C240
So they stopped engines after moving to the terminal? Fuel critical flight, I think it was. Interesting.
Sycamore good stuff – I made the point a long time ago that there was not the right effort put into a rational analysis of the nav data, especially (as you too infer) that the nature of the crash could be navigation related; I go further and say why wasn't the CPLS acknowledged when its (mis) use explains their actions and the crash.
You mention waypoint “H” - if you go back some time in the posts, you'll find I had put in a link to a map with suggested a/c tracks on it – basically, I believe that Aldergrove to H then B gave a clear, safe LL route, handrailing up the coast of Islay/Jura – I suspect that H had been A but the Mull was added later (an excursion) with the intent to return to that safe route after Mull (H to B was 028 mag and the navigators HoSI was found with 028 on its course setting). H was simply an available letter after those used for Inverness.
