Pattern work and airport hops without shutting down are a very common real life practice scenario (I've built more than half of my actual hours that way). How common these scenarios are depends on the pilot type. GA pilots certainly just burn fuel most of the time for practice.
Yes.
I believe there are relatively simply solutions to these:
1. Either allow multiple landings per flight entry (including the nearest airports), or
2. Split the entry if there was a ground touch, at the middle of the ground roll.
For landing challenges:
1. If aircraft changes, definitely start a new flight.
2. If there's a position update that is more than some multiple (say 100x guarding for sim rate) from the previous position based on ground speed, start a new flight (this should cover most if not all repositioning).
Maybe my expectation for Volanta are incorrect. Is this a "logging" and "analysis" tool (along with "something to do" in challenges), or is the plan for it to become a flight planner. As a logging tool I'm looking for something cleaner than Little Nav Map (which logs everything correctly), and to keep my route and path as well.
