AeroTech Services' B737 Airfoil Technology Reduces Fuel Spending and CO2 Emissions for Boeing Classics

28th October 2008 - 11:12 GMT | by The Shephard News Team


AeroTech Services, Inc., announced today that its modification kit for Boeing 737-200, -300, -400 and -500 aircraft is similar to, but more efficient than, the new Boeing Performance Improvement Package (PIP) for the B777s.

The Boeing PIP uses drooped ailerons to improve performance by 1%. "The AeroTech modification improves fuel burn performance and reduces CO2 emissions by 2% to 4% for a faster ROI [return on investment than other performance improvements," said James Nettle, a Director at AeroTech, "We droop the ailerons and the aft flap segments."

According to a recent press release from Boeing, ten Airlines have signed up for the B777 PIP, many of which also have significant fleets of B737s, including British Airways, KLM-Royal Dutch Airlines, Continental Airlines and Air New Zealand. Utilization of the AeroTech modification includes aircraft in the fleets of Swiftair, Quikjet, Donghai Airlines, and Ukraine International Airline.

"The major operators' awareness of the Boeing 777 PIP is just great for AeroTech. It completely confirms that AeroTech's airfoil improvement technology is an efficient way to improve performance on the B737s" said Jeff Donnelley, a Director with AeroTech Services. "Also, AeroTech already has the FAA Supplemental Type Certificate (STC) and their verified flight test results." He continued, pointing to the fact that FAA approval for the Boeing Performance Improvement Package is not expected until April 2009. The AeroTech B737 modification has approval from all the major aviation agencies: The United States Federal Aviation Agency (FAA), the European Aviation Safety Agency (EASA), Transport Canada, and the General Administration of Civil Aviation of China (CAAC).

AeroTech Services' modification increases the aircraft's wing area and camber, and lengthens the wing chord. This results in an increased lift-to-drag ratio, effectively reducing fuel burn and emissions during climb and cruise periods. The easy modification typically takes 300 man-hours to install and can earn back a 100% return on investment (in fuel savings) in a relatively short period of time of commercial use.
The B737 Classics is the largest fleet of commercially flown aircraft in the world, with approximately 2600 in service. "Even at an average 3% improvement in fuel burn efficiency on the B737s, it equates to reducing over 645 tonnes of CO2 emissions per aircraft, per year," Donnelley said.

AeroTech Services, Inc. was founded in 1995. James Nettle and James Lord filed a patent application in 2001 titled "Method for Reducing Fuel Consumption in Aircraft." The United States Patent & Trademark Office issued U.S. Patent No. 6,598,834 to them on July 29, 2003.

AeroTech Services, Inc., a Reno, Nevada-based company, holds the US Patent No. 6,598,834 on the wing modification for all aircraft. The company markets and sells the modification worldwide to commercial airline operators. For more information call (800) 294-2074, (702) 405-0325 or, visit the website at
