Why wouldn't they demonstrate the new kit for fast insertion/extraction, etc in bad conditions by setting something up using a CPLS in that useful area of fixed/localised predictable weather on the Mull?
Walter, why do you repeatedly choose to ignore the most obvious of answers already given in response to your questions? I repeat, these passengers would have
no operational or technical interest in a homing system. As long as their tasks involving helicopters were successfully completed, it would be of no benefit for them to know in detail how a landing site was found by the crew. In any event, even if they had any passing interest, they would not be able to see what was going on in the cockpit and such a demonstration would be impractical.
Again, I say to you (this must be at least the third time)
if the purpose of the flight
was to demonstrate a homing device fitted to this particular Mk2 airframe, how on earth does this
possibly fit in with the captain's request for a completely different airframe, a Mk1?
