E6B Flight Pro

The wind low portion is plotting the direction the wind is going to, not the direction from. Wind is measured from the direction it is blowing from. Hence a head wind of 270 means to land on runway 27 in a head wind (blowing from), not a tail wind (blowing to).

Update review, the developer has done a fantastic effort on this app-I would fly with it in my flight bag. I have crossed checked with my iphone 14+ both front and rear sides against real analog E6-b's and found it to be correct. Just a user note: the IAS calculator tab is of little use from my point of view. The speed tab should have KTS to MPH conversion. Lastly if the end user could re-arrange the order of each tab ie-group pressure alt, density alt, fuel mass in one group then a lot of operational safety information is in front of the pilot before take-off.
