Part of Arma 3's recent roadmap includes more regular updates to the game's dev branch, introducing all manner of tweaks and new tools to the terrifying military simulator. As of this past week, that includes new helicopter physics.
Using knowledge gained via Bohemia's own Take On Helicopters (my title for this post is really very clever), a new set of flight physics have been introduced which "is more complex, taking into account things like a helicopter's construction, the weight of fuel/ammo, wind influence, stress damage and much more besides." There's a video of the new model in action below.
"Wind influence" is what calzone pizzas enact upon me. Yes, that's a fart joke.
The post on the Arma 3 development blog goes into greater detail about 'rotorlib integration'. All of the work is being done in advance of a new piece of DLC, Arma 3 Helicopters, and so part of the new system is making it flexible for players of different skill levels: the advanced flight model is off by default, and even if you turn it on you can enable helpers or turn off certain functionality like "stress damage" or "rough landings".
"Rough landings" is another thing that calzone pizzas enact upon me. Yes, that's a poop joke.
