F-14 on the History Channel's "Modern Marvels"

Actually, the wings were programmed for best cruise which targets least drag
for current speed. A level acceleration closely hits those airspeed check
points ... there's no advantage to sweeping the wings on a level accel
because induced drag and trim drag will initially (at the starting speed of
the accel) increase significantly with the wing sweep. Unloaded (and
following optimum flight path for max PsubS) there's an advantage to
sweeping the wings. There are times when an unload is practical. There are
others when it is not.

Pete's right. airsource off helps.

JD- Actually if you were to compare the F14 with the F110 engines to the
F15, the acceleration at SL would be even from M0.5 to M0.9. This is
with the F14 wings set to "Auto". If the F14 wings were set to manual
and the wings set fully aft, the F14 would be a lot faster. BRBR

'A lot'??-manual aft, airsource off type acceleration?
