What does a flashing green light to an aircraft in flight mean?

• A. Continue takeoff
• B. To return for landing
• C. Hold
• D. Taxi

Answer: (B)

The main idea here is how air traffic control communicates with pilots in flight using light signals. These signals have specific meanings that tell the pilot what to do without talking on the radio. A flashing green light received in flight means the pilot is being instructed to return for landing. In other words, you should head back toward the airport and prepare to land under ATC instructions.

Think of it as a clearance in disguise: a steady green would directly authorize a landing, while a flashing green signals you to reverse course toward landing rather than continuing the current approach. The other options don’t fit this signal: continuing a takeoff isn’t dictated by a flashing green, holding patterns are indicated by different signals, and taxi movements apply to aircraft on the ground, not in flight.
