ATD-300 Traffic Warning Envelope

FAR Mode

When the left switch is in the mid position (FAR) the traffic voice warnings are initiated whenever traffic is within 3nm and less than ±1000ft of the host aircraft. The female voice will anunciate "Traffic". If the traffic or the host is not Mode C equipped the warning will be heard whenever the traffic is within 3nm irrelevant of the altitude difference.

NEAR Mode

When the left switch is in the upper position (NEAR) the traffic voice warnings are initiated whenever traffic is within 1nm and less than ±500ft of the host aircraft. The female voice will anunciate "Traffic Nearby". If the traffic or the host is not Mode C equipped the warning will be heard whenever the traffic is within 1nm irrelevant of the altitude difference.

MUTE Mode

MUTE deactivates all traffic warnings but not the voltage warnings. In the MUTE mode traffic altitude is shown as MSL altitude instead of relative altitude. This can be differentiated on the display by the lack of + or – symbol in front of the altitude number.

BRT Mode

When the right switch is set to the upper position the display is set to its maximun brightness. This mode is normally used during daylight flight.

DIM Mode

When the right switch is set to the mid position the display is set to its minimum brightness. This mode is normally used during night flight.
