Gulfstream G250 completes several tests


Gulfstream G250 test aircraft complete several certification milestones

The Gulfstream G250 executive jet is on
schedule for certification later this year, having recently completed several
tests required for it to receive its type certificate from the Federal Aviation
Administration, the Civil Aviation Authority of Israel and the European
Aviation Safety Agency.

The three flight-test aircraft have
accumulated more than 1,150 flight hours over more than 400 flights.

“We are on track and steadily moving toward
certification this year,” said Mark Kohler, director, G250 program. “The
aircraft is performing exceptionally well and will soon take its rightful place
as the world’s best-in-class super mid-size business jet.”

The second of three aircraft in the
flight-test program, successfully completed water ingestion testing in late
March in the United Kingdom.
As required by Federal Aviation Regulations, the tests confirmed that the
aircraft’s two Honeywell HTF7250G engines, its auxiliary power unit and its
airspeed system will continue to operate normally even after traveling through
standing water.

The third flight-test aircraft completed the
first phase of human factors testing at the company’s headquarters in Savannah in April. The
testing included avionics performance and flight-deck ergonomics. Each
six-member crew flew three flights: a day Visual Meteorological Conditions
(VMC) flight, a day Instrument Meteorological Conditions (IMC) flight and a
night VMC flight.

During human factors testing, each of the
two-hour flights begins as a normal flight. Human factors engineers then
introduce scenarios that force the crew to perform other tasks, including
potential abnormal and emergency procedures. At the end of each flight, the
crew completes a questionnaire, and the responses are used to create a report
for certification.

The second phase of human factors workload
testing will include representatives from each of the certification
authorities. Results from both phases will be submitted to the certification
authorities for certification credit.

To receive its type certificate, the G250
must finish the remaining aircraft systems and field performance tests as well
as a portion of the more than 40,000 airframe fatigue cycles, which are already
under way at Israel Aerospace Industries. The aircraft have completed static
structural, limit/ultimate load, natural icing, far-field noise and high-field
elevation tests.
