Question 1

What is the standard altimeter setting in the United States when flying above 18,000 feet MSL?

Accepted Answer

29.92 inches Hg

Answer

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.'

Question 2

What does 'VFR' stand for and what does it require?

Accepted Answer

Visual Flight Rules — flying by outside visual reference in good weather

Answer

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.

Question 3

What is a 'NOTAM' in aviation?

Accepted Answer

Notice to Airmen — temporary notices about flight hazards, restrictions, or changes

Answer

A NOTAM (Notice to Airmen) is an official notice containing information about changes to aeronautical facilities, services, procedures, or hazards that pilots must know.

Question 4

What does 'MSL' mean in aviation altimetry?

Accepted Answer

Mean Sea Level — the average ocean surface used as altitude reference

Answer

MSL stands for Mean Sea Level, the average ocean surface level used as the standard zero reference for measuring altitude in aviation.

Question 5

What is 'relative wind' in aerodynamics?

Accepted Answer

The airflow experienced by the airfoil, opposite in direction to the aircraft's movement

Answer

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.
