Aerospace Revision Flashcards
What is Newtons Third Law and how does it relate to lift?
A. for every action there is an equal and opposite reaction.
B. wings are forced upwards, pushing air upwards therefore the wings get pushed upwards.
What is Bernouli’s principle and how does it relate to lift?
A. an increase in the speed of fluid with a decrease of pressure or a decrease in the fluids potential energy.
B. faster moving air produces less pressure, causing the wing to lift toward the area of low pressure.
What is the Iterative problem-solving process? (in order)
- define the problem.
- brainstorm solutions.
- pick a solution.
- implement the solution.
- evaluate/review the results.
Who was the first woman to fly across the Atlantic and when was this?
Amelia Earhart, June 1928
Who completed the first powered flight and when was this?
Orville Wright (The Wright Brothers), December 1903
What is a ‘waters thinking habit’?
a spectrum of strategies that foster problem-solving and thoughtful reflection about systems of interest.`
What is systems thinking?
a way to approach issues by looking at them as systems.
what is a balancing/reinforcing loop?
A. cycle in which circles of cause and effect that counter a change with a push in the opposite direction.
B. a circular system in which they are self-reinforced.
what is lift?
a positive force, perpendicular to the flight direction, generated by wings, air pressure below the wing is greater than air pressure above the wing.
What are the types of clouds found at Low level altitudes?
A. Low level - Stratus, Stratocumulus, cumulus, nimbostratus, cumulonimbus.
What types of clouds are found at Medium level altitudes?
A. Altostratus, altocumulus, cumulonimbus.
What types of clouds are found at High level altitudes?
A. Cirrostratus, cirrocumulus, cirrus, cumulonimbus.
What are the 6 main instruments found in an aircraft?
Airspeed indicator, Heading indicator (HSI), Altimeter, Attitude indicator, Turn coordinator, vertical speed indicator (VSI).
What process does a jet engine undergo?
Air is sucked in through the intake of the engine -> air is then compressed -> compressed air is mixed with fuel and then combusts -> air is then shot out through exhaust creating thrust.
Formula for aspect ratio?
Wingspan ÷ chord average
what are the two types of drag and how do they work?
A. Parasitic drag - all drag that is not associated with lift.
B. Induced drag - drag on an aerofoil which arises from the development of lift.

what is an electrical system?
An aircraft electrical system is a self contained network of components that generate, transmit, distribute, utilize and store electrical energy.
What is a Pneumatic system?
Pneumatic systems, commonly known as vacuum or pressure systems, power the heading and attitude indicators in most general aviation (GA) aircraft, and in many aircraft, also power the autopilot and de-ice systems.
What is a hydraulic system?
