Part-time operation, such as for a control tower, is indicated with an aster-
isk (*) to the right of an airport frequency.
The frequencies associated with class B or C airspace, CTA or TMA are
VFR frequencies. Airports which have one of these categories of frequen-
cies also have APR and DEP which are IFR frequencies.
Where required, APR, DEP, CL B, CL C, CTA, and TMA frequencies are
sectorized. That is, a frequency may be used only within a certain range
of radials from a designated reference location. The format for displaying
the sectorization is to show the frequency first, followed by the identifier of
the associated reference point, fol-
lowed next by the associated altitude
restrictions. For example, figure 3-
154 shows that the Orlando
approach control frequency 121.10
