T-45C ADV INav-03
If you feel it necessary to again show the graphic depicting
VOR/TACAN Cones of Confusion, call up Seg 3/frame 6.
NOTE: The acronym VORTAC describes a facility
in which a VOR and a TACAN station are collocated.
Operating characteristics are the same as VOR/
Same as VOR plus DME information
Both VOR frequency and TACAN channel must
be tuned (T-45C)
D. GPS and INS theory and operating characteristics
Sg 4, fr 5: Introduction to INav
INTRODUCTION to INAV
THEORY: GPS is a 24+ satellite-based
Responsibilities of ATC
navigation, positioning, and time transfer
system. GPS satellites transmit identity,
calibration, and time signals. Aircraft use
passive receivers to process that satellite data.
Triangulation and sensed aircraft flight path
angles are used to compute aircraft position.
Sg 4, fr 6: Global Positioning
Altitude can also be extrapolated using GPS
NOTE: The T-45C does not use GPS to
generate cockpit altitude information. The
T-45C GPS and INS are linked together in the
Global Positioning System/Inertial Navigation
GPS Standard Position Service (SPS) has 100
meters horizontal positioning accuracy with a
probability of 95%
