1. The Robinson R44 is a four place helicopter with a two bladed rotor system that has a rotor diameter of:
a) 34 feet,
b) 34 feet 6 inches,
c) 33 feet,
d) 33 feet 4 inches.
c) 33 feet: Source: Robinson R44 Pilot Operating Handbook, Section 1 General, Page 1-3.
2. The Robinson R44 with a Weight below 2200 pounds has a Velocity Never Exceed Airspeed (VNE) of:
a) 130 Knots up to 3000 feet Density Altitude,
b) 130 Knots up to 3000 feet Pressure Altitude,
c) 120 Knots up to 3000 feet Density Altitude,
d) 120 Knots up to 3000 feet Pressure Altitude.
a) 130 Knots up to 3000 feet Density Altitude: Source: Robinson R44 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 R44 above 500 feet AGL (above ground level) is:
a) 70 Knots,
b) 65 Knots,
c) 60 Knots,
d) 55 Knots.
70 Knots: Source: Robinson R44 Pilot Operating Handbook, Emergency Section, Page 3-2. Establish a steady glide at approximately 70 KIAS (Knots Indicated Airspeed).
4. The Maximum Range Airspeed for the R44 is:
a) 83 Knots,
b) 85 Knots,
c) 90 Knots,
d) 100 Knots.
d) 100 Knots: Source: Robinson R44 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 R44 Astro and Raven is reduced with the Carburetor Heat on by up to what altitude:
a) 1000 feet,
b) 1600 feet,
c) 2000 feet,
d) 2400 feet.
d) 2400 feet: Source: Robinson R44 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. The R44 II does not use carburetor heat because the carburetor is Replaced with a fuel injection system. The fuel is delivered directly to the intake valve of the cylinder where it is drawn in reducing the need for any heating.
6. As fuel is burned in flight, the Centre of Gravity of the R44 moves:
a) Left and aft,
b) Right and forward,
c) Forward and left,
d) Aft and right.
b) Right and forward: Source: Robinson R44 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. The main tank is larger (almost double the capacity of the auxiliary tank) and on the left of the helicopter, so when the fuel has been drawn down to ¼ or less in the main tank, the left auxiliary tank is empty so the Centre of Gravity will move right as well as forward.
7. The R44 Engine driven cooling fan (squirrel-cage) supplies cooling air to the:
a) Engine cylinders, oil cooler, and main rotor gearbox, main cabin,
b) Engine cylinders, oil cooler, alternator and main rotor gearbox, tail rotor gearbox, starter,
c) Engine cylinders, oil cooler, hydraulics and main rotor gearbox,
d) Engine cylinders, oil cooler, battery and main rotor gearbox, alternator, magnetos, hydraulics (if installed).
d) Engine cylinders, oil cooler, battery, main rotor gearbox, alternator, magnetos, hydraulics: Source: Robinson R44 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, main rotor gearboxes, hydraulics, magnetos, battery and alternator 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 the R44 Raven II fuel during a pre-flight inspection the recommended procedure is:
a) Boost pump on and drain the gascolator only, check for water, dirt and the approved fuel color,
b) Boost pump off, drain fuel to remove any water or dirt and check for the approved fuel color, and no less than ¼ litre(quart),
c) Drain the fuel tanks and gascolator with enough fuel to remove any water or dirt, check the color and clarity of the fuel,
d) A fuel drain is not required because of the very good quality control for Aviation Fuels and the R44 II boost pump will keep the fuel flowing.
c) Enough fuel to remove any water or dirt and check for the approved fuel colour: Source: Robinson R44 Pilot Operating Handbook, Handling and Maintenance Section, Page 8-9. 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 color of the fuel is correct, 100LL Avgas has a clear blue colour. This should be clear with no particles.
9. Equipment that has been installed on the aircraft that is not provided by Robinson Helicopter can include:
a) Cargo Hook,
c) Cargo Mirrors,
d) All the above.
d)Supplement Section: 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. This equipment can be found through various helicopter equipment providers.
10. The Robinson Helicopter Company Pilot Operating Handbook has a Canadian Supplement for helicopters that work and are registered in Canada. This supplement has temperature limitations of:
a) +45°C to -45°C,
b) +35°C to -35°C,
c) +39°C to -40°C,
d) +40°C to -40°C.
