flying with different instructors

Bob,

You're absoloutly correct, except that I disagree with your specific
example. :-) Setting your power precisely one downwind (or, at the level-off
just prior to the FAF if you're flying an instrument approach) allows you to
trim the airplane properly for approach, and is the one time I want to see
precision from my students. This makes the correct airspeed much easier to
control, and gives you much more time "heads up" during the rest of the
approach to land. You'd be amazed at what a difference a hundred RPM can
make.

Here's an experiment that seems to work on most light singles (and some
light twins). From a reasonable altitude, put in "approach flaps", and trim
the airplane for "approach speed". Then, retract the flaps, and notice the
indicated airspeed. (Usually this is right around the top of the white arc,
but not always. If it's above the top of the white arc, disregard everything
I've said... you'll need to fly the plane :-).) Now, at pattern altitude,
trim the airplane to fly this airspeed while level, and note the required
power setting. Now, bring the power back a bit to start your descent to
land, and put in your approach flaps. Shazam, you'll slow to approach speed
within a couple of knots without much effort, giving you more "look out the
window" time in that part of the pattern where a lot of accidents happen.

In a Warrior-II, 152 or 172P with just an instructor and a student, setting
2100 RPM on downwind, and trimming for hands off flight seems to set the
airplane up for a normal approach speed when using 20-deg of flaps, and the
short-field approach speed with 30-deg of flaps. If you have more people,
add 100 RPM per person. If it's gusty, add about 100 or 200 RPM for the
appropriate speed boost. In an Arrow-II, about 21-inches of manifold
pressure (regardless of RPM) does the same thing. (What is it with "21"?).

Just my opinion. :-)

If your student mistakenly sets the power at 1700 instead of 1800, I hope
you don't get on his case and develop in him a case of
head-in-the-cockpit-itis. I'd rather have the student remember the
position of the tach needle relative to straight up (one o'clock, two
o'clock, etc) and let it go at that. Precise power setting ain't all that
important, yet some students will devote ten long seconds to massaging the
tach to get an exact number because that's what their instructor told them
(if you think ten seconds is a short time, I will gladly stick my finger
in your eye and hold it there for....heck, two seconds be enough to make
my point?).

As a CFI, I think that this can work for advanced instruction
(Instrument, Commercial, and above), but I think it is generally quite
a bad idea for primary students.

The very thing you seem to like about it ("The result is that I've been
able to choose the methods which work best...") can be a major problem
with primary students. By the time you get to the Commercial-student
level, you are a fairly accomplished aviator. You likely feel quite at
home in an airplane, and definionally have hundreds of hours in an
airplane.

Try to think back to when you were a 15-hour primary student. The stuff
that we take for granted is often a major difficulty. It was for me. I
remember being a 15-hour students and trying to remember all the stuff
you had to do before landing, and sometimes looking up and feeling
completely baffled. I know I'm not alone in this.

When I work with primary students, I generally try to teach them one
coherent way of doing things. "Downwind- power to 2000 RPM, abeam the
touchdown point, power to 1500 RPM, pitch for 80 knots. When TD point
is 45 degrees behind, turn base, one notch flaps...pitch for 80....". I
have had students who have flown with different CFIs while I was
working with them. These other CFIs (one was a CFI in training) are
certainly very competent pilots and likely skilled instructors.
However,they do things differently...they teach things differently. And
what seems to often happen is that instead of focusing on the task at
hand and using a technique they know and have learned to trust, noow
the student is thinking "Was it 1500 RPM? No....that was Dave. Jeff
likes power all the way out...wait...."

When I start work with a primary student, I structure my syllabus and
training program to lead from one concept and maneuver naturally to
another...I envision the entire training process that I expect to
perform with that student. I know what each student I have knows...and
what he doesn. I know what he is good at, and what he isn't. And I can
use these things to help him become a better pilot. I think that
continuity is very important...and having multiple CFIs gets in the way
of that.

By the time you are working on your CFI or your commercial, you pretty
much already know how to fly...you are perfecting and advancing your
technique...but you already know how to do all the basics. I think that
it is probably reasonable to work with different CFIs at that level.
but not when you're starting out.

Cheers,


Cap

Chief flight instructor and my primary instructor are both gone for
the
week, so I've been flying with whatever low-time, newly-minted
Cessna-jockey
greenhorn flight instructor that answers the phone when I call to
schedule.
I've flown with four different instructors in the last two weeks.

I wholeheartedly recommend this. Each instructor has his own way of
explaining and demonstrating things, (working on complex rating and
commercial, part 141) as well as slight variations of technique and
procedure. The result is that I've been able to choose the methods
which
work best and with which I'm most comfortable, AND check these things
against other instructors to make sure it's right.

The newer guys have a great sense of enthusiasm, and since the boss
is out
of the shop, they've got great information about what it's REALLY
like
flying as a CFI out of that FBO and things like, how many hours one
might
expect to accumulate over the summer flying season.

I've had one instructor who's a Major in the Air Force and learned at
the
academy, one who is a retired Marine and learned in the '60s, one who
is an
Embry Riddle graduate and one who earned his CFI wings from two of
the
others and has only been instructing for a year. The four different
perspectives have made every flight not just practice, but a new
learning
experience. My primary instructor is excellent, but I wish I'd have
been
doing this to some degree all along!
