Hi,
I was just trying to calculate - in a "ballpark" way - the hourly fuel consumption for the 773; this is part of an exercise to try and determine the most economical aircraft for a long haul/low cost operation - purely for personal interest and not part of any commercial venture.
According to figures available to me, the 772 burns about 14,600lbs (or 6,500kgs) per hour and based on figures I've worked out so far, the 773 should have a fuel consumption of about 17-17,500lbs (or c.7,500kgs) per hour, to be close in efficiency to the 748I - which looks - according to projected figures - to be considerably more economical than the 380.
I appreciate (a) that it's a "how long is a piece of string" question to a certain extent - but let's just assume FL350 cruise and (b), there are issues of company confidentiality, but really all I'm looking for is a "feel" for how the 773 compares; as the largest twin engined aircraft available, I'd expect it to be among the most fuel efficient acft, per seat, available.
Many thanks for any help you can provide.
