This idea is a additional Autopilot mode. Once it’s activated, your airplane holds in a standard holding pattern, at the present position. This would help, in case you need more time for the planing of your approach, in case you’re approaching a busy airport and the controller asks you to enter a holding pattern or in case something important happens in real life during your flight.
I know, there is a similar feature suggestion from 2015. However, since this is 2 years old and already closed and since there were a lot of changes in this simulator by now, I want to bring this up again. It is very difficult creating holding patterns just by using HDG or the current navigaton functions.
This mode would help the pilots and the controllers as well.
