Where are the Aer Arann flights?

That probably is the reason, although I spotted a few ATR’s operating around the Med.

From the Flightradar24 site, is this actually correct about only 60% carrying ADS-B equipment?

Flightradar24.com shows live airplane traffic from different parts around the world. The technique to receive flight information from aircraft is called ADS-B. That means the Flightradar24.com can only show information about aircraft equipped with ADS-B transponders. Today about 60% of the passenger aircraft and only a small amount of military and private aircraft have an ADS-B transponder.

Most prop aircraft including ATR’s and Dash Eight’s don’t transmit the required information for them to be tracked by Radar Virtuel and Flightradar24.

Probably the same reason that virtually all of FlyBEs flights are missing as well. There is a listing of aircraft types that they don’t cover which includes Dash 8s.

pretty sure they operate as aer lingus regional

though that dosent explain their mainline routes going missing

You’re right! Mystery to me as well.:confused:
