3.10.1.3.1 GPS Operation Check
1.
Press the Status button to open the GPS Status screen.
2.
Verify that GPS information is being displayed and that the “GPS” operating mode is “WAAS”. If
the information is missing perform the following:
•
The unit may not be able to establish communication with a satellite due to an obstruction of the
GPS reception. Either move the aircraft to an area with better GPS reception or use a GPS
Simulator to generate the necessary signal.
•
If the GPS reception continues to be a problem, check the GPS antenna installation.
3.
Verify that the GPS position agrees with a known reference point.
4.
Verify that the signal bars are showing at least 40 -50% in the GPS Receiver Information Packet for
all the GPS/SBAS satellites in view.
5.
Turn ON other avionics and verify that the signal bars are showing at least 40 -50% in the GPS
Receiver Information Packet for the satellites do not degrade significantly and position remains steady.
6.
Turn ON VHF Com radios and verify that the signal bars are showing at least 40 -50% in the GPS
Receiver Information Packet for the satellites do not degrade significantly and position remains
steady.
7.
If the aircraft is TAS/TCAS equipped, turn on the TAS/TCAS system and verify that the signal bars
are showing at least 40 -50% in the GPS Receiver Information Packet for the satellites do not
degrade significantly and position remains steady.
8.
Any GPS interference (significant degrade in signal strength) must be resolved prior to completing
the installation. Use the troubleshooting procedures in the maintenance section for help.
