11.1 Theory of Flight

11.1.1 Aeroplane Aerodynamics and Flight Controls 

Operation and effect of:

— roll control: ailerons and spoilers;

— pitch control: elevators, stabilators, variable incidence stabilisers and canards;

— yaw control, rudder limiters;

• Control using elevons, ruddervators;
• High lift devices, slots, slats, flaps, flaperons;
• Drag inducing devices, spoilers, lift dumpers, speed brakes;
• Effects of wing fences, saw tooth leading edges;
• Boundary layer control using, vortex generators, stall wedges or leading edge devices;
• Operation and effect of trim tabs, balance and antibalance (leading) tabs, servo tabs,
• spring tabs, mass balance, control surface bias, aerodynamic balance panels;

11.1.2 High Speed Flight

Speed of sound, subsonic flight, transonic flight, supersonic flight,

Mach number, critical Mach number, compressibility buffet, shock wave, aerodynamic heating, area rule;

Factors affecting airflow in engine intakes of high speed aircraft;

Effects of sweepback on critical Mach number.

11.2 Airframe Structures — General Concepts

(a)

• Airworthiness requirements for structural strength;
• Structural classification, primary, secondary and tertiary;
• Fail safe, safe life, damage tolerance concepts;
• Zonal and station identification systems;
• Stress, strain, bending, compression, shear, torsion, tension, hoop stress, fatigue;
• Drains and ventilation provisions;
• System installation provisions;
• Lightning strike protection provision.
• Aircraft bonding

(B)

• Construction methods of: stressed skin fuselage, formers, stringers, longerons, bulkheads,
• frames, doublers, struts, ties, beams, floor structures, reinforcement, methods of skinning, anti-corrosive protection, wing, empennage and engine attachments;
• Structure assembly techniques: riveting, bolting, bonding Methods of surface protection, such as chromating, anodising, painting;
• Surface cleaning.
• Airframe symmetry: methods of alignment and symmetry checks.
