phpcrzoumpmFeb. 2, 2009, Montreal – Bombardier Aerospace announced today that it is now offering a
Wide Area Augmentation System (WAAS) capable Flight Management System (FMS) on
Learjet 40 XR and Learjet 45 XR aircraft.

The new system is available as a Supplemental Type
Certificate (STC) for in-service Learjet 40, Learjet 40 XR, Learjet 45 and Learjet 45 XR aircraft
customers and will also be offered as an option on new aircraft.

Provided by Universal Avionics Systems Corporation (UASC), WAAS enhances navigation
capabilities through the use of a network of ground reference stations collecting global
positioning system (GPS) satellite data. This data is broadcast to user aircraft through two or
more geostationary satellite communication links. The aircraft uses the WAAS signal, in addition
to the GPS service to fly area navigation and localize performance with vertical guidance (LPV)
instrument approaches. LPV approaches offer pilots lower landing minimums, resulting in more
flexibility for landing decisions.

The WAAS system is managed by various representatives from the Federal Aviation
Administration (FAA) and the aerospace industry. The FAA recently announced that a total of
1,390 new WAAS approach locations are available and capable of allowing Learjet operators to
utilize this system. Currently it is only available for North America.


WAAS can be installed at all Bombardier Aerospace Service Center locations. Operators should
contact their Bombardier regional manager for additional details.

Learjet 40 XR: The six-to-seven passenger Learjet 40 XR aircraft features the widest and most spacious cabin in its class and a full aft lavatory. This premium light jet delivers impressive
time-to-climb performance under all conditions – particularly in hot and high operating
environments – requiring only 23 minutes to reach 43,000 feet (13,106 m).

Learjet 45 XR: The eight-to-nine passenger Learjet 45 XR aircraft flies faster than any other
aircraft in its category, while offering the best fuel efficiency and lowest direct operating costs
With a true double-club configuration, the spacious cabin offers seated passengers exceptional
head and shoulder room. The aircraft can fly 1,824 nm (3,378 km) with eight passengers with
NBAA IFR (100 nm) fuel reserves.
