1 . The Robinson R22 is a two place helicopter with a two bladed rotor system that has a rotor diameter of:
a ) 24 feet,
b ) 24 feet 6 inches,
c ) 25 feet,
d ) 25 feet 2 inches.
d) 25 feet 2 inches: Source: Robinson R22 Pilot Operating Handbook, Section 1 General, Page 1-3.


2 . The Robinson R22 has a Velocity Never Exceed (VNE) of:
a ) 100 Knots up to 3000 feet Density Altitude,
b ) 100 Knots up to 3000 feet Pressure Altitude,
c ) 102 Knots up to 3000 feet Density Altitude,
d ) 102 Knots up to 3000 feet Pressure Altitude.
c) 102 Knots up to 3000 feet Density Altitude: Source: Robinson R22 Pilot Operating Handbook, Limitations, Page 2-1. Every aircraft has a VNE that includes airspeed for an altitude and weight. The air density will change with the temperature of the air and the aircraft flight characteristics change also.


3 . The recommended Autorotation Airspeed for the R22 above 500 feet AGL (above ground level) is:
a ) 75 Knots,
b ) 65 Knots,
c ) 55 Knots,
d ) 50 Knots.
b) 65 Knots: Source: Robinson R22 Pilot Operating Handbook, Emergency Section, Page 3-2. Establish a steady glide at approximately 65 KIAS (Knots Indicated Airspeed).


4 . The Maximum Range Airspeed for the R22 is:
a ) 83 Knots,
b ) 85 Knots,
c ) 90 Knots,
d ) 102 Knots.
a) 83 Knots: Source: Robinson R22 Pilot Operating Handbook, Procedures Section, Page 4-1. The Maximum Range Speed gives you the best fuel economy and the most distance for the fuel available.


5 . The Hover Ceiling of the R22 is reduced by with the Carburetor Heat on by up to what altitude:
a ) 500 feet,
b ) 1000 feet,
c ) 1500 feet.
d ) 2000 feet.
d) 2000 feet: Source: Robinson R22 Pilot Operating Handbook, Performance Section, Page 5-1. Applying the Carburetor Heat decreases the air density and enriches the fuel/air mixture and decreases power.


6 . As fuel is burned in flight, the Centre of Gravity of the R22 moves:
a ) Left,
b ) Right,
c ) Forward,
d ) Aft.
c) Forward: Source: Robinson R22 Pilot Operating Handbook, Weight and Balance Section, Page 6-1. The fuel tanks are behind the Main Rotor Mast and as the fuel is burned the weight change is forward.


7 . The R22 Engine driven cooling fan (squirrel-cage) supplies cooling air to the:
a ) Engine cylinders, oil cooler, and main rotor gearbox;
b ) Engine cylinders, oil cooler, alternator and main rotor gearbox;
c ) Engine cylinders, oil cooler, hydraulics and main rotor gearbox;
d ) Engine cylinders, oil cooler, battery and main rotor gearbox.
b) Engine cylinders, oil cooler, alternator and main rotor gearbox: Source: Robinson R22 Pilot Operating Handbook, System Description Section, Page 7-3. The Engine cylinders have fins on where the heat is taken away by the airflow, the oil cooler is a small radiator that has cooling air flowing through it to remove heat, the alternator and main rotor gearboxes have hoses running to them for airflow. The Robinson R44 also has the battery, hydraulics and magnetos cooled by the cooling air system.


8 . When draining fuels during a pre-flight inspection the recommended amount of fuel to be drained is:
a ) Enough fuel to remove any water or dirt and check for the approved fuel colour,
b ) Enough fuel to remove any water or dirt and check for the approved fuel colour, and no less than ¼ litre (quart),
c ) Just enough to get some in the fuel container so you know you have fuel in the tanks,
d ) A fuel drain is not required because of the very good quality control for Aviation Fuels.
a)) Enough fuel to remove any water or dirt and check for the approved fuel colour: Source: Robinson R22 Pilot Operating Handbook, Handling and Maintenance Section, Page8-8. You need to be able to see that there is no water (which will form round beads when in small amounts) or dirt, and to ensure that the colour of the fuel is correct, 100LL Avgas has a clear blue colour.


9 . Information for using any equipment that is installed on the aircraft that is not standard equipment from the Robinson Factory can be found where:
a ) On the manufacturers website with all the information for using it on your aircraft,
b ) In your Company Operations Manual in the Training Section for New Equipment,
c ) On the Robinson Helicopter Company Website under Customer Support,
d ) In the Supplement Section of the Robinson R22 Pilot Operating Handbook.
d) Supplement Section #9 of your Robinson R22 Pilot Operating Handbook: All supplementary equipment needs to have information available to the pilot so they can refer to it for: Limitations, Operations, Weight and Balance and any other pertinent information.


1 0 .The Robinson Helicopter Company has been following accidents and incidents in the helicopter industry, especially with their own helicopters and has given every pilot access to their recommendations for flying their helicopters more safely. This information is found where.
a ) Robinson Helicopter Website under Safety Notices,
b ) Robinson R22 Pilot Operating Handbook,
c ) Mail out subscription as new information is available,
d ) All the above.
