Private Pilot Vocabulary




Question Answer
MonocoqueThe skin supports almost all imposed loads.
Semi-monocoqueThe skin is riveted to a sub-structure to maintain shape of the airframe and increase strength.
AileronsExtend from the midpoint outward to tip. Help move the plane about the longitudinal axis (Roll Left or Right).
FlapsExtend from the fuselage to midpoint. when extended the flaps move simultaneously downward to increase lift.
EmpennageVertical and Horizontal Stabilizer
Rudderattached to the vertical stabilizer and moves the nose of the airplane right to left or about the vertical axis. (Yaw Left or Right)
Elevatorattached to the horizontal stabilizer, used to move about the lateral axis. (Pitch Up or Down)
Stabilatorused as a one piece horizontal stabilizer, the stabiliator moves on a hinge as a single unit to pitch up or down.
Trim Tabattatched to the trailing edge of a control surface to lessen the resistance felt on flight controls.
Anti-servoused on a Stabilator to provide the feel of an elevator.
Oleo Strutuses a piston in enclosed in a cylinder with oil and compressed air to absorb the shocks and bumps encountered
Differential Brakingthe individual use of brakes


The Power Plant


Question Answer
Reciprocating Enginea fuel\air mixture is compressed within a cylinder then ignited.
The Four Stroke Operating CycleIntake, Compression, Power, and Exhaust
Turbine EngineAll four events of the four stoke operating cycle of a turbine engine occur simultaneously in sections.
The Induction system utilizesthe throttle and mixture controls
Intake Portair intake point on an airplane
Carburetormixes incoming air with fuel before delivering the mixture to the combustion chambers.
Carburetor ice occurs whenFuel vaporization and a drop in air pressure cause a distinct drop in temperature. If water vapor is in the air, and the temperature is at or below freezing, ice may form restricting the surface of the carburetor including the throttle valve.
Carburetor Ice may occur attemperatures of 100 F and a humidity of 50%
Carburetor Heatcauses a slight decrease in power but helps relieve carburetor icing.
Fuel injectionless susceptible to icing.
Super ChargerCompresses incoming air
Turbo Chargerpressurizes the air using a mechanism
Magnetoself contained engine driven unit that provides the electrical current to spark plugs
Detonationoccurs when fuel cylinders explode rather than burning smoothly
Help cool the engine byretarding the throttle and climb at a slower rate
PreignitionPreignition occurs when the ignition phase occurs before the normal time if this takes place retard the throttle enrich the mixture and lower the nose attitude.
Vapor Lockwhen air enters the fuel system
Fuel Strainerremoves moisture and other setiments
Red Fuel80/87
Green Fuel100/130
Blue Fuel100LL
Clear FuelJet
Oil performs what functionsLubricates internal parts, cleans the engine, and cools the engine
Cowl Flapscreate a larger path for air to escape the engine.
If Oil and cylinder head temperatures are to highyou need to enrich the mixture, reduce the rate of climb, increase air speed, or reduce the power.
The Propeller control is usedto change the pitch of the blades
In a fixed pitch propeller blank should be avoidedlow R.P.M settings with high manifold pressure
Load Meterdisplays the load placed on the altenator
Ammeterreflects current coming from the battery.
The Master Switchcontrols the entire electrical system


Flight Instruments


Question Answer
Pitot-static Instruments rely on air pressure differences to measure vertical speed and altitude these instruments use the surrounding, or static, or air pressure. Pitot pressure is used by the air speed indicator in combination with static pressure.
