The short and painful answer is no. Once you set your arrival time it can't be changed even for the best of reasons. I get around this by
adding about 15 to 20 minutes to my flight time. If you do have an emergency and declare it, go ahead and do what you have to to get on
the ground.

Well yeah I know that these options do not currently exist lol. I was wondering if they seem like possible additions in future updates.
