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. Select the appropriate HSI source by using the CDI softkey.
The PFD HSI does 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 deviation indicator with up and down deviation indications.
If no other service is to be performed, continue to the return-to-service checks in Section 8.
