Stall Testing And Other Program Activities Proceeding
Gulfstream said Monday at EBACE that the wing, empennage and
engines have been installed on the third Gulfstream G250 test
aircraft, and testing of the aircraft's systems is under way. Known
as serial number (S/N) 2003, the aircraft will be used to test
systems functionality and reliability.

The G250 flight-test and certification program consists of three
aircraft and an estimated 1,300 hours of flight time. The first
G250 test aircraft, S/N 2001, joined the flight-test program on
Dec. 11, 2009, and is being used to examine in-flight performance
and handling. S/N 2002, which focuses on avionics testing, first
flew on March 24. Together, the two aircraft have accumulated
nearly 80 hours in flight, with S/N 2001 already achieving the
maximum certified speed and altitude of Mach 0.85 and 45,000 feet

"The G250 handles like a large-cabin Gulfstream aircraft," said
John O'Meara, chief test pilot. "It's a good-handling airplane. We
completed the aerodynamic stall test program, and the resultant
performance was even better than we predicted. It's very similar to
a Gulfstream V in terms of its handling characteristics."
Other aspects of the G250's test program are also progressing as
planned. Several structural tests have been completed, including
flap ultimate load, ultimate horizontal stabilizer down bending,
ultimate fuselage up bending and wing down bending. Additionally,
the fuselage has been joined for the fatigue test article.

Additional tests have been completed in the aircraft's
Integration Test Facility (ITF). The G250 is the first mid-size
Gulfstream with its own ITF. Based in Savannah, the facility has
been used to integrate the software and hardware for the jet's
state-of-the-art PlaneView 250 avionics platform and to develop the
procedures for the Airplane Flight Manual (AFM). Gulfstream also
used the ITF for the aircraft's human factors evaluation by the
Civil Aviation Authority of Israel (CAAI), the FAA and the EASA.
That evaluation is now complete.
The first G250 rolled out of the IAI manufacturing facility in
Tel Aviv under its own power on Oct. 6, 2009. It remains on
schedule for type certification by 2011, followed by
entry-into-service the same year.
