ADS-B Notes

ADS-B

Automatic Dependent Surveillance-Broadcast(ADS-B) is an acronym for:

•Automatic - It's alwaysONand requires no identing or interogation

•Dependent - It depends on an accurate GNSS signal for position data and other aircraft being properly equipped.

•Surveillance-It provides "Radar-like" surveillance services, much like RADAR

•Broadcast - It continuously broadcasts aircraft position and other data to any aircraft, or ground station equipped to receive ADS-B

Mandate, Jan 1, 2020 for ADS-B OUT

ADS-B OUT required if you operate in:

•Class A airspace

•Class B airspace (within 30 nm veil)

•In & Above Class C airspace

•Above 10,000’ MSL (excludes airspace below 2,500 AGL)

ADS-B IN allows the pilot to receive a weather and traffic display in the cockpit. The display can be either superimposed on a Garmin 430/530 screen, or on an iPad.

ADS-B Progress:

ADS-B IN traffic

Every time your ADS-B transponder, whether it’s a 1090 MHz Extended Squitter transponder or a 978 MHz UAT sends a position report to an ADS-B ground station, that position report prompts the ground station to send you traffic information services (TIS-B) - a customized traffic package, called a “Hockey Puck”. In this “Hockey Puck”, there will be all the traffic around you – aircraft that are ADS-B equipped, and those equipped with only with Mode C. You just need to be ADS-B in equipped to see this traffic package.

What will you need to be ADS-B compliant?

A panel mounted WAAS GPS, so ATC can read your position, vector, altitude and speed. GTN750 - $14,600. GTN 650 - $9,800. Both GTN models require ~25 hours to install.

If you have either a Garmin 430 or a 530 that are non-WAAS, the upgrade to WAAS will cost: $3,400 + 2 hours to install the WAAS antennae.

Some UATs (Universal Access Tranceivers) have a built in WAAS GPS – so if you install a UAT with GPS, you will not need a panel mounted WAAS GPS.

ADS-B “in”is broadcast on the 987MHz band. Benefits that you can receive:

•METARs & TAFs

•Non-Routine AviationWeather Reports (SPECI or Special Report)

•NEXRAD

•Both Distant and Flight Data Center (FDC) NOTAMs

•AIRMETs and SIGMETs, including Convective SIGMETs

•Special use Airspace (SUA) status

•Temp Flight Restrictions (TFR)

•Winds and temps aloft

•PIREPS

Extended Squitter Transponders – ADS-B Out only (transmits position, etc.)

•GTX 330ES transponder –$4,200 + 10 hours to install

•Honeywell/Bendix King KT74 - $3,200 + 2 hours to install. It’s a plug in replacement for the King 76a or 76c and the Garmin 327 transponders.

UATs – ADS-B “In”(display weather and traffic)and “Out”(transmit position, etc.)

Garmin GDL 88–has four models:

  • Basic(non-WAAS)- $4,000 + 24 hours to install
  • Diversity with top and bottom antenna (Non-WAAS) -$4,200 + 24 hours to install
  • Standard with WAAS - $5,500 + 24 hours to install
  • Diversity with WAAS - $6,000 + 24 hours to install

NavWorx ADS600-B (UAT) Includes a WAAS GPS - $4,600 + 24 hours to install

Aspen Avionics ATX200, requires Evolution 1500 - $4,000 + 24 hours to install

FreeFlight RANGR - $3,000 - $3,200 + 24 hours to install

FreeFlight RANGR TX with WAAS - $4,600 + 24 hours to install
