Approaching airports with terrain around I usually get terrain cautions and warnings while operating well within the approach area.

Real aircraft have a protection zone around the approach where the warning is supressed (no, that's not in any FCOM so don't ask for an AIIR here, just ask yourself why on no video of an approach to Madeira, etc. you will not hear any terrain warnings while yours goes crazy).

This is especially important on airports with circling approaches, etc. where yours will always go crazy with its terrain, pull up and what not warnings.
Examples would be, amongst others, LPMA, GCLA, LDDU, LDSP, LGSM, LGKO, LTBS and anything mountanious.

Bug exists on both, 757 and 767.
