Brunei DCA CPL(A) Principles of Flight · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Basic Aerodynamics: Atmosphere, Airflow and Aerodynamic Force & Airfoils, Lift Generation and the Lift Equation

  • Define ISA pressure, temperature and density lapse rates up to 11 km and compute density altitude for three worked airfield examples

  • Explain the generation of aerodynamic force from pressure distribution and Newtonian momentum change, and reconcile the two explanations

  • Derive the lift equation from CL, dynamic pressure and wing area, and solve five numerical problems for speed, area or CL with units checked

  • Sketch CL against angle of attack for two camber values and annotate the zero-lift angle, CL max and critical angle

Your checkpoint

One-page formula and definition sheet covering ISA, density altitude, boundary layer terms and the lift equation, plus five solved lift-equation problems with correct units

Week 2

Airfoils, Lift Generation and the Lift Equation & Drag: Parasite, Induced and Total Drag

  • Plot the CL-alpha curve and the CD-alpha curve on one graph and mark the induced-drag-dominated and parasite-dominated regions

  • Separate parasite drag into form, skin friction and interference, and give one airframe example of each

  • Derive the induced drag relationship with CL squared and aspect ratio, and calculate the induced drag change for a doubling of CL

  • Construct a total drag curve against speed and identify the minimum-drag speed and the speed for minimum power required

Your checkpoint

Week 3

  • Derive the thrust required curve from the total drag curve and explain its shape at low and high speed

  • Explain how power available varies with altitude and temperature for a piston engine and a propeller combination

  • Determine the maximum level speed, maximum rate of climb and maximum angle of climb graphically from the intersection of required and available curves

Week 4

Stability: Static and Dynamic, Longitudinal, Lateral and Directional & Control: Axes, Surfaces, Trim and Control Effectiveness

  • Define static and dynamic stability and classify the three longitudinal dynamic modes by period and damping

  • Explain how the centre of gravity position and the neutral point determine longitudinal static margin and pitch stability

  • Analyse the contributions of the horizontal tail, fin and wing dihedral to longitudinal, directional and lateral static stability

  • Map pitch, roll and yaw to their axes and surfaces, and describe the secondary effects of each control input

  • Explain trim systems, control effectiveness with speed and control reversal or flutter as an effectiveness limit

Your checkpoint

A stability and control summary table listing each axis, its static stability contributor, its control surface, its secondary effect and one failure or degradation mode, plus a labelled diagram of the three axes

Week 5

Stalling, Spinning and High-Angle-of-Attack Aerodynamics & Flight Envelope, Load Factor and Structural Limitations

  • Identify the factors that raise or lower stall speed, including weight, load factor, flap, ice and bank angle, and compute stall speed for a given load factor

  • Describe the stall sequence from trailing-edge separation through buffet to full stall and explain the effect of sweep and taper on tip stall tendency
