I remember a while ago that there was a discussion about some properties
of the Cessna 172p-3d model.
I went flying yesterday in a 1964 Cessna 172E w/ a ~145hp engine and a
climb prop. The W&B put it into the utility category, and I flew these
tests about 4000' MSL with an altimeter setting of 30.13
Here's what I found:
1. Left-roll tencency: Hands off 105mph, the roll rate seemed to
be very roughly about 1 deg/sec. The ground-adjustable trim tab
had the aircraft darn-close to being coordinated. A fingertip
touch on the right aileron every 2-3 seconds would keep the
wings level without so much as a conscious thought on my part.
2. Nose-up with flaps: Hands off 80mph, add one notch of flaps:
The nose does indeed shoot skyward.. The aircraft climbed 100ft
and slowed to 60mph before I got nervous and gave it a tap on
the down elevator.
Summary: The model was more accurate than I (a regular but low-time
Cessna 172 pilot) thought. Some of the effects may have been somewhat
exaggerated, but a bigger engine in the simulated aircraft might account
for a lot of it. The "seat of the pants" feel that you have when flying
the real aircraft covers up most of the effects.
Good job!
