Blues is Life

Onward to KGCN. I figured since this was a longer leg, requiring switching of fuel tanks that Duenna would have problems...it did. I think this seems to be the main issue, unburned fuel being returned to the left tank. I'll post this question to the A2A folks and see what they say. Fuel weight: 703.0 lbs (-381.0 lbs) 381*.06=0:22:52 Summary: Direct distance: 236.1 nm

Back in the ponyplane for the next leg to KTEX. No issues with Duenna. Fuel weight: 922.0 lbs (-174.0 lbs) 174*.06=0:10:26 Summary:

Q'PLA Bill!!:salute::icon29:

Short hop over to KASE, again only used left tank, no issues with Duenna. Fuel weight: 1031.0 lbs (-71.0 lbs) 71*.06=0:04:16 Summary: Direct distance: 25.8 nm

Back in the saddle to KLXV. Short trip, only used left tank, duenna played nice this time. Here is the data for KLXV. Fuel weight: 961.0 lbs (-135.0 lbs) 135*.06=0:08:06 Summary:

I read over at A2A, that while on an F-104 research trip, Matt Younkin's Beech 18 was at the same airport. It was 'looked at' by certain A2A staff. :mixedsmi: Whether this means anything or not, time will tell, but one can only dream of a fully accusimmed Beech 18/AT-11 package.:salute::engel016:

Here is the trip to KBDU. I flew a pretty smooth trip, tho I did fly mostly from the right tank. The P-51's unused fuel is returned to the left tank. I am beginning to really think it is this returned fuel that is causing Duenna errors. Anyway here is the data. Fuel weight: 602.0 lbs (-150.0 lbs) 150*.06=0:09:00

Back at it after a few days off. Here is the trip to KSBS. Everything green this time, started from a cold airplane, no 'extreme' maneuvers and Duenna played nice this time. Fuel weight: 760.0 lbs (-335.0 lbs) 335*.06=0:20:06 Summary: Direct distance: 208.1 nm Flight time: 00:48:18

Here is the trip to 36U. This time I threw the old girl around a bit in the sky. Some steep dives, rolls, outside loop, tight turns. Definitely pulled some Gs as you can see from the VC's G-meter. Initially Dunenna didn't seem to care, but apparently later, it had some fueling issues. Interestingly in the error log, the refueling occurred during level flight, and during a shallow descent. Fuel weight: 713.0 lbs (-383.0 lbs) 383*.06=0:22:59 Summary:

Here is the trip to KSUN. Duenna played nice again this time, and again I was mindful of my rate of descent. I think Accusim's modeling of the fuel system really simulates fuel as a liquid, subject to G-forces. I know in the P-40, if I throw a hard negative-G maneuver, I can starve the engine of fuel. Being inverted too long will starve the engine as well. Perhaps a dive causes fuel to be returned to the tank, I don't know. I'll have to ask one of the techs over at A2A. On the next leg, I'll throw the P-51 around in some aerobatics and see what Duenna does. Anyway, here is the KSUN data. Fuel weight: 506.0 lbs (-239.0 lbs) 239*.06=0:14:20

Good for her, that gal has some real cojones to dare sing about real life. :salute: I only hope the country music industry has the courage to support her. I think this 'real life' exists both in the city and country. Sure, there are nice pockets around that don't see these problems, but there are certainly a few of areas out in the country that are poverty stricken, riddled with drug and crime problems. The Blues has been singing about this 'real life' for a long time. Cheers TJ
