200

A single piece, horizontal tail surface on an airplane that serves as both a horizontal stabilizer and an elevator.

Stabilator

200
This engine temperature gauge (or measurement) is most commonly used for engine leaning.

Exhaust Gas Temperature (EGT)

200

This is one of the main purposes of feathering a propeller.

Reduce parasite drag.

200

This is a process of increasing pressure of the induction air by use of an engine-driven pump.

Supercharging

200

This type of fuel container installed in the aircraft can be replaced without having to remove large sections of the aircraft skin...

Rubber Bladder or Bladder Tanks
400

The following are three examples of secondary flight controls.

Flaps, trim, and spoilers.

400

Mostly in high performance aircraft, pilots may need to change the fuel mixture to this at higher speeds to optimize engine efficiency.

Lean the mixture (the mixture has become too rich).

As an aircraft's airspeed increases, pilots may need to slightly "lean" the mixture at higher speeds, especially in high-performance aircraft, to optimize engine efficiency by compensating for the increased airflow and slightly richer mixture that can occur at high speeds; however, the primary factor affecting fuel mixture adjustment is altitude, where the decreasing air density necessitates leaning the mixture to maintain the proper air-to-fuel ratio.

This describes the operating principles behind a constant speed propeller...

Propeller RPM (blue) lever sets desired spring tension on flyweight governor which sets a target RPM. Any change to propeller RPM causes flyweights to either collapse inward or fly outward opening up a valve between the engine oil and propeller hub which modifies the angle of the propeller blades subsequently returning engine to target RPM.

In a multi-engine airplane oil leaving the propeller hub and back through the governor and to the engine causes the propeller blades to do what?

400

This is a process of increasing pressure of the induction air by use of an exhaust-gas pump.

Turbocharger

400

Used to cool and lubricate fuel pumps.

Fuel itself that the fuel pump is pressurizing.

600

Applying rudder force that results in a yaw AND roll is known as this...

Aerodynamic coupling

600

A mechanical plunger that forces additional fuel through the main discharge nozzle of the carburetor when the throttle is moved towards the open position.

Accelerator pump

600

This feature is designed to prevent the propeller from going past a certain preset blade angle that could result in an excessive increase in drag and in extreme cases could restrict airflow to "blanket" the horizontal stabilizer, causing a nose down pitching moment.

Low-Pitch Stop

Note: This is NOT the same as the anti-feathering pins!

600

This location is where the manifold pressure (MAP) gauge on an aircraft measures air pressure in the intake manifold...

Just AFTER the throttle valve

600

This type of fuel container is integrally installed in the aircraft wing.

"Wet wing"

800

This type of flap produces the least amount of Coefficient of Lift (CL) for a given angle of attack (AOA).

Plain flap

Which flap type produces the most amount of coefficient of lift for a given AOA?

800

* Daily Double *

This carburetor feature is designed to draw air from the float chamber to the discharge nozzle to maintain proper fuel air mixture.

Air bleed

800

In training aircraft, this device stores engine oil pressure from the governor for the purpose of practicing in-flight engine shutdowns and restarts.

Unfeathering accumulator

800

This device is found in turbocharged or supercharged engines and helps to cool pressurized air by directing ambient air over a heat exchanger.

Intercooler

800

Fuel system icing inhibitor (FSII) that prevents formation of ice in fuel vents.

Prist

1000

This center of gravity location combined with this AOA likely causes the deepest stall (meaning a more challenging recovery).

Aft center of gravity and high AOA.

1000

This 12:1 mixture of fuel and air, when burned, leaves no uncombined oxygen or free carbon and typically is the optimal mixture for engine power.

Stoichiometric Mixture Ratio

1000

Three possible causes of propeller overspeed...

Broken speeder spring, loss of nitrogen in the propeller hub, stuck pilot valve

1000

As the deck pressure decreases, this device will increase oil pressure at the exhaust bypass valve, which in turn closes the waste gate.

Density Controller

1000

Primary purposes of VLO (retract) and VLE (gear extended)

VLO (retract): reduce the load on the hydraulic pump while raising the gear

VLE (extended): prevent damage to any extended gear doors
