TACAN and VOR Procedures
3.
If a T-45C pilot tunes in a TACAN channel
associated with a VORTAC, operating
characteristics will appear the same as for
any TACAN: bearing and DME
4.
A T-45C pilot may tune a VORTAC VOR
frequency, which will enable reception of
VORTAC (VOR) bearing (only) information
on the HSI
NOTE: When using a VORTAC selected by
channel designation, if bearing information
becomes lost, it may be possible to retain DME
via the TACAN channel already selected and to
regain bearing information by tuning in the
VORTAC VHF frequency on the VOR receiver.

be installed in aircraft to enable automatically

by civilian aircraft, e.g., commercial airliners.
