Which of the following is incorrect?

(a) Uncambered wing lift curve is not same as that of the Cambered

(b) Stick free and stick fixed are same

(c) Lift is not always same as weight

(d) Thrust required is not always same power

This question was posed to me during an interview.

My doubt is from Stick-Free Stability topic in chapter Stability, Control, and Handling Qualities of Aircraft Design

Best answer
Correct choice is (b) Stick free and stick fixed are same

Easiest explanation: Wing lift curve is different for uncambered wing and Cambered wing. Stick free and stick fixed phenomena are not same. Lift is not always same as weight. During cruise lift and Weight will be equal. Thrust required is calculated based on drag of the system.
