Explanation

The longitudinal mass balance is used to help neutralize the effect of acceleration on the control stick during maneuvers in an F-15 aircraft. This component helps to counteract the forces experienced by the pilot when the aircraft accelerates or decelerates, ensuring that the control stick remains stable and easy to manipulate. By incorporating a mass balance system, the F-15 can maintain control and stability throughout various maneuvers, improving the overall performance of the aircraft.

Which F-15 longitudinal flight control subsystem component has built-in centering springs which resist stick movement giving the pilot a stick feel force?
- PITCH RATIO switch.
- Pitch ratio controller.
- Longitudinal mass balance.
- Longitudinal feel trim actuator (LFTA).
Correct Answer

A. Longitudinal feel trim actuator (LFTA).

Explanation

The correct answer is the Longitudinal feel trim actuator (LFTA). This component has built-in centering springs that resist stick movement, providing the pilot with a stick feel force. This allows the pilot to have a better sense of control and feedback when maneuvering the aircraft in pitch. The other options mentioned, such as the PITCH RATIO switch, Pitch ratio controller, and Longitudinal mass balance, do not have the same function of providing stick feel force to the pilot.

Which F-15 longitudinal flight control subsystem component contains an airspeed scheduling valve, a Mach factor computer, and an aileron rudder interconnect (ARI) Mach valve?
- PITCH RATIO switch.
- Pitch ratio controller.
- Longitudinal mass balance.
- Longitudinal feel trim actuator (FTA).
Correct Answer

A. Pitch ratio controller.

Explanation

The correct answer is the Pitch ratio controller. The Pitch ratio controller is a component of the F-15 longitudinal flight control subsystem. It contains an airspeed scheduling valve, a Mach factor computer, and an aileron rudder interconnect (ARI) Mach valve. This controller is responsible for adjusting the pitch ratio of the aircraft based on its speed and Mach number, ensuring proper control and stability during flight.

Which F-15 longitudinal flight control subsystem component automatically compensates for trim changes caused by accelerating from subsonic to supersonic flight?
- Mechanical mixer.
- Pitch trim controller (PTC).
- Pitch ratio controller (PRC).
- Longitudinal feel trim actuator (FTA).
Correct Answer

A. Pitch trim controller (PTC).

Explanation

The Pitch Trim Controller (PTC) is the correct answer because it automatically compensates for trim changes caused by accelerating from subsonic to supersonic flight. It adjusts the pitch trim to maintain the desired aircraft attitude and stability during this transition. The other options, such as the Mechanical Mixer, Pitch Ratio Controller (PRC), and Longitudinal Feel Trim Actuator (FTA), do not specifically address the compensation for trim changes in this specific flight scenario.

Which F-15 directional flight control subsystem component contains centering springs, providing an artificial feel used to keep the rudder pedals centered?
- Rudder actuator.
- Rudder limiter actuator.
- Directional feel trim actuator.
- Directional control breakout assembly.
Correct Answer

A. Directional feel trim actuator.

Explanation

The directional feel trim actuator contains centering springs that provide an artificial feel to keep the rudder pedals centered. This means that when the pilot releases pressure on the rudder pedals, the centering springs will automatically return the pedals to their neutral position. This helps the pilot maintain control and stability during flight. The other options, such as the rudder actuator, rudder limiter actuator, and directional control breakout assembly, do not specifically mention centering springs or the function of keeping the rudder pedals centered. Therefore, the correct answer is the directional feel trim actuator.

Rate this question:
48.

Which F-15 directional flight control subsystem component transmits the input force from the aileron rudder interconnect (ARI) into two separate push-pull cables?
- Rudder actuator.
- Rudder limiter actuator.
- C. Directional feel trim actuator.
- Rudder control breakout assembly.
Correct Answer

A. Rudder control breakout assembly.

Explanation

The correct answer is the Rudder control breakout assembly. This component is responsible for transmitting the input force from the aileron rudder interconnect (ARI) into two separate push-pull cables. It serves as a connection point between the ARI and the cables, allowing for the control and movement of the rudder. The other options, such as the rudder actuator, rudder limiter actuator, and directional feel trim actuator, are not specifically designed to perform this function.

Rate this question:
49.

The F-15 rudder limiter actuator is used to prevent commanded excessive rudder travel when the aircraft is traveling above what Mach?
- 1.
- 2.
- 1.5.
- 2.5.
Correct Answer

A. 1.5.

Explanation

The F-15 rudder limiter actuator is used to prevent excessive rudder travel when the aircraft is traveling above Mach 1.5. This is necessary because at high speeds, the rudder can generate excessive forces that may put stress on the aircraft's structure and potentially cause damage. By limiting the rudder travel, the actuator helps to ensure the safe operation of the aircraft at high speeds.
