We did a flight from Farnborough way to west side of Stansted and back today. I was using the newly upgraded PAW with Pi2 and latest software and the aircraft had it's own TCAS (Bendix King I think). PAW did give a good warning of a same level head on traffic before TCAS gave a TA. However there was lots of traffic TCAS advised of which PAW was unaware of. I assume this must have been Mode C and despite it being a good day for viz, it was hard to spot the lower level traffic. As usual, lots of ADSB CAT traffic was visible.
I guess PAW was useful but nowhere near as useful as it would be if it gave mode C alerts. Any timesacles when this faeture will be available?
