love the app and the website. im a pilot and love the wind/radar/metar/taf's etc.
in the airgram detailed forecast the winds aloft are given in Hpa. in aviation we use MSL for winds aloft. pilots would need to do a complicated conversion every 100 NM to be accurate especially when crossing frontal boundaries or areas of large pressure changes. 800hpa isnt always 6400ft MSL and 900hpa isnt always 3000ft msl. some places that you click on...lets say a mountainous area...3000ft (900hpa) is under the ground but the chart is still showing a wind barb for that altitude.
The same thing goes for the wind overlay where you can select a pressure setting (altitude) and it shows the wind streams with color coded velocity
this could be a smaller issue than im thinking it is because a lot of pilots are saying how awesome this site is.
any light that could be shed on this would be greatly apriciated...because i could just be way over thinking this
