Jack,
It's a coincidence that I am also studying for the commercial
written test. I started the study last spring finishing all but one
chapter then got interrupted with a dive trip following with heavy
workload! We started the commercial flight training last August and
managed to get the two long x-country training trips combined with the
complex hours (our Cardinal has constant speed prop but no retractable
LG so we getting the 10 complex hours in a RG Cardinal). We also
finished the solo long country trips last Labor Day weekend.

The commerical maneuvers are fun to learn. Last week, our
instructor said we are close for the checkrides so we dusted off the
books to get ready for the written. I finished reviewing/studying the
Gelim CP FAA Knowledge Test in about 4 days and took the practice exam
at the end of the book for a score of 94% so I think I am close to
ready. I am going through another round of study before taking the
actual written test to allow for some test-anxiety-induced
mistakes ;-)

About the two online practice test sites, I had used the
exams4pilots.org site and found it quite useful especially for the
option to select the number of test questions. 10 questions at a time
is good for 5 minutes break during the day. I also find the answers to
be in agreement with Gleim's book. I had tried several online test
sites before and every so often, I would find the answers for few
questions contradicting with Gleim's book. I had just registered
for the second site and took all the exam questions of the first
chapter. There were two answers (out of something like 37) not in
agreement with the Gleim's book

A propeller rotating clockwise as seen from the rear, creates a
spiraling slipstream that tends to rotate the airplane to the
a) right around the vertical axis, and to the left around the
longitudinal axis.
b) left around the vertical axis, and to the left around the
longitudinal axis. (correct based on Gleim's book)
c) left around the vertical axis, and to the right around the
longitudinal axis. (correct based on mypilottests)

Since the prop and plane try to rotate in opposite directions (Newton)
c annot be correct.


Forst covering the upper surface of an airplane wing usually will
cause
a) the airplane to stall at an angle of attack that is higher than
normal.
b) drag factors so large that sufficient speed cannot be obtained for
takeoff. (correct based on mypilottests)
c) the airplane to stall at an angle of attack that is lower than
normal. (correct based on Gleim's book)


I think that b) need not be correct (how much frost?) but increasing
the roughness of the surface can promote flow separation c) Since
take off can occur in ground effect b) seems even more unlikely.

My 2c
