ADS-B Out is the broadcast part of ADS-B. An aircraft equipped with ADS-B Out capability will continuously transmit aircraft data such as airspeed, altitude, and location to ADS-B ground stations. ADS-B In is the receiver part of the system. ADS-B In equipment allows aircraft, when equipped properly, to receive and interpret other participating aircraft's ADS-B Out data on a computer screen or an Electronic Flight Bag in the cockpit. TIS-B is short for Traffic Information Service-Broadcast. No subscription service or added fees are associated with TIS-B. FIS-B, short for Flight Information Services-Broadcast, can be received only through the 978 MHz UAT structure.

ADS-B Automated Dependent Surveillance - Broadcast

ADS-B Out ADS-B Out is the broadcast part of ADS-B. Aircraft with ADS-B Out will continuously transmit aircraft data (airspeed, altitude, and location) to other aircraft and the ground. To meet the year 2020 FAA ADS-B Mandate, You must have a system that provides ADSB OUT to fly freely in Certain Airspace requiring a Transponder. After Jan. 1, 2020, most aircraft will be required to have at least ADS-B Out capability. The minimum equipment needed for ADS-B Out capability includes an ADS-B-approved transmitter—either a 1090 MHz Mode S transponder (Like the Garmin GTX 345) or a dedicated 978 MHz UAT for use with a previously installed Mode C or Mode S transponder—and a WAAS-enabled GPS system.

ADS-B In is the receiver part of the system. ADS-B In equipment allows aircraft, when equipped properly, to receive and interpret other participating aircraft's ADS-B Out data on a computer screen or an Electronic Flight Bag in the cockpit. The ADS-B In function requires an approved ADS-B Out system, along with a dedicated ADS-B receiver that has "in" capability. For CAP this is Satisfied with the GARMIN GTX 345 installation. Additionally, an ADS-B compatible display interface will be needed for graphic weather and traffic displays (called TIS-B and FIS-B) For CAP, this can be a G-1000, or GTN-600 Series touch screen GPS.

GARMIN GTX 345 Transponder For CAP Aircraft

The CAP Solution for ADSB in and Out is the GARMIN GTX Transponder. The GTX 345 ADS-B receiver is a dual-link system. So, it can receive on both frequencies (978 MHz and 1090 MHz) authorized for ADS-B operations in the U.S. Not only does this provide the most complete traffic picture from aircraft transmitting on either frequency, but it also enhances your aircraft’s ability to access ADS-B transmissions and services from virtually anywhere. When integrating an active traffic system with the GTX 345, ADS-B traffic and active traffic targets are merged on the display to give pilots a truly comprehensive traffic picture.

Enroute Radar (Used by Center Controllers) makes a complete revolution around every 12 Seconds Terminal Radar (Used by Approach Controllers) revolves around every 4 Seconds.

Moving to an Update EVERY SECOND, greatly increases ATC awareness

Faster Updates from ADS-B Aircraft allow better Control and Separation Service by ATC.

YES –All CAP Aircraft equipped with the GTX 345 ADS-B receiver will receive Traffic directly from ADSB Compliant Aircraft - regardless if that Aircraft is transmitting on 978MHz (For the US) or 1090 MHz. Since the GTX 345 is a dual-link system, it can receive on both frequencies (978 MHz and 1090 MHz) authorized for ADS-B operations in the U.S. Not only does this provide the most complete traffic picture from aircraft transmitting on either frequency, but it also enhances your aircraft’s ability to access ADS-B transmissions and services from virtually anywhere.

ADS-B Traffic TIS-B

TIS-B is short for Traffic Information Service-Broadcast. TIS-B services will work with both the 1090 MHz Mode S transponder and the 978 MHz UAT systems. No subscription service or added fees are associated with TIS-B. A 1090 MHz Mode S transponder is required for aircraft flying at 18,000 feet and higher and is the standard in Europe. A 978 MHz UAT is primarily marketed to general aviation pilots, as it can only be used below 18,000 feet and in the United States.

EVERYONE Reports to the Ground. HOWEVER; your ADS-B compliant Aircraft will also receive traffic reports (TIS-B) Directly from ADS-B Compliant Aircraft

Since EVERYONE Reports to the Ground (Both Compliant and Non-Compliant Aircraft with a Transponder), your ADS-B compliant Aircraft will also receive traffic reports (TIS-B) Broadcast Directly from ADS-B Stations on the Ground, reflecting what the Controllers are seeing on their Screens.

To Accomplish that, the ADS-B system will provide a packet of traffic in the form of a “Moving Puck” around your aircraft, again, reflecting what the Controllers are seeing on their Screens.

TIS-B packet of Traffic will be sent to the GTX 345 via a 978 MHz UAT systems in the United States. No subscription service or added fees are associated with TIS-B.

ADS-B Weather – FIS-B

FIS-B, short for Flight Information Services-Broadcast, can be received only through the 978 MHz UAT structure. It's also free to anyone with a 978 UAT. A 1090 MHz Mode S transponder is required for aircraft flying at 18,000 feet and higher and is the standard in Europe. A 978 MHz UAT is primarily marketed to general aviation pilots, as it can only be used below 18,000 feet and in the United States.

In addition to 1090 MHz ADS-B “Out”, the GTX 345 also makes available the subscription-free weather and traffic display capabilities enabled by ADS-B “In” — which can be interfaced with compatible cockpit displays or streamed wirelessly via Garmin Connext to our aera 796/795 and aera 660 series portables, as well as to tablets/mobile devices by way of the Garmin Pilot™, ForeFlight Mobile or FltPlan Go apps. The ADS-B weather link is continuously broadcast on the 978 MHz Universal Access Transceiver (UAT) frequency, and is similar to the basic services offered by leading commercial satellite weather providers. For example, you can access NEXRAD imagery, METARs, TAFs, winds and temperatures aloft, PIREPs, NOTAMs, and more1: Along with this, you can also receive ADS-B traffic position reports (and threat-level symbology) to help you see-and-avoid converging targets in busy airspace. Spoken audio alerts call out potential flight path conflicts (“Traffic, 10 O’Clock, same altitude, two miles”) to get you looking in the right direction. Meanwhile, on your display, Garmin’s patented TargetTrend™ relative motion display¹ offers a faster, more intuitive way of judging target trajectories and closure rates in relation to your flight path.

GARMIN GTX 345 Transponder For CAP Aircraft

ADS-B Weather in the Cockpit is Strictly for STRATEGIC WEATHER PLANNING – Not for Tactical Weather Avoidance!! RADAR Delays are usally 20 Min or Longer!! Choices should ONLY be to Turn Around (avoid) , Fly Well Clear, or LAND.

GARMIN GTX 345 Transponder For CAP Aircraft

The CAP Solution for ADSB in and Out is the GARMIN GTX Transponder. Since the GTX 345 ADS-B receiver is a dual-link system, it can receive on both frequencies (978 MHz and 1090 MHz) authorized for ADS-B operations in the U.S. The addition of 1090 MHz ADS-B “Out” transmission capability (using precise GPS-referenced positioning information) enables the transponder to automatically output the more accurate, more dynamic traffic surveillance data that the NextGen airspace system requires. Plus, available ADS-B “In” reception unlocks even more capabilities for pilots, enabling them to display ADS-B traffic, weather and more on a variety of installed or portable displays.
