Question 1

VMC Airspeed Limitations

Answer 1

NOTE
All airspeed values are Indicated Airspeed (IAS), except when Calibrated Airspeed (CAS) is specifically stated.

A. At 3,000 pounds gross weight and below:
VMC Vne 130 KIAS sea level to 3,000 feet density altitude. Decrease Vne 3.5 KIAS per 1,000 feet above 3,000 feet density altitude. Maximum density altitude- 20,000 feet.

B. Above 3,000 pounds gross weight:
VMC Vne 122 Knots sea level to 3,000 feet density altitude. Decrease Vne 7.0 KIAS per 1,000 feet above 3,000 feet density altitude. Maximum density altitude- 13,500 feet.

C. Vne for internal GW above 3,200 pounds is 78 KIAS, not to exceed placarded Vne.

Question 2

Flight Restrictions for High Power

Answer 2

Vne 80 Knots with >85% to 100% Torque applied.

Question 3

Slope Landing/Takeoff Limitations

Answer 3

Slope operations shall be limited to slopes of 8 degrees or less.

CAUTION
Caution is to be exercised for slopes greater than 5 degrees since rigging, loading; terrain, and wind conditions may alter the slope landing capability.

Question 4

VFR, A+ Generator Failure- No Output

Answer 4

A. A no-output malfunction of the generator will be indicated by a zero indication on the DC Load Meter and an illumination of the MAIN GEN FAIL caution light. An attempt may be made to put the generator back on line by accomplishing the following:

    1. GEN FIELD, and GEN RESET Circuit Breakers- Check In.
    2. MAIN GEN switch- Reset then MAIN GEN. (Do not hold the switch in the RESET position.)

B. If the generator is not restored, or if it goes off line again:

    1. MAIN GEN switch- OFF
    2. Turn OFF all unnecessary electrical equipment
    3. Land as soon as PRACTICABLE.

Question 5

Flight Control Malfunctions

Answer 5

Failure of components within the flight control system may be indicated through varying degrees of feedback, binding, resistance, or sloppiness. These conditions should not be mistaken for hydraulic power failure. In the event of a flight control malfunction.

A. Land as soon as POSSIBLE.

B. Emergency Shutdown- Accomplish after landing.

Question 6

Altitude Limitations

Answer 6

A. 3,000 pounds gross weight and below:

Maximum operating -
VFR 20,000 feet pressure altitude
IFR 14,000 feet pressure altitude

B. Above 3,000 pounds gross weight:

Maximum operating -
VFR 13,500 feet pressure altitude
IFR 8,000 feet pressure altitude
