As you approach the FAF, a "Right to 214° in x sec" waypoint alert appears in the lower right corner of the screen. 95 5 - PROCEDURES Vectors-To-Final Approach 11. As you approach the MAP, a waypoint alert ("Arriving at waypoint") appears in the lower right corner of the screen. CDI scaling continues to tighten from 0. 3 NM to 350 feet, full-scale deflection. Vectors to Final Let's take a second look at the "VOR 22" approach into Billard Municipal. Instead of following the DME arc, ATC tells you to expect vectors onto the final approach course. There are several ways to select "vectors to final" with the 500W-series unit. The first two options below normally require the least workload to accomplish: · When the approach is first selected, choose "VECTORS" from the transitions ("TRANS") window. · Load a full approach -- including the IAF from the transitions window. When cleared, press PROC and select "Activate Vectors-To-Final?". As you approach the MAP, an "Arriving at waypoint" alert appears in the lower right corner of the screen. · Load the full approach. Use the direct-to key (by pressing it twice) from the Active Flight Plan Page to select the desired leg of the approach. To select "VECTORS" from the transitions window: 12. As you cross the MAP, "SUSP" appears above the OBS key, indicating that automatic sequencing of approach waypoints is suspended at the MAP. A "from" indication is displayed on the CDI and Default NAV Page, but course guidance along the final approach course continues. Follow published missed approach procedures using the OBS key to initiate the missed approach sequence. 1. Select Billard Muni (KTOP) as your destination, using the direct-to key, or as the last waypoint in a flight plan. 3. Select "VECTORS" from the transitions window to activate only the final approach course. 96 5 - PROCEDURES Vectors-To-Final Approach 4. Select "Load?" (or "Activate?", if already on vectors-to-final). Flying the Vectors Approach To activate vectors-to-final from the procedures page: 1. Select Billard Muni (KTOP) as your destination, using the direct-to key or as the last waypoint in a flight plan. From the transitions window, select "D258G/ LEBVY" as the IAF. Also, select "Load?". NOTE: Since this is not a GPS approach, the pilot should be using the VLOC receiver, tuned to the correct VOR (TOP) for navigation. 2. 3. With "Vectors-To-Final" (VTF) selected, the CDI needle remains off center until you're established on the final approach course. With the approach activated, the Map Page displays an extension of the final approach course in magenta (remember, magenta is used to depict the active leg of the flight plan) and "VTF" appears as part of the active leg on the Default NAV Page (as a reminder that the approach was activated with vectors-to-final). In this example, we'll assume ATC vectors result in a rectangular course to intercept final, as follows: DO NOT USE FOR NAVIGATION 4. When cleared, press the PROC key and select "Activate Vectors-To-Final?". Press PROC and select "Activate VectorsTo-Final?" to activate only the final course segment of a loaded approach. 1. When VTF is activated, the 500W-series unit switches from en route mode to terminal mode and the CDI scale transitions from 2. 0 to 1. 0 nautical miles, full scale deflection. 97 5 - PROCEDURES Vectors-To-Final Approach 2. If you haven't already done so, activate the approach (with vectors-to-final). This allows the 500W-series unit to guide you to the final approach course. As you converge with the final approach course, the CDI needle (on the Default NAV Page and the external CDI) moves toward the center. 6. If the approach is loaded, but not yet activated, press PROC and select "Activate Vectors-To-Final?". 3. ATC instructs you to turn left to a heading of 025°. This places you parallel to the final approach course in the opposite direction. ATC instructs you to turn right to a heading of 175° to intercept the final approach course. [. . . ] If you are in a missed approach situation and would like to return the CDI to the 1. 0 NM scale, activate the missed approach sequence by pressing the OBS key after you pass the MAP and the annunciation in the lower left of the screen changes from MAPR to TERM, as described in Section 5 - Procedures - Flying the Missed Approach. For this to occur however, the course to the MAHP must be greater than 3° away from the course line to the runway. The CDI scale is also 1. 0 NM (terminal mode) within 31 NM of the departure airport. Full-Scale deflection and defined path for normal approach Origin = 10, 000 ft past MAP FAF Inbound track to FAF +350 ft ±2 degree angular Full-Scale deflection and defined path for VTF approach MAP ±1 NM Sensitivity must change from ±1 NM FSD to either ±0. 3 NM or ±2° FSD, whichever is less at the FAF. Why does my CDI not respond like a VOR when OBS mode is active? Unlike a VOR, the CDI scale used on GPS equipment is based on the cross-track distance to the desired course in OBS mode, not an angular relationship to the destination. [. . . ]
