BY ORDER OF THE SECRETARY OF THE AIR FORCE AIR FORCE ...

AFMAN 11-217V1 3 JANUARY 2005 107
7.1.4.2.2. Loss of the Morse code station identification will immediately cause
the alphanumeric visual display to disappear, or a warning to be displayed.
7.1.4.2.2.1. WARNING: It is imperative that crews are cognizant of what
station identification is being displayed. For example, if the station
identification being displayed is from the DME portion of a VOR/DME
station, then only the DME alphanumeric display may be used. The VOR
azimuth station identification must still be monitored aurally.
7.1.4.2.2.2. WARNING: Voice communication is possible on VOR, ILS, and
ADF frequencies. The only positive method of identifying a station is by its
Morse code identifier (either aurally or alphanumeric display) or the recorded
automatic voice identification, indicated by the word “VOR” following the
station name. Listening to other voice transmissions by a Flight Service
Station or other facility (ex. (TWEB)) is not a reliable method of station
identification and shall not be used. Consult FLIP documents to determine the
availability of specific stations.
7.1.4.2.2.3. MAJCOMs will determine which aircraft can use this method to
monitor NAVAIDS.
7.1.5. Select. Select proper position for the navigation system switches.
7.1.6. Set. Set the selector switches to display the desired information on the navigation
instruments.
7.1.7. Monitor. Monitor the course warning flag (if installed) and, the aural or
alphanumeric display continuously to ensure adequate signal reception strength.
7.1.8. Check. Check the appropriate instrument indicators for proper operation.
7.2. Homing to a Station. Tune and identify the station. Turn the aircraft in the shorter
direction to place the head of the bearing pointer under the top index of the RMI/BDHI or
upper lubber line of the HSI. Adjust aircraft heading, as necessary, to keep the bearing
pointer under the top index or upper lubber line. Since homing does not incorporate wind
drift correction, in a crosswind the aircraft follows a curved path to the station (Figure 7.1).
Therefore, homing should be used only in the event maintaining course is not required.
