...
just that..

 

Thanks I think I fixed it now

 

As an alternative...

For true DA, you need the station pressure, which can be plugged in here:

Then, take that and plug it in here with the air temp. and dewpoint:

The altimeter setting is what is reported as the barometer readings on most weather sites unless it specifically shows it as station pressure. Hope this helps. Take care. Dave
