  1. Fuel and Pneumatics CW3 Dave Mercado

  2. OBJECTIVE • Develop Student Instructor Pilot’s understanding of the Fuel and Pneumatic systems.

  3. PNEUMATICS • First of all, the three sources of air are: • ENGINE • APU • Ground source

  4. BLEED AIR USES • HEATING SYSTEM • ENGINE ANTI-ICE VALVE • ENGINE INLET ANTI-ICE VALVE • ERFS

  5. PNEUMATIC AIR INLET ANTI-ICE VALVE STARTER #2 ENG HEAT START CONTROL VALVES APU CROSS BLEED VALVES STARTER #1 ENG INLET ANTI-ICE VALVE GROUND AIR INLET

  6. Pneumatic Air • ANY QUESTIONS???

  7. FUEL SYSTEM • System Diagram • Associated Emergency Procedures • Fuel by the numbers
