Dear Fighter Pilots, Partners and Friends,

We are pleased that our 2022 Spring Flash Sale runs until the 22nd of May at 15:00 GMT. This is your chance to land great savings across most of our range of modules. Take a look!

This week, we bring you the latest development progress on DCS: Ka-50 Black Shark III. We are currently working on the Inertial Navigation System (INS). Read the details of this complex task below.

The BuddySpike server is hosting their first Eagle Dynamics-sponsored “DCS League” event. Starting on the 30th of May, with no registration required, simply join the server when the competition starts and take to the air!

Thank you for your passion and support.

Yours sincerely,

Development Progress

Ka-50 Black Shark III

The Inertial Navigation System (INS) is based on dead reckoning by a double integration of aircraft accelerations that are measured by the accelerometers located on a gyro-stabilized platform. The fundamental property of the INS is the accumulation of coordinate measurement errors over time (platform alignment errors and accelerometer errors are also integrated twice). With the use of INS mathematical models, we have achieved a realistic error accumulation effect, as well as a physical alignment of the gyro-stabilized platform when the helicopter is started.

As a result, the INS-derived location can only be determined with limited accuracy. The error in the calculation of coordinates accumulates at the rate of several kilometers per hour and when starting the INS, it will be necessary that the helicopter remains stationary throughout the alignment procedure. Otherwise, a less accurate alignment will lead to an accelerated accumulation of errors. Three different alignment options will be available: “fast” allows you to take off rapidly but it provides low-accuracy during the flight; “normal” and “precise” provide better accuracy with greater alignment times.

When using INS for long flights, correction/fix taking points will be available. Prominent reference points on the ground with known coordinates make it possible to eliminate accumulated errors in two ways: by flying over the landmark, or by using “Shkval” tracking of the reference point located away from the route. Thus, navigation in Ka-50 will become more realistic with the simulation of INS errors that are present in real life.




We are pleased to announce a new Buddy Spike competitive event that is sponsored by Eagle Dynamics. It will start on the 30th of May and run until the 12th of June 2022. You can compete in mixed PVE/PVP matches and fight to take control of the battlespace.

Although it is an individual competition, pilots can work together to achieve better results. There are four prize categories for best pilots: Air-Air, Air-Ground, Multirole, and Support Helicopter.

A prize pool of $5,000 USD with four Ace prizes of $700 USD each is available. Prize money or ED miles is available for the top ten pilots in each discipline. As the competition progresses, you can track your performance using the BuddySpike Gadget. Join the Buddyspike Discord now to start planning your tactics!

Thank you again for your passion and support,

Yours sincerely,

Eagle Dynamics
