Whatever cruise rate they were using,
The reason I gave the data was your messages, #172 about US bomber (and fighter) speeds and #237 about German bomber speeds, they were not F4F economic cruise speeds, I was providing the correct information. I receive an editorial long on how you are right on topics I did not mention, now go away. I work on the principle the more editorial, the less accuracy.
As for the bombers diving, London to Dover is around 70 miles, the bombers are 3 miles up, work out the slope assuming the bombers are at zero feet at the coast, or the lesser slope assuming they want to stay above light AA range, then work out the actual speed boost.
Somehow there seems to now be a myth developing that Wildcats were slower than any of these bombers, which is ridiculous.
I suggest you stop developing it and address the problems you are ignoring.
Everyone else is just kind of trying to pretend that Wildcats can't fly fast or that they suffer problems that a 109s does not.
Actually I read it as you are pretending that is what other people are saying.
For example, all of these are British tests by the way.
Martlet I "most economical" 167-175 mph, maximum weak mixture 257 mph. Range 870 miles. (no aux or loiter time indicated)
Martlet II "most economical" 170 mph, maximum weak mixture 260 mph. Range 850 miles (no aux or loiter time indicated)
Wildcat II "most economical" 213 mph, maximum weak mixture 246 mph, loiter 181 mph. Range 795 miles. Loiter 3.95 hours.
Wildcat IV "most economical" speed 213 mph. Maximum weak mixture 238 mph. Loiter 181 mph. Range 695 +452 aux tanks, 3.5 +2.3 hours loiter.
Wildcat V "most economical" speed 218 mph. Maximum weak mixture 262 mph. Loiter 185. Range not given.
The ranges the British tests give are economic cruise, not maximum weak mixture cruise. Unlike the data I posted which made clear the speeds involved. Next note the Wildcat II card of 6 February 1944 supersedes the Martlet II card of 22 August 1941, but they are very different aircraft. The Martlet I card is 22 August 1941, the IV is 6 February 1944, the V is 11 November 1944.
The USN says the F4F-3 had an endurance of 1 hour at maximum speed at 19,000 feet, that is around 323 miles, the Bf109E-3 economic cruise was 410 miles. No one is disputing the F4F had a greater range. The advantage decreases with speed, partly as 300 mph is around 91% of the F4F-3 top speed, it is 86% of the Bf109E, and that small percentage does make a difference
The F4F-3 is quoted as 940 miles at 150 mph at 2,500 feet using 144 gallons of fuel. The F4F-4 drops that to 830 miles at 161 mph at 5,000 feet. The rise in fuel consumption with speed, F4F-4 range/speed curve at 5,000 feet, 144 gallons of fuel.
161 mph, 830 miles
200 mph, 715 miles
220 mph, 625 miles
240 mph, 500 miles
285 mph, 280 miles
See the attached, condition 2 is fighter using normal power, condition 4 is fighter, normal power, 2x58 gallon external fuel tanks. The graph shows the trade off between speed, altitude and longest range.
The USN says at 195 mph the F4F-3 had a range of 930 miles at 19,000 feet, (4.8 hours times 0.6 times 323 mph) at 240 mph 800 miles (3.3 hours times 0.75 times 323 mph), at 323 mph 323 miles (1 hour times 323 mph), yet gives the maximum range as 940 miles at 150 mph at 2,500 feet. Somehow an extra 110 miles range advantage over the F4F-4 at 150-160 mph becomes an extra 235 miles at 200 mph and 250 more miles at 250 mph. Shall we say there is an issue here. Using the F4F-4 curve the F4F-3 would have twice the range of the Bf109E-3 at 200 mph.
The RAF reports the Spitfire I was good for 415 miles at 304 mph, to get the official 575 miles range cruise was 180 to 190 mph. The Hurricane I range around 275 mph was 340 miles, at 180 mph 600 miles.
Assume the B109E-3 range degrades in the same way as the Spitfire, given similar top speeds, 410 miles at 200 mph becomes 295 miles at 300 mph. The F4F-4 range advantage drops from 75% more to actually less. The F4F-3 range advantage drops from around twice as much to still better, given it could do 323 miles at 323 mph if the endurance chart is accurate and remembering it starts with a range advantage over the F4F-4.
Put it another way, flying beside a Do17Z the F4F-4 was good for 760 miles, beside a Ju88A-1 550 miles. At 180 mph the F4F-4 could out range the Hurricane by 200 miles, at 275 mph it had about the same range.
The F4F-4 rate of climb, normal power is 2,200 feet per minute at sea level, down to 2,050 feet per minute at 4,000 feet, holds that to 11,500 feet then it steadily degrades, 1,600 feet per minute at 16,000 feet, 1,200 feet per minute at 20,000 feet, 800 feet per minute at 25,000 feet. It costs the F4F more fuel than the Bf109E to climb given the longer duration, add that the F4F-3 took off at around 7,556 pounds, the Bf109E-3 was 5,875 pounds, raising a ton 5 miles costs, the F4F is almost 30% heavier.
Unless you can show that the stated range limitation for the Bf 109 and Bf 110 were done at 300 mph, then I don't think there is any point here.
I know you do not see despite so many people trying to explain. And the editorials show you are uninterested. After all I posted the Bf109 and Bf110 ranges noting they were economic cruise now apparently the requirement is 300 mph, an estimate is given above. Now remember, replying your idea is better requires some evidence, not an assertion. Otherwise I do not see any point here. I am sure someone with better knowledge of the DB601 could provide a more accurate idea of fuel consumption at different power levels. I do note Eric Brown quotes the Bf109G-6 range as 350 miles at 330 mph at 19,000 feet, implying the Bf109E range figures are at fast cruise.
On another point fundamentally for most of the Pacific air war the chances of interception away from a Japanese base were small so allied aircraft cruised at optimum for range and in loose formations.
