What does 'VFR' stand for in aviation?
Answer: Visual Flight Rules
VFR stands for Visual Flight Rules, the regulations governing flight conducted primarily by visual reference to the ground and horizon.
Which cloud type is associated with thunderstorms and severe turbulence?
Answer: Cumulonimbus
Cumulonimbus clouds are towering convective clouds associated with thunderstorms, lightning, heavy rain, and severe turbulence.
What is 'density altitude' and how does it affect aircraft performance?
Answer: True altitude corrected for temperature; higher density altitude reduces performance
Density altitude is pressure altitude corrected for temperature; high density altitude (hot, high, humid conditions) reduces engine power and aerodynamic lift.
What does the acronym 'METAR' refer to in aviation weather?
Answer: Meteorological Aerodrome Report
METAR (Meteorological Aerodrome Report) is a standardized format for reporting current surface weather conditions at an airport.
What is the function of an aircraft's ailerons?
Answer: Control roll by moving in opposite directions
Ailerons are control surfaces on the outer trailing edge of each wing that move in opposite directions to create differential lift and control roll.
What does 'IFR' flight require that VFR flight does not?
Answer: An instrument rating and reliance on cockpit instruments for navigation
IFR (Instrument Flight Rules) flight requires a pilot to hold an instrument rating and navigate solely by reference to cockpit instruments, typically in low visibility or clouds.
