WC-130Js carry a basic crew of five: pilot, co-pilot, navigator, flight meteorologist and weather reconnaissance loadmaster. The pilot, who serves as the aircraft commander, and the co-pilot man the flight controls. The navigator keeps track of the aircraft's position and movement and monitors radar to avoid tornadic activity. The flight meteorologist acts as flight director and observes and records meteorological data at flight level using a computer that encodes weather data every 30 seconds. The weather reconnaissance loadmaster collects and records vertical meteorological data using a parachute-borne sensor known as a dropsonde. It measures and encodes weather data down to the ocean surface.
Co-located with the National Hurricane Center in Miami, Fla., is a small group of Air Force Reserve civilian personnel, assigned to the 53rd WRS. The supervisory meteorologist of the unit serves as Chief, Aerial Reconnaissance Coordination, All Hurricanes, better known as CARCAH.
These personnel are responsible for coordinating Department of Commerce requirements for hurricane data, tasking weather reconnaissance missions, and monitoring all data transmitted from weather reconnaissance aircraft.
Charleston AFB, S.C., Homestead Air Reserve Base, Fla., and Patrick AFB, Fla., are alternate locations for the Hurricane Hunters if a storm hits the Gulf of Mexico near Keesler.
