Realistic flight in Minecraft has never really been implemented. Even the elytra doesn’t take into account true aerodynamics. Minecraft Flight Simulator aim to change all this, by introducing planes that handle like actual planes. To do this physics and aerodynamics are used, taking into account thrust, drag, lift, prop pitch, and much more. Controls are also tailored to provide a simpler means of controlling planes than the current mouse-yoke standard, which allows you to look around as you fly. You can even customize your planes by giving them different propellers and engines, which affect their flight characteristics.
