TCAD – Traffic Collision Avoidance Device

Air Traffic Warning for early recognition of dangerous situations
– your window through the clouds

TCAD – Traffic Collision Avoidance Device

Pilots permanently watch the airspace, however, without aiding instruments critical situations may appear

"One is often surprised how close traffic already is once it becomes visual." says Steffen Keppler, ATP pilot
with more than 1.500 flying hours.

Systems for traffic warning are an almost irreplaceable aid here: the air traffic appears with coloured symbols -
corresponding to the danger intension - at the Multi-Function-Display. This saves valuable seconds in
the critical moment.

MT TCAS: Darstellung von Avidyne, FLARM / FLOICE oder ZAON Signalen

Strong combination – display of MT TCAD (Ryan/Avidyne TAS 600 series) and FLARM/FLOICE-signals
at a highly efficient MFD at the same time. The display of ZAON signals is also possible.

Reduction of Workload in the Cockpit

  • Direction and speed of oncoming traffic is immediately visible at the screen, the pilot does not need to reserve attention to monitor other instruments.
  • There is more time for airspace observation and other pilot duties.
  • All information at one display: on your Moving Terrain Multi Function Display - which has further options to offer you safety during your flight.


MT-TCAD: Advantages

  • Display of surrounding traffic with SQUAWK.
  • Blinking aircraft symbols for optimum visibility on the Moving Map.
  • Colour coded aircraft symbols (no conventional diamonds).
  • Enhanced information (speed, direction, relative height, trend) at a glance.

The "Critical Cylinder" – Your Wall of Safety

Der kritische Zylinder

MT TCAS - größere Höhe

Higher than the „critical cylinder“ (in relation to your own aircraft)
MT TCAS - gleiche Höhe Within the „critical cylinder“, distance and direction outside the danger zone
MT TCAS - gefährliche Nähe Within the „critical cylinder“, dangerously close
MT TCAS - geringere Höhe

Lower than the „critical cylinder“

The Dynamic Synchronized Simulation (DSS) technology: simulation of direction and trend

  • As soon as a target is located in the area a simulator is activated, the traffic performance is analyzed and the simulator is calibrated accordingly. The motion of the aircraft becomes extracted from that simulation and immediately visualized. Thus the pilot is immediately able to recognize speed, direction and the resulting threat at a glance at the MT - MFD.
  • Every single aircraft is identified by the sensor and evaluated by the MT-system. This creates a very clear picture of traffic in the air space.
  • Display of
    • approach speed
    • flight direction
    • relative hight of the own aircraft
    • tendency (climb- and descend rate)

Visualization of Traffic

MT TCAD can be visualized either in the MFD mode or superimposed over a (terrain) chart. The latter yields a perspective of the target´s position with respect to ground references and not only abstract with ...o`clock .... miles  –  a further Moving Terrain safety plus.

MFD mode (without map)

Laid over the Moving Map

MT TCAS überlagert auf originalen Flugkarten

  • Blinking aircraft: optimum visibility.
  • Indication of the relative height with regard to the own aircraft (in 100 ft).
  • Red arrow: climbs / descends faster than 500 fpm.
  • The speed vector: plots 15 seconds ahead and allows conclusions on the category of aircraft.
  • Projection over the Moving Map: air traffic is displayed with respect to the terrain and thus a fast identification is possible, much faster than „Your traffic is 10 o‘clock, 3 miles“.
  • The pilot becomes aware of the nearby traffic while at the same time concentrating on something else.
