Gulfstream G250 Completes Several Certification Milestones By Jim Douglas |

May 18, 2011 - Gulfstream Aerospace Corp.’s large-cabin,
mid-range Gulfstream G250 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.” |

Aircraft Number 2002, 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 tests were conducted along a 5,902-foot runway during all
critical phases of takeoff, landing and taxi. The G250 performed
nine successful runs.
The third flight-test aircraft, Serial Number 2003, completed
the first phase of human factors testing at the company’s
headquarters in Savannah last month. 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. |
