| Question | Answer |
|---|---|
| Blades are twisted to optimize the performance of the propeller based on | of the propeller based on variable operating conditions |
| The propeller blade is an airfoil which propels the airplane through the air by converting the rotating power of the engine into | thrust |
| Propellers are classified according to | pitch configuration. |
| is the angle of the blades with relation to the plane of rotation and is a significant variable affecting the | Pitch |
| a one-piece prop with a single fixed blade angle. The pitch (blade angle) must be high enough to offer good cruising performance yet low enough to achieve acceptable takeoff and climb characteristics. | Fixed Pitch |
| a prop which allows the adjustment of blades to any desired angle during flight. | Controllable Pitch |
| a prop used with a governor, that automatically provides constant RPM by counteracting the forces acting on the propeller to change the blade angle within a preset range. | Constant Speed |
| a prop which allows blades to be rotated to a high positive angle to stop rotation (windmilling) after an engine is shut | Full Feathering |
| The propeller blade is an airfoil which propels the airplane through the air by converting the rotating power of the engine into | the airplane through the air by converting the rotating power of the engine into thrust. |
| a device, generally mounted on and driven by the engine, which senses and controls engine speed (RPM) by hydraulically adjusting the blade angle of the propeller. | Prop Governor |
| Pitch is changed | Hydraulically using engine oil |
| A full-feathering propeller system is normally used only on t | only on a multi-engine aircraft |
| The _________change the position of the pilot valve by utilizing centrifugal force | Flyweights |
| When engine RPM is slower than the propeller control setting, the speeder spring holds the pilot valve down and oil flows to the propeller in a full-feathering system and from the propeller in a constant-speed system. | True |
| If an engine failed on the multiengine engine aircraft with a constant speed propeller to what angle of attack would the propeller go to? | full feathered |
| What position are the flyweights in the prop governor when the blade is moving toward high pitch? | overspeed position, flyweights are slung outward |
| Name the 2 types of prop governors: | full feathering and constant speed |
| How much complex aircraft time do you need before taking your commercial pilot check ride? | 10 Hours |
| What is the purpose of the oil pump within the prop governor? | Boost oil pressure |
| The pitch of a constant speed propeller is changed though? | Hydraulically actuated with oil pressure. |
| In a full feathering prop governor the oil flows to the _________in the overspeed condition. | To the engine sump |
| The flyweights and speed spring with in the governor control________ of the _________. | Position of the pilot valve. |
