What does ADIRU stand for?

• A. Automatic Directional Inertial Reference Unit
• B. Air Data Inertial Reference Unit
• C. Aerodynamic Data Inertial Reference Unit
• D. Aircraft Data Inertial Reference Unit

Answer: (B)

ADIRU stands for Air Data Inertial Reference Unit. This unit is critical in modern aircraft systems, including the A320, as it integrates and processes both air data and inertial reference information. The ADIRU provides essential data such as altitude, airspeed, and aircraft position, which are vital for navigation, flight control, and autopilot operations. This combination of data from air data and inertial sensors allows for accurate and reliable flying characteristics, particularly during various phases of flight. The correct understanding and recognition of what ADIRU represents emphasizes its importance in avionic systems and contributes to safe flight operations.
