Section 4

Ryan TCAD Interface

To change the Barometric Pressure:

From the Traffic Page, press the cursor to

highlight the Operating Mode field. Turn the

large right knob to select the Barometric

Pressure Field. Use the small right knob to

select the desired value and press ENT. Note:

When editing the value, use the large right

knob to select the digit to edit.

Exit the field by pressing the CRSR button.

When the TCAD 9900BX model is interfaced

there is an additional annunciation in the lower left

hand corner of the Traffic Page. This indicates when

the TCAD unit is in approach mode (APR), or if the

approach is armed (APR ARM).

Air Shield

Please refer to the TCAD Pilot' s Handbook for a

detailed description of the Air Shield.

Traffic Warning Window

When the Traffic page is not displayed and a

traffic threat becomes imminent, the Traffic Warning

Window will be displayed. The Warning Window

shows a small map and can display the Traffic Page (if

the user presses ENT) or return to the previous page

(if the user presses CLR).

Ryan TCAD Traffic Warning Window

NOTE: The Traffic Warning Window is disabled when

the aircraft ground speed is less than 30 knots or when

an approach is active.

Threat Acquisition

Please, see the TCAD Pilot' s Handbook.

Audible and Visible Alerts

Voice and tones are used to alert the pilot. The alert

descriptions used by TCAD are listed in the TCAD

Pilot' s Handbook. Voice is used only during the high-

est level of alerting; otherwise, tone is used. The voice

alerting can be turned on or off either on the TCAD

Setup Page or on the configuration pages. See the

Garmin 400W/500W Series Installation Manual avail-

able at your authorized Garmin Service Center (only

for the 9900 model).

Fault Displays

If the 400W/500W Series unit fails to detect the

Ryan TCAD or if it detects invalid data from the

TCAD, the traffic screen will display the message, "NO

DATA".

Limitations

Please see the TCAD Pilot' s Handbook for limita-

tions of the TCAD system.
