J. Now press function key F6 on your keyboard.
K. Set the aircraft's altimeter to 29.92 IN Hg and note the altitude displayed on
the altimeter. Now look at the PC screen and locate the item named Gill-
ham Alt ft. and verify that the altitude shown agrees with the aircraft altime-
ter, ± 100 feet. If it does not, troubleshoot the encoding altimeter / wiring.
L. Provide a source of GPS signals to the GPS antenna. This can be accom-
plished by using a GPS repeater inside a hanger, or by taking the aircraft
outside where it has a clear view of the sky.
M. Press function key F6 to return to the command mode of WinsViews. Type
in GPS followed by the 'Return' key to view the status of the GPS receiver.
Typing control 'R' on the keyboard will re-issue the last command sent and
allow you to continue to monitor GPS status. Once the GPS has acquired
satellites, the status message "Not Navigating" will change to "Navigation
with possible data collection". The Not Available Lamp should turn off and if
a display is being used, a North UP terrain view should be shown on the
display.
N. Press the 'Self Test' switch and verify that the unit lights all lamps, produces
audio and the display, if installed, shows a test pattern. The EGPWS self
test function will identify any problems with the interfaces or with the
EGPWS computer. Troubleshoot any problem reported during the self test.
O. Connect a pitot-static test set to the aircraft static system. Operation of the
pitot-static test set should be performed only by persons trained in its use.
Additionally, if the aircraft static system was opened or modified to add an
encoder, the static system must be tested and approved by a licensed
mechanic or authorized repairman. Improper use of the pitot-static test set
can result in damage to altimeters, vertical speed indicators, etc.
P . Start with the pitot-static test set at current field elevation. Set the reference
altimeter in the test set for 29.92 IN. Hg.
Q. On the PC, select the Data display mode (F6). With the system receiving
GPS signals and no faults reported, you should now verify that the system
has correctly identified your closest airport. Look at the following items on
the PC display:
CrwyApt
CRwyDist nm
