I imagine that it would also be pretty nasty if the pilot left off
only one cap.  It cannot be easy to handle the plane with one wing
tank full and one empty at circuit altitude -- one good gust could put
you upside-down.

[Flightgear-devel] relative gear/flap sound volume

2002-07-03 Thread Curtis L. Olson

Does anyone have any objections to lowering the relative volume of the
gear and flaps in the default cessna 172?

Regards,

Curt.

 It was a particularly nasty trick on a 172M, which uses an up/down
 toggle switch rather than a slider for flaps, but I caught on when the
 plane wouldn't climb at 70kt with full power.

Next time, look to your left and a little bit up and to the rear.  If
there's a big honkin' chunk of metal blocking your view, check the flap
switch. *huge grin*

The other one I've learned from real experience (as a passenger).  If
while you are looking a little up and to the rear to check flap
status, if you also notice a big plume of something that looks a lot
like smoke coming off one or both wings, land and check your fuel tank
covers.  (And extinguish your cigarettes.)  :-)

Ye gods.  That's why you pre-flight _after_ you've fueled up.  Gas it,
park it and then check it _all_.  I'm amazed you made it back.  It doesn't
take long to suck those wing tanks dry.

In the 172M, the rocker switch doesn't tell you anything (and the
position indicator beside it was, of course, U/S).  In the end, I did
look out the window, which was a non-trivial bit of contortion with an
instrument-training hood on.

Remember to jump up off the floor just before the plane hits the
ground, and you'll be fine.

Could have been plenty in the center tank ...

I would think fuel spraying somewhere near the nacelles or exhaust plume
would be a bigger worry.

That was when I was young and stupid.  The pilot fueled back up,
screwed on the fuel caps, and off we went again.  I should have used
that opportunity to exit the plane, but was too excited about the rare
chance to go flying ... it was a wild ride though ... we flew up to
northern AZ and were buzzing some poor rancher's cattle, or would that
be some rancher's poor cattle.  Anyway we were occasionally pretty
close to 90 degree bank about 50' above the ground.

In retrospect, yes, lucky to have made it back from both flights that
day.  That was the last time I went flying with that particular pilot.

These days I give all my potential pilots a check ride in flightgear
first before I'll go flying with them. :-)

 I would think fuel spraying somewhere near the nacelles or exhaust plume
 would be a bigger worry.

I think they're talking prop light aircraft.  It is especially severe
with high wing aircraft, since you cannot simply look at the fuel filler
ports and trivially inspect them.  Fuel island staff often don't know
how to put the caps on right, and pilots often leave them off to dip the
tanks and get distracted, so forget and take off without replacing caps.

The fuel starts to siphon off as soon as the wing generates lift, which
is creating a low pressure above the wing surface, and I'm told you
have about five minutes before that tank is completely emptied out.
The fuel doesn't siphon out before the lift is generated, so there is
often no indication on the ground (during runup) of a problem.
Given that this corresponds to 7 miles at normal flight speeds and
a normal empty traffic pattern can be as big as four miles around,
it is imperative to declare an emergency immediately and get any other
traffic out of the way.  You cannot afford any delay at that point.

Another fun trick is to leave off the oil cap.  As you're rolling
down the runway and advance the throttle to full power, about
five seconds later you lose all forward visibility as the engine
oil gets delivered all over the windshield (at 30 mph ground speed).

No, I haven't done either of these.  It's amazing what you learn
when working as a safety counselor (grin).
