Carbon Monoxide Detector Functionality

What type of maintenance does a carbon monoxide detector require?

What action does the carbon monoxide detector perform at every power up?

What message is displayed if the carbon monoxide detector fails?

Which of the following is not a function of the carbon monoxide detector during power up?

Which statement about the carbon monoxide detector's maintenance is true?

What indicates that the landing gear is safely down and locked?

What happens when the activation of all three downlock switches occurs?

Under which condition do the green landing gear lights become difficult to see during daytime?

What occurs when the landing gear begins to retract?

What is indicated by the red light on the instrument panel?

Carbon Monoxide Detector Operation

Requires no periodic servicing or maintenance for effective operation.
Executes a self-diagnostic check each time the device is powered up.
If the system detects a malfunction, it displays the message ‘CO DET FAIL’ in the messages window.
PFD (Primary Flight Display) provides clear notification of unit failure for user awareness.

Landing Gear System

Airplane equipped with retractable, tricycle air-oil strut type landing gear, hydraulically operated.
Operation powered by an electrically reversible pump.
Gear position indications:
- Three green lights for gear down and locked.
- One red light at the top of the instrument panel for unsafe gear position.

Gear Retraction and Locking

No indication light for fully retracted gear; all lights must be off.
Downlock hooks engage as the landing gear swings to the down and locked position.
Activation of individual downlock switches triggers green lights, confirming gear is down and locked.
All three downlock switches' activation turns off the hydraulic pump.

Light Visibility Adjustments

Green landing gear lights automatically dim if NAV LIGHTS switch is ON during the daytime.
In aircraft without a DAY/NIGHT switch, visibility of gear lights may be poor.
DAY/NIGHT switch must be in DAY position during daytime for clear visibility of gear lights.

Gear Unsafe Indication

During gear retraction, down limit switches engage, allowing the gear unsafe light to illuminate.
Gear unsafe light remains active until the gear is fully retracted and up limit switches are engaged, indicating a shift to their normally open (NO) circuit.

This quiz focuses on the operation of carbon monoxide detectors, emphasizing their self-diagnostic features and maintenance requirements. Understand how these detectors alert users in case of failures. Test your knowledge on the messages displayed and their meanings.
