Hardware in the loop simulation, button disappeared from Missionplanner


I’m trying to achieve hardware in the loop (HITL) simulation using “X-plane 11”.
Here is the doc :

However the hardware in the HIL button isn’t there anymore in the new UI:


I have been looking for HITL firmware image on this page without success either :

Any idea where I could find this HITL firmware?

ArduPilot hasn’t supported HITL since we transitioned away from 8 bit hardware as far as I know. The key reason for that is that you can’t feed the EKF fast or consistently enough over USB.

okay thanks for the info!

Could a mode for sending the servo positions over USB from SITL be done?
