Answer :
Final answer:
The correct answer is A) Green and white flashes. Standard airport rotating beacons for civilian airports flash green and white lights to signal their location and operational status to pilots.
Explanation:
The correct answer is A) Green and white flashes. The standard airport rotating beacons use specific color combinations to signal the type of airport and its operational status. For civilian airports, the beacon flashes green and white lights. A green light flashes once per cycle, while the white light flashes twice. This color coding helps pilots identify the airport's location during night operations or when visibility is poor. Military airfields similarly use a rotating beacon but with two distinctive quick white flashes followed by a green flash, differentiating them from civilian airports.
