Bell 429 performance update

Feb. 25, 2009, Fort Worth, TX – Bell Helicopter this week gave a 429 program update
that provided the most recent performance data accumulated during the
on-going flight test program. 

"As we work our way through all the required test points established
in our flight test program, we continue to be pleased with what the
data is telling us. Without exception we are exceeding every
preliminary performance goal we set going into the program," said Neil
Marshall, director of program management for the 429.

The 429's maximum airspeed in level flight with maximum continuous
power (Vh) has improved from 142 to 150 knots with skid gear. Maximum
range at Vh has increased from 312nm (578km) to 332nm (615km), Virc
(long range cruise) range has increased from 350nm (648km) to 368nm
(682km) and maximum endurance from 3.8 to 4 hours. The 429's HIGE has
grown from 11,000 ft (3353 m) to 14,130 ft (4307 m) and HOGE from 9,300
ft (2835m) to 11,280 ft (3444 m).

"The aircraft is proving to have excellent ride quality and the
lowest take-off and approach noise level of its class," added Marshall.
"It has outstanding Cat "A" performance and exceptional center of
gravity envelope."
Standard specifications show the cabin volume has grown from 200 cu
ft (5.7 kg) to 204 cu ft (5.8 Kg) while empty weight has increased by
60 lbs, reducing the useful load from 2700 lb to 2640 lb.
