I did my first IFR flight last weekend (First one after getting my
Instrument rating).  It was in an Piper Arrow, which I have flown only two
times before.  Sky conditions where 2000 to 4000 overcast with 10sm+
visibility.  I found it harder to fly the plane when "VFR" than when in
actual because of the extra scanning you have to do outside the aircraft.
For the first half of the flight, I was constantly fighting to keep within
10 degrees and 100 feet.  After I got the hang of doing that, it was a
little easier, but trying to learn a new complex plane and do an IFR flight
in semi VFR conditions was a lot of work.  I would recommend to anyone that
is new to Instrument flight to go up with a safty pilot and practice.  It is
completely different than flying with the hood or foggles.

BTW, in the last 4 months, I have flown 6 different models of aircraft.. I
find it very rewarding and would recommend it to anyone.

When outside IMC, even when IFR, you are _supposed_ to be looking out at
the scenery and almost never at the instruments.  When not in a cloud,
you are just as responsible for see-and-avoid as any other VFR aircraft.
Therefore, above an overcast, you should be doing full traffic scans
as usual, occasionally glancing in to check heading,altitude,navigation
against your IFR clearance before going back to the traffic scan again.
If you don't do that, you're setting yourself up to be a midair statistic.

In FlightGear, do something like ...
shift-4 [traffic] shift-7 [traffic] shift-8 [scan] [traffic] shift-9
[traffic]
shift-6 [traffic] shift-9 [traffic] shift-8 [nav]  [traffic] shift-7
[traffic]
... and repeat.  Also, when you exit a cloud, whether side, bottom or top,
do a full traffic scan that includes shift-1 and shift-3 before much else
because you've got about 20 seconds before collision with a legal VFR
aircraft
and a lot less for someone who is cutting corners ... or if you're in class
G.

And, yes, maintaining IFR tolerances when in bumpy VMC is very busy work.
