X-Plane can drive the attitude indicator, also known as the artificial horizon, from any of three systems. See the article “ Vacuum systems” for more information. Two additional sources of vacuum are now available in X-Plane 11.30. By default, the suction is generated by pumps driven by the engine, so it is dependent on your engine RPM. X-Plane has two vacuum systems per airplane, one for the pilot side instruments and one for the copilot side instruments. See the article “ Propeller feathering systems” for more information. X-Plane 11.30 allows you to select the type of governor to simulate, to accommodate a wide range of different engine types. Depending on the type of engine/propeller combination on the aircraft, the behavior of the governor in case of an engine failure will be different.

X-Plane simulates governors for constant speed propellers that can have various failure modes. See the article “ The X-Plane Anti- and De-Ice systems” for more information. X-Plane also simulates a wide variety of systems that can prevent the accumulation of ice on various surfaces (anti-ice), or get rid off ice that has accumulated (de-ice). X-Plane simulates ice accumulation on your aircraft that will affect your performance greatly. See the articles “ X-Plane autopilot params” and “ Preconfigured autopilots and other autopilot changes in 11.30” for more information. Version 11.30 offers to equip planes with preconfigured autopilots, in addition to the many configurable options of previous X-Plane versions. 11.30 correctly handles prefill options so you will need to review your prefill settings to ensure they are set up correctly. X-Plane 11.26 had a bug where it ignored cockpit prefill settings. For more information, see the “ Attaching 3-D Objects” section of the Plane Maker manual.

Aircraft will be automatically upgraded upon re-save in Plane Maker 11.30. It is attached to the plane in the Miscellaneous Objects screen in Plane Maker 11.30. The cockpit.obj is no longer a special object. If your aircraft loses interior lights upon re-save in Plane Maker 11.30, check your cockpit object’s lighting settings in Plane Maker. Lights attached to cockpit object of type glass (in or out) used to light everything. See the article “ The X-Plane oxygen system” for more information. The new oxygen system is mandatory–if you do not want to use it, override the pressurization system with the new override dataref. It is now possible to equip high-flying aircraft with an oxygen system rather than or in addition to the pressurized cabin, to allow realistic black-out behavior also with unpressurized aircraft. This fix was mandatory for fighter aircraft most other planes should not see a difference. This is the only exception to the re-save rule–it is fixed in 11.30 and is applied whether or not your aircraft is re-saved in 11.30. Stabilizer wash was severely broken for high aspect ratio wing aircraft like fighters in older versions. If you wish to avoid updating your aircraft, do NOT re-save it in Plane Maker 11.30.

Aircraft will need to be updated accordingly. Aircraft saved in Plane Maker version 11.30 will be opted into a few new systems & requirements.
