This essay is to discourage the description of control "pressures" rather than control inputs and control surface deflections.  

The terminology is common parlance:

"In a turn the necessary additional lift is acquired by applying back pressure to the elevator control"

 

             - The Pilots Handbook of Aeronautical Knowledge FAA-H-8083-25

It is even used in an advisory circular on stall recovery no less than four times!

"Every aircraft may require a different amount of forward pressure or relaxation of back pressure to regain lift"

             - AC-61-67C Stall and Spin Awareness.

Interestingly an article from Boeing chooses to phrase it like this:

"To recover from the stall, angle of attack must be reduced below the stalling angle. Nose-down pitch control must be applied and maintained until the wings are unstalled"

                  - AERO Magazine Issue 03 -July 1998

                               

Remember, control pressures are a function of airspeed and trim condition, not aircraft attitude. 

Using the terminology of "pressures" masks the real goal of deflecting control surfaces as appropriate to control pitch, back and yaw.  It may convey a dangerous misconception for aircraft recovery.
