As you cross the FAF, the destination sequences to the MAP ("RW22"). With the needle centered, fly toward the MAP, observing the altitude minimums dictated by the approach plate. As you approach the MAP, a waypoint alert ("ARRIVE WPT") appears in the lower right corner. 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. Course From Fix Flight Plan Legs 8. 7. DO NOT USE FOR NAVIGATION As you approach the FAF, a waypoint alert in the lower right corner ("RT TO 214° x S") will appear. Make any course adjustments necessary for the final course segment (FAF to MAP). Certain approach, departure, and arrival procedures in the Jeppesen database contain course from fix flight plan legs. The 400W-series is able to load these legs into the flight plan along with the rest of the procedure data, and to provide navigation along these legs. There are three different types of course from fix legs: TYPE 1: Course from fix to distance, or Course from fix to DME distance Course from fix to distance legs will appear in the flight plan like normal waypoints, but the destination name will always begin with a "D", followed by a distance in tenths of nautical miles from the waypoint fix. This example uses the VOR/DME RWY 25 approach into Palmdale, California (KPMD) and includes a teardrop course reversal. 98 5 - PROCEDURES Course-From-Fix Legs Palmdale (CA) AF Plant 42 VOR/DME or GPS Rwy 25 flight plan will automatically sequence to the next leg upon reaching "D13. 0". DO NOT USE FOR NAVIGATION 3. At 13. 0 NM from the IAF, a waypoint alert ("DTK 265° x S") will appear in the lower right corner of the screen. Make a standard rate turn to the right to intercept the final approach course and watch for the CDI needle to begin to center. As you approach the intermediate fix (CF25), a waypoint alert ("DTK 265° x S") will appear. Approach is active when the FAF is the TO waypoint and bearing and track are within 45° of the final approach course. ("LNAV" will appear in the lower left corner of the screen--replacing "TERM". ) CDI scaling will be tightened from 1. 0 to 0. 3 nautical mile full scale deflection, or 2° full scale deflection, whichever is less at the FAF, and as defined for the approach. As you approach the FAF, "DTK 265° x S" will appear in the lower right corner of the screen. With the CDI needle centered, fly toward the MAP, observing the altitude minimums dictated by the approach 99 4. 5. As you reach the initial approach fix (PMD), a waypoint alert ("RT TO 070° x S") will appear in the lower right corner of the screen. As the distance to the IAF approaches zero, the alert is replaced by a turn advisory ("RT TO 070° NOW"). Dial the outbound course into the CDI (or HSI) using the OBS knob and initiate a standard rate turn to this course heading. You are now on the "course from fix to distance" leg, as shown on the active flight plan and default NAV pages. Note the magenta line in the bottom figure, which represents the currently active leg of the 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. If you do not have an HSI, you should make your course selections on the external CDI's OBS knob and the DG heading bug. When does turn anticipation begin, and what bank angle is expected? The 400W-series unit will smooth adjacent leg transitions based upon a nominal 15º bank angle (with the ability to increase the bank angle up to 30º) and provide three pilot cues for turn anticipation: 1) A waypoint alert ("LT or RT to ###° x S") will flash in the lower right corner of the screen 10 seconds before the turn point. 2) A flashing turn advisory ("LT or RT TO ###° NOW") will appear in the lower right corner of the screen 195 APPENDIX C Troubleshooting Q & A 11 nm nm 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 2 nm 2 nm 2 nm 2 nm Sensitivity must change from ±1 NM FSD to either ±0. 3 NM or ±2° FSD, whichever is less at the FAF.
