To take your points one by one
1) Interesting, but irrelevant.
2) This statement is kind of self defeating. The sectors you are planning are well within two crew range and yes it does get very expensive with three crew whether the additional guy is pilot or an engineer.
3) Not sure how you work that one out. You have an extra engine which means engine maintenance is 50% higher. Also the engines have much less life in them so replacement costs (in the first few years) will be much higher. When the "modern" aircraft are no longer modern they will be on a par with the L1011 today as far as maintenance is concerned.
4) "the RB211 524B4Is burn 15 to 20% less than a CF50C2" Maybe so but you have three engines burning 80% still comes to 240% compared to two engines burning 200%.
5) Have to say that I totally disagree with this one. Smoother ride...If your in turbulence, your in turbulence. If you are not then the ride on any big jet is smooth.
Cabin air quality, I refer you to
http://www.boeing.com/commercial/cabinair/index.html. Another urban myth crashes and burns.
Your point about ETOPS clearance being earned is a fair one although I think it is an engineering hurdle rather than an operational one. The operational requirements are not too onerous JAR-OPS 1.246. The engineering approval is a bit trickier but is you use a organisation which holds approval then this shouldn't be a problem.
Lauda Air have never operated L1011s. They do operate 767-300ERs. Source... [URL=http://www.laudaair.com/e/ueberuns/geschichte/index.asp.]http://www.laudaair.com/e/ueberuns/geschichte/index.asp.[/ URL]
Now finally I had a look at you web site for L1011 economics. I don't know too much about most of your figures so I will give you the benefit of the doubt except for navigation charges (greater for almost every other type than the L1011) I was under the impression that the charges were based on MTOW.
And the nail in the coffin.
Your fuel figures as far as I can deduce are based on a fuel price of 20c per litre. The best price I can find on the net (after an addmitedly cursory browse) is 67c per litre.
This puts your DOC for the 2000 mile trip up to $145000. For a 767-300ER it is $128000.
DOC per seat, $152 and $128 respectively.
I await with bated breath.
