Honeywell's Legendary Boeing 757 Test Aircraft Turns 40 Years Old

Turning 40 years old signals the beginning of middle age for most people, but when an aircraft turns 40 years old, that is a bigger milestone altogether. Most passenger aircraft are retired and scrapped by age 40, but for Honeywell's iconic Boeing 757 test aircraft, turning 40 simply means there is much more high-flying adventure to come.

Honeywell's Boeing 757-200 testbed has been utilized for research and development by the aerospace leader since it acquired the aircraft in 2005, but its history stretches back to when it rolled off the production line in June 1982. Thereafter, the aircraft entered service for Eastern Airlines in 1983. It was just the fifth 757 to roll off the assembly line, and more than 1,000 would eventually be produced. Although 757s are still in service at airlines around the world, many have been retired in recent years and replaced with newer aircraft.

Honeywell Aerospace's test flight department and engineers have utilized the 757 to test many of the technological advancements that the flying public enjoys today. From turbine engines to electrical and mechanical systems, to advanced avionics software and high-speed connectivity equipment, the 757 has touched a bit of everything in aerospace.

"For the past 17 years, we have made so many technological modifications to our beloved 757 test aircraft that the only thing turning 40 years old is likely the fuselage itself," said Captain Joe Duval, director, Flight Test Operations, Honeywell Aerospace. "We're among a select few pilots in the industry who have the responsibility to push an aircraft close to its limits. We've intentionally flown into nasty storms to test our radars, and we've flown toward more mountains than I can count to test our ground proximity warning systems. Our 757 has been the dependable workhorse that allows us to test a whole slew of technologies, including the engines we produce for business jets and smaller aircraft."

The pylon protruding from the fuselage of the 757 is likely its most noticeable characteristic. Although a third engine isn't always attached, the pylon allows Honeywell to test its turbojet and turbofan engines in real-world conditions and gather critical data that helps with engine development.

"The plane tends to draw a lot of attention, whether we're at an airshow with thousands of people or I'm scrolling through Twitter, and I notice a plane spotter that posted a photo of it," Duval said. "It has a special place in the AvGeek community, and I'm glad it does because it's helping create a more sustainable and digital future for aviation."

Although most 757s spend their life as a medium-haul aircraft shuttling about 200 people between a pair of destinations, Honeywell's testbed has only 25 seats to accompany a wide variety of flight test engineering stations. Despite the limited capacity, Honeywell's 757 is amazingly well-traveled. The test aircraft is likely the only existing 757 that has traveled to more than 30 countries across five continents. It has conducted more than 800 flight tests and clocked more than 3,000 flight test hours globally.

Technology that has been tested on Honeywell's 757 testbed includes:

• IntuVue RDR- 4000 Weather Radar and IntuVue RDR-7000 Weather Radar – Honeywell's family of advanced 3D weather radar systems for air transport, business and military aircraft. IntuVue Weather Radar provides reduced pilot workload and increased situational awareness of weather, resulting in improved routing around hazards and increased safety that is superior to 2D radars.

• Next-generation flight management systems (NGFMS) – An FMS provides the primary navigation, flight planning, and optimized route determination and en route guidance for an aircraft. With a completely redesigned architecture, the NGFMS software was built to utilize a modular design that allows for aircraft-specific adjustments in hardware, operating systems, input/output (IO) and other features.

• HTF7000 engine series – The HTF7000 engine series are business jet propulsion systems well-known in the industry for their reliability, durability, and maintainability.

• Honeywell's JetWave and JetWave MCX – Honeywell's JetWave provides in-flight Wi-Fi that is fast, reliable, and available anytime, anywhere and at any altitude. The JetWave MCX system delivers the world's most advanced high-speed satcom capabilities for demanding military missions and is built on the proven, high-speed JetWave technology.

• Aspire 350 and 400 – The Aspire suite of satellite communication offerings provides in-flight connectivity for business aviation, airlines and helicopters—anywhere in the world.
