Subject: [LML] Vne for = 300=20 series Lancairs

320/360/390 drivers in the 320/360 fuselage:

235 KIAS =3D Vne, assuming that a good static port is used, then = also=20 assume KCAS =3D KEAS =3D KIAS

Here are some interesting data points:

Assume indicated altitude =3D Palt =3D Dalt and Baro =3D = 29.92

at 17,000 ft. and -18C, 180 KIAS =3D 235 KTAS

at 10,000 ft. and -5C, 201 KIAS =3D 234 KTAS

at 5,000 ft. and 5C, 217 KIAS =3D 234 KTAS

As a practice (and not based on any logical reasoning) I normally = descend=20 from most altitudes at a comfortable 180 KIAS. I = haven't been=20 over 11,000 feet since the last Redmond Labor Day fly in (several = years ago)=20 that would have required high flight over the smoke and mountains. = I=20 don't remember descent air speeds from those higher altitudes.

BTW, my NA 170 HP engine will not quite get me to=20 the destructive Vne in cruise. When I raced cross country = (2000 to=20 4000 ft), I have achieved 205 KIAS. On a hot day that might be 217 = KTAS.

I feel so much better now.
