With all the wiz bang gizmos in our panels these days, I went completely through the training to get an instrument ticket, and I can't remember whether this was ever addressed:
When you start timing from the final approach fix to the missed approach point, do you calculate intermediate values for the time based on groundspeed? If so, how do you do it on the fly when all that other stuff is happening?
For example flying into KCOE on the VOR RWY 5 approach my IAS is 120 knots, and the GS on my GPS says 105. The distance fromn FAF to MAP is 5.3 NM. On the gov't plate the times for 120 and 90 knots respectively are 2:39 and 3:32. If I calculate it out with a calculator (which I currently don't carry in the cockpit, I do (5.3/105)*60 = 3.03 minutes or 3:01.
What do you do? I cant imaginge trying to do the math in my head, and I don't want to get a calculator out and start crunching numbers either. I am open to suggestions.
