We operate into a couple of airfields where the TCH (threshold crossing height) is negative on an ILS !!
Wow that's a new one to me, I take it the ILS is stationed offset in a gully or something? Anyway, if your company SOP was for the PM to remain on the clocks until DA, that would be a pretty comfortable exercise, if your company SOP was to be on them until TCH then no wonder pilots are looking out the window
my point being that you most likely have a company briefing on those airports and that won't include being on instruments until TCH as that would be silly. If it has the PM on instruments only until DA, no problem.
I'm now off to google Bardufoss, sounds cool.
