Question 1

Which METAR sky condition code indicates a ceiling that makes VFR flight illegal under FAA regulations in controlled airspace?

Accepted Answer

BKN025

Answer

BKN025 (broken ceiling at 2,500 feet) creates a ceiling below the 3,000-foot AGL threshold, making VFR flight illegal in Class B, C, D, and E controlled airspace without a clearance.

Question 2

Mountain wave turbulence is MOST severe at which location relative to the mountain ridge?

Accepted Answer

Immediately on the leeward side at ridge altitude

Answer

The most severe turbulence in mountain waves typically occurs just downwind of the ridge at or slightly below ridge altitude, where rotor and wave action are most intense.

Question 3

What does the term 'LLWS' represent in aviation weather, and what is the standard threshold altitude for this phenomenon?

Accepted Answer

Low-Level Wind Shear below 2,000 feet AGL

Answer

Low-Level Wind Shear (LLWS) refers to sudden changes in wind speed or direction at or below 2,000 feet AGL, posing significant hazards during approach and departure.

Question 4

A pilot notices that the altimeter setting has changed from 29.92 to 30.12 inches Hg during cruise flight at constant altitude. If the altimeter is not reset, the aircraft is actually flying at what altitude relative to indicated?

Accepted Answer

200 feet lower than indicated

Answer

Each 0.01-inch change in altimeter setting equals approximately 10 feet; an increase of 0.20 inches means actual altitude is 200 feet lower than indicated if not reset.

Question 5

Which condition is associated with the formation of clear ice on an aircraft?

Accepted Answer

Flight through large supercooled water droplets at temperatures between 0°C and -10°C

Answer

Clear ice forms when large supercooled water droplets spread over a surface before freezing, typically in temperatures between 0°C and -10°C, creating a smooth, dense, and heavy ice accretion.
