DISPLAYING TRAFFIC Alongside your ADSB receiver you need some form of display to show the traffic around you, and optionally generate verbal or visual warnings of potential conflict. The important factor here is to ensure that your chosen solution allows you to easily scan the display while still keeping a good lookout; electronic conspicuity is only an assistance to a good visual scan. It helps greatly to have audible warnings, either through voice or alarm sounds, and many solutions provide this.

Here there are three options, you can either have an integrated receiver/display, a dedicated traffic display, or use a moving map (EFB or integrated) that supports traffic data from your receiver.

 Moving map or electronic flight book (EFB) displays have the advantage of showing you where the traffic is along your route, but you should also consider the in-cockpit position of your mapping system in relation to your eyeline and whether you can get audible warnings.

- Most popular EFB software (e.g.SkyDemon, EasyVFR , ForeFlight, or AirNavigation) will interface to a variety of receivers, including Flarm, SkyEcho or PilotAware, as well as a number of the GPS/ADS-B receivers. Connecting between the receiver and

the electronic flight book is normally wireless, either Bluetooth or Wi-Fi. The vendors and receiver manufacturers will document the options available.

- If you have an existing panel mounted map display such as those available from Garmin or Dynon then they will often have capability of interfacing to a receiver and displaying traffic information. There is a wide range of options here, so it’s best to check with your vendor.

- Other software based ‘traffic radar’ displays can be used, for example PilotAware provide a simple traffic radar that can be used on a smart-phone.

 Receivers with an integrated or attached traffic display are noted in the table. Several Power-Flarm devices have this capability and displays range from a simple ‘LED-clock’ to a more detailed traffic monitor.

 A dedicated ‘traffic monitor’ often has a radar-like display showing multiple targets and normally integrated audible alerts for conflicting traffic. They can be mounted in the panel, or on the panel face or glare-shield and can be a simple ‘clock’ display or a more detailed ‘traffic radar’. Most are designed to operate alongside a PowerFlarm-based receiver, but some support other Display/Receiver interfaces.

Installation requirements depend on the maintenance regime you are using for your aircraft. Portable devices can be used in any GA aircraft provided they do not interfere with the controls, vision or electronics.

If you wish to connect a GPS source to your transponder or permanently install other electronic conspicuity equipment in a non-EASA aircraft the LAA and BMAA provide documented procedures. For EASA gliders most manufactures have a ‘blanket’ technical note allowing such installations

For EASA light aircraft many traffic devices are covered by Minor Change approvals or EASA Standard Changes (CS-STAN). In particular CS-STAN now also authorises aircraft maintenance engineers to connect a GPS position source (certified or non-certified) to an ADS-B capable transponder, but this work has to be done by a licensed engineer.
