USE OF THE IND­350
1.
General ­ Almost without exception, military aircraft make use of a radio compass system
as the primary navigation instrument. In the T­34C, this system's cockpit display is the radio
magnetic indicator (RMI). In its role as a compass, you have used this instrument since the
Contact Stage. In the Instrument Stage, you will combine this usage with the interpretation of
aircraft position as depicted on the RMI's VOR and TACAN needles.
The RMI's principal shortcoming is its small size. Just as it is difficult to resolve small heading
differences on the face of this instrument, it is also difficult to recognize small deviations from
your desired course as depicted on the VOR and TACAN needles, hence the IND­350.
The course deviation indicator (CDI) is the major component of the IND­350; its other
components are the Omni Bearing Selector (OBS) and TO/FROM indicator.
It is important to reemphasize here that, in the event of a discrepancy between RMI and CDI, rely
upon the RMI for course information.
To properly use the IND­350, you must first twist the desired course with the OBS. Then, set the
VOR/TACAN switch to the appropriate position. The TO/FROM indicator will then show
whether the course selected will take you TO or FROM the NAVAID tuned. If you are within
10º of the course selected, the course deviation indicator will provide a picture of relative
position.
With a VOR frequency or TACAN channel selected, each "mark" on the CDI represents 2º of
deviation (full scale deflection of 10º). With a localizer frequency selected and the VOR/TACAN
switch toggled to "VOR," each mark on the CDI represents ½° of deviation (full scale deflection
of 2½°).
Figure 6­5 presents a typical situation. The selected course inbound to the station is 360º and the
aircraft is 5º left of course (imagine your aircraft on the tail of the VOR needle and at the center of
the CDI). You must, therefore, turn right (into the CDI) to establish the aircraft on the desired
