Hello Guv.
Good(ish) answer.
If you can get fuel for that price…good luck. Further research (off the internet) has revealed that the company I employ to own aircraft for me to fly obtain fuel for that sort of price. They do spend over £100,000,000 each year on fuel though, so have a certain amount of bargaining power. I suppose if you are operating a L1011 you will be in the same bargaining league
The cabin air issue won't go away will it. Quote from Boeing. “This high quantity of supply air results in a complete cabin air exchange about every two and one-half minutes, or about 25 air changes per hour”
Also I don't believe the L1011 is fitted with ozone filters. Quote from Boeing "If this concentration of ozone were introduced into the cabin (refers to atmospheric ozone plumes encountered in flight), passengers and crew could experience any of the following symptoms: some chest pain, coughing, shortness of breath, fatigue, headaches, nasal congestion, and eye irritation. These are typical symptoms of high ozone exposure.
As Dr Syn points out SFB and MCO are well within the range of a 767. LAX is admittedly close to the edge with a full load. Not for a 330 though.
You may be on the right track Guv. I just can't avoid the impression that your love of the L1011 is blinding you to it's faults and to the advantages of other types.
For example..."Where people have fallen down with the L1011 in the past is largely due to the fact that it is such a good aircraft"
Please....how would those people have fared if it had been a bad aircraft?
