The Garmin ADS-B Experience

Reports from Actual Pilots

ADS-B is on its way, and it promises to change the way you fly. While it’ll make our skies safer, it’s not always the easiest system to understand. Lucky for you, the ADS-B Academy is here to give you the resources you need to make smart, informed decisions about how to transition to this new air traffic technology.

Common Questions about ADS-B

When should I equip for ADS-B?

When you’re required to equip for ADS-B depends largely on where you fly. In the U.S., you must equip by 2020. But in other parts of the world, you may be required to equip much sooner. Regardless of regulations, you can equip today to start taking advantage of ADS-B’s benefits.

What is ADS-B “In” and ADS-B “Out”?

With ADS-B (Automatic Dependent Surveillance – Broadcast), you’ll be required to broadcast your position information to ADS-B ground stations and other aircraft. This is called ADS-B “Out.” But those ground stations are also broadcasting valuable information you can use if your aircraft is equipped to receive it using ADS-B “In” technology.

What is an approved ADS-B position source?

With ADS-B, each aircraft needs an approved ADS-B position source to calculate its precise position using highly accurate WAAS/SBAS GPS data. This position is then broadcast to ATC and other ADS-B “In” equipped aircraft in their vicinity.

How do I equip for ADS-B?

There are a lot of things to take into account when planning your ADS-B installation — like your current aircraft configuration and what ADS-B benefits you’d like to take advantage of. View the video for help understanding all the factors involved. Then use the planning tool below to get a detailed hardware recommendation based on your specific needs.

How do I broadcast my ADS-B information?

You can either broadcast your information using an extended squitter or by using a universal access transceiver. Which option is best for your aircraft depends on where you fly and what equipment you might already have installed.

Who needs ADS-B?

Simply put, anyone who flies in controlled airspace will need an ADS-B “Out” solution. But even if you don’t currently fly in controlled airspace, there may still be situations where you’ll be required to be ADS-B “Out” compliant in the future.

Why are we switching to ADS-B?

ADS-B allows air traffic controllers to route traffic more efficiently, reducing congestion, noise, emission and fuel consumption. It also promises to keep our skies safer by enhancing situational awareness. And even better, properly equipped aircraft will gain an affordable way to get datalink traffic, as well as subscription-free weather over the U.S.
