Approach Notes
Waypoints
The database waypoints which describe the TSO
C129a
GPS approaches correspond with the
waypoints which appear on the approach procedure
charts whenever possible. VORs, NDBs, and named
Intersections will appear in the approach sequence as
they are on the charts. The Rifle, Colorado VOR will
be identified RIL, the Turno Locator/Outer-Marker
(LOM) at Salem, Oregon will be identified SL, the
Forsyth NDB, at Forsyth Montana will be identified
FOR, and the HIKOX intersection, used as an Initial
Approach Fix (IAF) for VOR/DME or GPS RWY 3
approach at Casper Wyoming, will be identified as
HIKOX.
Many waypoints that are specific to
TSO-C129a/JTSO- C129a GPS approaches require
that a name be assigned to them, such as an Initial
Approach Fix (IAF) which is shown on the approach
procedure chart as a radial and distance from a VOR.
These waypoints may or may not appear on the
approach procedure charts. Jeppesen includes the
names of many of these waypoints on their approach
procedure charts; however, these names are usually not
included on National Ocean Service (NOS) charts.
TSO/JTSO
C129 Overlay
TSO-C129a/JTSO C129a requires the equipment to
prompt the pilot to enter the local altimeter setting, if
not already entered, at 3 nm inbound to Final
Approach Fix, FAF. It also requires that the
equipment change RAIM alarm limits from 1 nm to
0.3 nm and to begin changing CDI sensitivity from 1
nm full-scale deflection to 0.3 nm full-scale deflection
when 2 nm inbound to the FAF. The TSO also
requires that the final leg of the approach be defined
as a path between the FAF and the MAP waypoints
(bearings to or from waypoints are not allowed for the
final segment). For these reasons, a GPS TSO C129a
approach must always have an FAF lying on the
inbound course to the MAP, even when there is no
9-77
