- A.
  
  EICAS alert message NAV ADIRU INERTIAL
- B.
  
  EICAS memo message ADIRU ALIGN MODE
- C.
  
  CDU scrachpad message ADIRU ALIGN
- D.
  
  CDU scratchpad message ENTER ADIRU POSITION
Correct Answer
B. EICAS memo message ADIRU ALIGN MODE

Explanation
When the ADIRU (Air Data Inertial Reference Unit) is in the alignment mode, the EICAS (Engine Indicating and Crew Alerting System) displays a memo message that says "ADIRU ALIGN MODE". This message indicates that the ADIRU is currently aligning itself and is not yet ready for navigation. It serves as a reminder to the crew that they should wait until the alignment process is complete before relying on the ADIRU for accurate navigation information.

How often is a complete ADIRU alignment recommended?
- A.
  
  Every 15 hours
- B.
  
  Every 24 hours
- C.
  
  Whenever the total time in the nivigation mode is expected to exceed 15 hours.
- D.
  
  Whenever the total time in the navigation mode is expected to exceed 24 hours.
Correct Answer
D. Whenever the total time in the navigation mode is expected to exceed 24 hours.

Explanation
A complete ADIRU alignment is recommended whenever the total time in the navigation mode is expected to exceed 24 hours. This means that after 24 hours of continuous navigation mode operation, it is recommended to perform a complete ADIRU alignment to ensure accurate and reliable navigation data. This alignment helps maintain the accuracy and integrity of the aircraft's navigation system over extended periods of operation.

Which of the following are data sources for the ADIRU?
- A.
  
  Static ports only
- B.
  
  Air data modules,AOA sensors, and TAT probe
- C.
  
  Air data modules only
- D.
  
  AOA sensors and TAT probe only.
Correct Answer
B. Air data modules,AOA sensors, and TAT probe

Explanation
The ADIRU (Air Data Inertial Reference Unit) is a system in an aircraft that provides data regarding the aircraft's position, attitude, and airspeed. It receives information from various sources to calculate this data. The correct answer states that the data sources for the ADIRU include air data modules, AOA (Angle of Attack) sensors, and TAT (Total Air Temperature) probe. Air data modules provide information about the aircraft's air pressure, temperature, and airspeed. AOA sensors measure the angle between the aircraft's longitudinal axis and the oncoming airflow. The TAT probe measures the total air temperature. Therefore, these three sources provide crucial data for the ADIRU to accurately determine the aircraft's position and attitude.

Which of the following are data sources for the SAARU?
- A.
  
  Air data modules only
- B.
  
  Static ports only
- C.
  
  Air data modules, AOA sensors, and TAT probe
- D.
  
  AOA sensors and TAT probe only.
Correct Answer
C. Air data modules, AOA sensors, and TAT probe

Explanation
The SAARU (Standby Attitude and Air Data Reference Unit) requires data from various sources to function properly. These sources include air data modules, AOA (Angle of Attack) sensors, and TAT (Total Air Temperature) probe. These components provide essential information such as airspeed, altitude, angle of attack, and temperature to the SAARU, allowing it to accurately calculate and display attitude and air data information to the pilot. Therefore, the correct answer is air data modules, AOA sensors, and TAT probe.

Which one of the following is inoperative with dual FMC failure?
- A.
  
  LNAV
- B.
  
  VNAV
- C.
  
  MAP display
- D.
  
  Both CDUs
Correct Answer
B. VNAV

Explanation
With dual FMC failure, the VNAV (Vertical Navigation) function becomes inoperative. The FMC is responsible for calculating and controlling the aircraft's vertical navigation, including altitude and vertical speed. Without functioning FMCs, the aircraft is unable to accurately manage vertical navigation, making the VNAV inoperative. LNAV (Lateral Navigation) and MAP display are not directly dependent on the FMCs and may still be operational. The CDUs (Control Display Units) are input devices for the FMCs and would also be inoperative without functioning FMCs.

Rate this question:
47.

When will the FMC not automatically sequence the active waypoint in flight?
- A.
  
  When more than 21 NM off the active route and not on an offset.
- B.
  
  When more than 2.5 NM off the active route and not on an offset.
- C.
  
  When passing over the waypoiny in HDG SEL.
- D.
  
  When passing over the PROCEDURE HOLD waypoint on an approach.
Correct Answer
A. When more than 21 NM off the active route and not on an offset.

Explanation
The FMC (Flight Management Computer) will not automatically sequence the active waypoint in flight when the aircraft is more than 21 NM (nautical miles) off the active route and not on an offset. In other words, if the aircraft deviates significantly from the planned route and is not following any offset procedures, the FMC will not automatically advance to the next waypoint. This is likely to prevent the aircraft from continuing on an incorrect path and to ensure the pilots are aware of the deviation and can take appropriate action.
