CPL Aviation Meteorology 2

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

Improving visibility and clearing skies

Answer

Stable high-pressure ridge building overhead

Answer

Decreasing wind speeds at altitude

Question 2

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

Accepted Answer

Advection fog

Answer

Radiation fog

Answer

Upslope fog

Answer

Frontal fog

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

Continuous moderate turbulence with significant altitude excursions

Answer

Occasional mild turbulence with minimal passenger discomfort

Answer

Moderate chop causing momentary loss of aircraft control

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

Tail wind shear transitioning to a headwind

Answer

Crosswind component increasing rapidly

Answer

Updraft followed by a downdraft

Answer

Stratosphere, at 50,000 feet MSL

Answer

Mesosphere, at approximately 80,000 feet MSL

Answer

Thermosphere, at approximately 100,000 feet MSL

Question 6

What condition is indicated by a surface temperature-dewpoint spread of 2°C or less with rapidly increasing relative humidity?

Accepted Answer

Potential for fog or low cloud formation

Answer

Ideal VFR flying conditions

Answer

Severe clear air turbulence likely

Answer

Thunderstorm development imminent

Question 7

A Cumulonimbus cloud that has a distinctive anvil-shaped top (incus) indicates what stage of thunderstorm development?

Accepted Answer

Answer

Cumulus (developing) stage

Answer

Dissipating stage

Answer
