(d) Converging. When aircraft of the same category are converging at
approximately the same altitude (except head-on, or nearly so), the
aircraft to the other's right has the right-of-way. If the aircraft are
of different categories--
(1) A balloon has the right-of-way over any other category of aircraft;
[(2) A glider has the right-of-way over an airship, powered parachute,
weight-shift-control aircraft, airplane, or rotorcraft.
(3) An airship has the right-of-way over a powered parachute,
weight-shift-control aircraft, airplane, or rotorcraft.]
However, an aircraft towing or refueling other aircraft has the
right-of-way over all other engine-driven aircraft.
