Probably because they are not modeS or ADS-B equipped.

Hi 123, as Runway 31 says, not many General Aviation (GA) A/C have mode S or ADS-B.
ANRB :  AOR AR8000 : Icom R-7000 : Icom IC-R9000 : JRC NRD-545 : OptoElectronics Digital Scout and OptoLinx Interface; Realistic Pro-2005 : UBC 800XLT - listed in alphabetical order, not cost, preference, performance or entertainment value!

See this video on the AirNav YouTube channel, that will explain.

In a recent post on another forum, the point was made that a lightweight, ADS-B-compatible Mode A/C/S transponder suitable for GA, microlights, ultralights, gliders and balloons has been available for the last few years but can't be legally used because the CAA in the UK are dragging their feet over certification.

I'd post a link to the spec, but doubtless AirNav would then delete it  :-)

So anyway, until the regulators get their act together you're unlikely to see any dramatic increase in GA on the screen.

I can't see why a link to the spec would be deleted, unless it is a spec published by Kinetic.  Surely there is a CAA specification for this and more than one company intending to produce one?

I'd heard that one of the main sticking points is that a 'portable' transponder would not be associated with an airframe in the same way that a permanently fitted unit would be.

That's interesting!

I saw the TRIG unit at the Flying Show at the NEC - a very neat bit of kit, but you've still got that box of tricks to accommodate and not just the small remote display unit.  I think that the 'vision' was to have a transponder that was no bigger than a hand-held GPS.

Here is a link to the relevant page on the CAA website:
