1.2 PRODUCT DESCRIPTION
The Ryan TCAD (Traffic and Conflict Alert Device) is an on-board traffic display product
used to identify and display information regarding nearby transponder equipped aircraft.
Using Mode C and Mode S transponder replies, TCAD determines relative altitude and
range of nearby aircraft. Aircraft with non-Mode C transponders can provide range
information. The Ryan TCAD will not detect aircraft without transponders. TCAD,
within defined limits, creates a shield of airspace around the aircraft, whereby detected
traffic generates an alert. The shield size is selectable for various phases of flight. The
TCAD 9900B also provides bearing information.
TCAD uses a cockpit display for traffic information. Audible and visual annuciations are
provided to alert the pilot. Range is displayed in indicated Nautical Miles (iNM),
determined from the arrival amplitude of the threat transponder signal. Relative altitude is
displayed in hundreds of feet, and is determined from comparison of the threat aircraft
altitude replies with the host altitude encoder. Installation consists of single or dual
Display units, a remote mounted Processor, top and bottom mounted L-band antennas and
a Transponder Coupler for each transponder.
The Ryan TCAD 9900 Series consist of three models, the 9900, 9900A and 9900B. The
features below are provided. The table shows the availability of the features for each
model. See the Pilot's Handbook for limitations.
• Air Traffic Shield - Provides a shield of airspace above, below, and around your
aircraft.
• Traffic Display - Detects threats and displays altitude separation, and iNM (indicated
nautical miles) between your aircraft and threats.
• Trend Data - Shows trend between your aircraft location and the primary threat.
• Tone Alerts and Voice Alerts - Provides Voice or tone alerts for detected traffic.
• MSL Altitude, Mode A, and N-number - Capable of displaying additional data,
including MSL altitude, ATC Transponder Code (when available) and the N-Number
of U.S.-registered Mode S equipped aircraft.
• Host Altitude Display - Provides a digital display of altitude to crosscheck and
confirm your primary altimeter display.
