You are flying a tail wind approach at i.e. on a 3,5 deg ILS…. That will give you close to 1000fpm, and there are also 4,0 deg glide slopes out there…
(And no, you are not doing at tailwind app to a higher deg. glideslope than normal because it is your first choice)
And also check that glide slopes coincides with the ILS… some military airports have all kind of funny papi installed, 2,25 deg , 2,5deg and so on. Some places even have two different papi set up, one left, one right of the RWY.
Popping out at minimum at night and seeing all those white papi at night does tend to make you focus at bit, even when fully briefed…
