What is the purpose of Airport Surface Detection Equipment (ASDE)?

• A. Provide weather data for the airport.
• B. Augment and confirm information obtained from visual surveillance of the airport surface or verbal reports of aircraft positions.
• C. Manage aircraft maintenance records.
• D. Control runway lighting schedules.

Answer: (B)

ASDE is all about knowing where everything is on the airport surface. It uses radar to monitor aircraft and ground vehicles on runways and taxiways, giving real-time position data that complements what you see visually and what pilots report. This extra information helps controllers confirm exact locations and spot potential conflicts, which is crucial for preventing runway incursions, especially in poor visibility or busy operations. Weather data, maintenance records, and runway lighting controls come from different systems, not ASDE. Weather is observed and transmitted separately, maintenance records are kept in upkeep systems, and lighting schedules are managed by the airport’s lighting control system.
