Radar altimeter component recognition: which item is a radar altimeter component?

• A. Height Indicators (HUD)
• B. Jet engine pressure sensor
• C. Pitot tube
• D. Flight control computer

Answer: (A)

Radar altimeter systems deliver altitude above ground by sending a radar pulse and timing its return, with the measurement feeding a display that the pilot reads. The Height Indicators (HUD) is the unit that presents that radar-derived altitude to the pilot, so it directly represents the radar altimeter’s output in a usable form. The other items belong to different systems: a jet engine pressure sensor monitors engine conditions, a pitot tube measures airspeed, and the flight control computer handles control logic. Since the HUD is the component that conveys the radar altimeter data to the aviator, it is the correct choice.
