IV. VOR/DME
A. Location and use of VOR/DME equipment controls and indicators for
tuning/identifying 2.7.5.1.1.1
1. COMM/NAV control transfer panel: CDI VOR switch/light must be

selected to route VOR navigation information to the HSI and CDI
Transfer Panel
2. Communication control panel: VOR and TACAN toggle switches
Fig 6: Communication
provide routing of Morse code information through
Control Panel
intercommunication system (ICS) to pilot’s headset
3. VOR/ILS control panel: same as VOR controls and indicators

(ref. II.A.3)
Control Panel
5. HSI
a. Includes VOR controls and indicators (ref. III.A.4)
b. Includes TACAN range counter information (ref. II.A.4)
NOTE: The TACAN pointer will continue to search if the
station is not a VORTAC.
B. Tuning/identifying
1. This procedure begins just as in TACAN and VOR above:
(Sections II.A.3. and III.A.3.)
a. Find VOR station frequency and TACAN station channel (or
VORTAC frequency/channel) on approach plates/charts
b. Ensure COMM/NAV transfer panel is set up for VOR control
and CDI display
c.
Verify VOR/ILS control panel is on with volume turned up and
select frequency for bearing information
d. Verify TACAN control panel is on with volume turned up and
select channel for DME information
e. Position communication panel VOR toggle switch ON. Verify
the 3-letter Morse code and/or recorded voice identifier of
selected station
f.
Position communication panel TACAN toggle switch ON and
