TACAN and VOR Procedures
for airway navigation. Present
FAA and FCC standards permit as
many as 20 VORs to use the
same frequency. The problem is
that the usable range of VORs
decreases as altitude increases,
due to overlapping VOR signals
from transmitters using the same
frequencies
(2) SSV restrictions apply for VOR
maximum range to random/
unpublished route navigation legs.
There are different ranges for
terminal (T), low (L), and high (H)
facilities. High VORs have the
greatest allowable range: 130 nm.
SSV restrictions do not apply to
published IFR routes or
procedures
(a) T (terminal) VOR: 1,000 ft
AGL up to and including
12,000 ft AGL at radial
distances out to 25 nm.
Terminal VORs do not appear
on high altitude enroute
charts
(b) L (low) VOR: 1,000 ft AGL up
to and including 18,000 ft
AGL at a radius out to 40 nm
(c) H (high) VOR:
(i)
From 1,000 ft AGL up to
and including 14,500 ft
AGL at a radial distance
out to 40 nm
(ii) From 14,500 ft AGL up to
and including 60,000 ft
AGL at a radial distance
out to 100 nm
