Help on Portfolio Question

(1/2) > >>

Atetos:
Hi,

I am working on my portfolio for TESC and came across a question on it that I am not incredibly familar with anymore.  I have been out of the Navy for almost 5 years now.  The question refers to the operation of a three element level control system.  That is all the objective states.  Can anyone give me a couple of refreshers on this Topic?  Thanks.

This Help????
