jack ranga use of the great "They" is spurious.
the real problem that people like me (yes I'm a people) have with ADSB is the lack of suitable units.
when I fly into kalgoorlie or newman or port hedland, as I have done, I occupy 3 dimensional space with my metal bits so you cant just fly a Boeing 717 through me and pretend there wont be a problem.
to say that adsb units arent mandated for the light aircraft misses the point.
we have essentially the same problem as Dick.
what adsb unit can be used????? why isnt there a standalone unit that can be fitted simply into an avionics rack???
fer fckus sake all aircraft need an adsb unit for the system to work properly in terminal areas.
if the system (casa, air services etc ) can beat on our heads for fitment why can't they persuade the makers to put out units that can be used?
