Some operators require:
1000 feet: Stable on instrument approach(s)
500 feet: Stable on visual approach
Land in touchdown zone
Stable criteria:
In general (varies from operator to operator) +10/-5 knots VREF speed and no more than FOM quoted ILS glide slope and LOC deflections, along with VNAV lateral and vertical approach tolerances for example.
Visual approach: No more than the speed variance above and no greater than 1000 FPM descent rate, unless corrections are made to be within limits at the 500 feet gate height.
If you aren't going to be stable or land in the touchdown zone, then a GA will be carried out and either pilot can call "Go around".
Seems straight forward, but I am surprised to see different performances during simulator training and the inability of PM to call "GA". In the real world, situations like this occur to experienced crews for one thing or another but typically fatigue or inexperience is also the issue.
