As GPSS completes the procedure turn and rolls out centered on our nal approach
course of 164°, we begin a descent down to 8,500 feet, which we will maintain until
glideslope intercept.
1. Press the Right Knob twice to select ALT for editing.
2. Turn the Right Knob to set 8,500 as our Selected Altitude.
3. On reaching 8,500, re-engage ALT hold on the autopilot.
We are still navigating along the ILS16R approach using GPS, with GPSS driving the
autopilot in HDG mode. We know we’ll have to switch the autopilot to APPR mode
before glideslope intercept in order for the autopilot to capture the glideslope and y
us down the ILS. But we’ll continue in GPSS and HDG mode a while longer because it
tracks the course more accurately with our aging autopilot.
Along this intermediate segment of the approach, watch for the 430W to switch
automatically from GPS to VLOC output on its CDI.
• Watch for the PFD CDI Source Select eld to change from GPS1 toVLOC1.
This automatic switch from GPS to VLOC should occur 2–10nm outside the Final
Approach Fix (FAF). If it has not occurred automatically by 2nm outside the FAF,
manually press the CDI Button on the 430W to make the switch to the ILS frequency,
and the PFD will follow by switching its Navigation Source Select to VLOC1.
As the PFD navigation source switches to the ILS on VLOC1, the LDI and VDI (Figure
2-2, Refs. 36 and 37) will appear on the Attitude Display.
1. The LDI Navigation Source Indication (Figure 2-2, Ref. 31) will show ILS, if
it is receiving a valid glide slope signal, or LOC, if it is not receiving the glide
slope (GS).
2. The CDI Source Information Block (Figure 2-2, Ref. 65) will also show ILS
orLOC.
