The
Hawk 5 (five place) Gyroplane brings to aviation a unique aircraft
with many utilitarian qualities. The Hawk’s performance
and exceptional versatility also offer a safe and affordable alternative
to helicopters and airplanes in many applications. The aircraft’s
simple, robust, design translates into lower operating costs than
any comparable turbine powered helicopter. The wide operating
speed range, from 46 - 162 mph, of this highly maneuverable gyroplane
also ensures the Hawk 5 a new niche in the aviation marketplace.
The Hawk 5 design, intended for series production following certification,
incorporates modifications gained from GBA’s experience
with its Hawk 4 (four place) prototype. These include a weight
reduction program and an extended cabin that will permit an additional
passenger. The Hawk 4 was an integral part of security during
the 2002 Winter Olympic and Paralympic Games. The Hawk 4, during
its operational period for the Utah Olympic Public Safety Command
(UOPSC), was available 24-7, completed 67 missions and accumulated
75 hours of maintenance free flight time. The production model
Hawk 5 Gyroplane offers many improvements to this already impressive
aircraft. Most notably are: higher capacity; vertical take-off
and landing; a marked increase in useful load, range and endurance;
and higher maximum and cruise speeds. Easy to fly and always in
autorotation, the Hawk 5 offers uncompromising safety in the realm
of flight.

GBA
announced in December, 2006 that a Memorandum of Understanding
has been signed with the government of Aragón, Spain to
form a joint venture (JV) to complete FAA certification, production,
marketing, and delivery of GBA’s Hawk 5 Gyroplane. The intent
of the parties is that the JV will acquire from GBA for an as
yet undisclosed sum, the Hawk 5 program including its derivative
gyroplane aircraft designs and technologies. It will fund GBA
to complete FAA certification of the Hawk 5 Gyroplane on behalf
of the JB in the United States, commence setting up new as well
as re-establishing existing Hawk Gyroplane dealerships throughout
the world, while taking advance orders, and build and operate
a factory in Aragón, Spain for world wide deliveries. Please
