For those of you using handheld GPS's when you fly IFR:

Do you use the throttle to increase/decrease power to match the ground
speed to the approach speed table so the time is correct to the MAP?

No sir. That could, or is a very dangerous practice.
You compute the time to the MAP based on the Gs while flying your
normal airspeed on approach.


Or,

Do you use the distance to the airport to determine/verify the MAP, even
though the time may not have expired?

I use it along with the RNAV computer to give time and distance for
situational awareness.

If I did everything right the time expires when I reach the MAP (or
close to it)
