Which type of electric ground power unit provides power without moving?

• A. Stationary
• B. Towed
• C. Self Propelled
• D. Hydraulic

Answer: (A)

Electric ground power units come in different forms based on mobility. A stationary unit stays in one place and supplies electrical power to the aircraft without moving, making it ideal when the aircraft is docked at a gate or stand and you don’t need the power unit to relocate. The other options involve moving the unit to the aircraft or supplying a different type of power: towed and self-propelled GPUs are mobile and can reposition themselves to where the aircraft is, and a hydraulic unit provides hydraulic power rather than electrical power, so it wouldn’t be the right choice when specifically asked about electrical power without movement.
