VNAV Path Descent after the TOD on the 737-400
I like to know what the VNAV path descent is based on and how the TOD point is calculated.
Is it based on a 3 degree descent angle?
If so, is it not uncommon for the engines to be applying significant power (50 + percent N1) on a VNAV path descent to hold that 3 degree angle and appropriate selected descent speed?
Not a 37 driver, but I've always thought at the TOD the throttles go all the way to idle.
Cheers.
