Does anyone know the address for the publishers of De Principia Mathematica ?
A simple revision would, I am sure, have it selling like hot cakes among you mathematically inclined aviators.
If Sir Isaac Newton had had the foresight to express g in useful units, rather than this 32.2 ft/sec/sec; 9.81 metres/sec/sec nonsense, I am sure you would all go out right now and grab your copy of his book. And Mr Kermode would have a lot less to talk about on the subject of consistent units of measurement.
Ike should have used nautical miles/hour/hour, or Knots/hour. Then g is the easily remembered number 68600 (roughly). Just rolls off you tongue, doesn't it ?
If we bung that in the Genghis/gaga example, using PROPER measures of speed and distance, we get
tan(angle of bank) = TAS squared / (68600 * turn radius)
= (230 x 230)/(68600 x 1.65). That is, use knots and nm directly.
AOB = 25 degrees.
So everyone, repeat after me
"THE FLYING PERSONS GRAVITATIONAL CONSTANT IS 68,600 kt/hr (to about 3 places)"
And NO, I don't want to be nominated as the supplier of this week's most useless bit of information.
HAPPY NEW YEAR TO ALL
