10. Aircraft Maintenance Programs
A. General
The maintenance procedures for TCAS are recorded in FAA Advisory Circular AC 120-55, Air
Carrier Operational Approval and Use of CAS-100. These procedures include the initial start
or return-to service, TCAS-related maintenance records, maintenance training, and other
maintenance program responsibilities. Also included in this advisory circular are approaches
to get FAA approval to use TCAS in the operations, including airworthiness approval,
operational approval, approval procedures, and other serviceable issues.

B. Honeywell TCAS Maintenance Recommendations
The Honeywell CAS-100 system is for ON CONDITION maintenance. Automatic performance
monitoring and self-test are continuously performed by the TPA-100A TCAS Processor BITE
to find the malfunctions that decrease or prevent TCAS protection to a high degree of
confidence. When correctly installed and interfaced with approved aircraft signal sources, it
meets or exceeds the FAA System Safety Analyses about the probability of an unmonitored
incorrect Resolution Advisory on the order of 1.0 in 100,000 in the route, and 1.0 in 10,000 in
the terminal area.

Further approval of satisfactory operation of visual displays and aural annunciations can be
determined by periodic operation of the manual self-test function as set by the mode selector
switch on the Mode S/TCAS control unit. Refer to paragraph 2.B. in the TESTING AND FAULT
ISOLATION section of this manual for a description of the functional test sequence and
permitted indications during self-test.

After major aircraft maintenance cycles, additional system operations must be checked with a
TCAS Ramp Test Set with which directional antenna accuracy measurements to the standards
of FAA Advisory Circular AC 20-131A (or later revisions) can be performed; or in accordance
with the Operator's Approved Maintenance Program.

Table 2008 through Table 2017 for the IVA-81( ) Configuration Matrix.
