NCAA PPL Principles of Flight study plan

NCAA PPL Principles of Flight · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Principles of Flight

  • Define the four forces of flight and state how each changes across the takeoff, climb, cruise, descent, and landing phases

  • Explain how lift is generated using both the pressure-distribution and Newtonian (downwash) descriptions, and note where each description is incomplete

  • Draw and label the four force vectors for steady straight-and-level flight, a constant-airspeed climb, and a constant-airspeed descent

  • Compute the lift equation for two sample aircraft states, changing one variable at a time, and describe the resulting effect on stall speed

Your checkpoint

A one-page force diagram set (level, climb, descent) plus a worked lift-equation table showing how stall speed shifts with a 10% and 20% weight increase

Week 2

Principles of Flight

  • Describe the four relative-wind and chord relationships that define angle of attack, and distinguish angle of attack from pitch attitude

  • Explain the lift curve: linear region, critical angle of attack, and post-stall behavior, and state why the stall is an angle-of-attack event rather than an airspeed event

  • Identify the factors that shift the lift curve (flaps, ice, Reynolds number) and predict the direction of each shift

  • Relate load factor to stall speed using the square-root relationship and calculate stall speed at 2g and 3g

Your checkpoint

A hand-plotted lift coefficient versus angle-of-attack curve with annotated critical angle, plus a load-factor stall-speed table for 1.0, 1.5, 2.0, and 3.0 g

Week 3

Principles of Flight

  • Explain induced drag, its origin in wingtip vortices, and why it varies inversely with airspeed squared while parasite drag varies directly

  • Construct and interpret the total drag curve, marking the minimum-drag speed and the region of backside (reverse command) flight

  • Describe the four factors affecting parasite drag and the effect of weight, altitude, and bank angle on the drag curve

  • Explain why the best glide speed changes with weight but not with altitude, and identify the practical consequence for engine-out glide range

Your checkpoint

A labeled total-drag curve with parasite, induced, and total components plotted, annotated with best-glide speed, minimum-drag speed, and a written explanation of backside flight

Week 4

Principles of Flight

  • Explain thrust and power required versus available across the airspeed range and locate the speeds for maximum endurance and maximum range

  • Describe how propeller efficiency, pitch, and slip vary with airspeed and power setting

  • Explain the four left-turning tendencies and state the phase of flight in which each is most significant

  • Describe stability: static versus dynamic, and longitudinal, lateral, and directional stability with the design features that provide each

Your checkpoint

A power-required versus power-available graph with endurance and range speeds marked, plus a table matching each left-turning tendency to its cause and most affected flight phase

Week 5

Principles of Flight

  • Explain how flaps, slats, and spoilers alter lift, drag, and stall speed, and describe the flap-speed and load-factor limits on flap extension

  • Describe the aerodynamics of turns: load factor in level turns, the relationship between bank angle and stall speed, and overbanking tendency

  • Explain adverse yaw, aileron drag, and the correct use of rudder in turns and in cross-controlled situations

  • Describe the aerodynamics of spins: incipient, fully developed, and recovery, and the role of the stall in spin entry

Your checkpoint

A bank-angle table giving load factor and the resulting stall-speed multiplier from 0 to 75 degrees, plus a written spin-entry and recovery sequence with the aerodynamic reason for each control input

Week 6

Principles of Flight

  • Explain ground effect, its effect on induced drag and on the ability to become airborne versus to climb, and the hazard of premature liftoff

  • Describe wake turbulence generation, its behavior relative to the generating aircraft, and avoidance procedures on takeoff and landing

  • Explain the aerodynamic effects of aircraft icing on lift, drag, stall speed, and control feel, and identify the critical surfaces

  • Describe Mach effects, critical Mach number, and shock-induced separation at a conceptual level appropriate to the private pilot certificate

Your checkpoint

A two-page summary card covering ground effect, wake turbulence avoidance, icing effects, and high-speed aerodynamics, written as a preflight briefing you could give from memory

Week 7

Principles of Flight

  • Describe the causes of and recovery from the four types of stalls: power-off, power-on, cross-controlled, and accelerated

  • Explain the aerodynamics of the region-of-reversal and elevator-trim stall scenarios and the correct recovery priorities

  • Explain how weight, CG position, and density altitude affect takeoff, climb, cruise, and landing performance

  • Describe the aerodynamic basis for V-speeds (Vx, Vy, Va, Vfe, Vno, Vne) and state how each is affected by weight and altitude

Your checkpoint

A V-speed reference table giving the definition, the aerodynamic reason for the limit, and the effect of weight, altitude, and CG for each of the six listed speeds, plus a written stall-recovery checklist for each of the four stall types

Week 8

Principles of Flight

  • Re-derive from memory the lift equation, the load-factor stall relationship, and the drag-curve relationships without reference material

  • Resolve a set of mixed scenario questions that combine two or more principles (for example, heavy aircraft in a banked turn at high density altitude) and justify each answer

  • Identify and re-study the three weakest sub-topics from the week 4 and week 7 milestone checks

  • State, in your own words, how each principle connects to a specific preflight or in-flight decision

Your checkpoint

A closed-book, 40-question self-test scored against a written answer key, with a one-page error log listing each missed concept, its root cause, and the corrective study action

Milestones

Week 2: Explain without notes why a wing stalls at a specific angle of attack regardless of airspeed, weight, or bank angle, and correctly compute stall speed at 2g

Week 4: Sketch the total drag curve from memory, label minimum-drag and best-glide speeds, and explain why flight below minimum-drag speed requires more power to fly slower

Week 6: Pass a 15-question mixed quiz on ground effect, wake turbulence, icing, and flap and turn aerodynamics with at least 80% correct

Week 7: Describe the entry, recognition, and recovery for all four stall types and for a spin, with the aerodynamic reason for each step, without reference material

Week 8: Score at least 85% on the closed-book 40-question self-test, with no missed item in the lift equation, load factor, or drag curve categories
