TCAD 9900BX Menu Options

Altitude Option (Relative/Pressure)

The Altitude option lets you select between relative and pressure altitude in hundreds of feet. The Altitude op-
tion choice is shown in the upper left corner of the screen. Relative altitudes are shown with a "+" or "-", while
absolute altitudes are shown as just a number.

Filter

An altitude filter allows targets that are outside of a ±2000' vertical range to be filtered off the display.
The current mode is shown in the upper left corner of the display as "ALL" (no filtering) or "±2000" when the
filtering is active.

Volume

The volume of the TCAD voice alert can be adjusted by pressing the Volume button. This opens a text menu
where a value from 0 – 10 can be entered.

Approach Mode

The Approach Mode sends the approximate elevation of the destination airport to the TCAD unit for approach
mode operations. See the TCAD operator' s manual for additional details.

Ground/Flight Mode

The GND/FLT mode commands the TCAD unit into the corresponding mode. See the TCAD operator' s manual
for additional details.
