Thunderstorms and ATC

Thunderstorm avoidance is important to pilots, sure, but did you know that it’s also a critical activity for air traffic controllers?

Early reroutes from TMU can offer more efficient weather avoidance.

Key Takeaways:

Thunderstorms pose a significant challenge to air traffic, disrupting flight efficiency and making standard ATC conflict prediction tools less effective, requiring controllers to rely on manual skills and proactive clearances.
Air Traffic Control utilizes specialized units like Traffic Management Units (TMU) for strategic rerouting around weather and Center Weather Service Units (CWSU) for real-time, detailed weather advisories and forecasts.
ATC employs sophisticated weather radar to provide controllers with real-time visual data on convective activity, enabling them to issue critical advisories and guide pilots safely.
Pilots must communicate early and specifically when requesting weather deviation clearances, which are primarily lateral and require clear understanding of allowed maneuvers and procedures for returning to course.

One of the most impactful elements of the NAS (national airspace system), arguably one of the most dangerous, is thunderstorms. They terrorize our skies and our airports every summer. They’re an unavoidable fact of life in aviation. So let’s look at how pilots and ATC work together to deal with them.

‘Tis the season my aviation enthusiasts. Thunderstorms are in full swing. The time has come for the madness of deviations, re-routes, and closing airports. There isn’t a more chaotic time in aviation, particularly going into complex and congested airports. Has Denver International ever had less than 100 microbursts in a single day between June and August? Unlikely.
