4A.6.18 FLIGHT IN RAIN

NOTE

Performance deteriorates in rain; this applies particularly to the take-off distance and to the maximum horizontal speed.

The effect on the flight characteristics is minimal. Flight through very heavy rain should be avoided because of the associated visibility problems.

4A.6.19 REFUELING

CAUTION

Before refueling, the airplane must be connected to electrical ground. Grounding points: exhaust, left and right. Refer to Section 2.14 for approved fuel grades.

Refueling of the Auxiliary Tanks (if installed)

CAUTION

If the auxiliary tanks are used then both tanks must be refueled to the maximum level. Only then the pilot has proper information concerning the fuel quantity in the auxiliary tanks.

If the auxiliary tanks are not in use, make sure that they are empty (refer to Section 6.4).

4A.6.20 FLIGHT AT HIGH ALTITUDE

At high altitudes the provision of oxygen for the occupants is necessary. Legal requirements for the provision of oxygen should be adhered to.

Also see Section 2.11 - OPERATING ALTITUDE.

Maximum altitude . . . . . . . . . . . . . . . . . . . . . . . .	10,000 ft pressure altitude
Minimum altitude . . . . . . . . . . . . . . . . . . . . . . . .	5,000 ft above ground level
Maximum restart airspeed . . . . . . . . . . . . . . . . .	100 KIAS or airspeed
	for a stationary propeller,
	whichever is lower

CAUTION

Do not attempt an in-flight engine restart if the engine has been shutdown for more than two minutes.

CAUTION

Do not engage the starter when the propeller is windmilling.

NOTE

At airspeeds below 100 KIAS it is possible that the propeller may windmill intermittently. Therefore, care should be taken to ensure that the propeller is stationary when engaging the starter.

NOTE

When demonstrating handling qualities with one engine inoperative the left engine is the critical engine.

Procedures

The following actions must be completed in not more than two minutes.

1.	ENGINE MASTER of selected engine	. . . . . OFF, propeller feathers
2.	POWER lever of selected engine . . . .	. . . . . IDLE
3.	Airspeed . . . . . . . . . . . . . . . . . . . . . . .	. . . . . stabilize between 90 to 100 KIAS

		stationary

CAUTION

After the engine has started, the POWER lever should be set to a moderate power setting until engine temperature have reached the green range.

4A.6.22 PRACTICE DEMONSTRATION OF VMCA

The following procedure should be completed at an altitude of at least 5,000 feet above the ground.

1.	Landing gear . . . . . . . . . . . . . . . . . . . . . . . . .	UP
2.	Flaps . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .	UP

4.	POWER lever (simulated inoperative engine)	IDLE
5.	POWER lever (other engine) . . . . . . . . . . . .	MAX (take-off power)
6.	Airspeed . . . . . . . . . . . . . . . . . . . . . . . . . . . .	reduce at approximately 1 knot
		per second until either VMCA or

NOTE

Use rudder to maintain directional control (heading) and aileron to maintain up to 5° bank towards the operative engine. At the first sign of either VMCA or stall warning initiate recovery: reduce power to IDLE on the operative engine and immediately lower the nose to regain the trim speed.
