We use the longer
abbreviations as a way to make them more
meaningful rather than trying to remember the
names for MT, MI, MA, MS, MN, etc.
Under the entry for Great Falls, take a look at that chart, note that the words
Great Falls, App(R)/Dep(R), Twr, and Gnd are in
bold. When the words and letters are in bold type,
this indicates the names to be used in voice
communications. For example, a call to approach
control would be “Great Falls Approach,” not
“Great Falls International Approach” because the
word Int’l is not in bold. At Hailey, Idaho, it is easy
to see that a call to the tower would be “Hailey
shown on the face of the chart near the location of
their antennae. This can be just above the navaid
frequency box, above the airports where the
remote sites might be located, or at remote sites
indicated by a small dot enclosed by a small circle.
Since the first two digits of all Flight Service Station
frequencies are “12” these two numbers do not
appear with the FSS frequencies. One of the
original FSS frequencies, 122.1 MHz, has almost
disappeared. In the first comm receivers, there
was a limited number of VHF transmit frequencies
and 122.1 was one of them. Most Flight Service
Stations were able to receive on that frequency
and transmit back on the VOR. Today, however,
For discussion purposes, a section of the new
“Comm Tabs” from US(LO) 7/8 is illustrated. The
first entry for Great Falls, Mont shows “p8B” to the
right of the city name. These characters indicate
that the Great Falls airport can be found on panel
8 of the chart in quadrant B. Each panel is labeled
at the top of the “Zigdex.” Each panel is included
on the chart between the “outside” folds. These
are the folds that are naturally on the left and right
when you open to only one section of the chart.
When the chart is opened this way, there are four
sections labeled A, B, C, and D. This indexing
system on the Comm Tabs negates the need for
the “City Location Guide” which will disappear.
Isn't VIBAL a intersection in France?
