Takeoff distance calculations?

Hi!

I fly a Piper Arrow 180 hp from 1968

Anyone have a spreadsheet or programme to calculate takeoff and landing
distance letting you input weights, pressure alt, temperature?

Frode

What's wrong with the tables in the flight manual?

My God! Its a slide rule! Toys for Luddites! We shall rise again! :-)

I hope so, I've got a dozen or more circular slide rules,
several regular engineering slide rules, and even a Curta
calculator. The Curta is a hand cranked mechanical
calculator that looks like a hand grenade. Certainly a nice
HP or Ti calculator is faster and more accurate, but harder
to use in flight.

If you want to roll your own spreadsheet, here's all the calculations:

post it, if you do a spreadsheet,

I don't, but you do. Check out the POH that came with the aeroplane.

A 1968 POH includes a spreadsheet or computer program?

Wow. They sure were ahead of their time.

A 1968 computer would probably be bigger than the airplane. G

Yeah, and I can never get the weight & balance to work when I bring that
darn thing along....

No POH with the 68 Arrow I'm afraid, but only an "Owners handbook"
Piper didn't start making POH's until a few years later, or so I've been
told.

Anyway, I'm all for paper, eraser and all that analogue stuff of yesteryear
and next year, but it would be fun to be able to calculate light the Boeing
drivers do the excact "estimated" runway distance needed.

(excact estimated, can I say that??)

Anyway, the Owners handbook has a few diagrams, but the resolution for all
the graphs I've ever seen in various other POH's aren't too good.

They give you a general idea, and there's lot's of interpolation going down.
Now, I'd never base a take off down to cm (or inches for you yanks) of
available runway, but putting in a couple of figures into the PDA and
getting a figure back out is an interesting idea to me.
I can always grab the paper version and try to make a more or less straight
pencil line down the graph, but what the hey, the PDA is sitting there, so
an axact figure is possible, and I'm not scared by excact calculations.

:-)

Just another thing to put into my PDA and fiddle with while waiting for the
weather to clear up....

Frode

Yeah, but you won't need to look for a tie down point!
