+x+x+x+x+xTony, Markus, Mike,
Many thanks to all of you.
I am not sure that the workshop has connected my Garmin GPS to the Trig TT21 transponder. I suppose yes. I will fly tomorrow and will take the opportunity to try to configure the transponder (GPS type, speed transfer..). I will be able to check it by displaying the ADS-B Monitor (see Tony's message).
About FR24, I understood that the signals were intercepted on the ground by a network of "private volunteers" with as main material the reading of ADS-B signals. Some of then are also equipped to receive the C / S transponder but are less numerous. I thought it was because of this reason that I do not always see my aircraft in FR24 but sometimes only short portions of my flights ... and always at the same places. But I am not an expert on FR24 and I can, of course, be wrong
Many thanks for your help.
You can easily check whether FR24 receives your position by ADS-B or has calculated it by multilateration. Click on an aircraft symbol and the aircraft details will be displayed, at the bottom of this stack you will find: where the position is received from the transponder itself, or: where the position is not retrieved from the transponder, but by multilateration (MLAT) calculation.
The first ADS-B transponders were not able to transmit the position by 'extended squitter' (ES), many aircraft owners has changed their old transponder by a Garmin transponder without ES. In the same period, newcomers like TRIG, Garrecht or FUNKE where putting the first ADS-B wit ES on the European GA market. But almost no aircraft owner realizes the purpose of ES and neglected to connect the ES capable transponder to their (approved) GPS. Since years you can upgrade your 'old' Garmin transponder into a ES capable transponder. Many aircraft are ready to transmit their position, but it takes 2 wires between the GPS and ES capable transponder (and a sign...)
I remember when I switched XPDR, these two wires were 10 cents in parts, 5,000 Euro to upgrade to WAAS GPS and 2,000 Euro for sole paperworks, so I stayed unconnected and non-WAAS. Btw, what happened to the initiative allowing certified non-WAAS GPS sources, silent death? Attaching a non-certified position source to an ES transponder has been permitted for some time in the UK for non-EASA aircraft.
IN my (EASA) AA5 I've just had my GNS430W (legally  ) attached to my Trig TT31 for ADSB-out via the no-cost Trig STC and signed off under CS-STAN. The whole cost was peanuts (given I already had a GNS430W). Upgrading to WAAS for the sole reason of ADS-B out just seemed over the top to me. I know of the UK special way of uncertified sources, but also know of the several complaints of airliner pilots, disabling the annunciation of these targets = no real use for that. I wonder what will happen to this UK speciality after Brexit. It won't just be a 'UK special' way after a month or so, as EASA have just announced that the revised CS-STAN for ADS-B via a Mode S will be issued imminently. It allows three flavours - with certified position source, with a TABS device, and with a non-certified source. It defines the SIL and SDA values to be used in each case. That's also the your answer to your final question, whatever happens as a consequence of Brexit, as far as EASA types are concerned. For UK regulated non-EASA types, I assume the status quo will continue.

Just because an aircraft shows up on FR24 does not necessarily mean that it is equipped with ADS-B Out. FR24 can display aircraft with Mode S and no ADS-B Out, and aircraft with Mode A/C only, using a technology known as multilateration (MLAT) and ground based receivers.

+x+xMany thanks everybody for your messages. I think this subject is verry interesting even it wil never replace the eyes. But every help is welkom.
I'm currently trying to configue my Trig TT21 to broadcast ADS-B out. Then I will probably investigate to buy the most appropriate ADS-B in compatible with SkyDemon.
If I understood correctly, one tips to verify that my transponder broadcasts ADS-B out is to go on flightradar24. If I see my plane, it's because it's broadcasting in ADS-B out. Frederic, I have a TT21 and have connected an uncertified GPS mouse to it to produce the ADS-B out capability. Yes, FR 24 is good for checking as is Planefinder. Your Trig TT21 also has a feature where it displays your current Lat, Lon and Ht on the display so you can verify your interface is working okay. Tony Is enabling ADS-B out with an uncertified GPS legal? Even if, you are contributing to 1090 congestion without being visible to the airliners. Just a short comment.
