Aviation Engine Start and Flight Management Quiz: Mastering Procedures and Indications

1. During engine start, what does the "IGN" message on the FMA signify?

Ignition system has failed.

Ignition system is deactivated for engine shutdown.

Ignition system is activated for engine start.

Ignition system is active for APU start.

The "IGN" message on the FMA signifies that the ignition system is activated for engine start. This means that the ignition system is providing the necessary spark to ignite the fuel-air mixture in the engine, allowing it to start running.

Explanation

The "IGN" message on the FMA signifies that the ignition system is activated for engine start. This means that the ignition system is providing the necessary spark to ignite the fuel-air mixture in the engine, allowing it to start running.

2. The thrust limit is computed by:

The FMGC according to the AP/FD mode.

The ECU according to the thrust lever position.

The ECU according to the AP/FD mode.

The FMGC according to the ECU order.

The thrust limit is computed by the ECU (Engine Control Unit) according to the thrust lever position. The ECU determines the appropriate thrust limit based on the position of the thrust lever, which is controlled by the pilot. This allows the pilot to manually adjust the thrust output of the engine based on the desired power setting.

Explanation

The thrust limit is computed by the ECU (Engine Control Unit) according to the thrust lever position. The ECU determines the appropriate thrust limit based on the position of the thrust lever, which is controlled by the pilot. This allows the pilot to manually adjust the thrust output of the engine based on the desired power setting.

3. The "THR LVR" message displayed on the FMA indicates:

Throttle levers are in the climb position.

Thrust levers are not set to the required takeoff thrust.

Thrust levers are set for approach and landing.

Throttle levers are not in the idle position.

The "THR LVR" message displayed on the FMA indicates that the throttle levers are in the climb position.

Explanation

The "THR LVR" message displayed on the FMA indicates that the throttle levers are in the climb position.

4. If the "REV" message appears on the FMA during the takeoff phase, it means:

Reversers are not stowed properly.

Reverse thrust is prohibited in this phase of flight.

Thrust reversers are deployed.

Reverse thrust is selected.

If the "REV" message appears on the FMA during the takeoff phase, it means that reverse thrust is selected. This indicates that the pilot has activated the thrust reversers, which are used to help slow down the aircraft after landing. However, during takeoff, reverse thrust should not be selected, as it can cause a loss of control and is prohibited in this phase of flight. Therefore, if the "REV" message appears, it suggests that the pilot has mistakenly selected reverse thrust during takeoff.

Explanation

If the "REV" message appears on the FMA during the takeoff phase, it means that reverse thrust is selected. This indicates that the pilot has activated the thrust reversers, which are used to help slow down the aircraft after landing. However, during takeoff, reverse thrust should not be selected, as it can cause a loss of control and is prohibited in this phase of flight. Therefore, if the "REV" message appears, it suggests that the pilot has mistakenly selected reverse thrust during takeoff.

5. On ground the automatic start sequence is:

Start valve opens, ignition starts when N2 > 16% when N2 > 50% start valve closes and igniter off.

Start valve and HP fuel open when N2 > 22%, start valve closes when N2 > 50%.

The correct answer explains the sequence of events that occur during the automatic start of an engine. It states that the start valve and LP fuel valve open first, followed by the ignition starting when the N2 (rotor speed) is greater than 16%. Then, the HP fuel valves open when the N2 is greater than 22%, and when the N2 is greater than 50%, the start valve closes and the igniter turns off. This sequence ensures the proper flow of fuel and ignition to start the engine efficiently.

Explanation

The correct answer explains the sequence of events that occur during the automatic start of an engine. It states that the start valve and LP fuel valve open first, followed by the ignition starting when the N2 (rotor speed) is greater than 16%. Then, the HP fuel valves open when the N2 is greater than 22%, and when the N2 is greater than 50%, the start valve closes and the igniter turns off. This sequence ensures the proper flow of fuel and ignition to start the engine efficiently.

6. "LVR CLB" flashes white on FMA, if the throttles are not in CL position when:

The A/C is at lift-off.

The landing gear is retracted.

When the aircraft is on the ground and the throttles are set to the climb detent position.

The A/C is above the altitude of thrust reduction.

When "LVR CLB" flashes white on the Flight Mode Annunciator (FMA), it indicates that the aircraft is above the altitude of thrust reduction. This means that the throttles should be in the climb (CL) position at this altitude, but they are not. The FMA is alerting the pilot to adjust the throttle position to the appropriate setting for the current altitude.

Explanation

When "LVR CLB" flashes white on the Flight Mode Annunciator (FMA), it indicates that the aircraft is above the altitude of thrust reduction. This means that the throttles should be in the climb (CL) position at this altitude, but they are not. The FMA is alerting the pilot to adjust the throttle position to the appropriate setting for the current altitude.

7. "SPEED BRK" message displayed on the FMA means:

Speed brakes are not functioning properly.

Speed brakes are deployed.

Speed brakes are retracted.

Speed brakes are armed and ready for deployment.

The "SPEED BRK" message displayed on the FMA indicates that the speed brakes are armed and ready for deployment. This means that the aircraft's speed brakes have been activated and are in a state where they can be deployed if necessary.

Explanation

The "SPEED BRK" message displayed on the FMA indicates that the speed brakes are armed and ready for deployment. This means that the aircraft's speed brakes have been activated and are in a state where they can be deployed if necessary.

8. ASYM amber message (FMA) means:

One thrust lever is set out of climb notch (both engines running).

Asymmetric power is established due to FADEC malfunction.

Asymmetric power is established due to TLA resolver fault.

Alerts the pilot about an asymmetric flap deployment, affecting lift and drag during approach and landing.

The correct answer is "One thrust lever is set out of climb notch (both engines running)." This means that one of the thrust levers is not in the appropriate position for climbing, even though both engines are running. This could indicate a mistake or error in the pilot's actions, as the climb notch is a specific setting for climbing.

Explanation

The correct answer is "One thrust lever is set out of climb notch (both engines running)." This means that one of the thrust levers is not in the appropriate position for climbing, even though both engines are running. This could indicate a mistake or error in the pilot's actions, as the climb notch is a specific setting for climbing.

9. MCT amber message (in the left part of the FMA) means:

Throttles are not in MCT position after engine failure when speed is > green dot (VFTO).

Throttles are not in MCT position after engine failure in flight.

Indicates that the engine's maximum continuous thrust has been exceeded, potentially causing engine damage.

Indicates a malfunction in the aircraft's engine control system, resulting in reduced thrust output.

The MCT amber message indicates that the throttles are not in the MCT (Maximum Continuous Thrust) position after an engine failure in flight. This means that the pilot has not properly adjusted the throttle settings to maintain the appropriate thrust level for continued flight after an engine failure. It serves as a reminder for the pilot to adjust the throttles accordingly to ensure the aircraft's performance and safety.

Explanation

The MCT amber message indicates that the throttles are not in the MCT (Maximum Continuous Thrust) position after an engine failure in flight. This means that the pilot has not properly adjusted the throttle settings to maintain the appropriate thrust level for continued flight after an engine failure. It serves as a reminder for the pilot to adjust the throttles accordingly to ensure the aircraft's performance and safety.

10. What does the "LAND" message on the FMA indicate during approach and landing?

Aircraft has descended to a certain altitude for landing.

Landing gear is down and locked.

Landing clearance has been received from ATC.

Aircraft is cleared for landing.

The "LAND" message on the FMA indicates that the landing gear of the aircraft is down and locked. This message is displayed during approach and landing to inform the pilots that the landing gear is properly extended and secured in the landing position. It is an important indication for the pilots to ensure the safe landing of the aircraft.

Explanation

The "LAND" message on the FMA indicates that the landing gear of the aircraft is down and locked. This message is displayed during approach and landing to inform the pilots that the landing gear is properly extended and secured in the landing position. It is an important indication for the pilots to ensure the safe landing of the aircraft.
