About the book entitled: Test Pilot, 1001 things you thought you knew about aviation

Good day all,

I was at Borders the other day and read a few trivia questions out of
the subject book's "piloting" chapter. The author is Barry Schiff.

Have any of you have read it? Even though the questions were
challenging and thought-provoking (they had to kick me out of the
store when I wouldn't leave), I did find two or three answers that I
thought, IMHO, were incorrect. If I recall, they were with reference
to glide angle changing with respect to weight with no pilot input.
Did anyone find the same?

Best regards,
Alex
