When the Bore Sight procedure is successfully completed, the Delta 1 and
Delta 2 offsets for the selected antenna will be stored in the configuration
module.
TAS will automatically shut down and restart after the procedure has been
completed to begin using the new antenna offsets.
After the Bore Sight Procedure has successfully completed, The Bearing
Accuracy Test (E 10) should be re-run at + 30° , 0° and -30° to confirm
that the bore sight procedure has improved bearing accuracy.
12. Perform the Power and Frequency tests shown in the TCAS-201 Oper-
ator's Guide (pp 27- 29). These tests are optional.
13. Perform Electromagnetic Interference (EMI) / Radio Frequency
Interference (RFI) required for STC. Determine if there is any mutual
interference with any other aircraft system.
Pass/Fail ______.
14. Determine that the system suppression is active.
15. Conduct a flight test of TAS (Required for STC) according to the
requirements of FAA Advisory Circular AC 20-ZZZ, titled "Airworthi-
ness Approval and Operational Use of Active Traffic Advisory System
(TAS)".

D. "Bore Sight Failed. Not enough replies are being received."
This error will be reported when at least 30 Delta 1 and 2/swap A
and B replies are not received. Check Ramp Tester operation and
placement and retry the procedure.
E. "Bore Sight Failed. The Antenna calculations could not be written
to the configuration module."
This error will be reported if the bore sight procedure completes, but
the antenna Delta offsets cannot be saved to the configuration mod-
ule. Check the wiring and the connection to the configuration module
and retry the procedure. or try re-initializing the configuration mod-
ule and retry the procedure.
