Oh yeah, I’m thinking the feature is cold and dark on the 777 and 747
Cold and dark on 777 is great, but that's not a "new major feature". I think it might be ground service in airports, like push back vehicles, cargo trucks, etc… as developers have mentioned this before.
3) Push back: This needs to be done right. We want the push back truck to have it's own physics simulations so that it will be impossible to have the wheels pointing in one direction and have the truck moving in a different direction like you see in "other simulators". We also don't want to constantly teleport the aircraft during push back "like in other sims". The push back truck should obey all laws of physics while it is attached to the aircraft. We don't have it in the sim because we do not want to just hack this in and cause us a headache later on, we want to do this right. The system for loading physics and the push back truck model should also be able to load e.g. an aircraft carrier or other moving vehicles that you can land on, a glider winch, a tow plane, a fuel truck, etc. Combined all this will take less time to implement than hacking in each of these features. But we're still busy with other important features.
