A) Airfoil shape and angle of attack

B) Wing span and aircraft weight

C) Engine thrust and fuel consumption

D) Air temperature and humidity

A: A) Airfoil shape and angle of attack

Explanation: Lift is mainly generated by the airfoil's shape (camber) and the angle of attack—the angle between the chord line of the wing and the relative airflow. These factors influence the pressure difference above and below the wing, creating lift. While wing span affects lift capacity, the shape and orientation are fundamental to lift generation at a given speed.

Question 2: Aircraft Structures

Q: What is the primary purpose of stiffeners in aircraft fuselage panels?

Explanation: Stiffeners are structural reinforcements added to fuselage panels to enhance their strength and prevent buckling under load. They ensure the fuselage maintains its shape under aerodynamic pressures and loading conditions, contributing to overall safety and durability.

Question 3: Propulsion Systems

Q: The main advantage of turbofan engines over turbojet engines is:

A) Higher speed capability

B) Better fuel efficiency and quieter operation

C) Simpler maintenance procedures

D) Ability to operate at higher altitudes

A: B) Better fuel efficiency and quieter operation

Explanation: Turbofan engines incorporate a large bypass ratio, which improves fuel efficiency and reduces noise levels compared to turbojets.
