What is the standard altimeter setting in the United States when flying above 18,000 feet MSL?
Answer: 29.92 inches Hg
Above 18,000 feet MSL (in Class A airspace), all aircraft set their altimeters to 29.92 inches Hg standard pressure, and altitudes are referred to as 'flight levels.'
What does 'VFR' stand for and what does it require?
Answer: Visual Flight Rules — flying by outside visual reference in good weather
VFR stands for Visual Flight Rules, which require pilots to navigate by visual reference to the ground and maintain specific minimum visibility and cloud clearance requirements.
What is a 'NOTAM' in aviation?
Answer: Notice to Airmen — temporary notices about flight hazards, restrictions, or changes
A NOTAM (Notice to Airmen) is an official notice containing information about changes to aeronautical facilities, services, procedures, or hazards that pilots must know.
What does 'MSL' mean in aviation altimetry?
Answer: Mean Sea Level — the average ocean surface used as altitude reference
MSL stands for Mean Sea Level, the average ocean surface level used as the standard zero reference for measuring altitude in aviation.
What is 'relative wind' in aerodynamics?
Answer: The airflow experienced by the airfoil, opposite in direction to the aircraft's movement
Relative wind is the airflow direction and velocity as experienced by the airfoil, which flows in the opposite direction to the aircraft's path through the air.
What does 'the four forces of flight' refer to?
Answer: Lift, weight, thrust, and drag
The four forces acting on an aircraft in flight are lift (upward), weight (downward), thrust (forward), and drag (rearward). Flight is controlled by managing the balance of these forces.
