As far as the lessons on traffic patterns and the airport environment. I believe it essential for a begin Orbitnaut to understand the fundamentals aviation.
My main reason for disagreeing here is that it adds to learning curve, and isn't needed. Essentially, you are presenting too much information. While Orbiter has some support for standard aviation, it's focus is on spaceflight and I've always thought that should be the focus of a tutorial aimed at beginners. The idea being that we want to make the learning curve shallower - not steeper. Just my opinion, and I won't be offended if you disagree!
Besides given another hundred years we'll probably have vehicles capable of making routine flights to the moon.
This doesn't mean that these flights will be common. It will still be VERY expensive, so flights will be limited to a few each month. Traffic patterns are designed for airports that see dozens - if not hundreds - of flights each day. That kind of congestion simply won't occur at spaceports. Also, conventional aircraft don't need to accelerate to speeds in excess of Mach 28 - so the penalty for carrying "extra" fuel is nowhere near as significant as it is for spacecraft.
I image that making an instrument approach to land on a moon base will probably have similar characteristic as a conventional instrument approach.
I'll disagree. In conventional flight flying in circles doesn't cost that much, especially since these traffic patterns are flown at low speeds (so drag is fairly low). In non-atmospheric flight EVERY change in direction has a large fuel cost - flights will be directed fairly "straight in", and "landing slots" will be assigned before takeoff for "local" flights, and assigned well in advance of landing for Earth - Moon flights. Think if the sub-orbitals in Heinlein's novels, where a flight doesn't even take-off until the landing strip is empty and waiting.
Again, this is all just my own opinion - but it's one shared by many people who have given serious educated thought to how future spaceflight will be handled. The simple truth is that spaceflight has different needs and conditions than standard aero flight, and the rules will need to be different to reflect this.
It is , of course, your tutorial, and I fully support your right to do what you think best. Your opinion is no less "worthy" than mine. I am just trying to give you something to think about.
