What action is most appropriate when an envelope over-temperature condition occurs?

• A. Land as soon as practical
• B. Climb to a higher altitude
• C. Decrease burner usage slowly
• D. Call air traffic control

Answer: (A)

When the envelope is overheated, the fabric and the air inside are stressed and continued heating increases the risk of damage or failure. The safest, most effective action is to land as soon as practical so you can descend into cooler air and reduce the heat load on the envelope promptly. Climbing to a higher altitude might put you in cooler air, but it doesn’t remove the heat quickly and can complicate control and descent. Decreasing burner usage slowly delays cooling because heat remains being added, so it doesn’t address the immediate risk. Calling air traffic control doesn’t solve the overheating issue on its own; the priority is to land and manage the envelope temperature.
