Figure 281. ADS-GPS Receiver Installation (Actual Number of Studs Used May Differ)
Note:
The number of studs may vary from 2 to 4.
2. Secure the GPS RECEIVER with the lock nuts and washers previously removed. Hardware may be #6-32 or #8-32 size. Torque the #6 lock nuts to 8.0-9.5 in-lbs and #8 lock nuts to 11.3-13.3 in-lbs.
Note:
The mounting holes may be enlarged to a diameter of 3/16” (.1875”).
3. Connect the coax ADS-B GPS Antenna cable connector to the GPS RECEIVER.
4. Connect the D9119P to the GPS RECEIVER.
Verification Method
1. Take the aircraft outside and place in clear view of the sky.
2. Turn knob on control head to ATL mode. Wait for the display to change from ALT to GND. If not, there is something wrong with the squat switch or setting.
Note:
It may take up to 2 min for it to cycle to GND.
3. Press FN button twice on the TC20 until ADS-B POSN diagnostic screen is displayed. It will display the following for position fix.
4. After 2 min the GPS should have obtained a position fix. If no fix is determined and an error of “WARNING No ADSB Pos” shows up, call ICON for further support.
