Understanding Airport Fog Delays: A Guide for Cautious Flyers

Fog is a significant factor in aviation, often leading to flight delays and cancellations due to reduced visibility. Understanding how fog impacts airport operations can help you plan your travels more effectively.

What Causes Fog at Airports?

Fog forms when the air near the ground becomes saturated with moisture, causing tiny water droplets to suspend in the air and reduce visibility. This phenomenon can occur due to various factors, including temperature changes, humidity levels, and wind patterns. Common types of fog affecting airports include:

• Radiation Fog: Occurs during clear nights when the ground cools rapidly, cooling the air above it to the dew point.

• Advection Fog: Forms when warm, moist air moves over a cooler surface, such as a cold ocean current or a snow-covered ground.

• Upslope Fog: Develops when moist air is forced up a slope, cooling as it rises and condensing into fog.

How Does Fog Affect Airport Operations?

Fog can significantly impact airport operations by reducing visibility, which affects takeoff and landing procedures. Airports may implement various measures to ensure safety during foggy conditions:

• Instrument Landing Systems (ILS): These systems guide aircraft to the runway using radio signals, allowing landings in low-visibility conditions.

• Holding Patterns: Aircraft may be instructed to circle in a holding pattern until visibility improves enough for a safe landing.

• Diversions: If fog persists, flights may be diverted to alternate airports with better visibility.

For instance, San Francisco International Airport (SFO) often experiences morning fog, leading to reduced arrival capacity and potential delays. Flights arriving between 7 and 11 a.m. are particularly susceptible to these delays. (sfbayweather.com)
