20
Q

Is aerobatic flight allowed in the R22?

A

No

21
Q

What type of maneuvers are prohibited?

A

Low-G cyclic pushovers which can cause a catastrophic loss of lateral control.

22
Q

How do you eliminate a low-G condition?

A
  • immediately apply gentle aft cyclic.

- Should a right roll commence apply aft cyclic to reload rotor before applying lateral cyclic to stop the roll.

23
Q

When is flight with the governor off allowed?

A

In-flight system malfunction or emergency procedures training.

24
Q

What is the maximum operating density altitude?

A

14,000’

25
Q

What is the capacity of the fuel tanks?

A

16.9 gallons in the main, 9.4 gallons in the aux for a total of 26.3 gallons.

26
Q

What are the flight restrictions with regard to wind for a pilot with less than 200 hrs in helicopters and 50 hrs in the R22?

A
  1. Flight when surface winds exceed 25 kts.
  2. Flight when surface wind gust spreads exceed 15 kts.
  3. Continued flight in moderate, severe, or extreme turbulunce.
27
Q

What should airspeed be adjusted to when encountering moderate, severe, or extreme turbulence?

A

60 KIAS and 0.7 Vne (72 KIAS) and no lower than 57 KIAS.

28
Q

What is moderate turbulence?

A

Turbulence that causes:

1) changes in altitude and attitude
2) variations in indicated airspeed
3) aircraft occupants to feel definite strains against seat belts.

29
Q

What type of rotor system does the R22 have?

A

Semi-rigid underslung rotor system that is free to tilt with respect to the main the rotor shaft on what is known as a teetering hinge.

30
Q

What does the teetering hinge do?

A

Allows the blades to flap together as a unit. As one blade flaps up the other flaps down.

31
Q

What does air cooled mean?

A

No water is used to cool the engine. No radiator.
