## GM1 to Appendix 2(3.3b)) OPERATING LIMITATIONS AND EQUIPMENT REQUIREMENTS

SUPER-PRESSURE BALLOONS

Super-pressure balloons do not require flight termination devices as they quickly rise after payload discharge and burst without the need for a device or system designed to puncture the balloon envelope. In this context a super-pressure balloon is a simple non-extensible envelope capable of withstanding a differential of pressure, higher inside than out. It is inflated so that the smaller [night](https://avioverse.aero/glossary/easa/night)-time pressure of the gas still fully extends the envelope. Such a super-pressure balloon will keep essentially constant [level](https://avioverse.aero/glossary/easa/level) until too much gas diffuses out of it.
