Did you know commercial jets usually have a "secret" engine hidden in the tail? 🤫 It is called the Auxiliary Power Unit (APU). This small turbine engine plays a massive role when the aircraft is parked on the ground. Since the main engines are usually turned off at the gate, the APU kicks in to generate electricity for the aircraft's systems. Most importantly, it powers the Air Conditioning (AC) to keep the cabin cool before departure. It is the unsung hero of ground operations! ❄️ 👉 Follow us

THE "EXTRA" ENGINE OF A PLANE CALLED AN APU Did you know that there is a third engine on twin-engine aircraft or a fifth engine on a quadjet? Yes, that engine is not a jet engine like the ones you see under the wings, but it is usually hidden in the rear of an aircraft. It is also not as big as those jet engines. It is actually small and not a jet engine per se. This is what you call an APU or Auxiliary Power Unit. This is the loud sound you hear while boarding an aircraft. Also, if you look at

What really powers a jet on the ground? Not the big engines — but a tiny turbine hiding in the tail. The Auxiliary Power Unit (APU) jumpstarts the entire aircraft, runs the electrics, and keeps the cabin cool before takeoff. Without it? Your plane is nothing more than a 200-ton paperweight. Next time you land, look out for that little exhaust puffing away at the tail — that’s the APU doing its job. #fyp #avgeek #planespotting #pilot #aviation #APU #AircraftSystems #JetEngines #FlightSafety #Airc
