Honeywell operates Boeing 757-225 N757HW as an engine testbed at Phoenix Sky Harbor Airport. It is powered by a pair of Rolls royce RB211-535E4B37 turbofans. It carries a third jet engine on the right side of the forward fuselage. The construction number of N757HW is 22194. It first flew on February 4, 1983. It was delivered to Eastern Airlines as N504EA on February 28, 1983. It was withdrawn from use at McCarren Airport, Nevada in January 1991. Airtours International Airways registered it as G-JALC on February 1, 1995. Airtours International Airways changed its name to MyTravel Airways on May 1, 2002. Honeywell International Incorporated gave it its current registration on October 4, 2005. It was flown to Pinal Airpark for painting on October 24, 2005. It made its first flight with three engines on December 20, 2008.

Honeywell 757 Engine Testbed N757HW, February 1, 2010 N757HW flew southeast and made four and a half circuits of a racetrack pattern in the "Gunslinger" restricted operating area over Southern Arizona and New Mexico at an about 32,000 altitude. Its ground speed varied from under 300 knots to over 500 knots.

Honeywell 757 Engine Testbed N757HW, March 26, 2010 N757HW is conducting production acceptance tests of an HTF7000 turbofan engine for the Bombardier Challenger 300 and Gulfstream G250 business jets. It is testing an improved combustor system that will provide better lite-off and longer life. The HTF7000 was previously designated AS907. That designation is still used for legal and regulatory use.

Honeywell Boeing 757-225 N757HW engine testbed, August 9, 2013 N757HW departed from Phoenix Sky Harbor for Fort Lauderdale, Florida at 9:16 in the morning on August 9, 2013. It had no engine mounted on the test pylon. Honeywell is beginning a test program with the Honeywell RDR-4000 and RDR-4B weather radars. The purpose or the testing was related to the predictive windshear features of the radar system. The testing involved flying into localized windshear conditions at low level to evaluate the effectiveness of the radar in predicting windshear intensity. Obviously such a capability on an airliner when landing during bad weather greatly enhances flight safety.
