A flight director is a highly sophisticated system that electronically collects the information provided by a number of instruments, feeds this information into a computer and presents it in two visual displays. The two instruments that provide this visual display are a horizontal situation indicator (HSI) and an attitude director indicator (ADI). Usually the flight director installation is combined with an autopilot system. The entire package is then known as a flight control system. 7, record 3, English, - horizontal%20situation%20indicator

Different manufacturers give other names to the components of their systems. The HSI is sometimes called the "pictorial navigation indictor" (PNI) and the ADI is sometimes called the "flight command indicator." 7, record 3, English, - horizontal%20situation%20indicator

L'ensemble directeur de vol est un système très sophistiqué qui rassemble électroniquement l'information fournie par plusieurs instruments, introduit cette information dans un ordinateur et l'expose sur deux affichages visuels. Les deux instruments qui fournissent l'affichage visuel sont l'indicateur de situation horizontale (HSI) et l'indicateur du directeur d'assiette (ADI). Habituellement, l'ensemble directeur de vol est couplé au système de pilotage automatique. Le groupe complet porte alors le nom de système de contrôle de vol. 6, record 3, French, - indicateur%20de%20situation%20horizontale
