4B.10.5 FLASHING YELLOW MODE ANNUNCIATION

NOTE

Abnormal mode transitions (those not initiated by the pilot or by normal sequencing of the autopilot) will be annunciated by flashing the disengaged mode in yellow on the PFD. Upon loss of a selected mode, the system will revert to the default mode for the affected axis, either ROL or PIT. After 10 seconds, the new mode (PIT or ROL) will be annunciated in green.

Loss of Selected Vertical Mode (FLC, VS, ALT, GS)

1. Autopilot mode controls . . . . . . . . . . . . . . . . . . select another vertical mode

If on an instrument approach:

2. Autopilot . . . . . . . . . . . . . . . . . . . . . . . . . . . . . DISCONNECT and continue manually or execute missed approach

Loss of Selected Lateral Mode (HDG, NAV, GPS, LOC, VAPP, BC):

1. Autopilot mode controls . . . . . . . . . . . . . . . . . . select another lateral mode

If on an instrument approach:

2. Autopilot . . . . . . . . . . . . . . . . . . . . . . . . . . . . .	DISCONNECT and continue
	manually or execute missed
	approach

4B.10.6 EFFECTS OF G1000 LOSSES UPON AUTOPILOT OPERATION

G 1000 System Loss	Effect upon Autopilot Operation
AHRS	The autopilot disconnects and autopilot, yaw damper
	and flight director are inoperative. Manual electric trim is
	available.
HDG function of AHRS	The autopilot will remain engaged with the loss of the
	HDG Mode.
MFD	The autopilot will remain engaged with limited
	functionality.

	director are inoperative. Manual electric trim is available.
GIA No. 1	The autopilot disconnects and autopilot, flight director
	and manual electric trim are inoperative.
GIA No. 2	The autopilot disconnects and autopilot and manual
	electric trim are inoperative. Flight director is available.
GPS No. 1 and 2	The autopilot and flight director operates in NAV modes
	only (LOC, BC, VOR, VAPP) with reduced accuracy.

Procedures

4B.11 LANDING WITH HIGH LANDING MASS

CAUTION

Damage of the landing gear can result from a hard landing with a flight mass above the maximum landing mass.

NOTE

A landing with a mass between 1805 kg (3979 lb) and 1900 kg (4189 lb) is admissible. It constitutes an abnormal operating procedure. A "Hard Landing Check" is only required after a hard landing, regardless of the actual landing mass.

Perform landing approach according to Section 4A.6.11.

Procedures

4B.12 L/R AUX FUEL TRANSFER FAIL (IF AUX. TANKS ARE INSTALLED)

If the fuel quantity in a main tank does not increase during fuel transfer:

1.Switch OFF both AUX PUMPS.

2.Check fuel pump LH/RH OFF.

CAUTION

An imbalance in the auxiliary tanks is approved when the imbalance in the main tanks is less than 1 US gal (3.8 liters).

2.Check fuel imbalance in the main tanks; use CROSSFEED function to keep the LH and RH main tank imbalance within the permissible limit of 1 US gal

(3.8 liters).

3.Switch the remaining AUX PUMP ON.

4.Use crossfeed function to keep the LH and RH main tank imbalance within the permissible limit of 1 US gal (3.8 liters).
