Don't forget, the more people you bring with you makes it an even better deal, you and a significant other want to take your trip, you're looking at 2 grand. You plane- same cost, and an even better deal per seat. Can you tell I've made a similar pithc before? |

George,
What is the total time each way, general aviation and airline? Figure in the value of your time as well, unless it is a pleasure trip, and sadly, it's almost always cheaper to fly the airlines when you by yourself....I can only justify general aviation travel when it is to a remote location where airlines requires a long rental car drive and the distance is under about 500 miles. When flying on business, I have to calculate the cost of the travel as well as my time, and I generally can't justify taking the more expensive route. If more than one person is involved in the trip, general aviation may become cheaper. Then, if someone is going with me, it's usually cheaper to take g.a. aircraft. If two or more are going with me, we always beat the airline fares by a fairly wide margin, even using a twin. With airfares from Grand Rapids to Denver, round trip, of under $300, I can't even begin to compete with a g.a. airplane. On short notice, as you pointed out, the airlines get more expensive, but if I'm trying to rent on short notice, it's rare I can get my hands on an airplane. Then again, if I can, here in the Great Lakes area, I use a twin when going over the lakes, so the rental rapidly exceeds the cost of airline travel, again unless I'm going to someplace out of the way. All the best, Rick "G.R. Patterson III" wrote in message ...

With the advance time you have to show up for security and such, I can make about the same time or better. United is fastest at 4 hours from takeoff in NJ to landing in TN, but I'd have to be at the airport at about 5am for that flight. Delta is 4.5 hours leaving mid-morning. Continental is 6 hours with two changes. I take about 6.5 from takeoff in NJ to landing in TN.

With 62 gallons available (with reserve), the numbers a 75 percent 755 nm, at 65 percent 820, and at 55 percent 870. Sure looks to me as though reducing the power setting increases range, as does carrying more fuel. Bob Gardner I suppose the lesson here is that compensating factors for SOME aircraft can negate the theoretical advantages for different settings. The engine in my case was leaned to peak rpm in both cases. for the guy who asked the original question. doing your research certainly pays. Stealth Pilot Australia. |

news ![]() I suppose the lesson here is that compensating factors for SOME aircraft can negate the theoretical advantages for different settings. "Compensating factors"? Such as, for example? In your particular case, I can well believe that you found the same fuel consumption at 114 knots as at 70 knots. However, that simply means that you selected the wrong airspeed for best range. Your airplane is not immune to the laws of physics. Pete |

Pete never hinted that it was immune from anything. it is just a Wittman W8 Tailwind. in my case pete the engine firewall forward is a standard cessna 150 installation. it behaves a litte differently from a cessna 150. the overall performance of an aircraft is the result of the performance of a lot of its component systems. selecting one in isolation wont necessarily give you a clue as to the final figures for the overall aircraft. btw I wasnt making any attempt at best range. I was merely flying across 300 miles of desert with a chap in a piper cub for moral support. you do assume a lot in some of your comments. now instead of leaping down my throat can you give the guy who asked the original question some assistance in selecting a suitable aircraft?

... never hinted that it was immune from anything. True, you didn't hint at it. You just came right out and claimed it. Bob wrote "the range for any aircraft is dependent on power setting", and you wrote "my experience doesnt [sic] support that". When in fact the range for any aircraft IS dependent on power setting. Bob's statement was somewhat inaccurate in that 50% power may or may not produce best range, and may not even be better range than normal cruise. But it's impossible that your experience would contradict that the range is dependent on power setting, because range DOES depend on power setting. [...] the overall performance of an aircraft is the result of the performance of a lot of its component systems. selecting one in isolation wont necessarily give you a clue as to the final figures for the overall aircraft. The basic aerodynamic characteristic -- namely, the fact that there's a L/Dmax, and that flying slower or faster than that speed causes an increase in drag -- is immutable. The specifics may indeed change based on "the performance of a lot of its component systems", but the fact will always remain that there will always been a speed at which the least drag occurs, and that flying above or below that speed will result in more fuel consumed for the same distance. btw I wasnt making any attempt at best range. I was merely flying across 300 miles of desert with a chap in a piper cub for moral support. you do assume a lot in some of your comments. Such as? All I have done is disagree with statements that YOU MADE. I made no assumptions, I took your false statements at face value and explained why they MUST be false. I never said that you were making an attempt at best range. What I said was that your experience could not have contradicted the FACT that range depends on power setting. now instead of leaping down my throat can you give the guy who asked the original question some assistance in selecting a suitable aircraft? His question is far too broad for any answer to be useful. I tried to make a sensible reply when his first post showed up, and found that there was not enough information in his original question to provide any concise answer. I doubt he was looking for the three-page reply it would have required, nor did I have any interest in spending that much time writing such a reply. IMHO, he has been provided plenty of *accurate* information in this thread -- your own posts notwithstanding -- to inform him regarding the issues specific to range, and a few different types of aircraft that might suit his needs. His budget is going to be the limiting factor in any case, and with only $40K to spend, none of the aircraft he might consider is going to go all that far with one fillup. Pete |
