What should be done when an envelope is over temperature?

When an envelope is over temperature, the primary concern is safety and the structural integrity of the lighter-than-air craft. Landing immediately is an appropriate response because an overheated envelope can lead to a loss of control or even structural failure. This situation poses a significant risk to both the passengers and the aircraft.

While adjusting burner settings or ascending to a cooler altitude might seem like potential solutions, they may not adequately address the immediate danger of an overheated envelope. If the temperature is excessively high, these actions might not provide sufficient cooling or could even exacerbate the issue. Evacuating passengers is typically considered a last resort or in extreme emergencies, but it does not address the immediate necessity of safely landing the craft to prevent a more severe outcome.

In summary, the most responsible course of action when faced with an overheated envelope is to land the aircraft as quickly and safely as possible, ensuring the safety of everyone on board.
