Hello Pete, I fully agree with you, I have also noticed that sending many key events through "trigger_key_event" disturbs the acceleration feature. In addition, any key sequence, such as E 1 or E 2 to select an engine, does not work any more. But I have a problem with this. I am developing an FMC, and it updates the autopilot heading as often as possible so that the aircraft follows the route accurately, and I use "trigger_key_event" for this. Is there another way to do this? What is the minimum interval of time between 2 trigger_key_event? Thanks in advance for any help !!
