Long Flight

[Terry Carraway]

We were just talking about this today at the airport. A local Mooney pilot said he was burning 11 GPH on a long flight recently. I thought that was wrong, way too high. But the guy who told us that said the Mooney pilot claimed it was because he had the "big engine."

I thought Mooneys were fuel efficient. I could match those numbers in my Bonanza.

The big engines are TIO-540 or IO-550 or TSIO-550 turbo normalized. So similar to Bo. They can pull them way back, but it seems most are running at 16 - 17, but over 185 KTAS, some over 200.

The little engine ones are IO-360 or TSIO-360. I have the TSIO so benefit from the TAS gains with flying high. Down low, I am about the same as the IO-360 planes, maybe a bit more fuel burn due to some losses with turbo.

10.1 GPH

Ouch! I burn at least 11 GPH in my 182 and I'm about to fly it from Idaho to Michigan.

That makes me feel a lot better, Terry.

That's what I was afraid of....2/3 of mine! IHM (I Hate Moonies).

The good news is, the later big engine Mooneys are only slightly faster, but burn fuel at your rate.

(I Hate Moonies) Be nice now Scott!

10.1 GPH

Also EGT/CHTs?

CHTs were under 370. I try to keep them under 380. 343, 362, 366, 340, 364, 319

I don't recall EGTs. The one pic I have of the JPI does not have numbers. I can get them later off the data.

TIT was 1610 on the JPI. Stock gauge was reading under 1400. I think the probe is shot, I am having a new one installed.

What was your fuel burn gph?

BTW, I burned less than 80 gallons BJC to 0W3.

Wow. Nice.

I have done a number of longer flights. 6 hours home to Sarasota. 5.5 from home to Space Coast (yes I did visit Tom). 5.5 home to Rogers AR. 4 Mineral Wells to Denver.

But once you get into the teens, it doesn't make sense to come down unless you are at your destination or need to.
