E6B Flight Computer
Solve core E6B flight-planning checks: wind correction for a desired course and quick density altitude from pressure altitude and outside air temperature.
Wind Triangle
Density Altitude
Hotter-than-ISA air raises the effective altitude
The quick E6B approximation uses ISA temperature at pressure altitude and adds about 120 ft for each degree Celsius above standard.
Altitude comparison
+1800 ft correction
