But, when are you required to execute the missed approach procedure?
Wasn't the missed approach point when you hit DA on the glide slope?


It's true in general that if you start the missed approach procedure other
than at the MAP, you're not assured of obstacle/terrain clearance. But in
this case (HKS ILS 16), the missed approach procedure is consistent with and
stricter than the DP for that runway. So as long as Allen crossed the
departure threshold at 35' AGL or higher (and climbed at at least 200' per
nautical mile), he was fine.


Thank you both Mark and Gary for bringing this to my attention. My low
approach was right at 200 feet AGL (ILS minimums) over the runway, but I
never even considered obstacle clearances at the end of the runway. I
always climb out at 500 feet per minute anyway, but you both pointed out
something I never even thought of.


500FPM doesn't necessarily guarantee 200FPNM if you have a high
groundspeed.
