Which three signals are received by the AIM-120 control section electronics from the guidance section?

• A. Pitch, yaw, and roll
• B. Pitch, yaw, and elevation
• C. Roll, pitch, and altitude
• D. Yaw, pitch, and thrust

Answer: (A)

The signals flowing from guidance to control cover three axes of motion: pitch, yaw, and roll. Pitch commands tilt the nose up or down, yaw commands swing the vehicle left or right, and roll commands rotate the missile about its forward axis to keep the attitude and stability as it maneuvers. The control section uses these three commands to deflect fins or canards and steer toward the target. Signals like elevation, altitude, or thrust aren’t the direct three-axis control inputs used here—elevation/altitude relate to position, and thrust is propulsion, not a guidance-to-control steering command.
