VOR/LOC/GS Test
Check the VOR, ILS, and Glideslope functions with ramp test equipment. Operate the
equipment according to the test equipment manufacturer's instructions. Adjust the RF signal to
a level adequate to perform the test. Note that the PFD CDI will not show a course deviation bar
unless a valid VHF NAV frequency is tuned. Simulate a VOR signal on radial 000° with a
course-width of 20°. Verify full-scale deflection of the CDI while applying a 10° deviation
signal. Exercise the CDI with both right and left deviations for both NAV 1 and 2. Exercise the
Glideslope indicator with up and down deviation indications.
7.1.4 GMA 1347D
Original GMA 1347D Reinstalled:
No software or configuration loading is required if the original GMA 1347D is reinstalled. This
does not include units that were returned for repair as their software and configuration files are
deleted during the repair testing process.
Original GMAs Installed in Opposite Locations for Troubleshooting:
If the original GMA #1 and GMA #2 are installed in opposite locations for troubleshooting,
configuration loading is required.
Load the following files:
GMA1 Configuration
•
GMA2 Configuration
•
GMA1/2 Files for optional equipment installed on the aircraft (i.e. ADF, HF radio, etc.).
•
New or Repaired GMA 1347D Installed:
If a new or repaired GMA 1347D is installed, load the following files after removing the
Supplemental Database cards from the bottom slots of each display. Note which card was
removed from the MFD so it may be identified later for reinsertion in the MFD when software
and configuration loading is complete. It contains a FliteChart or Chartview database which is
only used by the MFD. Reinstall all the cards after the software and configuration file loads are
complete.
