Aeronautics and Safety Concepts

Drag

• The resistance an aircraft faces as it moves through the air, caused by the form and shape of the aircraft as well as the process of generating lift.

• The force that propels an aircraft forward, generated by the engines.

• The upward force that counteracts the weight of the aircraft during flight.

• The downward force acting on an aircraft due to gravity.

HAZARD: Fibre Dusts

• Generated when trimming carbon fibre and glass-fibre components, these fine dusts can cause lung discomfort and irritation.

• These dusts are fatal and should be inhaled with caution.

• Fibre dusts are harmless and do not require any protective measures.

• Ventilation booths and PPE are not necessary when working with fibre dusts.

Health and Safety

What must employers provide to ensure a safe and healthy work environment?

• Identifying and addressing hazards

• Increasing work hours for employees

• Reducing employee benefits

• Limiting safety training sessions

Innovation

• The process of introducing new ideas, methods, or technologies.

• A method of reducing costs in manufacturing.

• A strategy for increasing market share.

• A technique for improving customer service.

Wind Tunnels

• Wind tunnel testing provides valuable real-world data that complements computer simulations.

• Wind tunnels are only used for testing full-size aircraft.

• Wind tunnels can only simulate the effects of wind on stationary objects.

• Wind tunnel tests are not useful for improving aircraft designs.

Propulsion System

• A system used in aircraft to provide thrust, enabling flight.

• A type of fuel used in jet engines.

• A mechanism for controlling the altitude of an aircraft.

• A device that measures the speed of an aircraft.

Metallurgical Properties

• The aesthetic qualities of metals in jewelry making.

• The physical and chemical properties of metals that determine their suitability for specific applications, such as strength, durability, and resistance to stress and fatigue.

• The environmental impact of metal extraction and processing.

• The historical significance of metals in ancient civilizations.

Lift

• The downward force generated by the weight of the aircraft.

• The upward force generated by the wing’s camber and angle of attack, which counteracts the force of gravity and keeps an aircraft in the air.

• The horizontal force that propels the aircraft forward.

• The force that causes the aircraft to rotate around its center of gravity.

Wingtip Vortex (Wake Vortex)

• A type of cloud formation that occurs at high altitudes.

• A spiral of air created by the pressure difference between the top and bottom surfaces of the wing, resulting in drag and turbulence that reduces efficiency and can affect other aircraft.

• A phenomenon that occurs only during takeoff and landing.

• A method used to increase lift on an aircraft wing.

Control Systems

• The systems that allow pilots to control an aircraft’s flight surfaces, such as ailerons, elevators, rudders, and flaps.

• The navigation systems used to guide an aircraft from one location to another.

• The communication systems that allow pilots to talk to air traffic control.

• The engines that provide thrust to an aircraft during flight.
