20 Series FSX Add-on Package

The Xtreme Prototypes 20 Series for Flight Simulator X is inspired from a series of aircraft known in the 1970's as the Gates Learjet 24, 25 and 28. It contains six variations of the legendary business jets:

Retaining the time-defying design of the original Model 23, Model 24 brought airline-style systems redundancy and increased performance and safety. Epitomizing the private jet and often dubbed "Pocket Rocket" or "Fighter in civilian clothing", Model 24 flew above the weather and higher than most airliners, making its pilots and passengers members of a rather exclusive club.

With Model 25 came a longer cabin, increased seating capacity and more flexible loading options, not to mention a rather sleek-looking stretched fuselage. The Model 25's shape became synonymous with flying coolness. Improved versions of the power plant gave the Model 25 yet another increase in performance.

Model 28 featured new winglets in place of the previous tip-tanks. This new aerodynamic technology afforded a dramatic reduction in induced drag which in turn increased the aircraft's potential range by reducing fuel consumption. Model 28 is the ultimate development of the straight-turbojet powered business jet and still holds quite a few FAI records to this date.

The Xtreme Prototypes 20 Series add-on business jets are fully detailed with over 500 parts and 40 animations. The airplanes feature different high resolution reflective textures with bump maps, emissive (night) textures, unique markings, movable control surfaces (movable stabilizer, elevator, ailerons with trim tab, flaps, vertical stabilizer/rudder with trim tab, and spoilers), highly detailed extendable landing gear with taxi and landing lights, fully animated engine turbine and compressor disks, movable main cabin door, and cabin details including cockpit, passenger cabin, seats and pilots.

All 20 Series for Flight Simulator X aircraft are equipped with two General Electric CJ-610, 2,950-pound static thrust, single-spool turbojet engines.

The aircraft display animated visual effects such as engine smoke and contrail effects, aircraft lights (landing, taxi, recognition, navigation, rotating beacons, strobes), virtual cockpit/cabin lights, wing vortices and vapor trails.

Other features include a custom sound package, multiple camera views (external and internal), kneeboard reference tab and check list and a comprehensive 85-page user flight manual in English and French (PDF format).

Each 20 Series aircraft comes with a fully functional virtual cockpit which contains over 800 parts and more than 200 front and back-lit animated gauges, switches, levers, light indicators and flight instruments.

The full 3D gauges have been carefully designed and programmed based on the original analog instruments found in the real business jets. Virtually all gauges, switches, lights and instruments found on each panel are functional and behave like the original ones found in the real aircraft. Aircraft engines and most systems present in the real aircraft are also simulated.

The virtual cockpit allows for complete IFR flight, and features all the instruments, annunciators, displays, switches and knobs necessary to do so.

Multiple VC camera views are provided to help the pilot access switches and other items in areas of the cockpit that are difficult to reach when in the default VC view. Users can cycle through the different views.

The virtual cockpit allows for total 3D immersion into the 20 Series flying environment.
