Question 1

A pilot observing a rapidly falling barometric pressure reading during flight should anticipate which condition?

Accepted Answer

Approaching low-pressure system with deteriorating weather

Answer

Rapidly falling barometric pressure indicates an approaching low-pressure system, which typically brings deteriorating weather including clouds, precipitation, and turbulence.

Question 2

What type of fog forms when warm, moist air moves over a cooler surface?

Accepted Answer

Advection fog

Answer

Advection fog forms when warm, moist air moves horizontally over a cooler surface, cooling the air below its dew point.

Question 3

During a PIREP, a pilot reports 'OCNL MOD CHOP.' What does this indicate?

Accepted Answer

Occasional moderate turbulence causing rapid bumps without aircraft attitude change

Answer

Occasional moderate chop (OCNL MOD CHOP) indicates intermittent rapid bumpiness without abrupt changes in aircraft attitude, affecting less than 1/2 of the time.

Question 4

A wind shear encounter on final approach causes the airspeed to suddenly decrease and the aircraft to sink below the glideslope. What is the MOST likely meteorological cause?

Accepted Answer

Headwind shear transitioning to a tailwind

Answer

When a headwind transitions to a tailwind, the aircraft loses airspeed and lift, causing it to sink below the intended glidepath.

Question 5

Which layer of the atmosphere contains the tropopause, and what is its approximate altitude at mid-latitudes?

Accepted Answer

Troposphere boundary, at approximately 36,000 feet MSL

Answer

The tropopause marks the boundary of the troposphere, occurring at approximately 36,000 feet MSL at mid-latitudes, lower at the poles and higher at the equator.
