I would like to propose that infinite flight add the ability for a pilot to decline a takeoff or landing clearance. As it is now, a pilot could be violated for not following the direction to takeoff or land.
In meat space aviation, it is common for pilots to decline an takeoff, especially an immediate takeoff clearance. There are many many reasons why this can happen. Maybe the pilot is uncomfortable with how close another aircraft is. Maybe the pilot is flying a heavy aircraft, and needs to do a run up at the end of the runway before releasing his brakes. Likewise there are many reasons why a pilot would decline a landing clearance and execute a missed approach… So I would like to suggest that infinite flight add the decline button to the interface. It increases safety in our virtual world. It’s also not too hard to program. If you like it then go for it.
