I'll give you a corporate jet pilot's perspective on this and may clarify some of the things that go on. First of all, the large majority of airline guys spend every flight pulling into and pushing back of a long yellow/white stripe line with a marshaller. Corporate pilots fly into and out of large and small airports some of which are uncontrolled and have no ground communication. Parking ramps at many FBO's is done on a space available principle. We're always parking someplace different and sometimes we park in some weird positions and locations. I've been to the same airport many times and am parked according to the FBO's needs. Also at some of the smaller fields, there are no marshallers and we park ourselves. Also at some airfields, they have parking spaces that are spray painted for C 172 size aircraft so it makes it more difficult for us to get from the end of the runway to the ramp without bending metal. Now I can also say, that we have our share of pilots that don't follow instructions and do what they want, but for me, when I see a professional such as yourself, it makes my job a whole lot easier with you out their doing your job correctly. Keep up the good work.
