ADS-B, EFIS and AHRS

Please be aware of the limitations of ADSB receivers. They do not detect Mode S unless there is also an ADSB signal, nor do they receive Mode A / C. For reception of FLARM a separate subscription is required of ca. €30,00 per annum depending on the app being used. Although ADSB Out is currently not compulsory in Europe there are ongoing discussions within EASA to change this and to permit the use of ADSB Out on units such as SkyEcho 2. Weather via ADSB is currently not available in Europe although there have been a number of very successful trials in recent years. Some apps (notably SkyDemon) require that an ADSB receiver has an on-board barometer - for example SkyEcho 2.
