Any W&B calculators that work in 640x480 on HP4700 PDA?

If it can run excel, you can dummy one up pretty quickly.

I'm missing something here. Unless I've completely misunderstood the
context, W&B for a light single is a couple of minutes with pencil and
paper. What's the need for computer gadgets?

Well, no one NEEDS a powered lawn mower either.

It is a matter of convience.

A decent utility is usually faster than pencil and paper and less error
prone.

A graphical display give you a better feel for where you are in the
envelope.

Ones like copilot that are integrated in the planning will show you
your WB on the ramp, TO, and landing automatically, which is a big
plus for some aircraft.

The speed of doing the calculations makes it easier to shuffle people,
baggage, and fuel to get within the envelope.

Well, if you're doing it with pencil and paper you've got the graph in the
POH in front of you anyway, so you know exactly where you are in the
envelope.

Yes, if you have that many options. Like I said, maybe I was missing the
context - if you've got something with lots of seats and lots of fuel tanks
and the option of carrying a non-trivial amount of baggage then that's
beyond weekend local flying in a 172.

Well, yes after you plot your calculations on the graph.

However, if you put the actual points on the graph, you'd better be
using copies or the graph is going to get really tattered after a
while.

I doubt most people do a WB for weekend local flying in anything as the
conditions are probably the same as they were the last 50 times they
did it.

The situations where a WB tool becomes handy is when the brother-in-law
and his wife show up and you need to juggle fuel or if you have one of
those A/C where you can take off within the envelope, burn fuel, and
be out of the envelope.

Some people find such tools handy, if you don't, don't use one.
