In-depth Notes on Private Pilot License - Aircraft General

Aircraft Type: Piston engines are most commonly used in light single and twin-engine aeroplanes.
Structure: Main structural components include the fuselage, wings, tailplane, and control surfaces.
Types of Airframe Construction:
- Monocoque: All loads carried by the outer skin.
- Semi-Monocoque: Loads distributed between outer skin and internal supports (formers and stringers).
- Truss or Girder Design: Framework design using rods to form triangles for strength.

Cylinder: Where power is produced; consists of a barrel (made of high-grade steel) and a head (usually aluminum).
Piston: Moves within the cylinder, aided by combustion; features compression rings, oil control rings, and oil scraper rings.
Connecting Rod: Links piston to crankshaft.
Crankshaft: Converts piston movement to rotary motion.
Crankcase: Houses the crankshaft and supports engine structure.
Valves: Allows air-fuel mixture in and exhaust gases out; typically made from heat-resistant steel.

Ignition Timing: Occurs around 20° before TDC (Top Dead Center) for optimal combustion.
Detonation Prevention: Controlled via fuel grade, mixture settings, and engine temperatures.

Principle: Utilizes incompressibility of fluids to transmit force.

Components:
- Reservoir, Accumulators, Pumps, and Actuators.
Actuators: Convert hydraulic pressure into mechanical motion (linear and rotary).

Electricity Basics: Direct Current (DC) vs. Alternating Current (AC).
Generators: Convert mechanical energy into electrical energy, maintaining system charge.
Battery Types: Lead acid for lighter aircraft; Nickel Cadmium for higher demand systems.
Voltage Regulation: Maintains output to prevent overcharging.

Types of Fuel Tanks: Bladder type, integral, and rigid tanks.
Fuel Delivery Methods: Gravity feed in high-wing designs versus pressure systems in low-wing designs.
Filters: Essential for removing debris before engine fuel intake; crucial for safety.
Vapor Lock Prevention: Avoid situations causing fuel to vaporize in lines, especially in high temps.

Types: Fixed gear and retractable gear systems.
Actuation: Powered by hydraulic or electrical systems for gear extension/retraction.
Braking Systems: Operate through friction; designs include internal expanding shoe brakes and disc brakes.

Pitot-Static Systems: Measures pressure for ASI, altimeter, and VSI; includes both pitot and static ports.
Airspeed Indicator Protocols: Errors from instrument wear, pressure changes, and temperature variations.
Altimeter Mechanics: Measures altitude based on pressure differences; calibrated against sea level pressure.
Gyroscopic Instruments: Artificial horizon, direction indicator, turn coordinator; depend on principles of gyroscopic motion.

Engine Fire On Ground: Turn off fuel supply, mixture to idle, keep cranking.
Engine Fire In Air: Follow emergency procedure, kill fuel supply, follow engine failure protocols.
Cabin Fire: Control the source, use fire extinguishers, ventilate cabin while monitoring conditions.

Must be current, issued and renewable by the SACAA; key for operational legality.

Operators must adhere to the specific guidance set forth in the aircraft flight manuals.

Must carry various certificates and documents onboard to comply with regulations.

Limited maintenance is permissible for outlined tasks; pilot must keep appropriate records.

Familiarization with onboard emergency systems and procedures is critical for safety.
