View Full Version : Plane 172 fun video


January 30th 08, 02:50 AM
Just plane C172 fun :D

I was a back passenger during a precheckride lesson for a student and
was invited along for the ride. Normal takeoff, stall and fall and
Forward slip to no flap landing featured in this video.

Needless to say, being in the back seat of a Cessna allows for a
unique view out the back window for launch as compared to my
windowless Sundowner and the tire (without the wheel pants) on
landing. A stall was tossed in for good measures.

3 clips in one for the prices of 2 minutes 12 seconds of your
time. :D

And not to be lost in the video, in my NON CFI rated opinion....
student is checkride ready

NOTE Student did NOT know I was videoing until after the plane was
put to bed. I purposely did not tell him as I did not want to add to
any distraction factor.

Shucks Jim!

I been in my rear windowless Slowdowner so long, that here I thought
that was the whiskey compass on the glareshield.

Is that the new fangled rear view mirrors of these new fancy dancy
NEWER model Cessnas. Where is the reverse selection for backing up?

Even one better! Less parasitic drag from the lack of ridging of
treads! Better performance!

The better performance depends on whether you want to stop or go... I
have no idea whether the tread would increase drag -it might even
decrease it!

But I would have thought the preflight should have flagged it? It's
difficult to see the tread with spatted wheels in long grass but seal
stainers have no excuse!

It will work. I have experience with the "Flintsone Motorcycle" version.
I broke a clutch cable several miles from home, in the city. Coming up to a
stop light, I would pop it into neutral, with no clutch, of course. When
the light turned red, I would beat feet to get it rolling as fast as I
could, and with enough speed, it would not stall when I slammed it into
first gear.

Although it would involve cutting a hole in the bottom of your airplane, it
would make stopping in cases of brake failure possible, and make your
backing up an easy affair. Look, I have invented a new safety feature!

I won't even charge you for using my patent pending, or for the paperwork to
modify your plane! ;-)

There is a tape you can get that will do just that. You can glue it onto
your prop as well.

And yes Larry, it IS legal

I just watched it again. I can't believe he made it between the two trees on
the dirt road. Guy's got balls where his brains need to be, but, he knows
how to keep it on the centerline.

Yeppers. It is called turbulator tape. I have never heard of using on a
prop, but most of my time is in gliders. You can buy the magic stuff here:
(About halfway down the page http://www.wingsandwheels.com/page29.htm )

Yeah, the inventors had it on a prop, alright. there was an article about
the stuff in Sport Aviation about ten yeas ago. You had to cyano it ot the
prop and apparently it was hard to keep there. A little rain and t was off.
They advocated putting it on all the struts and gear legs, to. Claimed
considerable performance increases.

Doesn't look like he knows what his feet are for, though. A little hard to
be sure since my as wasn't actually on the seat, but I got a definite
sensation of being driven around as opposed to being flown around. Made me
kinda nauseous!

As an instructor, I couldn't help noticing the length of the
float on landing, and the tiny pitch change after landing. I think,
based on the little I could see, that the approach was very fast, the
pilot flared very close to the surface and floated in ground effect
for a thousand feet and touched down still fast and therefore flat.
It's a common problem in flight training, and often the instructors
just let it happen. Many of them do the same thing. And the ditches or
fences at the end of the runways continue to claim airplanes.

Dan,

Not mentioned in the video, this was a "no flaps landing".

Sitting in the back seat, I couldn't see over the glareshield myself,
so I know he had a **reasonablly** good flare. Hopefully this clears
up the higher speed over the runway and account for the longer float
over the runway.

I am NOT a CFI, but from my observations, I thought he did a good job
keeping the nose off and not rushing the plane to ground. (I.E. allow
the plane to settle on it's own while bleeding the speed off)

As the video does indicate, the stall horn was sounding when the wheel
did touch terra firma.

OK. I was using the available information. But the float was
still really long, and even with no flaps it could be shortened
considerably. Maybe when the student gets into commercial training, if
he decides to do that.
I'm an instructor as well as a mechanic, and see first hand the
damage that sloppy landing technique does to the tires, brakes and
nosegear. Much of it is due to approaching too fast for the
configuration, not flaring until in ground effect instead of getting
the power off and lifting the nose to kill excess speed before
reaching ground effect, and then allowing the airplane to land very
flat, often on all three wheels at the same time. The high speed can
bring on nosewheel shimmy, which tears things up (including nosegear
linkage, radios and instruments), and if the student is doing short-
field landings he'll drag the tires trying to get stopped. There's
still way too much lift at those speeds and no weight on the mains.
I often have the stall horn sounding while still at five feet
above the surface. It'll sound at 5 to 10 knots above the stall, and
that's a stall speed out of ground effect. Stall speed drops a little
near the surface, so there's still some safety.

*smile* for experienced pilots, absolutely agree, but for a
precheckride pilot, my opinion that was pretty durn good. Based on
your input, I have updated the video information so others know.

Yep, agree, my kind of landings.(plenty on my You Tube channel) but a
random sample below.

http://www.youtube.com/watch?v=rh05cgtBtSY stall horn on for 4 seconds
http://www.youtube.com/watch?v=7nuoH7QasqA stall horn on solid for 7
seconds
http://www.youtube.com/watch?v=HR_CN8112J8 stall horn going for 5
seconds.

IFR is a different beast of course asn 90 knots down to DH and losing
that speed will cause more float as I trim to lose speed with one
notch flaps on landing.

My flights are in a 1976 Beech Sundowner.
