Hi Cleo,
Well, that's why you check your Approach Climb limiting mass with F15 before you go anywhere near the runway - right?
If you go-around and then loose an engine, you will still fly F15, and the aircraft will climb away nicely at top bug.
If you for some reason are limited not by max. landing mass vs. LDA, but by Approach climb limiting mass, you might find that you can increase your allowable landing mass by using F15 for landing. In that case, the max. mass vs. LDA will drop, but your max. mass vs. approach climb will increase. However, I fail to see how F15 will help you land on a short or contaminated runway?
Best regards,
