International Standard Atmosphere (ISA) PropertiesPrimary and Secondary Flight Control SurfacesAirfoil Geometry Nomenclature (NACA 4-digit series)Pitot-Static Tube Principle for Airspeed

🔥 Most Predictable Exam Questions (1)

Guaranteed Every Year 8 Marks Module 1: Flight Fundamentals

Q1. Explain the 4 primary forces acting on an aircraft in steady level unaccelerated flight (Lift, Drag, Thrust, Weight) and derive the equilibrium equations.

Key Points: Draw free body diagram. In steady level flight: Thrust = Drag (T = D) and Lift = Weight (L = W = 0.5 * rho * V^2 * S * C_L). Explain angle of attack alpha and stall condition.
