I thought it was a request for taxi thing.
Not yet, down the road maybe
I also didn’t notice any changes in the taxi. Let’s hope they add something more in the future. as take-off aborts. engine failures. change in wind direction and take-off. The responsibility with various commands (hold position- taxi etc.) to bring the plane to the stand yourself 
Didn’t the devs said they’re doing this too?
@Jax970319 yes something like that
@carlsberg72 I noticed that there are more discussions about taxis. I find 2. Would it be better to put them in a single “new taxi system” discussion to avoid confusion?
