Ryan TCAD 9900 - Example Operation: Model 9900

53
EXAMPLES OF OPERATION, Model 9900
Power has been applied, and TCAD has completed the
initialization sequence. The altimeter setting can be entered
if desired.
In the illustration above, current altimeter is 30.14" and the
field elevation is 1,700 feet MSL. After a few seconds,
TCAD will enter a collision alert configuration (Search or
Threat Acquisition). The altimeter setting does not need to
be correct for effective collision alert operation, but it can be
very helpful (see Section V).
The shield sizes could be reset (see Appendix 1), but it is not
necessary to adjust them before each flight. For this
example, the shield sizes are those set at the factory (see
Appendix 3).
This illustration shows TCAD has automatically entered the
Ground Mode, and is operating in the Search Configuration.
All tones are muted (hence the "M") and aircraft at and
below 100 feet above the host encoded altitude are not
displayed (see Section III for more on Ground Mode).
