3. Click on the Restart Unit button.
4. The unit starts up in normal operation, with an amber "Ground Test" message shown below the
options button on the right side of the display.
• Cycling power at any time takes the unit out of Ground Test Mode. (Note: Ground Test Mode is
automatically, without cycling power, exited if aircraft flight is detected).)
5. Continue with the checkout procedures below.
The Panel Mount NGT-9000 may alternately use the touch display to place the unit in Ground Test.
This is done by first placing the unit in Maintenance Mode per paragraph 3.5 and selecting “Reboot>”
and then “Ground Test>”. The unit will start up in normal operation, with an amber "Ground Test"
message shown below the options button on the right side of the display.
NOTE
There is no prompt for Simulated Own Direction in this mode. The unit
will default to a North Up track, which may differ from the real time true
heading. In the Panel Mount Ground Test mode therefore, a “Cross
Check Heading” message may be seen.
This message can be ignored if the following precautions are taken (IFR-
6000 ramp tester example):
• The default 0 degree track angle should be set on the IFR-6000
UUT HDG entry field when testing ADS-B GEN entries on the
IFR-6000
• The current heading should be set on the IFR-6000 UUT HDG
when testing TCAS intruders on the IFR-6000. If there is no current
heading source, the default 0 degree track angle should be set on the
IFR-6000 UUT HDG entry field.
If there is no heading input or heading is inactive to the Lynx NGT-9000, then select Ground Test and
enter a Simulated Own Direction (0 – 359 deg.). The own direction entry should be set to the current true
heading of the aircraft. A unit with a heading input must have an entry of the current heading, so that
track and heading are in agreement.
1. When entering heading information into the IFR-6000 UUT HDG entry field make sure to enter one
of the following:
• If there is no heading input or heading is inactive, the same simulated heading as was entered
into the MPC (MAT) own direction field should be set in the UUT HDG field
• If there is a heading source, the actual aircraft heading (true heading) should be set in the UUT
HDG field.
3.11.2.2 Altitude Check
1. Perform the altitude check per 14 CFR Part 91.411 and 14 CFR Part 43 Appendix E & F.
2. Verify that the displayed altitudes of the panel mount NGT-9000 or alternate display or CP-2500 and
the primary display (PFD) or equivalent instrument are within the required range shown below (per
the installation):
• Gillham Code altitude source the range is +/- 100 ft.
• Other altitude source the range is +/- 25 ft.
