Hi Martin,
I think this has been alluded to before, a few months back. See Europa
newsgroup exchanges re:'the step'.
Some say it is an illusion, others that it exists and has been documented !
FWIW, my guess is that it's illusiory.
I don't believe that ANY aircraft breaks the laws of aerodynamics, so if it
is a real phenomena, it'll be described
somewhere in the standard literature. Ask a boffin !!

Hi Folks,
One thing I noticed when I fly is if I level off at - say - 3,500 ft let
the speed build, throttle back to say 5,000 rpm I get around 115 kt
indicated. If I climb to 3,600 ft first then gently point the nose down to
bring me back down to 3,500 ft and let the airspeed gets up to around 125 kt
indicated, throttle back to 5,000 rpm the airplane settles back to 120 kt
indicated (where it stays). Don't know if its some weird aerodynamic thing
but it seems by pushing it over its normal cruise speed first then letting
it settle back to its own cruise speed, you get a few knots more than if you
were to let it make its own way up.
I haven't taken any scientific measurements just an observation of the
ASI.
Anyone else found this? Any ideas?
