When you order the Greyhawk to Land (by selecting this type of waypoint near an airfield), it does exactly that and rather well if I may say so. It also turns off the landing runway, which is also good. But then it continue to the other end of the runway and takes off again, which is rather annoying and unnecessary since you obviously want it to land so that you can either save some fuel, rearm and refuel or what not... Wouldn't it be better if it just turned off the runway and shut its engines down?
