A lighted civilian land airport's rotating beacon flashes which colors?

White and green.

  1. White and yellow
  2. Green, yellow, and white
  3. White and green ✔

Why: The AIM lists white and green for civilian land airports. White and yellow marks a water airport, and green, yellow, and white marks a heliport. Military airports add two quick white flashes.

Huh, didn't know that: The AIM warns pilots not to rely on the beacon alone to decide whether weather is VFR or IFR.

The dad joke
How many pilots does it take to change a light bulb? One. He holds it and the world revolves around him.
