There is thing called the Paris Convention of 1919. It is what gives British Aircraft the authority to fly in other countries, including the USA.

What it says in summary, we will all do things the same way regarding airplanes and meet the same standards.

Osprey,

It is a fact the January 1942 Pilots Operating Notes for the Spitfire Mk Ia stating 100 Octane is for ALL OPERATIONAL UNITS. That fact is a very damning piece of evidence for any argument all operational units converted at any date before January 1940.

It is a huge "fly in the oinment" to the crowd claiming Fighter Command converted in the Spring 1940. People in this thread have bought into a position based on logistical documentation and not on operational documentation.

The Operating Notes are operational documentation and the logistical documentation showing the fuel supply at the airfields confirms Morgan and Shacklady's research of around 16 squadrons sometime in September 1940.

The argument the document combines fuel at the airfields from 1938 until June 1940 does not hold up to scrutiney. Why?

The process for manufacturing 100 Octane gasoline cheaply and in quantity only existed for one year in 1938.

The first full-scale commercial catalytic cracker for the selective conversion of crude petroleum to gasoline went on stream at the Marcus Hook Refinery in 1937.

Before catalytic cracking, making 100 Octane fuel was possible only in small quantities and it was very expensive to manufacture.

In 1936 the United States decided to adopt 100 Octane. The Aeronautics Branch of the Department of Commerce, NACA, and Department of Defense laid out a ten year plan to convert all aviation to 100 Octane fuels. The first to convert would be the USAAF and their experience would be used to convert all Civil Aviation. Before any of that could begin, the first priority was finding a way to make 100 Octane cheaply and in quantity. That was not a possibility until 1937.

I highly doubt the Air Ministry had 100 Octane fuels in any substantial quantity in 1938.
