Flashcards in AHRS Deck (10):
1

What is the AHRS system made up of?

-AHRU 1 and 2
-Flux valves
-AHRS control panel 1 and 2
-Remote memory module 1 and 2

2

What does the AHRS system calculate?

-Altitude
-Magnetic heading
-Lateral Accelerations
-Angular rates
-Vertical speed

3

What will you get if AHRS lubber line is off by 4°

HDG MISMATCH

4

What are the two modes of the AHRS?

Standard mode and Reduced Performance Mode

5

What are the standard modes?

What are the reduced performance modes?

Normal, slave, alignment

Basic and DG

6

What is normal mode?

What is slaved mode?

When does it align?

Normal: TAS from ADC used to compensate for acceleration induced errors.

Slaved: Flux valve slaves heading.

On system activation.

7

What are the reduced operation modes of the AHRS?

Basic and DG

8

What is the basic mode of the AHRS?

It has no correction for acceleration. It becomes a conventional AI. This happens when the flux valve fails

9

What happens if the flux valve fails?

It becomes a basic gyro.

10

Is TAS required for AHRS to function?

No
