Density Altitude and Useful Load
Density Altitude and Useful Load, When Performance Margins Disappear On paper, useful load tells you what you’re allowed to carry. In the real world, density altitude decides whether the airplane can actually perform while carrying it. Density altitude is pressure altitude corrected for temperature (and to a lesser extent humidity), and it describes how “thin” the air really is. As density altitude increases, the airplane’s
