Chapter 2 fill in blank

"blank" control the lateral movements of the aircraft, the "blank" controls the longitudinal movements, and the "blank" controls the directional movements

elevator, elevator, rudder

cables that travel completely through bulkheads require the use of a "blank" and should not be deflected more than "blank" from a straight line

fairlead, 3 degree

an autogryo is an aircraft with an horizontal rotor that is "blank" and turns due to the passage of air "blank" through the rotor

freespinning, upward

swaging tools generally have a "blank" dimensions in an attempt to avoid defective or inferior swages

go & no go

Fluids always move from "blank" to "blank" pressure. This principle explains the spanwise movement of air flow from the bottom of the wing "blank" and upward around the wing creating spillage over the wingtip called "blank"

high, low, outward, vortex

Density varies "blank" with temperature and "blank" with pressure

inversely, directly

the collective pitch control is operated with the "blank" hand and is used to make pitch angle changes to "blank" the main rotor blades

left, all

The acute angle the wing chord makes with the "blank" axis is called angle of incidence

longitudinal

structural alignment is the "blank" of the main structural component related to the longitudinal datum line parallel to the aircraft centerline and the lateral datum line parallel to the line joining the "blank"

position, wingtips

helicopters with tandem rotors use the pedals to tilt the main rotors. when the "blank" pedal is pushed forward the aft rotor moves to the "blank"

right, left

An object that tends to return to equilibrium is said to have positive "blank" stability

static

there is a "blank" of lift between the advancing and retreating blade

symmetry

a groove or knurl around the end of the barrel of a "blank" can be used to identify the "blank" threads

turnbuckle, left hand

Velocity increases and pressure decreases on the "blank" of the wing

upper surface

hard landing and abnormal flight experiences prompt a check of the wing "blank" and angle of "blank"

dihedral, incidence

The boundary layer is the layer of "blank" closest to the surface and its behavior is controlled in order to minimize "blank" drag and skin friction drag

fluid, pressure

A pilot can increase the lift of an aircraft by increasing the "Blank"

AOA

autorotation is possible through a freeewheeling unit, a special "blank" mechanism, which automatically disengages the engine in the event of its failure

clutch

the most common method of safety wiring is the "blank" however; a "blank" method can be used for smaller screws and tight spaces

double twist, single-wire

the blade with the decreased angle of attack tends to flap "blank"

down

According to Bernoulli's principle, fluid flowing through a constriction experiences an "blank" in speed

increase

A body at rest does not move unless a force is applied to it is Newton's "blank" law and is known as the law of "blank"

First, Inertia

The study of objects in motion through the air and the "blank" governing that motion come from the Greek combination of "aero" and "blank"

Force, Dyne

atmospheric pressure is measured in "blank" with a "blank"

Hg, Barometer

As an aircraft descends atmospheric pressure "blank", the amount of oxygen in the air "blank", and temperature "blank"
