in post No 1 (point 2) it says ............ 'the engine stops before deployment' ......... - is that part of the standard installation / system requirement ? - the 'chute pull handle' stops the engine ?
BRS shortcomings are:
The BRS unit and mountings weigh around 30 kg. It has to be placed in the tail section (thus moving the C of G aft) and requires parts of the airframe to be strengthened to withstand the forces associated with deployment, adding another 7 Kg. Combine weight and balance considerations and at least one passenger seat has been sacrificed for the same endurance.
There is no control once the system is activated because the engine stops before deployment; and the descent speed is 25 feet per second…
The system is airspeed limited:
the aircraft must not exceed a set speed before deployment;
