Which device on modern large aircraft is primarily responsible for monitoring flight parameters and interfacing with autopilot systems?

• A. Inertial reference unit
• B. VHF transceiver
• C. Flight management computer
• D. Weather radar

Answer: (C)

Flight management computer acts as the central processor for flight planning and autopilot guidance. It continuously monitors key flight parameters—like altitude, airspeed, vertical speed, and position—by using data from sensors and the active flight plan. It checks performance and constraints, computes the optimal trajectory, and converts that into guidance commands for the autopilot and flight director to follow. The autopilot then uses those commands to control the aircraft’s flight path and thrust, keeping you on the planned route. Other systems play supporting roles: the inertial reference unit provides attitude and heading information, weather radar detects weather, and the VHF transceiver handles communications, but they don’t manage the ongoing flight guidance and autopilot interfacing like the flight management computer does.
