DDS:
Have you seen where the Start Master Switch is?
Yes, and I am looking at it right now. According to the Human Factors Report, associated with the XV249 investigation, the probability of inadvertent operation (being left open after engine start, or being knocked in flight) was set at "probable" (Will occur several times in life of item). A red line entry does not guarantee anything.
This is not my judgement, it is the judgement of the RAF Centre of Aviation Medicine.
