Autopilot Flight Checks (if installed)
WARNING:
Remember to disconnect the Autopilot immediately if it is not performing its intended
function.
With wings level and the HDG Bug centered under the lubber line, deselect GPSS and engage
the autopilot in HDG Mode and ALT Hold Mode (if available). Verify that the aircraft makes no
abrupt turns during engagement and the aircraft continues to track straight.
a)
Now turn the HDG Bug 10 degrees to the right and verify the aircraft smoothly turns to
the right with a bank angle not exceeding 10 degrees. If 10 degrees was acceptable in
performance then proceed by turning the HDG Bug 90 degrees to the right and verify the
aircraft makes a standard rate turn and smoothly rolls out on to the correct Heading.
b)
Now repeat the test to the left.
c)
With VLOC1 selected (VOR1 source indication) and a VOR Station tuned. Adjust the CRS
pointer to center the CDI. Engage the autopilot in NAV Mode and verify the aircraft tracks
to the VOR.
d)
Enter a valid flight plan or Direct To on the GPS. Couple the GPS to the E5. Engage the
autopilot in NAV Mode, verify the autopilot tracks the GPS. (Note: GPSS is disabled for this
test, this test is verifying the GPS deviations to the autopilot)
e)
For GPS receivers using ARINC 429 interfaces, enable GPSS and engage the autopilot in
HDG Mode. Verify the autopilot tracks the GPS flight plan. Place the GPS into OBS (HOLD)
Mode (some GPS installations may require manual disabling of AUTOCRS). Use the CRS
Pointer on the E5 to steer the autopilot via the GPS. With the HDG Bug centered, press the
GPSS button again and verify the HDG Bug controls the autopilot as before.
f)
Perform an ILS approach using VLOC1 (ILS1 source indication). Verify that the autopilot
tracks the localizer, then captures and tracks the glideslope if installed.
g)
If your GPS supports GPS WAAS LPV approaches, perform an LPV approach using GPS1.
Verify that the autopilot tracks the GPS lateral approach guidance, then captures and
tracks the GPS LPV vertical guidance.
