C172 Flaps up or 10 degrees for takeoff

An interesting dilemma.
The manual for the 172 N tells you that 0-10 degrees is acceptable for
takeoff. However it does not tell you what affect it has at low altitude
300 feet MSL Density altitude around 2500 MSL. It only states that it
will have a detrimental affect at high altitude on a hot day. It also
does not give an airspeed for Vy flaps 10 degrees.

In talking to another pilot who has an 172 L has states that his manual
says if 10 degrees flaps are used it will decrease ground roll and
decrease climb rate. Having an overall detrimental affect.

The only definitive number the 172N manual states for flaps 10 degrees
is Vx.

First hand experience seems to confirm what the 172 L manual says.

What do you all think?

Training

Too many people start out in aviation without any idea of what to
expect or with too many options and not enough information. They make
their training more difficult, costly and frustrating than it should
be. Our site is designed to help you begin and finish your training in
a way that best fits your goals and ambitions.

Mild Aerobatics

During primary training, many moons ago, I was growing frustrated with the
sedate nature of our flying, so I asked my flight instructor (Bob — a guy
with 20K hours in every known flying machine) when we were going to get to
the "fun stuff"?  He didn’t know what I was talking about, so I told him I
wanted to see what these things could actually *do*…

At which point he smiled that crooked smile of his, and proceeded to do a
wing-over with a recovery out the bottom, going the opposite direction!   I
was whooping and hollering for more, but he just went back to our lesson for
the day….

Nowadays, Mary and I are very cautious in our Pathfinder, rarely exceeding
45 degree banks, and never pulling more than mild G turns.  Mary hates steep
banks (except in a Super Decathlon — then all bets are off!), and the most
rambunctious thing we ever do are "Up-Downs" (as the kids call them), which
is a firm pull up with a steady push-over at the top that induces negative
Gs in the back seat.

Just curious — what do you guys do with your spam cans?  I’ve seen video
from inside a Cessna that shows a guy doing some pretty radical maneuvers,
but in real life what’s the most you push your aircraft?

EAA Questionnaire?

I just received (and completed) my emailed EAA Airventure questionnaire.
Anyone else get one?

Somehow they knew that I had attended OSH, and sent me an email. (I don’t
remember supplying my email address to anyone at the convention, so someone
inside EAA has spent some time cross-referencing records…)

Anyway, one of the questions specifically aimed at North 40 airplane campers
was regarding our opinion of the "camp store" and its selection/pricing.

Camp store?  Did anyone find a camp store in (or near) the North 40 that
didn’t say "Pick N Save" on the roof?   If so, where the heck was it?

After Annual …

Finally picking up my airplane tomorrow after a 2-month annual. Just
bought it in April. It is a ’61, and despite logbook entries that SAY
annuals have been done every year, it was pretty clear the majority of
stuff under the cowl hadn’t been touched in a LONG time. Picking it up
tomorrow. Along with the usual, thorough preflight routine, I plan to do
one or two landings at that airport, come back, shut down and have
another look at everything before leaving to bring the airplane to my
home airport.

Have a few hundred more hours to go before a major engine overhaul, but
just about every part was taken out, scrutinized, cleaned, overhauled,
and replaced. Any tips/advice on that first test flight after that kind
of maintenance, other than the obvious?

From Avweb…

Customs pilots have gone to great lengths to try to keep the F-16s from
becoming involved, to the point of crafting handmade signs with the
emergency frequency on them and waving them at pilots of target aircraft
through the Citation’s cockpit windows. Cox said that in the end, they
just painted the frequency on the noses of the Washington-based aircraft
so the customs pilots could better maintain visual contact (it was hard
to see through the signs).

Gravity Wins Again, Palwaukee Splat!

"The twin-engine Cessna 421 was leaking oil from an engine and losing
power when the pilot overshot a runway at Palwaukee Municipal Airport,
hit a building, tore through some shrubbery and came to rest on a lawn
near Hintz Road and Chaddick Drive.

The crash caused extensive damage to the Nedco building’s natural gas
line and sprinkler system, MacIsaac said. Company officials could not
be reached for comment.
Hank Schultz was in the lunchroom at nearby Acco Brands when he saw
through a window that a plane was having trouble after takeoff.
"I just saw it coming up over Wolf Road," said Schultz, a production
manager at the office supplies company. "It was in a stall
position–engine up, tail down. Not in a normal takeoff position. We
see planes taking off all the time, and this wasn’t normal."

Jiffy Lube needs to open some GA shops, JG
