Flashcards: Aviation Atmosphere Weather and Regulations — 24 cards

Aircraft — definition?

A vehicle that can travel through the air.

Control surface — role?

Controls aircraft motion around axes.

Flight level — function?

Indicates aircraft altitude relative to standard pressure.

Phonetic alphabet — purpose?

Standardized spelling of letters for clear communication.

Pressure formula — expressing?

Pressure = Force / Surface area.

Nautical mile — conversion?

1.852 km.

Knot — definition?

Speed of 1 nautical mile per hour.

Aircraft axes — three?

Longitudinal, lateral, vertical.

Flaps — function?

Increase lift during flight.

Forces on aircraft — four?

Weight, lift, thrust, drag.

Roll control — which?

Ailerons control roll around longitudinal axis.

Lift origin — upper airfoil surface?

Majority of lift due to lower pressure.

Airframe — components?

Wing, fuselage, stabilizers, landing gear.

Landing gear — purpose?

Taxi, absorb stresses, retract during flight.

Turbojet — thrust?

Ejects high-energy gas stream.

Pilot oxygen mask — donning steps?

Pull, place, adjust, release.

Main aircraft circuits?

Electrical, hydraulic, pneumatic.

Taxiway — function?

Connects runways, terminals, facilities.

Runway orientation?

Aligned with dominant regional wind.

Center of gravity — effect?

Affects stability and maneuverability.

Standard atmosphere pressure?

1013.25 hPa at sea level.

Boyle's law — statement?

V = P x V / P' for gases.

Gas expansion — cause?

Lower pressure at higher altitude.

Tropical cyclone — key features?

Low pressure, high winds, heavy rain.
