I think that some people have stated that non operational flights were done on 100 octane and non operational flights on 87 octane. Postings have been made saying that in one month a squadrons did X operational flights and Y non operational flights.

We agree that this wouldn't have happened which is good

What would be worth it to do is change the fuel type when the units rotated out for rest and refit. They are not doing any operational flying under that status and unless they had an additional mission to gather data on the fuels use, there is no reason to continue to use 100 Octane. I am sure maintenance trend data over as many hours of flight time was required before the entire force converted but you don't need it from every squadron.

The difference between us is that when they moved for rest normally to a Group in the North they normally remained as Operational squadrons. Look at the OOB and compare then number of Operational and Non operational squadrons. A handfull are non operational. As I said Operational used 100 octane and non operational 87 Octane.

Crumpps steps to conversion.....

If I wanted to convert and it was not possible to convert the entire force, the first thing I would do is get as much 100 Octane gas to the airfields as I could before anyone converted. Then my conversion pool has a supply of gas.

The next thing I would do is convert as many squadrons as possible to be able to use 100 Octane. That timeline is going to be based on how fast the parts required can enter the system and reach the point of use. I would convert as many aircraft as possible without violating the required logistical ratio so my airplanes can continue to fly and I am not without airplanes due to maintenance awaiting parts. Now I have pool of capable aircraft.

As much as possible all of my operational squadrons using 100 Octane would be down in 11 Group in the thick of the action.

If logistics said I only had enough fuel for 16 squadrons by September then you can bet when a squadron rotated out for rest and refit, they would go back to 87 Octane and their replacement would come from that pool of converted units.

As logistics increased my usable fuel supply, I would add operational squadrons to other areas until the entire force was converted.

Your steps are basically the same as the RAF, The fuel had been issued by May 1940, the changes to the aircraft were very small, took about a day and the task was completed in May. The March paper listing the changes showed that the major conversion task was already included in new engines or in normal routine maintanence, all that was left was drilling a couple of holes so that side of the Logistics was covered, all that was left was delivering the fuel of which there was no shortage.

Now you seem to have dropped the pretence that 1940 was about operational testing which is good, now can you supply the 16 squadrons evidence?
