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.

N757HW takes off from Runway 8 at 9:49 AM.
The test engine is an AS907-1-1A for the Challenger 300. It carries a decal for the J4TF7500E which is the AS907-1-1E for Embraer.
N757HW flew southeast to the "Gunslinger" restricted operating area over Southern Arizona and New Mexico.
N757HW landed on Runway 25 Right at 1:17 PM.

N757HW is testing a Honeywell TFE731-60 geared turbofan with approximately 5,000 pounds of static thrust. It has a bypass ratio of 3.9. The TFE731 was introduced by Garrett-AiResearch in 1972. It was derived from the core of the TSCP700 which was the auxiliary power unit of the McDonnell-Douglas DC-10. A wide variety of business jets are powered by variants of the TFE731. The TFE731-60 is used on Dassault Falcon 900DXs. It is 72 inches long and weighs 988 pounds
N757HW lines up with Runway 26 at 8:27 AM.

March 26, 2010
Honeywell's 757 engine testbed on approach to land on Runway 26 at Phoenix Sky Harbor International Airport on March 26, 2010. It was returning from a flight over southern Arizona and New Mexico. It flew over Gila Bend and made some circuits of a racetrack pattern in the "Gunslinger" restricted operating area. It is trailing an airspeed calibration cone from the tip of the vertical stabilizer.
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.
Close-up of the test engine installation.
The HTF7000 has a thrust rating of 6,500 to 7,500 pounds. It has a bypass ratio of 4.4. Its fan diameter is 34.2 inches, and it weighs 1,364 pounds.

Honeywell's 757 engine testbed is based on the north side of the airport. A portable work shelter is visible to the left of the airplane.
N757HW departed from Runway 8 at 9:30 AM MST on February 1, 2010. It was conducting a production acceptance test of an AS907-1-1A turbofan engine for the Bombardier Challenger 300 business jet.
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.
The Honeywell 757 engine testbed returned to Runway 8 at Sky Harbor 2 hours and 44 minutes after taking off.
N757HW deployed its thrust reversers to decelerate
