Spotting Helicopters

As helicopters are of particular interest to me, I looked for a way of filtering them. Could not find any easy way, so simply set speed limits of 0-140 knots. This is not perfect as it will spot aircraft at final approach speeds, but will filter out most other fixed wing traffic.

If anyone else has a way of using filters, let us all know, please.
Hello John,

Sorry for my late reply. I know that PlanePlotter users filter helicopters using conditional expressions (condex).
There are a few messages about that on the PP mailing list.

PlanePlotter works nicely in conjunction with the Plane Finder receiver.
