7.2.3 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. 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°. Make sure 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.

2. Adjust the ICS volume to a comfortable level.
3. Plug in a headset at each Cockpit ICS position. One at a time, plug a headset into
each left and right CABIN ICS jack location (if installed) (one headset on right,
one headset on left).
4. Check the following:
• Two-way communication between each CABIN ICS jack position.
• CABIN ICS position cannot hear the pilot and copilot.
• CABIN ICS positions cannot be heard by the pilot or copilot.
5. Select COM1 MIC and AUDIO on the GMA 1347/1360D.
6. Make sure INTR COM is deselected. Check for an active (green) COM1 fre-
