It scans and memorizes fault information from connected aircraft systems

It controls the aircraft systems

It sends real-time data to the pilots

How can the memorized fault information be accessed?

On the MCDU or printed out on the printer

It cannot be accessed; it is only stored

What is the function of the Central Maintenance Computer (CMC) as shown in Figure 4: Reporting Mode?

It reports and records aircraft maintenance data.

It controls the aircraft's entertainment system.

It manages the aircraft's fuel efficiency.

It navigates the aircraft during flight.

What is the purpose of using Interactive Mode on the CMCs?

For functional checks and fault investigation

To communicate with the air traffic control

What is the function of the output test in Interactive Mode?

It is a function in the cockpit that needs the engineer to interact with the procedure

It is a test for moving parts of the aircraft system

It is a test that is carried out on the ground only

Where can the results of the tests in Interactive Mode be displayed?

On the MCDU, printed on the printer, or sent via the data-link to the home base

Only sent via the data-link to the home base

What is the primary function of the Central Maintenance Computer (CMC) as depicted in the diagram?

To provide an interactive mode for maintenance

To control the aircraft's engines

To manage the aircraft's fuel systems

To serve as the aircraft's primary flight computer

What is the BITE an acronym for in the context of aircraft maintenance systems?

Binary Integrated Test Equipment

Background Interface Testing Element

Where is the BITE located?

Inside each aircraft system computer

Within the operational parts of the computer

In the central maintenance computer

Is the BITE dependent on the operational parts of the aircraft system computer?

No, it is completely independent from the operational parts

Yes, it is part of the operational system

Yes, but only during system tests

No, it operates only when the aircraft is on the ground

What are the two functions of the BITE?

To detect failures and to perform system tests on the ground

To detect failures and to perform system tests in the air

To perform system tests on the ground and to enhance performance

To control the aircraft systems and to communicate with the CMC

When does the BITE perform system tests?

Only when the aircraft is on the ground

Only when the aircraft is in the air

When the aircraft system computer is offline

How is the power up test initiated?

Automatically when electrical power is switched on

Remotely from the control tower

What does the acronym BITE stand for in the context of aircraft maintenance systems?

Battery Initiated Test Execution

Backup Instrumentation Testing Engine

What is the function of the printer in the context of the Central Maintenance Computer (CMC) system?

To print the maintenance schedule

To print the aircraft's navigation maps

What is the purpose of the Data Link in the Central Maintenance Computer (CMC) system?

To link the CMC with external maintenance systems

To provide internet access to passengers

To synchronize the flight data with the black box

To control the in-flight entertainment systems

What happens if the CMC fails during flight?

The standby CMC will automatically become active

The aircraft will not be able to fly

Maintenance activities can continue as normal

Data can still be read from the MCDU

What is the purpose of having a standby CMC installed?

To replace the normal CMC if it fails

To control the aircraft's navigation systems

How can the standby CMC be activated on some aircraft?

By pressing a control push-button

By restarting the aircraft systems

It activates automatically without any action
