Hi Mike (et al), yes, ADSB will give direction and altitude in a TCAS system. But if you are "just" a glider pilot and you purchase a powerflarm - it still is not the best solution. Just more expensive. If you have a PowerFlarm and hook transponder data into it: you do not get a direction warning indication, just "incoming". Only Flarm traffic is shown comprehensively, even with climb rate etc... The direction / altitude data from a transponder only appears after you throw a few thousand dollars more at your glider instrument panel and get additional boxes containing magic smoke.
TABS: "Traffic Advisory Broadcast System". >From my understanding: it is backwards compatible: It is another (new) box containing magic smoke and is able to mix Flarm and transponder smoke. It will cost less than buying a transponder and powerflarm. "TSO-C199" is the data-sheet for the new smoke. http://www.icao.int/APAC/Meetings/2015%20ADSBSITF14/SP08b_FAA%20TABS%20briefing.pdf I am looking after my original OZFlarm and wait for TABS. However, encrypting the Flarm protocol would mean I would have to fork out $2500 for a powerflarm just because the Flarm makers are greedy and want all other manufacturers out of their business. My existing OZFlarm would be useless even as a paperweight since it is too light (that's why it is great for a glider). The good 'ol flarm can be configured via software (by the user) to operate at different frequencies - to work in different countries. Later Flarm firmware versions switch frequencies automatically and allow you to take a flarm from Europe to the US and Australia without any problems. Powerflarms have to be configured by the manufacturer to change frequencies - and the Flarmin Swiss Company will charge a few toblerones for that! Why? because they can! ...make sure you select the "US/Australia" powerflarm from the millenair website, if you really have to buy a powerflarm and can't wait for TABS. Third party manufacturers such as LX Nav / LX Navigation utilise the good 'ol flarm in their devices - that's why they switch automatically according where you are. However, I can foresee that being stopped by the "flarm data encryption". You will need two powerflarms: One for Europe and the other for US/Australia. A bit like no longer being able to take your phone overseas and just using it with a sim card from that country.. Lucky for us users: there are enough brainy people out there that are capable of designing something that is far superior to flarm.
