[Flightgear-devel] C310 Gear Retraction

2002-02-14 Thread David Megginson

I'm having no problem retracting the C310 gear in flight, using
yesterday's CVS version of everything.  It's possible that there's a
problem in some builds, but it's equally possible that people are
letting the plane settle back onto the ground after retracting gear.
Try waiting for a higher altitude first, and see if the problem still
occurs.


All the best,


David

Ditto with a clean build of this mornings FG, SG, and base.

I'm having no problem running with the c310, started the engines, full
throttle, raised the gear as soon as the altimiter needle started to
increase.

Everything seemed good there.

With respect to the c310 flight model math blowing up when you nose
over into a dive:

If I have the blue levers pushed all the way in (low gear) this
happens very reliably.  Push the nose over into a dive and in a few
seconds everything blows up.

But, if I have the blue levers pulled out a bit, I can dive all day
long and things stay well behaved.

So, this would lead me to suspect something in the constant speed prop
code is screwing up at a boundary condition.

Regards,

Curt.

To confirm, it may be worth substituting the c172 prop
(prop75in2f, I think) to confirm this.  That assumes,
of course, that you'll be able to get off the ground
...

  It still happens over here ...

Erik: how high is your altitude AGL before you retract?

  Its' weel above 100 Foot.
  I tried different altitudes, non worked well.

Have you tried different airports?  It's strange that we cannot
reproduce this.  Does the problem occur as soon as the gear are
retracted?


All the best,


David
