I have see what they are doing, and it makes allot of sense - that's why I
brought it up.

>> Hello Greg,

>> The notes at the bottom give the rated min. temperatures for the fuel.
>>
>> Depends where it is and at what time of year but your 80,000 ft high

>> as
>> I think you implied. The ozonosphere shows a positive lapse rate, i.e
>> increasing temp with altitude.

>> Since the troposhere is where the weather is, i.e where most of the water

>> Making jets fly higher into the stratosphere might be the solution to

>> AVIATION FUELS
>> NATO CODE
>>
>> F-18
>> is an aviation gasoline (low lead) in limited use by certain NATO
>> nations.
>> Also known as AVGAS 100LL.
>> F-34
>> is a military kerosene type aviation turbine fuel with Fuel System Icing
>> Inhibitor (FSII) (NOTE 1) used by land based military gas turbine engined
>> aircraft in all NATO countries. (NOTE 2) Also known as JP-8 or
>> AVTUR/FSII.
>> JET A-1 or AVTUR + Additives (NOTE 3) = JP-8 or AVTUR/FSII.
>> F-35
>> is a military kerosene type aviation turbine fuel equivalent to that used
>> by
>> most civil operators of gas turbine engined aircraft. Also known as JET
>> A-1
>> or AVTUR.
>> JET A-1 or AVTUR; therefore F-34 = F-35 + Additives.
>> F-40
>> is a military wide cut type aviation turbine fuel with FSII used by land
>> based military gas turbine engined aircraft (NOTE 2). Also known as JP-4
>> or
>> AVTAG/FSII. Within NATO it is an emergency substitute for F-34/F-35.
>> F-44
>> is a military high flash point kerosene type aviation turbine fuel with
>> FSII
>> used by ship borne military gas turbine engine aircraft in most NATO
>> countries. Also known as JP-5 or AVCAT/FSII JET A and JET B (See NOTES 4
>> and
>> 5)
>>
>>
>>
>> NOTES:
>>
>>
>> FSII NATO Code S-1745. Additive to aviation turbine fuels as system icing
>> inhibitor.
>> Until 1986, F-40 was used by land based gas turbine engined aircraft in
>> all
>> NATO countries except France and the United Kingdom which had converted
>> to
>> F-34 some 15 years earlier. Following a decision by NATO Defence
>> Ministers
>> all nations except Turkey switched from F-40 to F-34. The conversion
>> (known
>> as Stage 1 of the Single Fuel Concept) was completed in 1988. Turkey
>> completed its conversion from F-40 to F-34 in 1996.
>> The term "additives" used in this Aide Memoire can include FSII corrosion
>> inhibitor/lubricity improver additive and static-dissipator additive
>> (SDA).
>> JET A is a civil grade of kerosene type aviation turbine fuel only
>> supplied
>> for operations in the United States. It has a freezing point of -40oC max
>> which differs from JET A-1 (-47oC).
>> JET B is a civil grade of wide cut type aviation turbine fuel which has a
>> different freezing point (-50oC) from F-40 (-58oC) and does not normally
>> contain FSII.
>> For further details about these fuels, see Annex C to STANAG 1135.
