SECTION 9
SUPPLEMENT 20 PA-28-181, ARCHER III
REPORT: VB-1611 ISSUED: JULY 12, 1995
9-134, 26 of 30 REVISED: JANUARY 9, 2006
SECTION 7 - DESCRIPTION AND OPERATION (continued)
A. PFD Systems Description (continued)
Autopilot Integration (continued)
The following autopilot modes are supported by the PFD:
1. HDG (Heading, using the heading bug)
2. NAV (Nav, using the course pointer and course deviation indicator)
3. GPSS (GPS Steering, using GPS course guidance)
4. APR (Approach, using the HDI and VDI, including automatic glide
slope capture)
5. REV (Reverse sensing HDI approach)
6. ALT (Altitude Hold and Preselect, using the altitude bug)
7. VS (Vertical Speed, using the vertical speed bug)
NOTE
When HDG mode is engaged, rotation of the heading bug
greater than 180° will result in a reversal of turn direction.
CAUTION
If a VLOC is selected in NAV on the PFD and GPSS
mode is engaged on the autopilot, the autopilot will track
the active flight plan in GPS1 if VLOC1 is selected or
GPS2 if VLOC2 is selected and not track VLOC1 or
VLOC2 as the selected source in NAV on the PFD.
Therefore, the course deviation on the PFD CDI and the
course deviation flown by the autopilot can be different.
This situation may be confusing and should be avoided.
Engine Instruments
The Entegra PFD provides a display of Engine Tachometer (RPM), Oil
Pressure (OP), and Fuel Flow (FF) in the upper left hand corner of the display.
Tach indications are presented on analog scales with normal operating (green)
and warning (red) markings, as appropriate. A digital indication presents fuel
flow information in gallons per hour (GPH). A digital indication presents oil
pressure information in pounds per square inch (PSI).
