Abnormal Operating

Procedures

4B.4.7 L/R COOL LVL

L/R COOL LVL

Left / Right engine coolant level is low.

A low coolant caution alert may indicate a loss of coolant. This will subsequently lead to decreased engine cooling capability / loss of engine power due to engine failure.

1. Annunciations / Engine instruments . . . . . . . monitor

See 4B.3.2 - COOLANT TEMPERATURE.

NOTE

The indication is calibrated for straight and level flight. The caution message may be triggered during turns which are flown with slip, or while taxiing in curves.

Procedures

4B.4.8 PITOT FAIL / HT OFF

PITOT FAIL	Pitot heating system has failed.
PITOT HT OFF	Pitot heating system is OFF.
1. PITOT HEAT . . . . . .	. . . . . . . . . . . . . . . . . . . check ON / as required

NOTE

The Pitot heating caution message is displayed when the Pitot heating is switched OFF, or when there is a failure of the Pitot heating system. Prolonged operation of the Pitot heating on the ground can also cause the Pitot heating caution message to be displayed. In this case it indicates the activation of the thermal switch, which prevents overheating of the Pitot heating system on the ground. This is a normal function of the system. After a cooling period, the heating system will be switched on again automatically.

If in icing conditions:

2.Expect loss of static instruments.

3.Leave icing zone / refer to 3.11.4 - UNINTENTIONAL FLIGHT INTO ICING.

Procedures

4B.4.9 STALL HT FAIL / OFF

STAL HT FAIL	Stall warning heat has failed.
STAL HT OFF	Stall warning heat is OFF.
1. PITOT HEAT . . . . .	. . . . . . . . . . . . . . . . . . . check ON / as required

NOTE

The STAL HT OFF caution message is displayed when the

Pitot heating is switched OFF, or STAL HT FAIL when there is a failure of the stall warning heating system. Operation of the stall warning heating on the ground also causes the stall warning heating failed caution message to be displayed. In this case it indicates the activation of the thermal protection relay, which prevents overheating of the stall warning heating system on the ground. This is a normal function of the system.

If in icing conditions:

2.Expect loss of acoustic stall warning.

3.Leave icing zone / refer to 3.11.4 - UNINTENTIONAL FLIGHT INTO ICING.

4B.4.10 L/R AUXILIARY FUEL TANK EMPTY (if installed)

L/R AUX FUEL E	Left / Right auxiliary fuel tank empty (displayed only
	when AUX PUMP switch is ON).

The auxiliary tank empty caution message indicates an empty auxiliary fuel tank while the aux. fuel pump is switched ON.

Abnormal Operating

Procedures

4B.4.11 STICK LIMIT

STICK LIMIT	Control stick limiting system (variable elevator stop) has
	failed.

The variable elevator backstop is activated depending on the position of the power levers. The system has two failure modes which can be identified as follows:

(a)Both power levers are in a position for a power setting of more than approximately

20 % LOAD:

CAUTION

The variable elevator backstop is inoperative. In case of stalling with "power-on" the handling qualities and stallcharacteristics are degraded significantly. Do not stall the airplane in any configuration.

(b)At least one power lever is in a position for a power setting of less than approximately 20 % LOAD:

CAUTION

The variable elevator backstop is active all the time, reducing the maximum elevator "pull"-deflection. This results in reduced elevator capacity. In this case it is important not to reduce airspeed below required minimum vREF = 84 KIAS during the approach for landing, especially at loading conditions with forward locations of the center of gravity (see Section 4B.11).

CHECK GEAR

Landing gear is not down and locked.
