How many electric cooling fans are there and what is their purpose?
Four electric cooling fans for cooling G1000 components
They operate when the Electric Master and Avionics switches are turned on.
What happens if a cooling fan fails in the system?
Displays PFD FAN FAIL, MFD FAN FAIL, or GIA FAN FAIL message
Overheating can lead to automatic shutdown of affected components.
Fill in the blank: The GIA cooling fan is located _______.
In the rear avionics rack
True or False: The GRS77 AHRS uses only mechanical sensors to determine the aircraft’s orientation.
False
The GRS77 uses solid-state accelerometers, tilt sensors, and rate sensors.
What should be avoided when loading baggage in relation to the rear avionics fan?
Obstructing the air intakes
This can lead to cooling issues and potential component failure.
