Gary Lager has answered the question very very well indeed.
Gary, stand by for incoming flak from those who would have you believe that jet engine thrust declines with speed. Indeed it does, until about M0.5, whereafter ram recovery steadily restores the thrust to approximate static speed values in the vicinity of M0.75. After that, thrust in
SOME engines will exceed static thrust. The Net result is that as the Power required curve bends upwards, so too, does the Power available, as the now increasing (recovering) thrust is increasing commensurate with the speed increase, yielding a Power Available curve also curving upwards, approximately paralleling the Power Available curve over a fairly significant speed range (30 to 40 knots). It's not unusual to see a best rate of climb speed in excess of the final Maximum Range Cruise speed.
It's absolutely true that ram recovery is not as great for modern high bypass engines as opposed to their earlier ancestors, but those internal compressor/turbine cores driving the ruddy great fans just loooove that ram recovery.
I've had one (alleged) expert try to convince me that ram recovery in high bypass engines was insignificant, with supporting data which proved that the modern jet couldn't hope to achieve much more than 300 knots in level flight
