On start-up, the throttle:
- A.
Can be fully open for the start
- B.
Can be half open for the start
- C.
Must be fully closed
- D.
Can be opened slowly to introduce fuel during the cranking of the engine
Correct Answer
C. Must be fully closedExplanation
On start-up, the throttle must be fully closed. This is because when the engine is initially started, it requires a rich fuel mixture to ignite and run smoothly. By closing the throttle, it restricts the amount of air entering the engine, allowing for a higher concentration of fuel to be delivered. This ensures that the engine receives the necessary fuel for a successful start and prevents any potential flooding or stalling of the engine.Rate this question:

What is the maximum speed for an autorotation in a Robinson R44?
- A.
100 KIAS
- B.
90 KIAS
- C.
75 KIAS
- D.
120 KIAS (Over 2200lb TOGW)
Correct Answer
A. 100 KIASExplanation
The maximum speed for an autorotation in a Robinson R44 is 100 KIAS. Autorotation is a maneuver performed by helicopter pilots in the event of an engine failure, where the rotor blades are allowed to spin freely without power. During an autorotation, the helicopter descends vertically and the pilot uses the collective and cyclic controls to control the rate of descent and the direction of the helicopter. The maximum speed of 100 KIAS ensures that the helicopter remains within safe operating limits during this maneuver.Rate this question:

What are the speeds and RRPM values when autorotating for distance?
- A.
90 KIAS and RRPM 90%
- B.
55 KIAS and RRPM 90%
- C.
100 KIAS and RRPM 90%
- D.
90 KIAS and RRPM 100%
Correct Answer
A. 90 KIAS and RRPM 90%Explanation
When autorotating for distance, the correct speeds and RRPM values are 90 KIAS (Knots Indicated Airspeed) and RRPM (Rotor Revolution Per Minute) at 90%. This means that the helicopter should maintain an airspeed of 90 knots and the rotor should be spinning at 90% of its maximum revolutions per minute. This combination of speed and rotor RPM allows for efficient autorotation, which is a technique used to safely land a helicopter in the event of an engine failure.Rate this question:

- C.
70 KIAS and 90% RRPM
- D.
55 KIAS and 100% RRPM
Correct Answer
B. 55 KIAS and 90% RRPMExplanation
For a minimum rate of descent (endurance), the aircraft needs to maintain the slowest airspeed possible while keeping the rotor revolutions per minute (RRPM) at a high enough level for stability. The correct answer of 55 KIAS and 90% RRPM satisfies these requirements by providing a slow airspeed and a high enough rotor speed to maintain stability during descent.Rate this question:

What is the normal autorotating speed for the Robinson R44?
- A.
70 KIAS
- B.
55 KIAS
- C.
60 KIAS
- D.
80 KIAS
Correct Answer
A. 70 KIASExplanation
The normal autorotating speed for the Robinson R44 is 70 KIAS. Autorotation is a maneuver performed in helicopters where the engine is disengaged and the rotor blades are allowed to rotate freely. During autorotation, maintaining a specific speed is crucial for a controlled descent and landing. In the case of the Robinson R44, the normal autorotating speed is 70 KIAS, which stands for Knots Indicated Airspeed.Rate this question:

You are cruising at 4,000' pressure altitude, 30 degrees C, 2,350lbs and 24" manifold pressure. What is the maximum KIAS?
- A.
120 KIAS
- B.
118 KIAS
- C.
100 KIAS
- D.
108 KIAS
Correct Answer
D. 108 KIASExplanation
The maximum KIAS (Knots Indicated Airspeed) is determined by the aircraft's performance and environmental factors. In this scenario, the given information includes the altitude, temperature, weight, and manifold pressure. These factors affect the aircraft's engine performance and density altitude. As the altitude and temperature increase, the density altitude also increases, resulting in a decrease in engine performance. Additionally, the weight of the aircraft affects its ability to maintain speed. Considering these factors, the maximum KIAS in this scenario is determined to be 108 KIAS.Rate this question:

- C.
9,000' Pressure Altitude
- D.
9,000' Density Altitude
Correct Answer
B. 14,000' Density AltitudeExplanation
The maximum operating altitude of the Robinson R44 Raven II is 14,000' density altitude. Density altitude is the pressure altitude corrected for non-standard temperature and humidity, and it is a more accurate measure of an aircraft's performance capabilities at higher altitudes. Therefore, the R44 Raven II can operate at a maximum altitude of 14,000' when considering the effects of temperature and humidity on its performance.Rate this question:

- B.
2,600 lbs
- C.
4700 pounds
- D.
5000 pounds
Correct Answer
C. 4700 poundsExplanation
To determine the maximum Takeoff Gross Weight (TOGW) for hovering Out of Ground Effect (OGE) at 5,500 feet pressure altitude and 30°C, we’ll follow the guidelines for helicopter performance calculations. Let’s break it down:
Hover OGE (Out of Ground Effect): This scenario involves hovering without the benefit of ground effect. We need to find the maximum weight the helicopter can handle under these conditions.
Bell 407 Example:
Takeoff Power: 100%
Pressure Altitude: 6000 feet
Outside Air Temperature (OAT): +20°C
Wind: Calm
Heater and Anti-ice: Off
Maximum Gross Weight for OGE Hover:
Refer to the table of Hover Ceiling OGE.
Enter the OAT scale at +30°C.
Move upward to the 6000 feet HP curve.
Move horizontally to the +30°C curve.
Drop down to read the maximum external gross weight of 4700 pounds.
Therefore, for hovering OGE at 5,500 feet PA and 30°C, the maximum allowable Takeoff Gross Weight (TOGW) is 4700 pounds. Keep in mind that this weight considers the density altitude and temperature conditions, ensuring safe helicopter performance during takeoff and hover.Rate this question:

Which of the following systems are inoperative with the alternator and mastery battery switches off?
- A.
Low RPM warning system
- B.
Governor
- C.
Tachometers
- D.
Hydraulics
Correct Answer(s)
A. Low RPM warning system
B. GovernorExplanation
When the alternator and mastery battery switches are turned off, the low RPM warning system and governor become inoperative. The low RPM warning system is dependent on the electrical power provided by the alternator, so when it is turned off, the system cannot function properly. The governor, which regulates the engine speed, also requires electrical power from the alternator to operate.
