Those Avanti's are based out of Essex County (Caldwell Aiport) I think the main draw is that you can use a very small field and wont have to commute to the larger airports.
They are also based at about 10 other airports nationwide, the idea is to be able to get one to you in a few hours, since its a timeshare you dont own a particular one you just have a preset amount of time on any aircraft, that means you should see the interiors, what a mess. At least with the planes im with the owner has a vested interest in keeping it imaculate. Since these guys may never see the same plane twice they dont care......
I told my friend he is nuts, they wont last, they never do.
Most autotopians would drool over how well kept the corporate aviation fleet I work with is maintained.
About that radar, sometimes its the ILS (instrument landing syetem) but a lot of state DOT's use radar signals to monitor the flow of traffic to spot tie ups and accidents. Its not used for speed enforcement but it does give lightly patroled areas live feedback to some central location of the current roads average speed. I know they have several of them on RT 80, one near Rockaway and one near the RT 80/280 Split. If you look closely you can see them, look like flat panels under an overpass, almost like a small cell antenna.
