What is the difference between rate of roll and roll displacement?
I was studying Principles of Flight, I came across a sentence which is my question.
_ the aileron is known as a rate control since a given aileron angle of deflection determines a rate of roll, not a ...

Aircraft load factor and body normal acceleration
A load factor is defined as "the ratio of the lift of an aircraft to its weight", i.e., N = Lift/Weight.
Normal acceleration (nz) is defined as the component of the linear acceleration of an ...

Is this description of lift and drag coefficients correct?
In my course (Principles of Flight) written:
The effect of CLift is not linear. This means that Lift doubles for
double the lift coefficient.
And
The effect of CDrag is linear. This means that for ...

Does downwash increase or reduce lift generation?
I’m wondering about the impact of downwash on lift generation. I've read that, because downwash creates lift according to Newton's third law of motion, increases in downwash due to greater AoA (...
