airbus,

simple-yes

correct-no!

In a steady state climb lift is actually reduced compared to S&L at the same speed. The vertical component of thrust puts the forces in equilibrium.
I find this very difficult to swallow.

There are airplanes out there that can actually have a nose down pitch in level flight and for that matter can climb with a nose down pitch. How do you explain that.

Also if you are cruising a jetliner the attitude is somewhere around 2.5 degrees up. When you add additional thrust the attitude increases in order to prevent the airspeed from increasing which increases lift and the altitude increases.

As for the vertical component of thrust, it doesn`t matter where the lift comes from it is still lift. By your argument one could say that a hovering helicopter is not producing lift.
