3.25 Degrees
Minimum glideslope angle for auto land operations
2.5 Degrees
Reverse thrust limitations
1) Intentional select of reverse thrust during flight is prohibited.
2) Backing the airplane with the use of reverse thrust is prohibited.
VNAV limitation concerning transition level/altitude
If leveling off within 2000ft after changing altimeter setting from QNE to QNH, or vice versa, do not use VNAV to execute the level-off if QNH is less than 29.70/1006hPa. After the level-off is complete, VNAV may be re-engaged.
