ED Decision 2011/012/R
The balloon at maximum mass must be capable of climbing at least 90 metres in the first minute from a start in equilibrium at ground level.
ED Decision 2011/012/R
The climb performance should be demonstrated by a test. The fully inflated balloon to maximum pressure appropriate to the conditions of the test should start from equilibrium at ground level. The climb performance should be met without excessive jettisoning of ballast.
