MON ATD-300	Air Traffic Detector, ATD-300, Monroy	ADD	$595.00

The ATD-300 Traffic-Watch provides multiple capabilities that enhance the safety of flight. Among them:

• Traffic relative altitude readout
• Traffic MSL Altitude
• Traffic Range up to 5nm
• Host transponder altitude/code readout
• Voltage Indication
• High/Low Voltage alarm
• Bright LED 8 character dot metrix display
• Auto Mode Display
• ATD-200 Interchageable (same size (2.75"w x 0.75" h x 5.0" d) and connections)
• Portable and Installed configuration
• Voice Annunciation of traffic
• 3 Year Factory Warranty

The ATD-300 Traffic-Watch is a passive receiver capable of detecting transponder replies from nearby aircraft and displaying their range and altitude on a bright 8-character dot matrix yellow LED display. It also provides distinctive voice warnings in relation to traffic proximity. The ATD-300 has a detection range of 5 nautical miles. The system consists of a receive/indicator unit, antenna, power cord and headphone cable. The receiver is housed in a small aluminum box (2.75" x 0.75" x 5.0") for easy location in the cockpit.

The ATD-300 provides distinctive voice warnings for traffic at different ranges. When set in the FAR mode and traffic is within 3nm and +- 1,000ft of vertical separation "Traffic" will be annunciated. As the traffic gets closer to about 1nm and within +- 500ft of vertical separation will be annunciated by "Traffic Nearby". When set to MUTE there is no warning messages for any traffic, however traffic range and pressure altitude will still be indicated. When there is no traffic activity the ATD-300 will automatically indicate the host transponder MSL pressure altitude. A screwdriver adjustable volume control is located on the bottom side of the unit. Audio output to a speaker (8 ohms) or headphones (300 ohms) is provided on the rear of the unit.

Unlike traditional active TCAS systems the ATD-300 determine traffic's range by its signal magnitude. Although not as accurate, this method allows for a compact low cost unit with a higher reliability than traditional active TCAS transmitters.

The ATD-300 uses the onboard transmitted transponder altitude encoder data and the traffic's encoder data for relative altitude indication. Because these FAA-TSOd encoders are checked every two years, it assures that the indicated differential altitude is as accurate as the received by ATC. Since the ATD-300 has no internal altitude sensor, there is no need for periodic calibration checks or static port connections, particularly in pressurized aircraft. Thus making the unit easily portable between pressurized and non-pressurized aircraft.

In areas of high traffic activity the display will show multiple traffics in an alternating fashion. This is most common for traffic between 4 and 5nm. Display preference is given to the closest traffic by distance and altitude. As traffic gets closer, background traffic display is reduced or eliminated.

The ATD-300 also features a built-in voltage-warning indicator that lets you know if the aircraft supply voltage is out of range. This function works in the background at all the times and is activated after engine start. If an out of range condition exists, the ATD-300 annunciates it by voice and by text.

Monroy ATD-200

Part No.	Description	CART	Price
MON ATD-200	Air Traffic Detector, Monroy Aerospace	ADD	$575.00

The Monroy ATD-200 is an Air Traffic Detector. Using a passive receiver to detect transponder replies from nearby aircraft, it displays their proximity in a segmented graphic LED display. It also provides distinctive voice alerts in relation to traffic proximity. The system consists of a receiver/indicator unit, detachable antenna, cigarette adapter power cable and headset audio cables. It is housed in a compact aluminum box (2.75" x 0.75" x 5.0") for easy placement in the cockpit.

The ATD-200 has a light aircraft detection range of 5 nautical miles and up to 7 nautical miles for air transport aircraft flying within 1500 ft vertical separation. Red bar graph lights one LED at 5 NM progressively to all five lite at 0.5 NM No need to interpret numbers, the more red you see, the closer the threat is. Mode "S" or TCAS II (airlines) equipped aircraft are indicated by the yellow LED indicator.

Voice annunciations are as follows:

• At a traffic range of 3 NM the ATD-200 female voice annunciates, "TRAFFIC"
• At a traffic range of 1 NM or closer, it annunciates "TRAFFIC NEARBY"
• Voice Alert may be set to alert for NEAR range only (1 NM or closer)
• Voice Alert may be muted for high traffic density environments

May be attached to an external antenna and speaker.

Features:

Detects all transponder equipped traffic Bright graphic display of traffic range 5 NM detection range Mode S indicator Selectable range Voice Alert Multiple voice messages Voice output to speaker or headphones Plug n'Fly, no installation required

Works with internal or external antenna One compact box (2.75"w x 0.75"h x 5.0"d) Can be velcro or panel mounted Operates on 11-28Vdc On-board transponder test mode Display dimmer 3 year warranty
