HW/XW:25

TW/XW cat2,3:15

47
Q

Autoland GS angles#

A 
# The maximum glideslope angle is 3.25 degrees.
# The minimum glideslope angle is 2.5 degrees.
48
Q

Autoland flap settings#

A

Automatic landings may be made with flaps 25 or 30 only.

49
Q

FLCH limitation#

A

Do not use FLCH on final approach below 1,000 feet AFE.

50
Q

VHF Frequency Limitation on

N409MC, N476MC, N480MC, N496MC-N499MC

A

Do not use the center VHF radio on 120.000 MHz or 120.005 MHz as the required
means of communication.

51
Q

ATC clearance data received through the FMC which can only be viewed on the
flight deck printer, limitations?

A

must be independently verified with the originating ground

station.

52
Q

Continuous ignition must be ON encountering?

A 
• 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
Q

Reverse Thrust limitations#

A 
# Intentional selection of reverse thrust in flight is prohibited.
# Backing the airplane with use of reverse thrust is prohibited

1, 1, 75 mins

55
Q

Flight Control Limitations?#

A 
# 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
Q

The maximum altitude with flaps extended is

A

20,000 feet.

57
Q

Use of speedbrakes in flight with flaps extended past…

A

20 is not recommended

58
Q

IFR approach procedures using VNAV to a DA(H) are not authorized if the path
angle is?

A

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?#

A 
# 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
Q

The maximum tank fuel temperature is

+54 degrees C.

61
Q

In-flight tank fuel temperature must be maintained

A

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
