Used to determine the wind direction and approximate speed.

• A. Altimeter
• B. Windsock
• C. Hygrometer
• D. Barometer

Answer: (B)

A windsock is used to gauge wind direction and give a rough sense of wind speed. It catches the air and aligns with the wind, pointing in the direction the wind is blowing toward. The more it is extended and taut, the stronger the wind is, while a slack or drooping sock indicates lighter winds. This quick visual cue is especially important for takeoffs and landings, including drone operations, where wind can affect stability and control. The other instruments measure altitude (altimeter), humidity (hygrometer), and atmospheric pressure (barometer), none of which tell you wind direction or speed.
