Military airports are often distinguishable from civilian airports by their unique features, especially at night. While the presence of military aircraft, vehicles, personnel, and equipment might indicate a military airport, these may not always be visible or specific enough for identification in low-light conditions. Instead, military airports can be identified by their unique lighting patterns, specialised navigational aids, restricted airspace, and the absence of commercial activity. Specifically, a military airport can be identified at night by looking out for a red and white rotating beacon or flashing green lights.

What You'll Learn
Flashing green lights
To identify a military airport at night, one must look out for flashing green lights or a red and white rotating beacon. The flashing green lights are used by air traffic control to indicate various points of reference or directions for pilots. They are also used to signal to aircraft on the ground that they are cleared to taxi to the takeoff runway or away from the runway back to their stand.
A flashing green light directed at aircraft on the ground means that the aircraft is cleared to taxi. This could be either to the takeoff runway or away from the runway back to their stand. Pilots must keep a good lookout for other aircraft while maneuvering as the likelihood of a collision is highest when the aircraft is on the ground.
In the USA, flashing red and green pulses together are used to indicate "Exercise extreme caution". This signal is not an ICAO standard and is therefore not universally adopted.

Red and white rotating beacon
Military airports use specific lighting patterns for identification, and a red and white rotating beacon is a standard signal used worldwide. This rotating beacon is typically placed atop the control tower, above other airport buildings, to indicate the location of the airport to pilots at night.
The red and white rotating beacon emits a characteristic rotating light pattern that helps pilots locate the airport. It produces alternating beams of red and white light, which rotate to provide a clear signal to aircraft approaching at night. This helps pilots easily locate the airport in low-visibility conditions.
The beacon may be an omnidirectional flashing xenon strobe, or it may rotate at a constant speed to produce the visual effect of flashes at regular intervals. The tower and beacon are painted with aviation gloss orange and white. The beacon should be inspected daily for functionality, and the glass should be inspected twice a month to ensure it is clear.
In the early days of aviation, pilots relied on landmarks for navigation during the day, and bright light sources, such as bonfires, were experimented with for nighttime navigation. The shift to LED lights has brought longer life, lower power consumption, and reduced maintenance costs to airport beacons.

Aerodrome beacon
An aerodrome beacon, also known as an airport beacon, rotating beacon, or aeronautical beacon, is a structure installed at an airport or aerodrome to indicate its location to aircraft pilots at night or in low-visibility conditions. They are typically mounted on top of a towering structure, often the control tower, to ensure visibility above other airport buildings.
In the United States, the Federal Aviation Administration (FAA) has established specific rules for airport beacons, including the flashing rate and the colours used. For example, in busy airspace (Class B, C, D, and E surface areas), airport beacons are often turned on during the day when ground visibility is less than 3 miles. At some airports, Air Traffic Control (ATC) staff can control the beacons manually, while other airports use photoelectric cells or timers to control the beacons automatically based on the amount of ambient light.
Heliports with beacons typically exhibit the Morse letter "H" (4 short flashes) at a rate of 3 to 4 groups per minute. Aerodrome beacons play a crucial role in helping pilots locate airports and providing information about the type of airport through the colour and pattern of lights displayed.

Lighting patterns
Military airports use specific lighting patterns to aid pilots in identifying them at night or in low-visibility conditions. These lighting patterns are standardised worldwide and are endorsed by aviation authorities for nighttime operations.
The most common lighting pattern used to identify a military airport at night is a red and white rotating beacon. This beacon emits alternating beams of red and white light, which rotate to provide a clear signal to aircraft approaching at night. The red and white rotating beacon is typically placed atop the control tower, making it visible above other airport buildings. The rotating beacon produces flashes similar to those of a lighthouse, with the light rotating at a constant speed to create the visual effect of flashes at regular intervals.
Another lighting pattern used to identify military airports is flashing green lights. These flashing green lights are often used by air traffic control and can indicate various points of reference or directions for pilots. The flashing green lights are distinct from civilian airport lights, which typically flash white and green. Military airport beacons differentiate themselves from civilian beacons by inserting two quick white flashes between the green flashes.
In addition to these lighting patterns, military airports may also have taxiway centreline lights that are green in colour. These taxiway lights outline the edges of the taxiway and aid in controlling the movement of aircraft and vehicles on the ground. At non-towered military airports, the lighting may be controlled by a Flight Service Station (FSS), with FSS personnel adjusting the lighting intensity and patterns as needed or when requested by pilots.
The lighting patterns at military airports are essential for aviation safety, especially during nighttime or low-visibility conditions. These lighting aids help pilots locate the airport, navigate to the runway, and maintain the proper glide path for landing.

Light signals
Military airports use specific lighting patterns for identification. Pilots can identify a military airport at night by looking for a red and white rotating beacon or flashing green lights. These lights help pilots locate military airports effectively in low-visibility conditions.

This type of beacon is endorsed by aviation authorities for nighttime operations.

They are also used on heliports, with beacons exhibiting the Morse letter "H" (4 short flashes) at a rate of 3 to 4 groups per minute.
In addition to these standard identifiers, there are other types of lights and beacons that can assist pilots in locating and navigating military airports at night. For example, some airports have taxiway centerline lights that are green, and approach light systems that provide a visual transition from instrument flight to visual flight for landing.
Overall, light signals play a crucial role in identifying military airports at night, ensuring safe and efficient operations for pilots and aircraft.

Frequently asked questions
Military airports can be identified at night by their unique lighting patterns, specialised navigational aids, restricted airspace, and the absence of commercial activity.
Military airports often use specific patterns of runway and taxiway lights that differ from civilian airports. These lights might flash or change colour in ways that signify military operations. For example, a red and white rotating beacon or flashing green lights.
Military airports may have distinctive navigational aids or signals that don't follow the standard visual setups of civilian airports. These could include specific codes in their runway lights that civilian pilots might not recognise.
Some areas around military airports are designated as restricted airspace, which is often noted on aviation charts. This could indicate military activity, especially during the night.
Military airports typically do not have commercial flight operations. This can be inferred from the lack of typical commercial airport activity such as terminal lights or scheduled flights during late hours.
