Harry Arnold, chief engineer with Boeing's commercial airplane unit, said the company is "very actively" mulling two new variants of the 747 transport. The variants would require relatively modest changes, such as a longer fuselage or bigger fuel tanks, the newspaper said. Arnold did not say how much the two variants would cost. But people familiar with Boeing's internal studies said development costs would be about $500 million for the two planes in addition to about $500 million for safety testing and government approval, according to the newspaper. Boeing's decision to go ahead with the project would signal the company's determination to protect the 747 as the world's premier long-range commercial transport, the Journal said. -------------------------------------------------- --- DB 1.39/004487 * Origin: Volunteer BBS (423) 694-0791 V34+/VFC (1:218/1001.1) --------------- FIDO MESSAGE AREA==> TOPIC: 196 AVIATION Ref: EDF00011 Date: 09/11/97 From: ELVIS HARGROVE Time: 02:09am \/To: RAY HARKNESS (Read 0 times) Subj: My Sis -> Have you any knowledge of the above problems ? -=RH=- Yeah, Ray. JP-4 and Jet-A have the same sort of problems with the Diesel-bugs. This "Gunk" grows in the tank and renders the fuel useless. And the paraffin content of motor fuel Diesel is deadly if the filters are not appropriate. We burnt a lot of Mexican Diesel back during the fuel crisis and the GM engines HATED the paraffin! I agree that the Aviation fuel will have to be carefully controlled. ^..^ --- FidoPCB v1.5 beta-'j' * Origin: BOO!

A very likely reason for loss of cabin pressurization would be damage to the aircraft. If the aircraft were damaged, I would think that a high speed descent would be inadvisable. Since I don't have an ATP or multi engine rating, I have even less idea than a Concorde pilot as to what the manuals advise regarding maximum speeds with a damaged aircraft, but I would hazard a guess that the lower the speed, the better (safer). .. --- * SLMR 2.1a * - A waist is a terrible thing to mind. --- WILDMAIL!/WC v4.12 * Origin: The Looking Glass * Greer, SC * (864) 848-1961 * (1:3639/2.0) --------------- FIDO MESSAGE AREA==> TOPIC: 196 AVIATION Ref: EDM00002 Date: 09/15/97 From: CHARLES MIELKE Time: 06:56pm \/To: JIM SANDERS (Read 0 times) Subj: Re: news-673 JS> In a message dated 09-09-97 you wrote ...

Ray, I've used Diesel engine-powered machinery for many years and can comment a bit: Diesel fuel is organic, and it WILL grow "stuff" as you mention. I've not seen it to be a big problem, and I've had a lot of machines that have sat for extended periods. I'd bet on a Diesel starting with 3-year-old fuel in the tank, as opposed to a gas engine.:-) The supplier does provide a "winter mix" of Diesel fuel for operations below say 10 or 20 degrees F. It shouldn't be a problem with Av-Diesel to have different mixes or even simply run those Av-Diesel engines on Jet fuel. The latter isn't far off of automotive Diesel fuel anyway. <> --- FLAME v1.1 * Origin: Telnet toltbbs.com or call 313-854-6001, Boardwatch #55 (1:234/2) --------------- FIDO MESSAGE AREA==> TOPIC: 196 AVIATION Ref: EDM00004 Date: 09/10/97 From: JACK KINNEY Time: 07:55am \/To: HAL HANIG (Read 0 times) Subj: SPRINKLERS Hal refering to the use of fire sprinklers in a cargo A/C HH>Seems to me that dealing with a weight imbalance would be much more HH>preferable HH>than the alternative.
