For the @$&*^! time, who cares what the "full fuel" payload is? It is
totally meaningless.What matters is the payload with enough fuel to fly the same mission. This may be the same thing in your example with the 172 and Turbo Bonanza but the notion of "full fuel payload" is one of my pet peeves. If the plane can carry more than one pilot with full fuel, then the tanks are too small. Mike MJ-2 "Dan Luke" wrote in message ...

Well:
The range on your 172 RG is 600nm according to http://www.risingup.com/planespecs/i...plane280.shtml The turbine Bonanza burns 21GPH block speed to produce 190kts http://justsaytheword.home.mindspring.com/articles.html So the turbine Bonanza needs about 66 gallons to fly 600nm which weighs 444 lb. The piston A36 Bonanza has a useful load of 1400lbs http://www.risingup.com/planespecs/i...rplane98.shtml leaving 956lbs of useful load on a 600nm flight which is roughly 50% more that your 172RG. Presumably the turbine is lighter and the advantage is even greater. I don't know if the 600mn range figure for the 172RG includes a reserve, but even if it does, the Turbine Bonanza has significantly better payload over ANY distance.

The turbine Bonanza burns 21GPH block speed to produce 190kts So the turbine Bonanza needs about 66 gallons to fly 600nm which weighs 444 lb. So it needs 90 gal. to go 810 NM., about 610 lbs.

The turbine Bo' in the article has a useful load of 1160 lbs., leaving a useful load over the same range of 550 lbs.; 100 lbs. less than my 172RG.

I am at a loss as to why the weight of the subject airplane is so high. The
turbine engine itself weighs less. Not having the article, I have to assume that the plane has a lot of avionics and a heavy interior. You start adding radar, SS, lots of radios, cabin entertainment and other gizmos and soon the plane has gained 300lbs. Range is usually the shortcoming of piston to turbine conversions but the Allison engine in the 210 works out well from a range standpoint, so I don't see why the Bonanza wouldn't as well. Is the article availible online? Mike MU-2 "Dan Luke" wrote in message ...

Is the article availible online? The tips add a few hundred bounds. The D'shannon tips are about 100lbs and these things look bigger. |

It's a "Jaguar Edition" 36, so that might explain some of it. Is the article availible online? I can't find it. It may show up after this month's issue is no longer current. http://www.planeandpilotmag.com/ -- Dan C172RG at BFM |

I had the opportunity to fly in the very same plane described in the
magazine today. We went for lunch at Madison, WI, which is around 50 miles away. My first impressions are that it had a lot of power- we were passing pattern altitude by the end of the 5,000 foot runway with a normal climb-out. With normal power settings it cruised about 40-50k faster than a piston Bonanza (187-198k GS) in both directions. The plane is very well equipped, with a Garmin 530 and 430, TCAD, and WX-500 Stormscope, along with fuel totalizer. Except for the panel for the tip tank pumps, the rest of the instruments were pretty standard. The ride was extremely smooth and quiet, and it retained the famed Bonanza handling characteristics- very light on the controls, with both pitch and roll well harmonized. It was much quieter than a piston Bonanza, and flying was a lot lower workload than my Baron. Also, you can stay high and keep the speed up until final- the big prop acts like a speed brake. No more concerns about shock cooling either. The plane also looks cool, with the extended nose and winglets. The turbine conversion and wing tips definitely do not look like they were patched on- the workmanship is flawless, as is the paint job. I'm not sure what the Jaguar interior adds, but everything is tan leather, and nicely done. I haven't gotten into all of the technical details of fuel burn, useful load, range, and endurance yet, but will try to learn about this during the next few days. However, I can say that this is one very nice airplane. (By the way, our friends flew with us to lunch in an RG 172, and even though they left around 15 minutes before us, we passed them with about a 75 knot overtake speed.) |
