“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!
