In the F3 Tornado, with full 1800L U/Wing tanks, the A/C is restricted to around half it's maximum g loading, however, this jumps up to around 3/4 of max once the tanks are empty, which is quite a considerable jump.
Errrrm we dont have 1800L u/wing tanks. Its either 1500L or 2250L, unless there is one I have never heard of..........
Agree with the reduction in g though
