It is actually a lot more obvious than they make it out to be. Primary
for straight and level is altimeter and heading indicator. If you
think about it, that is the very definition of straight and level.
Straight means constant heading, level means constant altitude. The
primary for constant-airspeed straight-ahead climb is airspeed and
heading. Again, you can figure that from the definition
constant-airspeed and straight. The only exception is, attitude
indicator becomes primary anytime you make a large pitch or bank
change.

The supporting instruments can be a bit obscure. I treat every
instrument on the panel as a supporting instrument.

I'm studying for my written and having an awful time with the
questions dealing with primary/secondary instruments for
pitch/bank/power during various phases of flight. The distinctions
appear to be senseless hair splitting, and I'm getting them mostly
wrong in the practice tests. Some of this is due to my study
materials explaining which is the right answer, but not really *why*.
Is there any way to logically learn this in a way I have a prayer of
remembering, or do I just have to memorize the matrix?

Thanks,
Jeremy
