Air Alliance Express (AAE) of Germany has purchased a third Raisbeck ZR Lite Performance System for its GRO fleet of Learjet 35As. AAE has been flying Lear 35As for more than eight years, and installed its first ZR LITE two years ago. One Learjet is also equipped with Raisbeck's Aft Fuselage Locker.

Air Alliance has recorded overall fuel savings of 5-7%, along with better take-off and climb performance, especially from hot and high airfields, and increased range. The company says the ZR Lite system is paying for itself in fuel savings alone.

"The improved take-off performance with the system enables us to depart our home base EDGS with a full fuel load," reports Matthias Kupisch, AAE head of ops. "However, a big part of our decision to install it on 35A-504 is the fact the system increased the value of the aircraft – it is even possible to sell an ageing Lear 35 if it has been equipped with the Raisbeck systems."

Raisbeck's ZR Lite Performance System enhances the takeoff, climb, cruise and descent performance of Learjet 31, 35 and 36 aircraft. In addition to being able to fly higher, faster and farther from more airports, ZR LITE saves at least 5% on fuel at normal cruise and up to 14% or more when pilots can take full advantage of the Learjet's improved climb and cruise capabilities.
