As said offcourse you add thrust, but thats only because you haven't been paying attention for a considerable amount of time during which you haven't been meeting the performance requirement for the last few seconds due to lack of thrust.
At 2000 feet i'm doing 160kts usually not anywhere near being low on my approach speed.
i'm talking about stabilized approaches as taught in the FCTM, not rescueing massive ****ups in this area.
