Today was my first first "real" flight lesson. I met Brian at
noon at the flight center in Norwood. Beautiful day. Lots of
sun, nearly no wind at all and just at about the freezing mark. I
couldn't ask for a better flying day.
When I signed up for the lesson I decided that I was going to
train in the Piper Warrior instead of the 172. I just felt more
comfortable in it.
Last night's weather was kind of crappy so the wings and control
surfaces of the plane were covered with ice and there was a bit of
snow stuck to parts of the plane as well. On a day like today the
easiest way to clean it off is to let the sun do most of the work.
We had to turn the plane around by hand and let the sun bake the
ice off the wings. You could just knock it off easily at that
point. (Side note: I love being able to move the plane by
dropping all of my weight on the back of the plane and seeing the
front wheel just come off the ground. On the other hand, maybe I
just need to eat fewer cheeseburgers.)
Pre-flight: learned about the "tabs" in the gas tank. They
indicate at least 17 gallons in that particular plane. Got to see
some water in the gas since the tank hadn't been full overnight
and some condensation built up. Went over the control surfaces
and learned what to look for to make sure they were operating
properly. (The ailerons are held on my frightningly small pins.)
Learned what to look for in the landing gear and brakes (no leaks,
please!) Also, check the engine oil to make sure that it looks OK
and there's at least 6 quarts.
Got into the plane, went through pre-engine startup. Took a while
to get the engine started and it was running rough. Let it run
for a bit to get it warmed up. Tried to bring it down to 1000 RPM
for the magneto test and it was running like crap. You
could hear it missing all over the place. At least one cylinder
was missing on almost every cycle. There was no chance that the
plane was going to idle. Tried to run it for a while and see if
it was just some ice or snow causing problems. Leaned it out and
tried to get it to idle. It ran really rough for a while and then
just stalled. No dice. Plane broken. Oh well.
Sadly, there were no other warriors available for practice at that
time so Brian and I did some ground work instead.
We went over strategies for changing from steady flight into
climbs and then leveling out again. Same with changing from level
flight into descent.
Initiating a climb is pretty easy:
- Set pitch
- Set power to full
- Set trim for the climb
Leveling off is a little more tricky because you need to start
levelling off before you get to your desired altitude. You do
want to start setting the pitch before changing the power so you
build up a little bit of speed to get back up to your cruising
speed. However, this is done pretty quickly so you don't build up
too much speed so this is really one smooth operation.
He gave me a rough idea of how to guess when you wanted to start
coming out of your climb to end up at your target altitude. If
you're climbing at 500ft/sec and you expect that it will take
about 5 or 6 seconds to come out of the climb, you will want to
take 10% of that value. So in that case you want to start coming
out of your climb about 50 feet before your desired altitude.
You really want to return to level flight at your original
cruising speed, if possible. Anyway:
- Set pitch
- Set power
- Set trim
Descending is somewhat different and different types of descents
require different kinds of power and pitch settings. When you are
starting a descent, you usually follow the following steps:
- Set power
- Set pitch
- Set trim
Sometimes when you are doing a cruise descent all you have to do
is change the power setting. The nose will dip slightly as a
result of the power change and you might not even have to change
the trim. However, other kinds of descents require you to change
your pitch and trip. For example, an approach descent (I'm not
sure but I think this is what is called a "Mushing descent" in
S&R) you might have to change both the settings.
Pulling out of the descent is very similar to the way you have to
stop an ascent. You want to do so ahead of the actual elevation
according to your best guess with the same types of calculations
listed above. You usually follow the following order, more or
less doing it all at once:
- Set power
- Set pitch
- Set trim
A couple of other notes about the VSI (Vertical Speed Indicator).
It's always a little bit behind in reporting your vertical speed,
however any movement in the needle is accurate. This means
that while you can't always tell exactly what your vertical speed
is, you can tell that you are changing the rate of that speed.
We also talked about where the pitch of the airplane should be for
level flight, descent and ascent. Brian was also nice enough to
take me over to the flight shop across the street and recommended
a couple of books. I picked up a copy of the Airplane
Flying Handbook and the Pilot's
Handbook of Aeronautical Knowledge both of which are published
by the FAA. I haven't read them yet but he says that they are
pretty good and full of useful knowledge.
He also suggested that I pick up a copy of the Illustrated
Guide to Aerodynamics and the Pilot's Operating Manual for the
Piper Warrior. I'll get those soon, I think.
I also got to meet Don, the owner of the local school, and Jerry
who I think is the lead pilot. I'm not sure how to describe them.
They seemed to remind me of two gray-haired italian guys who would
hang out outside one of the italian places in the north end of
boston, sitting in lawn chairs and discussing old times.
I have time scheduled on Tuesday, the 7th. We'll see if the
weather holds up.
