I wonder if anyone can help with me a problem I'm seeing at some airports? Often one departing AI aircraft taxis onto the runway, then stops and doesn't take off. The following aircraft will then be cleared for departure and take off normally, leaving the "stuck" plane on the runway. I wonder if it's to do with where the runway starts are located on some of my afcads, or if it's to do with the width of the taxiway connecting to the runway?
Any help gratefully received.
