Hi,
regarding speeds to fly - I use my LX5000 for speed to fly indication (beep
sounds) and therefore I set my best guess for MC at the LX5000 (Cambridge
etc). XCS I use with a safety MC value (higher, than the MC in the LX)
with Vers. 6.0.10 (old solver) to give me conservative values of AltRequired /
Arrival Height. While comparing the arrival heights of the two instruments it
gives me a nice redundancy (using even two GPS sources, Flarm and LX) and ease
of mind.
But again, I understand not everyone flies that way or has two instruments -
therefore please please make the solver use configuable.
Thank you guys.
Cheers,
Sascha

No, you're certainly not alone. I've been trading email with JW privately this
morning.
Ramy, I agree with everything you've said here. I fly the same way.
FWIW, I never use a PDA for final glide... there's too darned many ways to get
it wrong and XCS seems to be exacerbating the trend here. I rag on other
aspects of the 302/303, but one thing it does pretty well is calculate a glide
to a turnpoint. It will also do a final glide with HW/TW component wind which
is *really* useful. and yet to be picked up by XCS.
Another thing I pretty much never do is take speed to fly information from any
instrument. You understand why!
There's a critical need in soaring software to separate speed to fly from glide
calculation that so far hasn't been met by anyone. It is often the case that
the fast (and safe) way home is Mc 1 or 2 speed to fly and Mc 3 or better on
final glide. Likewise, speed on task need not be calculated by your speed to
fly Mc setting.

After using XCSoar for a while I am very impressed with it but at the same time
surprise that it assumes that everybody fly according to MC theroy and with pre
defined tasks. Most pilots I know, which are serious XC pilots, do not set
tasks and do not fly according to MC theory, which is way overrated. In most
place in western US you will want to fly at low MC to stay at the sweet spot
above the mountains and near the clouds. But it looks like XCSoar insists that
if you don't fly according to MC you can't go anywhere since you can't climb,
and that if you fly for OLC than you also have a task pre declared.
