Approach button

Asked by: 2819 views General Aviation

What will happen if I hit Approach Button during VOR, NDB approach (green needle)? Will it descend in VNAV mode? Or just stay level?  And what about during LNAV approach (blue needle)?

    What do the manuals and POH (specifically including the equipment POH Supplements) for your specific GPS, autopilot and aircraft say?
