The ARC airport deal
was that quiet 2lb 60mph models dont interfere with fullscale near airports,
but loud 2lb 60mph models do
... you know, cause they are loud
sUAS ARC 3.3
(4) Model Aircraft shall not be operated within 3 NM miles of an airport, heliport, or
seaplane base without the permission of the ATC authority or airport manager.
(6) Notwithstanding the above limitations, Model Aircraft weighing less than or equal
to two lbs incapable of reaching speeds greater than 60 miles per hour (mph)
(52 knots), and powered by electric motor or mechanical stored energy (e.g.,
rubber-band powered) may operate within 3 NM of a military or public-use airport
or heliport; if they remain a safe distance from the airport or heliport, remain well
clear of all manned aircraft, and remain below 400 AGL.
Now, under AC91-57 2lb model flyers NOTIFY airports of what we are doing,
under the ARC we would have to BEG PERMISSION from airports to do it
... well, unless you are quiet, then you dont even have to notify anymore[&:]
