Flaps-in-motion Discrete Input Check

To perform this check, all G1000 and GFC 700 equipment must be installed and operational. Start PFD1
in Configuration Mode and go to the GIA Page Group and select the GIA I/O Configuration Page using
the FMS knob. Perform the following checks:
1. Verify the DATA indicators of the discrete inputs labeled 'FLAP EXTEND' and 'FLAP
RETRACT' show an invalid condition.
2. Extend the flaps down. While the flaps are traveling down, check that the DATA indicator of the
discrete input labeled 'FLAP EXTEND' changes to a valid condition.
3. When the flap motion is completed, verify the DATA indicators of the discrete inputs labeled
'FLAP EXTEND' and 'FLAP RETRACT' show an invalid condition.
4. Retract the flaps up. While the flaps are traveling up, check that the DATA indicator of the
discrete input labeled 'FLAP RETRACT' changes to a valid condition.
5. When the flap motion is completed, verify the DATA indicators of the discrete inputs labeled
'FLAP EXTEND' and 'FLAP RETRACT' show an invalid condition.
6. Repeat steps 1 through 5 for GIA2.
7. The flap discrete input check is complete.
