Finding the airport and taxiing are slightly more difficult compared to daylight hours.

Summary

  • Spotting airports at night is particularly challenging since they blend with the surrounding dark landscape.
  • Pilots must ensure they have the correct airport beacon in sight to avoid landing at the wrong airport at night.
  • Taxiing at night is more challenging, as airports lack overhead lighting and forward visibility is reduced.

 

The majority of most pilots’ flight time is logged during daylight hours. A lot of training is required to take place during the daytime, and many more passenger flights occur during the hours between sunrise and sunset. Aside from cargo pilots who fly many more nighttime flights, roughly 60-75% of an airline pilot’s flight time occurs during the daytime. Flying at night, though easier in some ways, comes with challenges. This article will discuss two key points: finding the airport and taxiing.

Spotting the airport

Identifying an airport at nighttime is a skill that pilots develop during training and continue to hone throughout their careers. As unbelievable as it may seem to the non-flying population, spotting airports at night (even large airports) is significantly more difficult than finding airports during the day. While airports stand out during daylight hours, they disappear at night. This is especially true if not located in an urban center; airports are many square miles of dark concrete and level terrain that easily blend perfectly with a non-urban background at night.

 

Runway lighting makes the landing area easy to see, but this is only true when pilots are flying within 30 degrees of the runway’s extended centerline. Most of the lights at airports are not omnidirectional but are intended to display the surface when viewed straight-on. Spotting an airport at night usually starts with the pilots looking for the airport’s rotating beacon, a white and green alternating light, one of the few omnidirectional lights on the field. Once pilots know where the airport beacon is, they have the context to continue looking for the runway they have been designated to land on.

Visual approaches at night

As obvious as it sounds, it’s important for pilots to make sure they have the correct airport beacon in sight at nighttime. There are countless examples of airline-serving airports near civilian airports with beacons that look identical from the air. Airline pilots have lined up (and sometimes landed at) the incorrect airport at night because of this, and the secondary airport’s runway orientation is very similar to what they expected. In sincerity, visual approaches to smaller airports at night are some of the most demanding approaches pilots fly. This is why it’s crucial to back up every one of these visual approaches with an instrument approach to the same runway.

Taxiing

Taxiing planes at night, whether airliners or Cessnas, is again more difficult than during daylight hours. Even when pilots are intimately familiar with the airport they’re at, nighttime conditions provide an added challenge when operating on the ground. As mentioned, airports are enormous dark spaces at night. Taxiway lighting and directional signs help guide the way, but seeing far ahead of the plane at night at a big airport is nearly impossible. Unlike city streets or highways lit every few meters, airports lack overhead lighting, which drivers are accustomed to during the night. Airports are very dark once away from the light of the terminal buildings and ramps.

 

Pilots tend to taxi slower at unfamiliar airports at night compared to the daytime to give themselves time to identify and confirm the taxiways they have been cleared to operate on. Pilots can look ahead and see their taxi route easily during the day, but the forward visibility at night is reduced exponentially. Many pilots now have moving targets on taxi diagrams to depict where they are at the airport. This added situational awareness is beneficial during nighttime, as well as during low-visibility operations.

 

Flying visual approaches and taxiing at night come with a few added challenges. However, spotting other traffic at night, getting shortcuts from ATC, and finding a smooth ride are all easier at night. Like anything else, flying at night has tradeoffs compared to flying during the day. Many pilots prefer nighttime operations once acquainted with the differences.
