VNAV Selection Limitation B744
"If leveling off within 2000 feet after changing altimeter setting from QNE to
QNH, or QNH to QNE, do not use VNAV to execute the level-off if QNH is less
than 29.70 in/1006 hPa. After the level-off is complete, VNAV may be
re-engaged."
Anyone know the results if this is not followed? Overshoot the level off?
Thanks
