“300
mph. Vne for the 320 is 270 mph.”
Now – let’s see. What have I got here.
Paper –yep. Pencil – Yep.
1
multiplied by 5280 – yeah - then divided by 6080 - yeah – now
that’s – lessee – 0.8684
Now,
lessee, if I multiply 300 mph by 0.8684 I get – let’s see –
um – 260.52. Yeah – now I think that’s KNOTS.
Now
if I use the same pencil and paper, and stick 270 mph in the same position as
300 mph, I get – er – lessee, 234.46 and now I know that’s
KNOTS –
Wow
– that’s what my Lancair ASI says. Phew!
Ciao
for now.

Posted for rwolf99@aol.com:
I won't mention names here but a recent posting caused me great concern.
Regarding pushing your 320 to the limit -- I'm certain that exceeding 300
mph
is a thrill, but it is also pushing it *beyond* the limit. Vne for the
320 is
270 mph. That limit is chosen for a reason. Might be
flutter, might be
overloading by a gust, might be something else entirely. We know
where the
limit comes from for certified airplanes but not for experimentals.
It does not matter how well the systems are maintained. Vne is
Vne and
should never be exceeded.
If you're going to continue doing this, please do it without me or any of
my
friends on board, and please don't do it over my house. Oh, and
please be
uninsured so that I don't have to pick up part of the tab if your airplane
comes apart.
