Of course, navigation to or from a VOR station does
no good unless you know where that station is.
Fortunately, pilots always fly with aeronautical
sectional charts (Figure 3), which depict the locations
of VOR stations. The VOR station (position A) is
located in the middle of the compass rose, which has
markings every 5 degrees, larger markings every 10
degrees, and numbers every 30 degrees.
A box in the vicinity of the compass rose lists the
name, Morse code identification, and frequency of
the VOR ground station (position B). In Figure 3, the
VOR frequency is 112.3. Don’t worry about the “CH
70”. That’s the frequency for military pilots.
Your VOR Equipment
Most airplanes have one or more VOR receivers on board; each one is connected to a VOR display
that looks similar to the one shown in Figure 4. When pilots refer to “the VOR in their airplane,” they
are usually talking about the display, which consists of five main components:
· An index at the top of the display, which points to the selected course.
· A vertical needle (also known as a course deviation indicator, or CDI) that swings right or left.
· A flag in the form of a triangle that points up or down, or a red-and-white striped flag. A triangle
pointing up represents a “TO” indication; a triangle pointing down represents a “FROM”
indication; and a red-and-white striped
flag represents an “OFF” indication. In
this chapter, I’ll use the words TO,
FROM, and OFF to represent these
three flag indications.
· An omni-bearing selector (OBS)the
knob you turn to select a course.
· A circular, moveable compass card,
which is adjusted by rotating the OBS.
(Rotating the OBS causes a different
course value on the compass card to
move to the index.)
