If you do some math and interpolate the F-14B with its charts, V-n, Turn, SEP , the clean Sea Level turn rate probably is a few notches under 20. Say mid 19's.
The problem is the F-16 manual is a HAF manual for GREEK aircraft, it even says for Peace Xenia 2&3 aircraft. The weight charts 20,200-20,000-21,200lbs seem to be strictly for the Greek aircraft, For instance the Weight and Equipment pages that list those weights also lists the IRIST missile, the 600 gallon fuel tanks and their pylons, neither of which American Block 50 or 52 Vipers use. In addition, if you read into the manual, READ THE ENTIRE THING!, it lists for example a maximum allowable take off gross weight of 44,900lbs on pages A2-3 and on page C2-3. Also on page C1-3 totals to 43,229lbs weight in that problem. While the American Block 50 and 52 has a maximum take off gross weight of 42,300lbs. So something is not right here.
Then on pages A8-4 and B8-4 and C8-4 for the Acceleration examples beginning with GW of 20,000lbs, well by logic the earlier 20,200lbs, 20,000lbs, 21,200lbs Weight and Equipment pages would not match those Acceleration charts because the jet would be out of fuel or at negative fuel weights and that is impossible.
Most importantly, on page B1-3 it lists another weight, The Block 50 Start Engine Weight lists "Operating Empty Weight" of 19,261lbs and says that this figure is what is used in subsequent problems to eliminate "reworking".
So if you take that 19,261lbs number in the flight manual, and guessing that is its real weight. Use the 22,000lbs sea level max AB chart, and then take 22,000lbs -19,261 is 2,739. or about 38% internal fuel. To get 50% add about 840lbs and turn rate for sea level goes down from 21.7 to about 20.8. And that 20.8 is over 1 degree more than the F-14's max rate. So yeah in real life, in a two circle the F-16 (if it actually is not the Greek one) will out rate the F-14 by a large margin.
But you really need a non HAF manual, because the Greek one is simply full of too many contradictions. .
