Thanks everybody for feedback.
Tobias, but when XCSoar or your device crashes then you're blind about the
arrival time, right? Or maybe you have some backup..I would like to avoid
buying expensive instrument just to have backup for the AAT calculations.
I've used quite unstable HW/SW configurations with mSeeYou but I never had
to remember the start time and calculate the arrival time in my head. Only
this season I actually realized how difficult it is for me.
Simon, as for reporting crashes as soon as possible I agree. The best are
automated tests in these regard. Also a wide and enthusiastic user base
helps a lot. If considered with my feature request I would say this. The
better is crash recovery, the more people will use the beta versions and the
sooner there will be crash reports.
As for the extensive proposal some of you wrote. Am I wrong to assume that
the only input information into the AA dT/automatic optimization is the
start time and the rest of the task to be flown?
If there is only one last turnpoint and finish to be reached the algorithm
doesn't need to care if you reached the previous turnpoints at all. (or how
far did you go.)
So it needs to know:
- start time
- the task (actually only the remaining turnpoints of the task)
- next turnpoint (go to), the software assumes you know what you're doing
and that you did round the previous turnpoints of the task.
(and of course other stuff like wind, bugs, MC all of which can already be
changed by user)
The task is already remembered between invocations of XCSoar. I'm capable of
specifying the "next turnpoing" and other user values after a restart. The
only thing missing is "start time", which I need XCSoar to remember from the
previous run. I can live with incorrect task speed calculation or other
fancy stats.
I trust Tobias it's not that easy :/. Instead of full solution, would a user
specified start time be difficult to implement?
