• ED Decision 2011/012/R found in: CS-31GB Initial issue - Free Gas Balloons (Dec 2011)

AMC 31GB.14(b) Minimum mass ED Decision 2011/012/R Minimum mass. The determination of the minimum mass should take into consideration that the controllability of the balloon might be affected by a low internal pressure at low mass. At least the following should be demonstrated: In landing configuration with minimum crew, untaut condition and already disposed minimum ballast, all controls (e.g. parachute, valve, rip panel, control lines, etc.) should have a positive performance and function easily and smoothly. Note: An untaut condition is a flight with a ‘slack’ envelope and open appendix.
