I agree that it is not a perfect solution and shouldn't be relied upon for separation but regarding your comment about an aircraft not being where the pilot expects it to be, isn't this the same problem with TCAS and all the other cheaper GA installations that try and display Mode C/S transponder returns on a map?
The difference in displaying traffic to the same app users versus cross EFB’s is again, if it’s run by the one provider, they can set their own thresholds for display. Eg if the aircraft doesn’t ping for 5 seconds, delete it from the screen immediately. If you’re getting a feed from elsewhere, how do you know what algorithm is in place to provide you with that traffic in the first place? How old is said traffic?
Anything hardware based with a direct live signal reception is y far superior in every way.
TCAS feeds coming from a hardware mounted receiver as going to be as close to real-time as you’ll ever get.
