When can aileron trim not be used#
with the autopilot engaged
44
Autopilot engagement height#
250 feet after takeoff
45
Autopilot dis-engagement height#
Without LAND 2 or LAND 3 annunciated, the autopilot must not remain engaged below 100 feet RA. The autopilot must be disengaged before the airplane descends more than 50 feet below minimums unless it is coupled to an ILS glideslope and localizer or in the go-around mode.
46
Autoland wind speed limitations#
HW/XW:25 | TW/XW cat2,3:15
47
Autoland GS angles#
``` # The maximum glideslope angle is 3.25 degrees. # The minimum glideslope angle is 2.5 degrees. ```
48
Autoland flap settings#
Automatic landings may be made with flaps 25 or 30 only.
49
FLCH limitation#
Do not use FLCH on final approach below 1,000 feet AFE.
50
VHF Frequency Limitation on | N409MC, N476MC, N480MC, N496MC-N499MC
Do not use the center VHF radio on 120.000 MHz or 120.005 MHz as the required means of communication.
51
ATC clearance data received through the FMC which can only be viewed on the flight deck printer, limitations?
must be independently verified with the originating ground | station.
52
Continuous ignition must be ON encountering?
``` • heavy rain • severe turbulence • volcanic ash • icing conditions • standing water or slush on runway Note: Continuous ignition is automatically provided when nacelle anti-ice is on. ```
53
Reverse Thrust limitations#
``` # Intentional selection of reverse thrust in flight is prohibited. # Backing the airplane with use of reverse thrust is prohibited ```
54
APU start cycle restrictions are:
1, 1, 75 mins
55
Flight Control Limitations?#
``` # Avoid rapid and large alternating control inputs, especially in combination with large changes in pitch, roll, or yaw (e.g., large side slip angles) as they may result in structural failure at any speed, including below VA. ```
56
The maximum altitude with flaps extended is
20,000 feet.
57
Use of speedbrakes in flight with flaps extended past...
20 is not recommended
58
IFR approach procedures using VNAV to a DA(H) are not authorized if the path angle is?
less than 2.75 or more than 3.50 degrees
59
After changing altimeter setting from QNE to QNH, or QNH to QNE with respect to VNAV, limitiations?#
``` # 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. ```
60
The maximum tank fuel temperature is
+54 degrees C.
61
In-flight tank fuel temperature must be maintained
at least 3° C above the fuel freezing point of the fuel being used. The use of Fuel System Icing Inhibitor additives does not change the minimum fuel tank temperature limit. Do not cycle CWT and HST pump switches from ON to OFF to ON with
62
Which fuels are prohibited
The use of Jet B and JP4
