Aeronautical’s new Spectrum 33 light twinjet made two more
test flights on Thursday, February 2, 2006. Both flights added a
little over an hour to the bird's log.
It almost didn't happen... the day began with steady rain, 500
ft ceilings, and a dropping barometer, but an unexpected late
afternoon break in the weather allowed Bill Davies,
Spectrum’s veteran Chief Test Pilot and Ian Hollingsworth,
second-in-command, to complete the hoped-for flights.
The new tests followed improvements and adjustments to some of
the aircraft’s systems that were made after its first flight
on January 7th. Davies said the 33 felt solid in longitudinal
control, and exhibited excellent yaw characteristics during
"We were able to conduct shallow coordinated turns with rudder
input alone," he said, "and saw excellent control in all axes." He
noted that the Spectrum 33’s takeoff acceleration and climb
performance "is well beyond anything I’ve seen in this class
"Takeoff distances for the flights were less than 800 feet,"
Davies commented, "and touch-down speeds were 85 knots with 15
degrees of flaps."
"Control during flap deployment required only minor changes in
trim, and the ability to hold nose-up attitude during landing was
excellent." He added that, "the tests are confirming that the 33 is
highly stable, docile and easy to fly for single-pilot
Linden Blue, Spectrum Aeronautical’s founder and CEO, said
he was pleased with the outcome of the flights. "These results are
further confirmation that the Spectrum 33 is capable of performing
a wide range of multi-role missions, and will benefit a broad
segment of the market."
The Spectrum 33 is a new light business jet that’s built
using carbon-graphite construction that gives it virtually the same
size cabin as popular eight to nine seat light business jets, at
less than two-thirds the weight. It’s designed to cruise at
FL450 at speeds up to 415 knots [477 mph] and fly as far as 2000
nautical miles while using about half the fuel of comparably sized
current production aircraft.
FAA Type Certification of the Spectrum 33 is slated for 2007 or
