CowanSim H125/AS350B3e v2.0 Updated Release

The CowanSim H125 v2.0 is our newest edition and is now available on PC and Xbox. At Cowan Simulation we strive for perfection and continuously update our fleet using valuable feedback from pilots around the world. The H125, and subsequent releases, will continue to be developed using that valuable information. Please remember that updates take time. All good things take time. :-)

CowanSim flight models are pilot tested, approved and developed with the Microsoft Flight Simulator SDK. No external flight model/dynamics or programs are used to provide a seamless user experience.

The throttle on this model can be mapped to your hardware. All other bindings are functional as well. This helicopter uses persistence code to save your weight and balance settings, as well as all visible options/models, for your next flight. You will need to set the weight and balance options when the helicopter is loaded, and when the flight is started by using the menu bar weight and balance window. Please read the manual that comes with this helicopter, it will answer a lot of your questions and has a clear explanation for all hardware bindings. The manual is located inside of the package folder. For your convenience (and for Xbox users), there is an online manual and checklist that you can find at: https://CowanSim.com/manuals-checklists/

The H125 comes with 100 liveries, and an easy-to-use paint kit is provided in GIMP and Adobe Photoshop formats. A Blender model is also provided for all the 3D painters out there.

Thank you for the support!

The H125 is a single-engine, light-duty civil utility helicopter manufactured by European rotorcraft producer Airbus Helicopters. Its main rotor system has three blades and it uses a 2-blade anti-torque tail rotor. The helicopter accommodates up to six, including pilot.

France’s Aérospatiale developed the initial platform, and based it on their Alouette II and it was subsequently produced by Eurocopter. Called the AS350 Écureuil (Squirrel), the rotorcraft took its maiden flight on June 27, 1974 and was introduced in 1975. The H125 has seen a wide variety of uses, both commercial and military, and is renowned for its high density altitude performance. One touched down briefly on the summit of Mount Everest (29,030 feet above sea level) in 2005, and a number of others have landed (and then re-launched) from the summits of other notable high mountains throughout the world.

The H125, which has a fuselage length of 35 feet, 10 inches and a rotor system diameter of 35 feet, 1 inch, is powered by a Turbomeca Arriel 2B turboshaft engine that produces up to 950 shaft horsepower at take-off. The helicopter’s light weight (2,588 pounds empty) combined with the high-output powerplant and 3-blade main rotor system gives it its legendary performance. It has an in-ground effect hover ceiling altitude of 13,250 feet above sea level, an out-of-ground effect hover ceiling of 12,600 feet above sea level, and a maximum flight altitude of 23,000 feet above sea level. It has an endurance of 4 hour, 30 minutes, a cruising speed of 160 miles per hour, and a range of 390 miles.

The Airbus Helicopters H125, which features a utilitarian cockpit that grants exceptional visibility, is a favorite of rotary wing aviators. Efficiently designed, this machine is a workhorse, whether at sea level or thousands of feet aloft.
