Inaccurate performance data for BOB fighters in COD comparing to RL data

Crump wouldn't happen to fly blue by any chance would he?

He actully claims (or at least did) he plays NO PC games what so ever..

Which IMHO is funny, in an odd way, either way you look at it (true or false)

[Osprey]

In that case why would he hang around a gaming forum disagreeing with majority opinion without evidence......

S!

This fuel testing is done today also every day to ensure that no contaminants or similar enter the plane. Sure the methods are a bit better though. Leave out the smack talk etc. and this thread is very interesting.

Bingo!

That is one of the 'funny' thing I was referring too..

I am sure he considers it some sort of 'duty' on his part to set things right in the simmer world! Because god knows a guy with a pilot's license trumps anything said by a guy without a pilot's license! Some (most?) pilots are funny like that! Which reminds me of a little joke..

If your in a room full of people..

Question.. Do you know how to tell who are the pilots in the room?
Answer.. Easy, they are the ones that during any introduction point out they are pilots

Example

You: Hi my name is Dave what is your name?
Pilot: Hello my name is Eugene, I am a pilot!

The wristwatch. It's the wristwatch that's the giveaway. Every time.

Cool! I'ld better start mentioning it a bit more often. Did you know I've got a ..... Hang on! Do you need a current medical certificate??????

What was the storage life for the fuel,

Don't confuse the sweetened stock with the blended fuel you put in your tank. Blending does not occur until the gas is leaving the storage facility and heading for the pump to be sold or put into a vehicle to be used. Once it is blended, it is considered consumed.

All the 100LL stock is made one time per year. It is not blended though until it is sold to an airport. The Reid Vapor Pressure tolerances of aviation fuel are much more stringent than automotive fuel.

The Energy Information Administration says the switch between the two fuels happens twice a year, once in the fall (winter blend) and again in the spring (summer blend). Summer-blend gasoline is typically more expensive to produce than the winter blend, and it won’t affect vehicle performance or the durability of the engine and fuel system, according to the EPA.

You can get away with blending automotive fuel twice per year for the most part.

Airplane fuel does not work that way. My old Socata used to have vapor lock issues because I did not fly for months when I was away on business. The plane would sit with full tanks in the hanger. By the time I got to fly it, the conditions had changed from when it blended to maintain Reid VP and I would end up hitting the auxiliary fuel pump all the time to keep my fuel pressure up so the engine would not quit. Once that gas was out of my tanks, I did not have to use the aux pump except for start, takeoff, and landing.

For example, 100LL stock is refined only ONCE per year in the United States. The stock is then distributed to the holding yards. When it is dispensed to the airports, the final mix of that stock occurs and it becomes 100LL fuel. Just because the airport buys 15,000 gallons does not mean it will be sold and go into airplanes by the time the shelf life is over. That is why airport managers keep data on fuel sales!

That does not mean they mixed up a huge batches of 100 grade to be "disposed of" either. In many cases fuel can be converted back to stock and then again to a lower grade. It is still 100 grade that is consumed whether it comes back to the holding yard or not!

This is why the same reasoning that was used to "prove" the 100/150 grade extent of use was so flawed. First the strategic stocks must be maintained and once the fuel is mixed, it is "consumed". Nothing to do with it being blown out the exhaust pipe of an airplane.

And what exactly do intensive wartime operations of military aircraft have to do with what US civil aviation does with fuel blended and used for peacetime civilian operations? Socata's sitting in hangers for months? So What? For instance, the standard practice of the RAF was to fill the tanks of their fighters asap after landing to avoid vapour locks, condensation etc - there was no time for fuel to deteriorate through sitting around in a hanger for months waiting for something to happen. By Crumpp's reasoning the RAF mixed up small batches of 100 octane fuel then let it sit around, or tested it to see if it would work, instead of using as much as possible at a time when the country was facing full scale air assault!

Confusing peacetime civilian practice with military practice during wartime, and saying that the same constraints apply to the use of aviation fuel is just nonsense. It is just another red herring by someone who doesn't want to admit that he has no arguments left against FC using 100 octane fuel for all of its front line operations by Hurricanes, Spitfires and Defiants throughout the Battle of Britain.
