My, my. Aren't we a bunch of techno-illiterates?

1 nm = 6076 ft 1 kt = 6076 ft/min

Err, no!

1kt is 6076 feet per hour or (for all practical purposes) 100 ft/min.

Ahhh - God bless the metric system!
Wait wait - let me get into my Nomex suit first! ;-)

Bwa ha ha!!! Uli, you demonic, bomb-throwing, scum. May your next 1000K flight
be at a very slow rate of knots.

Bob - feeling my humor oats this AM - W.

P.S. Clearly both the Aera 660 and ifly720 are devil-instruments, unsuited for
the soaring world.

In the UK soaring community we use a much more eclectic mix of units than
is common in the USA.

Glider instruments use ICAO units (knots for airspeed and climb rate,
feet for height, Centigrade temperatures, millibars for atmospheric
pressure and altimeter settings and bars for other pressures, e.g. tyre).

OTOH tasks are metric (kilometers and meters for distance, km/h for
speed).

Everybody, even now XC pilots, seem to do this without undue mental
strain.

European gliding is entirely metric. I've flown gliders at Wiener Nuestadt
(Austria) and the Wasserkuppe (Germany) without numeric confusion because
the ASI is the right way up and speed bar markings are the same colours,
though I do tend to misunderstand climb rates in m/s - 1m/s approximates
2kts.
