![]() The FMS display as a collection of waypoints with a title that Once loaded, a GPS or RNAV (GPS) approach is shown in You to enter or delete, separately or individually, waypoints Then loads all of the waypoints associated with that procedureįrom the database into the flight route. As previously noted, approaches must be selectedįrom a specific approach menu in the FMS. GPS RNAV units capable of flying approaches to LPV minimums.įigure 3-50 shows a GPS approach loaded into an FMS/GPS GPS/WAAS receivers to generate vertical guidance similar Vertical guidance.” Procedures with LPV minimums use GPS information to generate lateral guidance, and IFR-approved LPV can be thought of as “localizer performance with GPS receivers does not make the aircraft capable of flying Non- WAAS-capable or non- WAAS-equipped IFR approved ![]() It isĪlso important to understand that the VNAV function of Installed in an aircraft, and what it is approved to do. It is very important to know what kind of equipment is Lateral and vertical profile shown on the approach chart in To load an RNAV approach and receive guidance along the The WAAS enabled GPS receiver shown in Figure 3-49 allows the pilot Signals into its position determining processing. Meters.) To make use of WAAS, however, the aircraft mustīe equipped with an IFR approved GPS receiver with WAAS signal reception that integrates WAAS error correction Of vertical position information is increased to within 3 (Note: WAAS makes use of aĬollection of ground stations that are used to detect andĬorrect inaccuracies in the position information derived from Wide area augmentation system (WAAS) to improve GPSĪccuracy for this purpose. VNAV minimums make use of certified barometric VNAV (baro- VNAV) systems for vertical guidance and/or the The global positioning system, approaches with LNAV/ Position information is beyond the current capabilities of LNAV/VNAV (lateral navigation/vertical navigation)Įquipment is similar to ILS in that it provides both lateralĪnd vertical approach course guidance. Permit descent to a prescribed minimum descent altitude Provides lateral approach course guidance. LNAV (lateral navigation), like a conventional localizer,
