First to respond: Instrument, flight control systems Airmen
Staff Sgt. Joshua Stokes, 185th Iowa Air National Guard instrument and flight control technician, calibrates and adjusts probes that measure fuel quantity on a KC-135 Stratotanker, June 3, 2010, McConnell Air Force Base, Kan. Fuel probes are replaced almost every week, or when needed, ensure the aircraft maintains a correct measure of fuel. The instrument and flight control systems shop is the first to respond if anything malfunctions with avionics systems, radar, video display, automatic flight control and fuel management systems.
