(8) Wait at least 20 seconds after the last disk has finished uploading. Then turn off the
PDL, remove power from the TT-- 950/951/952 Computer Unit, and disconnect the
interface cable.
(9) Apply power to the TT--950/951/952 Computer Unit and ensure the TCAS system is
fully operational. Push the PUSH TO TEST button located on the front panel. The
green LED indicator on the front of the panel lights at the end of the test cycle
(approximately 8 seconds) to show the TCAS system is functional.

Compact Flash Card -- TAWS/RWS Operational Software/ACD/ASDB Loading
(While Installed on Aircraft)
Due to the size of the TAWS/RWS operational software and database (in excess of 60
megabytes), the use of an ARINC 615 data loader is not feasible for TAWS/RWS
dataloading. As such, a high speed data loading method is provided using a Compact
PC Flash Card. The unit’s front panel has an access plate that allows a Compact PC
Flash Card to be inserted.
(1) Verify that the system inputs for AIR/GROUND (RMP--5K) and GEAR UP/DOWN
(RMP--13F) are grounded.
(2) Obtain the operational software and/or applicable TAWS/ACD/ASDB Database
(3) Apply power to the TT--950/951/952 Computer Unit.
(4) Insert the Compact Flash Card
NOTE: When a Compact Flash Card is inserted the T
2
CAS will blink the front panel
”XFER IN PROCESS” LED to indicate that a Compact Flash Card is
detected, but uploading or downloading has not begun.
(5) Once Software Upload has started the Dataload status will be indicated by the LEDs
on the front of the T
2
CAS Computer Unit. The LED correlations expected for the
various upload events are shown in Table 5-- 4.
(6) After Uploading has completed (Green CF Status LED), remove the Compact Flash
Card and the T
2
CAS will automatically restart.
