Default I passed the checkride, now need a good GPS and passenger headset

Don't forget, Dud, that 50% of all CFIs are below average. ((:-))

I'm sorry you have such a low opinion of flight instructors.


Uhm, Vince is alluding to the surprise of President Roosevelt (I think)
about the fact that 50 percent of the US population had (and have) a
below-average intelligence.


Right. I don't know about FDR, but the statement that "50% of all
_______ are below average" is a favorite of math and statistics
teachers.

This, as Vince's statement, is inherent in the definition of "average" -
well, not exactly, I know, but kind of, assuming an equal distribution around the average.


Most statistics books I've seen say the median and the mode are, like
the arithmetic mean, "averages." But you got the right idea; half of
all cfi's are below the arithmetic mean only if the population is
normally distributed. Quite unlikely.
