The flight deck accommodates the pilot and co-pilot side by side with a third crewmember seated behind the pilot on the starboard side. The automatic flight control system was developed by Thales Avionics (formerly Sextant Avionique) and BAE Systems (formerly Marconi).
The primary navigation system, an AC Delco Carousel IVA, consists of three inertial navigation systems each with a dedicated digital computer. The navigation suite also includes two VHF omnidirectional radio rangers linked with an instrument landing system (VOR/ILS), an automatic direction finder (ADF), two distance measuring equipment (DME), and a navigation marker. The aircraft is equipped with two RCA AVQ-X weather radars, two Thales AHV-5 radio altimeters and a Rockwell Collins terrain collision avoidance system (TCAS).
