What does your flight instructor pound into your brain this time of year? (At least we hope your flight instructor is pounding this into your brain.) Density altitude.

We’re not going to stray from that path. Hot weather and airplanes have a long and complicated relationship, and you need only look on YouTube to see lots of evidence of what happens when you don’t calculate density altitude. (This clip, which shows in-cockpit footage from a 2012 crash, is particularly educational. The four occupants of the Stinson did walk away from the crash.)

That’s why our Technique and Weather articles this month are devoted to density altitude. You can’t learn too much about it, particularly if you are a flat-land pilot who may be tempted to assume—incorrectly—that density altitude is something you don’t have to think about.

Also in our August issue:

  • Energy management: Does throttle control altitude or airspeed? What role does the elevator play? We break down energy principles of motion control in four steps.
  • Keep yourself sharp: Now that you’re a certificated pilot, just how sharp are you? Here are some ways to keep yourself in the student mindset.
  • Buddy system: Why should you be a safety pilot? We tell you all the reasons.

Also: A marriage made in aviation heaven; an interview with Living in the Age of Airplanes and One-Six Right director Brian J. Terwilliger.

The August digital edition goes live on June 23. Learn more about how you can get the magazine delivered to your tablet, computer, or mobile device here.
