Installation Manual
•
The GPS signal may be blocked; move the aircraft to an open environment or
input a GPS signal using test equipment;
•
Check the GPS antenna or wiring for installation issues;
•
Check that the L-Band and GPS antenna cables are not swapped.
3. Compare the GPS position (lat/lon) to the aircraft’s actual position.
4. Note any other Alerts or Warnings that are displayed.
4.5.4 ADS-B Out Check
Before performing this check ensure that the GPS position is acquired and that no Failures or
Warnings are present.
1. Perform the ADS-B Out check per AC 20-165A using an IFR-6000 (or equivalent) Ramp
Test Set.
These tests should confirm the configuration settings made in paragraph 4.4 are correctly
transmitted in the ADS-B Out messages;
Several different Squawk Codes, including the pre-set VFR code should be checked;
Cycling the Mode through STB / GND / ON / ALT will verify their correct function.
4.5.5 Static System Check
1. After installation, a Static System test must be performed in accordance with 14 CFR
Part 91.411 and 14 CFR Part 43 Appendix E.
2. Verify that the displayed altitudes on the screen and the IFR-6000 are / 100 ft.
4.5.6 Electromagnetic Interference (E.M.I.) Check
Check the following applicable aircraft systems, as well as any other system or device that is not
listed, for interference. Tests should be conducted with the aircraft operating on external ground
power. Disregard any system or device that does not apply.
1. Communications
a. Cockpit Intercom
Using the cockpit intercom, verify interference free communications between the
crew while monitoring the effects of the KTX2.
VHF Communications
Set VHF communications radios to multiple frequencies and monitor effects of
KTX2 while transmitting and receiving. At a minimum, the frequencies listed
below should be tested, in addition to locally available frequencies:
NOTE
The Electromagnetic Interference Check is required
only for initial system installations and not required if
the unit is subsequently removed or replaced.
