Where is the parachute panel located in a hot air balloon?

The parachute panel in a hot air balloon is located at the top of the envelope. This placement is crucial because the panel allows for the controlled release of hot air from the balloon. When the pilot wants to descend or control the rate of descent, they can open the parachute panel. This action facilitates a rapid but controlled release of hot air, enabling the balloon to descend safely. The positioning at the top ensures that the hot air can escape efficiently and quickly, allowing for better control over the balloon's altitude.

This design feature is fundamental to hot air balloon operations, enhancing safety and maneuverability in various flying conditions. The other options do not serve the necessary function of releasing hot air effectively. For instance, a panel at the bottom would not provide the required control, nor would one in the middle or within the burner assembly be practical for this purpose.
