If you can determine when the price is high and when it is low it would
be better to speculate in the futures market than pump gas for a
living.


Gee...last week it was $2.60 and now it's $2.99; if you can't figure
that one out, you shouldn't be pumping gas either.


Gee...if it is $3.20 next week, was $2.99 high

Gee, it's Bush's fault that humans are not omniscient except in the
movies.

Oh, BTW: since YOU are prescient, tell us how to deal with it (instead of
sniping from the sidelines so as to bloat your ego). :)

Why is it Bush's fault?

Because he's been waiting, waiting and waiting for the UN to step in, and
they're nowhere to be found.

C182 150mph @ 12gph = .30/mile fuel cost.

Then the value of my Bonanza just went up. If I want to fly at 150 MPH
that's 19 inches and 2000 rpm for a total of 9 GPH. Gas currently at $2.75.

I bought mine to fly and go places. It's at 24 X 24 @ 190 MPH on 14
GPH except when landing and taking off.

I get 199 MPH TAS at 23/2500(75%) on 15 gph or 191 MPH TAS at
22/2300(65%) on 13 GPH.

199 - 191 .......... = 8 mph
15 - 13 .............. = 2 gallons
2 gal x 3.99 ...... = $8

65% to 75%..... = $1 per 1 mph :-)

So now I did some more thinking...

2 hour flight - approx 400 miles
(not counting taxi, take-off, decent, pattern, land)

199 mph vs 191 mph = 16 mile difference at the end of the flight
16 miles takes 6 minutes at 160 mph ...1/10 hour (16x10)
16 miles takes 5 minutes at '192' mph ..1/12 hour (16x12)
[I changed 191mph to 192mph for smoother math]

We know from above post that it will cost 16 extra dollars for the faster
speed (based on 3.99 gallon fuel)

$16 to save five minutes.

But the fast plane is down 5 minutes sooner.
At $60 /hr fixed costs ...that's $1 /minute
....a savings of $5.

So to get there 5 minutes sooner on a 2 hour (400 mile) flight:
$16 fuel - $5 (tach time) savings = $11

$10 = $2/minute for arriving 5 minutes earlier on the ramp, 400 mile away.
Wow.

I'm seeing a "free lunch" if you choose the slower speed. :-)

Ultimately it was a food based problem

So I'm gonna have to find a place that sells avgas around here for
$3.99? It's currently going for $2.75, I'll ask if they'll take $4 a
gallon.

Ouch! Last week I paid $4.60-something in Sacramento, CA.

.... I have fond memories of $2.75 ;-)

It is worth the extra money if it means landing ahead of the approaching
thunderstorm that's about to hit the airport and getting the plane in
the hangar.

But the fast plane is down 5 minutes sooner.

But you are soaked or left sitting in the plane on the ramp until the
rain stops.
