Aircraft Performance, Stability/Control, Compressibility

What are the factors in determining your takeoff critical field length for a certain runway? If after doing initial calculations you find the runway is too short, what might you be able to do as the pilot in command to be legal for takeoff? Compare and contrast the longitudinal stability of a conventional aircraft in two conditions: forward CG and aft CG? Discuss control forces and aircraft responses from trimmed condition if you pulled back on the stick and let it go. Compare and contrast a super critical wing with a laminar flow wing? Discuss modern aircraft that have utilized these wings. What are the enhancements and drawbacks?
