ZD576 Navigation
Come on all you RAF Helo pilots that did the NI - Scotland run, your silence on this topic is profound!
Did you not use the DME function of the Macrihanish TACAN for getting up close and personal with the Mull?
Did you get adequate performance at low level from the TACAN at the aerodrome (Ch 116 civil at present) when approaching the Mull?
Or was ch107 (the one actually selected by ZD576's TACAN CU at the time) a temporary location on higher ground specifically to aid the regular flight plan used by such flights?
It would only take one of you to have the courage to answer this and the truth would come out; not only would the pilots be rightly cleared but also the real investigation into the responsibility for this disaster could begin.
