Meanwhile, keep watching for shortage reports, because we should start seeing some sneak in this week, if our doom-o-meter is calibrated correctly.

nth as a science teacher i have to disagree with you. The biggest problem is resistance. Simply put water is five times as dense as air. Therefore the resistance is much greater. Water is also noncompressable which means it has to be moved out of the way. Momentum is another problem. If you have a train and aboat that weight equilvalent amounts and get each up to 20 mph and turn the engines off i am willing to bet the train will go much further. Try walking in a pool and walking on dry ground. The water "pushes back" more than the air.


Hrm... I am not a mechanical engineer nor a physics expert, so I am not going to argue with you on why water barge is more efficient. I think it has something to do with water able to support weight.

Anyways, the facts are that barge are more efficient. Don't trust my words as I know jack crap about this. I just based it on other experts.

I got that info from this article:

I google to double check and found this:

Thanks, Airline Pilot, for keeping track of this. I keep checking back, just to keep updated. I have a few relatives who depend on air travel for their jobs, and I've warned them about peak oil, so I'm trying to keep an eye on the situation for them.

Does anybody have any info on how the 1970s oil shocks played out in the airline industry? Just to get an idea of the possibilities.

Perhaps our science teacher or others espousing the efficiency of airtravel could let us know what energy is expended lifting mass 35,000 feet? Or accelerating rapidly to 600mph?

And don't forget that for millennia people have been traveling by boat using wind power (and of course good ol' slave power when the breeze dies down Shocked ).

This is interesting to me, as my husband works for a company that supplies aircraft with an essential part. At different conferences he's been to this year, the big boys are cranking up production on really huge aircraft, like Airbus's big ones that landed in the US last month. Boeing, too. This will all be very interesting!

This last week national average for jet fuel is up 5 cents from 2.03 to 2.08. Every penny is huge in terms of cost to airlines.

Avgas seems to be hovering around 4.16 for now.

Lets see at 5 cents per gallon that would be $574.45 per full fill up. Doesn't take long before those commuter airlines will be going broke or making major schedual reductions. Flying full already seems more important than customer service, I can't see this making things any better.

Airline pilot since you are inside the industry do airlines buy their fuel as a contract? Do they negotiate the price and get a wholesale discount? Or are airlines forced to buy the fuel like everyone else and are subject to daily price fluctuations?

We get fuel at contract for the hubs I believe, but when we fly to other destinations we have to buy it locally. Florida is really ugly on the fuel tax so we actually "tanker" fuel. We can frequently haul more than we need reducing what we have to buy away from the hubs. The problem with that is if your heavier due to the increased fuel load, it actually costs you slightly more fuel to do that. At the heavier weights it takes more fuel burned to go the same distance. Not a lot, but its measurable.

The airlines have been hedging fuel also but as of the last year or so its very limited. We actually lost a bunch of money last year due to the large price drop in crude. Sometimes its a tough game to play. Unfortunately they didnt ask me! Smile

Some good news! Jet fuel nat. avg. is back to 2.03 and Avgas remains stable at 4.16. I guess the demand numbers are fairly steady for these right now. I am guessing that might change though as it may become an issue for refineries prioritizing which fuels to make. Gasoline has a much bigger immediate impact economically and politically.

High Spreads For US Distillates Attract Imported Supplies

High differentials for middle distillates signify a shortage: a market screaming for imports. Record-high spreads for both jet fuel and ultra-low-sulfur diesel in the US reflect the aftereffects of the switch to ultra-low-sulfur diesel, which took place in the second half of last year. US reliance on jet fuel imports has deepened. That trend is likely to continue so long as US refiners are not producing enough middle distillate molecules due to various pressures.

Avgas now up to 4.18 and Jet fuel has jumped to 2.10 a gallon for the national averages.

That jet fuel jump is significant. Its up 7 cents since last week.

AirlinePilot, Is AVgas similar to kerosene? Just curious...

JP-8 is a kerosene derivative, so yes, I presume they're linked quite a bit.
