  1. High Performance Power Plants

  2. Complex Airplanes

  3. Complex Airplanes • Retractable landing gear • Flaps • Controllable pitch propeller

  4. High Performance Airplane

  5. High Performance Airplane • Engine of over 200 Horsepower

  6. Manifold • What is a manifold?

  7. Manifold • What is a manifold? • A pipe with many lateral outlets to connect one with others • Airplanes often have an intake manifold and and exhaust manifold

  8. Manifold Pressure • A measure of the pressurized air in the intake manifold measured in inches of mercury • With the engine off, what does the manifold pressure normally register at sea level • At 5,000 feet?

  9. Fuel Injection Systems • Carburetor Heat • Auxiliary Fuel Pump • Fuel Flow Indicator • Vapor Lock

  10. Engine Monitoring • Exhaust Gas Temperature Gauge (EGT) • Best Economy Mixture • Best Power Mixture • Cylinder-Head Temperature Gauge (CHT)

  11. Abnormal Combustion • Detonation • Preignition

  12. Induction Icing • Impact Ice • Induction System Icing • Alternate Air Source

  13. Turbocharging Systems • Manifold Pressure Gauge • Absolute Ceiling • Service Ceiling • Critical Altitude

  14. Supercharging • The compressor is driven by the crankshaft through an intricate gearing system, which takes considerable horsepower from the engine to operate

  15. Constant-Speed Propellers • Blade Angle • Pitch Angle • Geometric Pitch Angle • Effective Pitch Angle

  16. Constant-Speed Propellers • Propeller Blade Slip • Governing Range • Propeller Control

  17. Constant-Speed Propellers • Feathering Propellers Vs Nonfeathering • Multiengine airplanes • Reduce drag • Prevent further engine damage

  18. What is the largest reciprocating engine to be successfully used in an airplane?

  19. What is the largest reciprocating engine to be successfully used in an airplane? • R4360 • Eight of them used on the Spruce Goose.

  20. What was the diameter of the propellers used on the Spruce Goose?

  21. What was the diameter of the propellers used on the Spruce Goose? • 17 feet 2 inches

  22. What is propeller efficiency?

  23. What is propeller efficiency? • Ratio of thrust horsepower to brake horsepower

  24. What is a Q-tipped propeller?

  25. What is a Q-tipped propeller? • A Hartzell propeller with the tip of each blade bent back 90 degrees. It normally replaces a propeller of larger diameter.

  26. What are the advantages of a Q-tipped propeller?

  27. What are the advantages of a Q-tipped propeller? • Reduce cabin noise • Increased Blade-to-ground clearance • Less erosion and other damage caused by ground debris.

  28. If you feather a propeller and then make a wheels-up landing, what direction will the propeller bend?

  29. If you feather a propeller and then make a wheels-up landing, what direction will the propeller bend? • backward

  30. If you strike a propeller while you are in powered flight, which direction will it bend?

  31. If you strike a propeller while you are in powered flight, which direction will it bend? • forward

  32. What material was used to make propellers on early aircraft? • Why?

  33. What material was used to make propellers on early aircraft? • Why? • Wood • It is light, strong, flexible and can be easily worked.

  34. After wood, what was the next popular material for making propellers?

  35. After wood, what was the next popular material for making propellers? • Metal

  36. Does a propeller have the same geometric pitch throughout its length? • Why?

  37. No • Tip of blade is moving faster than the hub. Tip would stall

  38. Noise Abatement • Some airports have specific routes you have to fly to try to avoid populated areas • Ground noise levels can often be reduced by reducing power

  39. If you have a turbocharging system with manual controls, how might you encounter an overboost annunciator segment light?

  40. Descending from a high altitude • Applying takeoff power to a cold engine.

  41. What is the maximum glide configuration in a Bonanza? • Landing Gear?

  42. What is the maximum glide configuration in a Bonanza? • Landing Gear - Up • Flaps?

  43. What is the maximum glide configuration in a Bonanza? • Landing Gear - Up • Flaps - Up • Cowl Flaps?

  44. What is the maximum glide configuration in a Bonanza? • Landing Gear - Up • Flaps - Up • Cowl Flaps - Closed • Propeller?

  45. What is the maximum glide configuration in a Bonanza? • Cowl Flaps - Closed • Propeller - Pull for low RPM • Airspeed?

  46. What is the maximum glide configuration in a Bonanza? • Propeller - Pull for low RPM • Airspeed - 105 KTS

  47. What is the emergency descent configuration of the Bonanza? • Power?

  48. What is the emergency descent configuration of the Bonanza? • Power - Idle • Propeller?

  49. What is the emergency descent configuration of the Bonanza? • Power - Idle • Propeller - High RPM • Landing Gear?
