+xIt probably means the other aircraft are misconfigured such that they are reporting that they're in the air. Makes sense, since it's not all of these aircraft. Mostly gliders, which are lined up waiting to be towed.

+x+xI'm still getting the occasional traffic alert from aircraft on the ground - is this a config option that I have not set right, or perhaps the other aircraft's ADS-B/FLARM is not working right? Thanks! Actually, to clarify, I don't get the alerts when I'm on the ground, but as soon as I rotate, it gives me warnings from all the aircraft on the ground behind me that are about to depart. I have the same problem. I guess it depends on the used protocol as well. In the case of FLARM you have to rely on the ground speed, GDL90 has a very specific field: 
Just to make sure: I still prefer to see the traffic which is on the ground, just the warnings need to be suppressed.

Sir Tim - thanks!
Would be good for a “cherry on the top” to have
1) the ability to switch this on and off (to keep naysayers happy)
2) I still find it distracting on final approach as well.
Here I think they best option would be to prompt the user via a dialog to confirm if they’re joining for approach. This could serve several purposes
A) bring up approach charts, VFR geo-ref plates etc, show joining / circuit pattern. SD does this all today but sometimes you don’t want these features at the time they appear
B) use the same dialog to then adjust the traffic audio. There’s been some really good suggestions on algorithmically how to do this. Eg if you normally warn on traffic +\- 2000ft then reduce this whilst within 3nm of AD

+xThe next release of SkyDemon does now ignore aircraft that we think are on the ground, while you are flying. There are two ways in which we judge an aircraft to be on the ground:
1. Its ADS-B packet tells us that it is on the ground (we check this with its reported speed, too) or 2. For protocols that are not ADS-B based, we need its speed to be below 10 knots AND its reported GPS altitude to be below terrain elevation plus 200 feet.
SkyDemon already omits to give traffic information updates when you are on the ground yourself. Thank you Tim, I look forward to testing it!
(Assuming I'm ever allowed to fly again by the Welsh government  )

+x+xWe should welcome a scenario where everything is visible, incl drones. No.
If there is a thread in the vicinity we have to find supporting solutions and it is most likely far beyond praying to the gods of technology, but - over-flooding the world and especially people not even involved in the particular situation with overwhelming and mostly useless information for them is the wrong way.
