Exrigger: Many thanks for that information. I have read the Hansard statement many times, and it is clear that the spokesman states that Nimrod carries PVC/Nylon wiring not Kapton. My feeling is that although that was the case when Nimrod entered service, Kapton wiring has been used for additional equipment fits such as Yellowgate. My basic question simply begs a yes/no answer from avionics at 1st line.
By the way, I note from your 2nd reference that whilst Kapton wiring is considered to be very dangerous, PVC/Nylon is regarded as dangerous and is subject to aging and has a low operating temperature. It is not used by the USAF
