hazard to the aeroplane, its occupant(s) or ground personnel whilst the system is not
deployed; and that when properly maintained, the risk of malfunction, deterioration or
inadvertent deployment is minimised. The BMAA has not approved the system itself or
considered the circumstances, if any, in which it might be deployed. The effectiveness
of the system for the safe recovery of the aeroplane has not been demonstrated.
