Bob Hawk Tel. The main responsibility of air traffic controllers is to provide safe separation between aircraft. Controllers provide other services, including weather advisories, insofar as their main workload permits.
Pilots receive weather information from a variety of sources.
Aircraft dispatchers provide weather reports and forecasts to commercial pilots before a flight, including weather that may affect the safety of the flight. They also provide weather updates while a flight is underway. The National Weather Service provides forecasts and inflight weather advisories of conditions that were not forecast prior to departure. FAA provides pre-flight weather briefings and inflight advisories. It is the flight crew's responsibility to become knowledgeable about the weather aloft before departure.
