Which indicator suggests a military airfield?

1. A white and red rotating beacon.

2. White flashing sequence lights (strobes).

3. A green and dual-peaked white rotating beacon.

4. A high-intensity approach lighting system.

The correct answer is: A green and dual-peaked white rotating beacon.

The indicator that suggests a military airfield is characterized by a green and dual-peaked white rotating beacon. This specific combination of colors and design signifies the presence of a military installation. The green light often indicates a military airfield, while the dual-peaked white light complements it and is used to differentiate from civilian airport beacons. Other types of lighting mentioned serve different purposes. For instance, a white and red rotating beacon typically identifies a civilian airport, and white flashing sequence lights are often utilized in various lighting systems for traffic control and other visual guidance, but do not specifically signal military airfields. High-intensity approach lighting systems are primarily utilized to enhance the visibility of runways and approach paths and do not imply military use either. Understanding these distinctions is crucial for pilots in recognizing different airfield types and ensuring proper navigational decisions.
