In standard meteorological terminology for aviation, what is the Beaufort scale used to determine?

Introduction / Context:
Accurate wind information is vital for aerodrome operations. While direction is indicated by devices like windsocks and measured by vanes, the standardized qualitative–quantitative categorization of wind intensity is commonly expressed using the Beaufort scale. This question reinforces that association.

Given Data / Assumptions:

• Aviation context, surface winds.
• Choice among intensity, direction, or unrelated parameters like aircraft height.

Concept / Approach:
The Beaufort scale assigns integer levels linked to ranges of wind speed and observed environmental effects, offering a convenient strength descriptor. It does not provide direction, and it is unrelated to aircraft altitude, which is determined from pressure altimetry (QNH/QFE) and reported as altitude/height/flight levels.

Step-by-Step Solution:
Identify what the Beaufort scale classifies: wind strength.Exclude direction (windsocks, vanes) and aircraft height (altimeters).Select the intensity option.

Verification / Alternative check:
Meteorological guides and METAR/TAF training materials frequently pair Beaufort terminology with descriptive wind-force levels (e.g., “fresh breeze”).

Why Other Options Are Wrong:

• Direction: handled by wind vanes and reported in degrees true/ magnetic.
• Aircraft height: unrelated to wind scales; measured via pressure instruments and radio altimeters.
• None: invalid because the Beaufort scale specifically exists for wind strength.

Common Pitfalls:
Equating any wind-related instrument with direction; ignoring that Beaufort is a categorical scale rather than a directional indicator.

Final Answer:
Strength (intensity) of winds
