Hummer vs Skylane

I just realized that my Skylane gets about the same gas mileage as a Hummer.
I burn about 13gal per hour and go about 130 knots... 10nm per gallon, or
11.5 miles per gallon. Now granted I am going in a straight line, and 3
times as fast, but still that is awful mileage. Now my old Cessna 140 did
a lot better, 105mph at 5gph... more like about 20 miles per gallon.

Can anyone boast better mileage?

My 5.9L Durango gets about 13.5 avg statute mpg (mix of hwy + city).
My PA28-180 gets about 145 statute mph on 10gph = 14.5mpg, so the
plane gets better mileage than the truck. Too bad 100LL is $1.00
more expensive than 87 octane. (I just paid $4.04 last week, ouch).

Drag is proportional to speed squared, so the faster you go - the more
difficult it is to maintain a good mpg.

Having said this, many of the glass homebuilts have impressive drag
coefficients and as a result, fly fast on little gas. The Quickie
Q200 and Super Pulsar are both examples of planes that can approach
180mph on 6gph = 30mpg.

I paid $4.21 at TraJen in Austin last weekend. And that was the
cheap gas on the field - Signature was $4.40.

They only charge that much because the weather is so
nice and cool here :-)

You could have refueled in Georgetown (KGTU) at $2.75 per
gallon, or at Burnet (KBMQ) for a bit less than that.

WHEW!

Did you get taken!!!

Its still $2.85 most places around San Antonio -- just south of you.

In fact, I tanked at New Braunfels two days ago at that price. It
might be worth your while to fly south a few minutes and get gas at
KBAZ.

Yeah, but we were headed for a book signing 12 miles from AUS.

At the present price of auto gas 2.20/gal and Avgas $2.91/gal flying to
work is about a wash over driving. I save and hour a day.
Cost for fly Fuel only $17.46. Cost to drive Fuel only $14.14.
I fly to work whenever possible.

But the 182 looks good while converting all that money to noise. The
Hummer is a god awful looking contraption. More befitting a low wing
driver.

My low wing Arrow gets about 14mpg at 75%, 100 ROP, 175 mph. If I'm
willing to accept 150 and run LOP, I can get it all the way up to 16
mpg. But I don't own a car.

The best solution is always to have tailwinds.
