Wilton, wouldn't that be only measured at sea level? I would
think that as you go higher in altitude that one minute of arc
would get longer. Now mind I'm only thinking back to my school
days and that circle and pie wedge thing in beginning geometry.

BTW, a nautical mile (6080 feet) is also one minute of arc of
latitude - on
land, on water, on ice, in the air, wherever. A statute mile, of
course, is
5280 feet.
Because the definition of a "knot" is one nautical mile per hour,
it is not
necessary to repeat "mph" when speaking of knots.
