ADS-B Out Diagram


ADS-B Out is the broadcasting part of ADS-B (Automatic Dependent Surveillance – Broadcast).  Through a transmitter, aircraft data such as airspeed, altitude, location and identification is broadcast to ADS-B ground stations.  In most cases, the real-time data that is received by air traffic controllers is more accurate than the data provided by current radar-based systems.

How does it work?

Determine Aircraft's Location

Using GPS and an ADS-B transponder, an aircraft’s exact location is determined.

Broadcast to Ground Station

The aircraft’s information, such as airspeed, altitude, and location, is broadcast to ADS-B ground stations as well as to other nearby aircraft.

Ground Station Relays to ATC

Ground stations relay the information to air traffic controllers.

Broadcast Back to Aircraft

A signal with flight data and radar weather is broadcast back to the aircraft from the ground station.

Broadcast to Nearby Aircraft

Aircraft equipped with ADS-B In will receive nearby aircraft’s information such as airspeed, altitude and location.

73% of aircraft are still in need of ADS-B Out

“Mandate upgrades are averaging 1,779 installs per month. Even at the high end, that would leave over 100,000 aircraft grounded on the first day of 2020. And even if fliers rushed to add the technology closer to the deadline, they’re likely to run into delays, since the number of aviation shops that can install it are limited.”

5 Myths about the ADS-B Out Mandate
Myth #1

The FAA will extend the mandate deadline

Not going to happen. Anyone who’s attended an FAA event or seminar on ADS-B Out can attest to the fact that the January 1, 2020 deadline will not be extended. It’s usually the first thing an FAA presenter will point out. Watch FAA Aerospace Engineer, Alex Rodriguez’s presentation on ADS-B Out.

Myth #2

I’ve got plenty of time

With an estimated 15,000 business aircraft to be grounded on January 1, 2020, you know a significant number will be due in part to shop unavailability. As the deadline nears, operators rushing to add ADS-B Out technology will be met with delays since shop availability will be limited or completely unavailable.

Myth #3

If I wait, prices will drop

If you read Myth #2, you probably already figured out that the the law of supply and demand busts this myth. Equipment manufacturers have stated that their prices are as low as they’re going to go and if anything, could go up due to the last minute rush on a depleted inventory of equipment.

Myth #4

ADS-B Out doesn’t benefit pilots or operators

Unlike some previous mandates, pilots and operators benefit significantly from the ADS-B Out mandate. Areas currently not covered by radar systems will now have surveillance provided in these remote locations. Airspace traffic separation will be reduced allowing controllers to plan further in advance thus decreasing an aircraft’s flight time — saving time and money! And if you include ADS-B In with your upgrade, you and your passengers will be able to receive the same traffic and weather controllers see.

Myth #5

I’m selling my aircraft so I don’t need to upgrade

Would you buy an aircraft today that doesn’t meet the FAA 2020 Mandate? Neither will any anyone else. An aircraft’s value in today’s market is significantly less if it’s not ADS-B Out equipped. Upgrade now to increase your aircraft’s value and potential buyers.

ADS-B Out Mandate – January 1, 2020

The FAA has mandated that aircraft must be equipped with ADS-B Out when operating in airspace that requires a Mode C transponder:

  1. Class A, B, and C airspace.
  2. Class E airspace within the 48 contiguous states and the District of Columbia at and above 10,000 feet MSL, excluding the airspace at and below 2,500 feet above the surface.
  3. Class E airspace at and above 3,000 feet MSL over the Gulf of Mexico from the coastline of the United States out to 12 nautical miles.
  4. Around those airports identified in 14 CFR part 91, Appendix D.
The ADS-B Out mandate is happening – it will not be delayed.

At a recent Banyan NextGen event, FAA Aerospace Engineer, Alex Rodriguez, discussed everything you need to know regarding ADS-B and NextGen Capabilities.  The video is available via on-demand by clicking the video image link on this page.
