A metal propeller may be statically balanced by. adding varnish to the lighter blade. removing metal from the opposite blade. adding or removing lead wool to the hollow blade roots.

Mechanical vibration relating to propellers in a piston powered aircraft. is due to the crankshaft at intermittent power settings. is due to the lead lag of the propeller compared to the engine. is due to the power stroke of the engine and may have a more detrimental effect than aerodynamic vibration.

Aerodynamic Correction Factor (A C F). corrects for static balance. is indicated in the form of degrees and minutes of pitch. corrects for dynamic balance.

Operation with the engine at maximum boost should be limited to. prop at fine to prevent overstressing the engine. prop at course to prevent overstressing the engine. prop at windmill to prevent overstressing the engine.

Damage to a leading edge can be blended in comparison to a blade face. by maintaining a smooth depression. by not exceeding 25% of the chord. at a steeper angle.

The longitudinal clearance between the nose wheel and the propeller on a tricycle geared propeller is. 9 inches. 18 inches. 1/2 inch.

A tracking check compares. 2 Adjacent blades. 2 Opposite blades. any 2 blades.

A line of indentations at one blade section can be. blended within limits. left for up to 12 months. declared unserviceable.

Propeller vibration due to a problem with propeller installations would have a. the same frequency as turbine vibration. lower frequency than turbine vibration. higher frequency than turbine vibration.

Preloading propeller blades before installation prevents. blade distortion. blade flutter. aerodynamic imbalance on the blades.

When unfeathering a propeller, the blade should be put into what position to stop propeller overspeed?. Negative pitch. Fine pitch. Coarse pitch.

Blade angle is measured using a. clinometer. propeller protractor. bevel protractor.

In the Beta range, angle of attack increases. The fuel flow increases, and what else increases?. Fuel temperature. EPR and fuel temperature. RPM and EGT.

With a propeller defect, the frequency of vibration will be. higher than a auxiliary gearbox defect. lower than a turbine defect. higher than a turbine defect.

Blending of propeller blade defects refers to the. repainting of blade tips after cropping. matching of paint finishes for appearances. conversion of rough or sharp edges into smooth depression.

Removal of material from the propeller blade tips, resulting in a reduction in propeller diameter is called. tipping. cropping. topping.

Prior to using the universal propeller protractor. ensure the propeller blade is at the horizontal. determine the reference blade station. check date stamp for serviceability.

To fit a new front cone to a prop shaft firstly. etch the propeller serial number to the rear face. cut in half with a hacksaw and etch a unique serial number to both halves. coat in Engineers blue to ensure seating in the propeller front boss.

Blade tracking is adjusted by. adding lead wool to the blade shank. re-seating the propeller on the front and rear cones. by fitting shims to the propeller shaft hub.

Which of the following functions requires the use of a propeller blade station?. Indexing blades. Propeller balancing. Measuring blade angle.

To conduct a power check of an internal combustion engine requires. coarse pitch setting and advance the throttle to the target RPM. fine pitch setting and advance the engine to the target RPM setting. fine pitch setting and advance the engine to the max RPM setting.

The power output of a turboprop engine is checked by. reference RPM. reference Thrust. reference Torque.

Immediately after blending out damage to a blade the repair must be. re-protected against corrosion. crack checked. balanced.

How is the efficiency of a turbo prop engine assessed?. By correcting propeller RPM for ambient Air temperature and barometric pressure. By comparing compressor and propeller RPM against a reference figure. By comparing torque meter pressure against a reference figure.

The limits for a tracking check are. 1/4 inch maximum difference between adjacent blades. 1/8 inch maximum difference between opposite blades. 1/8 inch maximum difference between all blades.

After a lightning strike. the prop must be tracked. the propeller shaft should be checked for concentricity. the heater elements should be checked for continuity and insulation.

After overspeeding to 110%. no action is required. return propeller for overhaul. remove propeller for inspection.

Indentations to the blade face are measured. individually. individually and collectively. collectively.

When a propeller has had a report of overspeeding. procedure is dependant on the extent of overspeeding. the propeller must be removed and sent to the manufacturer. the propeller must be removed and tracked.

The most significant effect of stone chips on a propeller is. thrust output of the propeller. structural integrity of the propeller. aerodynamic capability of the propeller.

Ground running an aircraft with a fixed pitch prop with its tail into wind causes the engine RPM to. increase. stay the same regardless of wind direction. decrease.
