I've tried out the recent c150 updates, and have observed the following
problems:
1) the speeds in the help file and on the specially crafted ASI seem
different from what the real Cessnas have. C150 was an inferior version to
a C152, with all the speeds lower, and same size tanks. Here's what a 1985
C152 book says:
108 rated BHP @ 2550 RPM
2x13gal tanks, 24.5 gal usable -- std tanks
2x19.5gal tanks, 37.5 gal usable -- long-range tanks
max gross ramp weight (taxi) 1675lbs
MGTOW: 1670
MG landing weight: same
wing loading: 10.5 lbs/sq.ft
power loading: 15.5 lbs/hp
Speeds:
KCAS KIAS
V_NE 145 149
V_NO 108 111
[EMAIL PROTECTED]:
@1670 101 104
@1500 96 98
@1350 91 93
V_FE 87 85
Hence the ASI markings are: white arc 35-85 Green: 40-111 Yellow: 111-149
and the red line is 149KIAS.
If anybody has a c150 manual available, please pitch in. In any case,
the current speeds and tanks seem unrealistic.
2) whenever I ask to reposition the aircraft,
fgfs sometime freezes with the splashscreen on, and sometimes reports a
crash as follows:
Position for KSFO is (-122.383, 37.621)
Crash: Attempted to fly under ground.
Playing audio after 500.867 sec: intense ground contact
(this is in response to a 'location on the ground' command, 28R @ KSFO)
Sometimes at the same time I also see the aircraft tumbling backwards and
having its tail going underground, controls held neutral, tailwind never
exceeding 7 knots. Could this be that the model doesn't account for the
pilot's weight?
3) in the cockpit view, I see strange speckles around the yokes, which
keep moving; you may get the idea by looking at a (still) image at

When I'm testing the CVS version, it uses the CVS simgear as well.
All the other packages (plib, openal etc) are debian ones.
