Kramer,
It took me 5 seconds to find this:
how to control an aircraft
What is stated there, of course, is dead right, regardless of what your theoretical definition of "effect" may be.
You would be well advised to also have a read of Handling The Big Jets, in particular the section on takeoff and landing. One bit says:
"a high sink rate must be countered by increased incidence coincidentally protected by an increase in thrust to counter the extra drag."
And a quote from "Fly The Wing":
It is dangerous to believe that rate of climb or descent is strictly a function of power, that an airplane goes up or down as a function of applying power of pulling it off. A very basic understanding of aerodynamics proves that a wing in flight climbs or descends as a result of angle of attack and lift variations at various angles of attack. Power or thrust merely pushes or pulls the plane through the air fast enough for the wing to become aerodynamic, to furnish lift. From then on, climb and descent are functions of pitch attitude (lift coefficient) and are controlled by the elevators. The power controls the speed-period!. This is the whole essence of flight, particularly jet flight"
Practical and safe aviation verses blinkered theory...
