Approach NotesWaypoints The database waypoints which describe the TSOC129a GPS approaches correspond with thewaypoints which appear on the approach procedurecharts whenever possible. VORs, NDBs, and namedIntersections will appear in the approach sequence asthey are on the charts. The Rifle, Colorado VOR willbe identified RIL, the Turno Locator/Outer-Marker(LOM) at Salem, Oregon will be identified SL, theForsyth NDB, at Forsyth Montana will be identifiedFOR, and the HIKOX intersection, used as an InitialApproach Fix (IAF) for VOR/DME or GPS RWY 3approach at Casper Wyoming, will be identified asHIKOX.Many waypoints that are specific toTSO-C129a/JTSO- C129a GPS approaches requirethat a name be assigned to them, such as an InitialApproach Fix (IAF) which is shown on the approachprocedure chart as a radial and distance from a VOR.These waypoints may or may not appear on theapproach procedure charts. Jeppesen includes thenames of many of these waypoints on their approachprocedure charts; however, these names are usually notincluded on National Ocean Service (NOS) charts.TSO/JTSOC129 OverlayTSO-C129a/JTSO C129a requires the equipment toprompt the pilot to enter the local altimeter setting, ifnot already entered, at 3 nm inbound to FinalApproach Fix, FAF. It also requires that theequipment change RAIM alarm limits from 1 nm to0.3 nm and to begin changing CDI sensitivity from 1nm full-scale deflection to 0.3 nm full-scale deflectionwhen 2 nm inbound to the FAF. The TSO alsorequires that the final leg of the approach be definedas a path between the FAF and the MAP waypoints(bearings to or from waypoints are not allowed for thefinal segment). For these reasons, a GPS TSO C129aapproach must always have an FAF lying on theinbound course to the MAP, even when there is no9-77Approach Notes
