This chapter has the following sections:
• Basic check flow
• Pre-Installation Check
• Functional Test, on Ground
• Interference Test
• Functional test, airborne
6.1 Basic check flow
6.1.1 Check procedures
In order to ensure the correct function of the system, follow the below check flow.
1. Pre-Installation Check.
Perform this check after wiring, but before inserting the LRUs.
This is a check of the most important connections, the circuit breakers, cable losses etc.
Refer to Pre-Installation Check on page 6-2.
2. Configuration.
After performing the Pre-Installation Check, load the Secure ORT and the User ORT files.
Refer to Setup of the system on page 5-1.
3. Functional Test, on Ground.
When the system is configured and activated, make a functional test on ground. The
functional test should check all user interfaces, such as voice, data, annunciators, etc.
Refer to Functional Test, on Ground on page 6-3.
4. Interference Test.
After the functional test, make an interference test. This test is to verify that
transmission from the AVIATOR 200S system has no effect on the avionics of the
aircraft, particularly navigation equipment. Refer to Interference Test on page 6-4.
5. Functional Test, Airborne.
After the interference test, do a functional test while the aircraft is airborne. This test is
basically the same as the functional test on ground. Refer to Functional test, airborne
on page 6-5.
None of the check procedures described in this chapter can serve as a
replacement for any of the required approvals and certifications.
If additional avionics are installed in the aircraft at a later stage, repeat the
interference test to ensure compatibility.
