CPL Aerodynamics study plan
CPL Aerodynamics · Give each week a clear focus.
8 weeks · About 6 hours per week
Principles of Flight
Derive and explain the four forces in steady level flight, including how each changes with airspeed
Define lift coefficient, angle of attack, and dynamic pressure, and compute lift for a given wing area and speed
Sketch lift, drag, and power-required curves against airspeed and label the minimum-drag and minimum-power points
Compute induced drag and parasite drag at three airspeeds and identify the speed where total drag is lowest
Your checkpoint
A one-page handwritten formula sheet plus three fully worked lift and drag problems with units checked
Principles of Flight
Explain Bernoulli's principle and Newton's third law as complementary explanations of lift, and state the limits of each
Describe how camber, thickness, and aspect ratio change the lift curve slope and stall angle
Distinguish centre of pressure movement from aerodynamic centre and explain why the latter is used in analysis
Calculate the effect of density altitude on lift at fixed indicated airspeed
Your checkpoint
A 300-word written explanation of lift generation plus a labelled lift-curve-family sketch for three cambers
Aircraft Performance
Convert between indicated, calibrated, true, and equivalent airspeed using density ratio
Compute density altitude from pressure altitude and temperature and state its effect on takeoff and climb
Derive the relationship between power required, power available, and rate of climb
Solve five climb-gradient and rate-of-climb problems with correct unit conversions
Your checkpoint
A completed 10-question performance problem set scored at 80 percent or better with corrections annotated
Aircraft Performance & Stability and Control
Explain how weight, altitude, temperature, and wind each shift the takeoff and landing distance
Describe the forces and moments in a steady climb, glide, and turn, and identify the load factor in a level turn
Define static and dynamic stability and classify an aircraft as stable, neutral, or unstable in each axis
Compute load factor and stall speed increase for 30, 45, and 60 degrees of bank
Your checkpoint
A half-page summary table of load factor and stall-speed multiplier versus bank angle, verified by calculation
Stability and Control
Explain the contribution of the horizontal tail, wing sweep, and fuselage to longitudinal static stability
Describe how the centre of gravity position affects stick force, trim, and static margin
Distinguish dihedral effect, keel effect, and rudder authority in lateral-directional stability
Explain adverse yaw, aileron drag, and the role of differential and rudder-coupled ailerons
Your checkpoint
A labelled diagram set showing longitudinal, lateral, and directional stability contributors with a 150-word annotation for each
Stability and Control & Stall, Spin and High-Speed Aerodynamics
Explain the mechanism of flutter and divergence and the role of mass balance and stiffness
Distinguish static and dynamic imbalance and describe the control consequences of each
Describe the stall sequence from angle-of-attack increase through boundary-layer separation and buffet
Identify stall warning devices, wing-root stall design, and the effect of ice, frost, and contamination
Your checkpoint
A written stall-sequence narrative of 250 words plus a labelled diagram of the lift curve through the critical angle
Stall, Spin and High-Speed Aerodynamics
Explain the four phases of a spin and the control inputs required for recovery
Distinguish incipient, developed, and flat spins and state why flat spins resist recovery
Describe shock-wave formation, critical Mach number, and mach buffet
Explain sweepback, area rule, and supercritical aerofoils as compressibility fixes
List the factors that reduce stall margin and explain why load factor and bank angle raise stall speed
Your checkpoint
A two-page spin and high-speed aerodynamics summary with recovery checklist and compressibility definitions
Principles of Flight & Aircraft Performance & Stability and Control & Stall, Spin and High-Speed Aerodynamics
Complete two full-length timed practice papers under exam conditions
Re-teach the five weakest topics from memory without notes
Build a one-page error log categorising every missed question by domain
Verify recall of all key formulas and definitions against the week 1 formula sheet
Your checkpoint
Two scored practice papers with an error log showing every domain at or above 75 percent
Milestones
Week 2: Score at least 80 percent on a closed-book quiz covering lift, drag, and the four forces, and reproduce the lift formula without notes
Week 4: Score at least 75 percent on a mixed performance and stability quiz, and correctly compute load factor and stall-speed increase for all three bank angles
Week 6: Explain stall sequence and stability axes aloud in under five minutes with no notes, and score at least 75 percent on a stability quiz
Week 8: Average at least 75 percent across both full practice papers with no single domain below 70 percent
