CAT I GA 5.0% approaches and the go around

Hi,

I've always been wondering what would happen if the aircraft became unstable and had to go around after the minimums in a (for example) CAT I GA 5.0% approach. Because if you fly the 5.0% it reckons you go around at minimums as the latest altitude, and from there make it over the terrain, right? So what would happen if you would for example float over the TDZ and HAVE to go around? Is it just TOO late, or is it still possible to be assured terrain clearance?

The missed approach gradient is usually limiting with one engine inoperative, so before making the approach you should calculate, that if engine fails during approach and you initiate the go-around at DA/MDA, you will be able to maintain at least 5.0% (in this case).

If you have to go-around below DA/MDA, then it is a bit of a grey area. Generally, you would only do this with all engines operating, but if an engine fails durugin go-around from below DA/MDA, then it would be sensible to follow the EOSID (engine-out SID) for that runway or any other routing, that would clear you of obstacles.

All right, that makes sense.
Thanks for the response!
