Self-Loading Cargo v1.6.7.0 Released

X-Plane 12 Websockets API Integration, Inibuilds A350 integration and more....
Self-Loading Cargo v1.6.7.0 has released and brings a host of improvements not least an integration with the X-Plane 12 Websockets API to allow deeper integration with popular aircraft on that platform, as well as native support for the Inibuilds A350 Airliner on MSFS 2020 and 2024.
X-Plane 12 Websockets API Integration
Historically Self-Loading Cargo has been unable to "talk" to the aircraft inside X-Plane at the same level of detail that MSFS allows due to limitations with the XPUIPC plugin used to communicate with the simulator. However with new Websocket API support, Self-Loading Cargo is able to naitvely determine the state of doors, cockpit switches, environmental controls and more for many popular aircraft such as the ToLiss A3xx series, Zibo and LevelUp 737s, Rotate MD80, FlightFactor A350v1 and some default Laminar Research such as the Airbus A330. This allows you to enjoy more of the capabilities of Self-Loading Cargo that were previously only available to MSFS users.
More aircraft will be added in due course and of course you can still use the SLCSeatbeltsXP LUA script to control the seatbelt switch on unsupported aircraft until they're integrated.
This improves on the previous integration which allows BetterPushback support and jetway control made available during the v1.6.6.x branch.
This forms phase 1 of the Websockets API integration - the goal is to remove the requirement for XPUIPC going forwards so more to come.
Inibuilds A350 Airliner
The A350 continues to be one of the most popular aircraft used with Self-Loading Cargo so it was only fair we brought it all together with a full integration - Seatbelt signs, Doors, Cockpit Door, Audio Control Panel, Environmental controls etc are all working with Self-Loading Cargo and as an added bonus the A350 is one of the few aircraft that actually allows its cabin temperature to be read from the simulator, so the independant environmental simulation within Self-Loading Cargo does not need to run ... what you see on the aircraft screens is what your passengers will experience.
