It is the process of moving from set of conditions to another. Dynamic verses Static. This is the concept that is being pointed out. |
Yes，in 45 degree dive, aircrafts are always unbalanced , aircrafts are always increasing speed, always accelerating.
This is a dynamics process, in this process, if my la7 throttle is 100% while your la7 throttle is 60%, I can always outdive you when moving to the equilibrium point which impossible for real flight.
Why? My la7 100% engine produce more thrust than your 60% engine in 45 degree dive, so I have more excess thrust during the whole dive, finally, I can get better dive acceleration than you. understand?
Even if you turn off fuselage damage in difficulty setting, both of us could achieved "equilibrium" speed:
I, with throttle 100%, equilibrium speed is 1000km/h
You, with throttle 60%, equilibrium speed is 950km/h
I can still pull away from you because my engine give me more thrust. Look this picture, when both of us reach equilibrium point, my air drag force is higher than you, this is to say, my speed is bigger than yours.

Now , do you still believe that engine could not produce excess thrust during high speed>Vmax dive?
