As mentioned, most users have no contact to airport configuration AT ALL. They don't have to, they just use profiles. Remembering all the keybinds just for the QuickEdit pushback (if you use it rarely anyway) is quite a hurdle for many people - especially since the keybinds are not intuitive (e.g. adding waypoints etc.).
The keys can't be more intuitive than they already are: how you can possibly say cursor keys are not intuitive ?
The ones that might be less intuitive, as you just said, are the waypoints. But the thing is, you don't have to use them very often.
Yes, I keep seeing video tutorials explaining the QuickEdit Pushback, and they all try to use way more waypoints than it's really required, because they are accustomed ( again, old habits makes you lose sight of a better system sometimes ) to the concept of waypoints, so they try to "force" the pushback path to pass through them, which most of the times is overkill, because those aren't really waypoints, they are control points of a spline, which means you rarely need more than 1 or 2, since GSX will fit a curve through them which is better and smoother than one using an unnecessarily number of waypoints.
And even these two can be placed automatically, because I keep seeing tutorials forgetting about the N.1 most useful function in the whole QuickEdit editor: the automatic placement of waypoints with NumPad5, which places two waypoints in a sensible position that will also achieve automatically the result of having the pushback perfectly aligned with the airplane at the end of pushback.
So, in 99% of the situations, the only keys you really need are:
- Cursor keys to move the airplane pointer ( obviously intuitive )
- NumPad 1/3 to rotate the airplane pointer.
- NumPad 5 to create the automatic way points.
And that's it. This will solve almost every case the automatic Left/Right pushback couldn't already solve by itself.
It's not just about being used to another way - it's also that for many users editing the pushback via mouse on a 2D screen is much more intuitive and easy. No need to argue against that, it's just personal preference. Saying that they are just used to it is suggesting that their opinion is wrong - it is not
Where, exactly, I used the term "intuitive" or "easy" ? I never said that. I said that, AFTER YOU LEARN it, the GSX way is better, more accurate, more useful to check actual obstructions and even quicker. In fact, the very sentence "after you learn it", clearly indicates never tried to pass the GSX method as "easier" or "more intuitive".
The little time you spend learning how it works, will save you more and more time, the more you use it.
