Which feature at the top of the envelope allows deflation by releasing gas?

• A. Crown
• B. Gondola
• C. Gore
• D. Parachute panel

Answer: (D)

The mechanism that allows a canopy to deflate by releasing gas is a vent at the top of the canopy, in the crown region. The crown is the highest point of the canopy where the lines meet, and it often houses a vent that lets air escape. By releasing gas from this top vent, internal pressure drops and the canopy can collapse or settle more smoothly, helping prevent over-inflation and improving stability during descent. Gore refers to the individual fabric panels that shape the canopy, not a vent. A parachute panel is a generic term for any section of fabric, without implying a vent at the top. A gondola is unrelated to the canopy itself. So the ability to deflate by releasing gas is tied to venting at the crown, the topmost part of the envelope.
