PPGS Lesson 6.4 | Aircraft Systems: Fuel Injection Systems

Welcome back to Epic Flight Academy’s Private Pilot Ground School! In this Aircraft Systems lesson, Certified Flight Instructor Mike Thompson explains how the fuel injection system in the Cessna 172S delivers fuel to the engine for smooth combustion and reliable performance. You’ll learn how each component—including the fuel tanks, selector valve, auxiliary fuel pump, fuel/air control unit, and fuel distribution unit (spider valve)—works together to start and maintain engine operation during flight. This lesson helps student pilots understand how proper fuel management ensures safe and efficient flight performance. #PrivatePilotGroundSchool #EpicFlightAcademy #PilotTraining #AviationEducation #AircraftSystems #LearnToFly 📘 Video Chapters 0:00 – Introduction with Instructor Mike Thompson 0:38 – Fuel Injection Systems in the Cessna 172S 1:01 – Fuel Injection System Schematics 1:06 – Wing Tanks 1:18 – Fuel Quantity Transmitter 2:07 – Fuel Tank Drain Valve 2:54 – Fuel Selector Valve & Fuel Selector Drain Valve 3:20 – Fuel Reservoir Tank 3:52 – Auxiliary Fuel Pump 4:25 – Firewall 4:37 – Fuel Shutoff Valve Knob 5:18 – Fuel Strainer 5:26 – Engine-Driven Fuel Pump 5:51 – Fuel/Air Control Unit 6:34 – Fuel Distribution Unit (Spider Valve) 🎓 Start Your Pilot Training Journey: https://epicflightacademy.com/prequal...
