3.3
In-Flight Final Calibration Adjustment
(continued)
If the calibration is unsuccessful, the system will return to flashing slowly for 5
seconds; then will transition again to flashing quickly for another 5 seconds.
This sequence will repeat until the calibration is successful.
Press and hold both the top and bottom button for two seconds to exit the calibration mode.
After a successful calibration, at a safe altitude, fly a simulated
approach using the POH recommended landing approach
speed, power, and flap extension. Verify that the given On-
speed (five dots) is lit /–5 knots of the POH referenced
speed. Without adjusting power, pitch aircraft nose up, slowing
the aircraft so that the Indexer Computer displays two
amber
LEDs. Verify LAA audio is active and stall warning is not.
If verification fails, repeat section 3.3.
NOTE
Pressing and holding both top and bottom buttons
simultaneously for two seconds at any time exits the calibration
NOTE
Final Lift Transducer Installation
3.4
Once the location of the Lift Transducer has been determined and the system has been
calibrated, mark the center of the horizontal slots on the Lift Transducer mounting plate.
Disconnect the wiring and remove the Lift Transducer from the wing.
Install rivet nuts or equivalent in the horizontal slot center locations previously marked.
Reconnect and reinstall the Lift Transducer, using all 4 screws.
Precautions
3.5
DO NOT
paint or otherwise coat the vane of the Lift Transducer. All parts are adequately
protected against corrosion. Any additional coating will interfere with proper operation.
DO NOT
attempt to bend the Lift Transducer vane to obtain any adjustment. Refer to Section
3.0 of these instructions for the proper method of adjusting the Lift Transducer.
Weight and Balance
3.6
The Aircraft Weight and Balance and Equipment List for the aircraft should be updated to
include the installation of the SCc components listed in Tables 1, 2, and 3.
TROUBLESHOOTING
4.0
System Removal
4.1
To disconnect the Indexer Computer from the Base Assembly, insert a flat-head screwdriver
into the slot at the end of each leg. Lift up to release. Rotate the cover to access the screw
heads. Pull gently on the Indexer Computer to remove the system after the cover has been
lifted.
Remove Lift Transducer by unscrewing from rivnuts on wing. Cover the location with a cover
plate if necessary.
