Use these tips to reliably go beyond the book and ensure adequate performance in high-density-altitude operations.

By Thomas P. Turner

It happens every summer. Temperatures rise and with them so does density altitude. It may seem we should simply avoid flying when the density altitude (DA) creeps up, but this would be very short-sighted—although there are some hazards warranting a delay when the air heats up (thunderstorms and desert turbulence among them), the fact is we can safely fly in most high-density-altitude conditions. Doing it, however, requires some technique and some compromise.

We all learned the basics of density altitude when we first learned to fly. But what are the practical techniques necessary to maximize airplane—and pilot—performance when hot and high? And when do we need to employ them? …
