I fly at the assigned altitude, period. *I put my trust in the

I many jets, it's nearly impossible to hold +/-100 feet for any
extended period of time without the autopilot.


Bull****.

It really surprises me on how many things we agree on considering you're
"supposed to be" a notorious "troll". But then all I have to really
base that opinion on is the assertion of several other rather more
obvious "trolls"... Ah me... Life was so much simpler before USENET.
To think, I'd be out there vacuuming the cabin of the plane right now if
it wasn't for this group... :-)

As a matter of fact this altitude offset was something a CFII with
whom I was flying with did routinely. If a guy is on the gauges and
can't hold +/- 50 feet en route I would not fly with him. I'll
continue that practice, and I like the idea of missing VORs by a
quarter mile or so. Not quite sure I can do that with the same
precision I can fly altitude, though.

So in spite of all of the off topic stuff I've come away with a couple
of useful things the past few weeks -- that gentle clearing turns when
entering a pattern is a good idea, as is not directly overflying a
VOR.

RAP is working!!!

Well, it's not a new idea. And, if you convince everyone to do it, then the
potential benifit is lost. So it would be best to not tell anyone, eh?

Plus per 14 CFR 91.159:
"each person operating an aircraft under VFR in level cruising flight more
than 3,000 feet above the surface shall maintain the appropriate altitude
or flight level prescribed below"

What you might have overlooked is that it doesn't say "maintain an altitude
minus 100 feet". If you think it's a good idea, fine - go for it. But it
would be best not to tell anyone just in case someone has a bone to pick,
eh?

Well, no. First, it would appear from what I've read here that most
choose not to hold altitudes as closely as I do, second high winged
airplanes would choose to fly above nominal altitudes. I'll maintain
my practice, and include some of the other ideas that have been
presented here lately, I think the best one that RAP inspired is to
include mild clearing turns when approaching a pattern

He could reduce the risk even more by not getting off the ground.
I must reduce my chances of a midair to near zero by never being able
to hold any altitude perfectly constant ;-)
Well except for when I'm doing the car thing... LOL
