Prevailing Winds

PhanTactical Mod Development Team

Prevailing Winds, or Pwinds, attempts to create wind effects on helicopters within ArmA 2. It currently works with all Arma 2 and OA helicopters and with the helicopters within Isla Duala. Wind simulation is drawn from the ArmA weather mechanics. If the ArmA mission has stormy weather, the wind will push helicopters around far more than on a sunny day.

To correct for wind effects, pilots will have to angle their choppers into the wind, just enough to keep them stable. Autohover does not work at high wind speeds, as the helicopter won't be able to manually correct. Urban landing zones become a huge issue, as wind could smash a helicopter into a building if corrections are not made.

Helicopters do not get pushed around when they are touched down. Once the helicopter lifts off the wind takes effect, as it would realistically.

Note that this mod does NOT effect the AI. Otherwise, AI couldn't do something as simple as landing the helicopter at an LZ. ArmA AI don't know how to handle this level of realism (haha).

To wrap up, Prevailing Winds is meant to overhaul flight. Experienced pilots may have to rethink their flying techniques. While previously courtyard landing would be optimal, a pilot may have to consider the wind and his surroundings before attempting such an enclosed landing. Prevailing Winds will be updated with bug fixes when required.

- Pushing about of all A2 and OA helicopters based on wind magnitude and direction.
- Disabled wind for AI, so they can still pilot.
- Disabled wind when touching the ground, so you don't skid off to infinity.

As we always recommend use modfolders to seperate the custom content from the official game content to prevent problems. For different ways to set up your modfolders and use them please visit our FAQ.

When you are using the Steam version you can find a Steam mod installation and activation FAQ here.

Included files:

Place a chopper in the editor, and turn on wind effects via changing the 'Weather' slider in the editor, which is accessed by clicking on the sun icon on the right-hand side (This is called the Intel Menu).
This addon will work on a dedicated server that is not running the addon, and will work on a dedicated server with multiple people running the addon. Only the person who has the mod enabled will experience the effects of the mod whilst flying, unless they are the passenger inside a helicopter.


If anyone understands the effect of wind on helicopters, and would like to help bring more realism to the wind simulation, please let me know. It would be a massive help.
