It's not clear what we could do about this, since if that vertical speed were true, you'd probably want to be warned.

The circuit was very busy due to airfield operational issues so I had to fly three circuits before landing. I didn't do "touch and go" - I just continued to fly at circuit height. Each time I overflew the airfield I received a warning about an aircraft at 35000ft above, overtaking at 330 Kt. I think this warning occurred three times. I didn't see anything on the moving map but wasn't really looking for long either due a fairly busy circuit. I think SD was detecting high level CAT in the airway above me, so likely a glitch in the SD traffic filtering algorithm. I have never detected anything similar at any other time and just use the standard default for a height filter in the basic SD setup. Tony
