Dear Fighter Pilots, Partners and Friends,

Development on the AH-64D module is going well. However, due to progress on the “George” AI and flight control system components, we have decided to postpone the Early Access release to the end of January 2022. This additional time will allow us to further develop the flight control systems, hold modes, damage model, missions, skins and other items. As a token of our appreciation for your pre-orders, we are increasing your pre-order ED miles up to 8,500.

We would like to share progress on the current status of the AH-64D Flight Model. We have achieved a good simulation of the powerplant and flight dynamics behavior when compared to the real-world data numbers. This machine is truly sensational!

Please note that the Steam Autumn Sale 2021 has begun and will continue until the 1st of December. Come and enjoy up to 50% off most of our products. We kindly remind you that our eShop sale will continue until the 6th of December 15:00 GMT.

Thank you for your passion and support.

Yours sincerely,

Eagle Dynamics Team


Development Report



The detailed model of the T700-GE-701C powerplant, its Hydromechanical Unit (HMU), and Digital Electronic Control Unit (DECU) have been developed. This includes the compressor and its hydromechanical unit, compressor turbine, combustion chamber, and power-turbine.

Calculations of the angle of attack on both the compressor and turbine blades allow us to determine dependencies between the power-turbine state (main rotor RPM rise or fall for instance) and the state of the compressor, which in turn affects the behaviour of the power-turbine. This allows our model to closely match realistic behaviour in the transition processes for speed changes, main rotor pitch changes, and anti-torque pedal routines.


The engine, DECU and main rotor characteristics modeling have achieved an accuracy error of 2-3% for documented normal flight parameters and 4-5% for emergency flight regimes and environments (high temp. from 35°С and above as well as high altitude low density regimes).


Engine, Flight and Fuel Pages

The Engine page provides important data on the aircraft's engine torque, temperatures, RPM, and main rotor speed. The Flight page includes heads-down information on the performance of the aircraft with the ability to set important mission flight data. The fuel page includes an intuitive display of the fuel storage, flow and transfer systems.

Please watch the latest video in the AH-64D tutorial series DCS: AH-64D | ENG, FLT, and FUEL Pages.

Autumn Sale

Available on Steam

EDGE 2.7

We recently updated the Steam client. This was done to push the Stable version of DCS World Steam Edition to the latest 2.7.8 version. DCS World modules are currently on sale with more than 30% savings on our most popular modules. Hurry, offers end at 10:00 Pacific Time on the 1st of December.

We hope that the DCS World Autumn Sale will be an opportunity for you to pick up something new and exciting this fall.

Thank you again for your passion and support,
