Study Notes
Aerodynamics
- Increasing the angle of attack increases lift production until a critical angle where the wing stalls.
- Flaps on aircraft increase lift in low airspeed conditions.
- Lateral stability is the tendency of an aircraft to return to level flight after a roll disturbance.
Aircraft Components & Systems
- Higher camber on an aircraft wing results in a higher lift production.
- Longitudinal instability results in uncontrollable pitching of the aircraft.
- Pitching involves rotating the aircraft about its lateral axis.
- The air cycle machine conditions outside air, ensuring proper flow rate, and providing cooling.
- Emergency oxygen supplies provide supplemental oxygen to passengers and crew during aircraft survival.
- Hypoxia can be mitigated by having a supplemental oxygen supply or cabin pressurization during high-altitude flights.
- Increasing cabin temperature from 20°C to 25°C would require the Environmental Control System (ECS) to increase cooling airflow.
- Engine inlets, nacelles, and wing leading edges are typically protected by bleed air anti-ice systems.
- Anti-icing system malfunction can lead to icing, reduced efficiency, and loss of lift on wings.
- An Emergency Locator Transmitter (ELT) sends out a distress beacon.
- Bimetallic fire detectors are entirely mechanical, triggered by heat, and not susceptible to random failures or power failures.
- Titanium is used in aircraft construction due to its high strength-to-weight ratio and high thermal resistance.
- A weight and balance record ensures the aircraft's center of gravity (CG) remains within the acceptable limits.
- Rigging affects the aircraft's center of gravity by ensuring symmetrical component placement on the center line for stability.
- Yawing is a change in direction caused by the rudder control surface.
- "All Up Weight" is the total weight of an aircraft at the beginning of a flight.
Aircraft Fuel Systems
- Gravity draining typically involves using a drain valve at the lowest point in the fuel tank to allow the fuel to flow naturally.
- Fuel quantity indicators inform the pilot of the remaining fuel level.
- Water contamination in fuel is visually detectable by looking for a water layer in the sample.
Aircraft Hydraulic Systems
- Hydraulic pressure relief valves prevent overpressure damage within the hydraulic system.
- Aircraft utility hydraulic systems provide power to various systems, e.g., thrust reversers, flaps, and slats.
Aircraft Braking System
- Disc brakes slow the aircraft's movement and are used on the wheels of the aircraft on the ground.
- Hydraulic systems provide power for flight controls, landing gear, and brakes.
- Maintaining hydraulic fluid levels ensures efficient maintenance.
- Flight controls feel independent with rods and pulleys, full feel with boosters, reduced feel when hydraulically powered, and no feel in the absence of an artificial feedback system.
Aircraft Landing Gear System
- Dual hub construction is commonly used in high-performance aircraft for its strength and lightweight.
- Brake system failure can result in runway overrun and possible loss of control during landing operations.
- SAF 1400-6 (Change of Serviceability and Repair Log) is typically updated after landing gear maintenance.
Aircraft Servicing Forms
- Aircraft servicing form 1400 contains details of the aircraft, servicing, and rectification.
Additional Questions
- Ice accumulation on aircraft instruments causes inaccurate readings, including Airspeed.
- Smoke detectors detect smoke in the cabin by sensing changes in air particles.
- Fire detection systems typically use temperature sensors to detect fires.
- Aircraft windshield defogger systems are powered primarily by electrical power. -Oleo struts are common landing gear struts in modern aircraft.
