some remarks from the user point of view. I am currently attending my first
competition (the "Berliner Meisterschaft") and use Cumulus on my N810.
Hardware: it is important to have the internal battery loaded when starting a
task. When connected to external battery with empty internal battery, it
starts charging and is not usable in this state. This seems logical and I just
ignored the fact. So my first competition day had to be done without Cumulus
:-( The LX20 did not show me a restricted area in advance, so I earned some
Next day, I had the N810 loaded and it worked fine for a 5:30 hours flight,
with external battery connected. We had area tasks with 40 km radius for two
turning points. Unfortunately, the area task setting is a general setting, so
also the final destination was regarded as turning point with 40 km radius.
When I was on my final glide, 40 km ahead of the destination Cumulus told me,
the target area was reached and did not do any more glide path calculations.
The airspace warning worked very well, no penalty this time! :-)
I think we need area setting not as a general configuration, but for each turn
point separately. This would allow to give the destination point (that must
not be the airport) a radius of zero or 500m, while the other turn points are
handled as defined by the competition.
I know this is work, and Axel already does load of work. Depending on my job
situation, maybe I can contribute again in this winter. But please comment on
