Gulfstream announced today that the second G250 flight-test aircraft, S/N 2002, successfully completed natural icing tests, bringing the super-midsize jet closer to its planned FAA and Israeli CAA certification later this year. The twinjet was flown from its home base in Tel Aviv, Israel, to Smyrna, Tenn., where it spent several weeks flying to the Great Lakes region to hunt for natural icing conditions aloft.
Gulfstream has completed several icing certification test points on the G250. S/N 2001 has flown with simulated ice shapes applied to the non-heated areas of the aircraft, including the nose, tail, winglets and engine pylons. Meanwhile, S/N 2002 completed anti-ice system dry-air testing, paving the way for certification flight testing into known icing conditions, which at press time were expected to start in the U.S.
