FUNDAMENTALS OF FLIGHT

Question 1

DEFINE MOTION

Answer 1

ACT OF CHANGING PLACE OR POSITION

Question 2

DEFINE ACCELERATION

Answer 2

THE RATE OF CHANGE OF SPEED AND OR VELOCITY OF MATTER WITH TIME.

Question 3

DEFINE SPEED

Answer 3

THE RATE OF MOVEMENT IN TERMS OF DISTANCE MEASURED IN AN ALLOTTED AMOUNT OF TIME.

Question 4

DEFINE VELOCITY

Answer 4

THE QUICKNESS OR SPEED OF AN OBJECT IN A GIVEN TIME AND DIRECTION.

Question 5

NEWTONS FIRST LAW

Answer 5

AN OBJECT AT REST WILL REMAIN AT REST, OR AN OBJECT IN MOTION WILL REMAIN AT MOTION UNLESS ACTED ON BY AN OUTSIDE FORCE.

Question 6

NEWTONS SECOND LAW

Answer 6

IF AN OBJECT MOVING WITH UNIFORM SPEED IS ACTED ON BY AN EXTERNAL FORCE, THE CHANGE OF MOTION OR ACCELERATION, WILL BE DIRECTLY PROPORTIONAL TO THE AMOUNT OF FORCE AND INVERSELY PROPORTIONAL TO THE MASS OF THE OBJECT BEING MOVED.

Question 7

NEWTONS THIRD LAW

Answer 7

FOR EVERY ACTION THERE IS AN EQUAL AND OPPOSITE REACTION

Question 8

BERNOULLI”S PRINCIPLE

Answer 8

A FLUID FLOWING THROUGH A TUBE REACHES A CONSTRICTION , CAUSING THE SPEED OF THE FLUID TO INCREASE, WHILE THE PRESSURE DECREASES.

Question 9

DEFINE LIFT

Answer 9

THE FORCE THAT ACTS IN AN UPWARD DIRECTION TO SUPPORT AIRCRAFT IN AIR. COUNTERACTS WEIGHT. LIFT MUST BE GREATER THAN OR EQUAL TO WEIGHT TO MAINTAIN FLIGHT.

Question 10

DEFINE WEIGHT

Answer 10

THE FORCE OF GRAVITY ACTING DOWNWARD ON THE AIRCRAFT AND EVERYTHING ON THE AIRCRAFT.

Question 11

DEFINE DRAG

Answer 11

THE FORCE THAT TENDS TO HOLD AN AIRCRAFT BACK. CAUSED BY THE DISRUPTION OF AIR ABOUT THE WINGS, BODY, AND ALL PROTRUDING OBJECTS ON THE AIRCRAFT. DRAG RESISTS MOTION.

Question 12

DEFINE THRUST

Answer 12

THE FORCE DEVELOPED BY THE AIRCRAFT ENGINE THAT ACTS IN THE FORWARD DIRECTION. THRUST MUST BE GREATER THAN DRAG IN ORDER FOR FLIGHT TO BE SUSTAINED.

Question 13

WHAT IS THE LONGITUDINAL AXIS?

Answer 13

AN IMAGINARY REFERENCE LINE RUNNING FROM NOSE TO TAIL DOWN THE CENTER OF THE AIRCRAFT.

Question 14

LATERAL AXIS

Answer 14

AN IMAGINARY REFERENCE LINE RUNNING PARALLEL TO THE WINGS

Question 15

VERTICAL AXIS

Answer 15

IMAGINARY REFERENCE LINE RUNNING FROM THE TOP TO THE BOTTOM OF THE AIRCRAFT.

Question 16

AILERONS

Answer 16

MOVABLE CONTROL SURFACE THAT MOVES AIRCRAFT ABOUT ITS LONGITUDINAL AXIS CAUSING “ROLL”

Question 17

ELEVATORS

Answer 17

MOVABLE CONTROL SURFACE THAT MOVES AIRCRAFT ABOUT ITS LATERAL AXIS CAUSING “PITCH”

Question 18

RUDDER

Answer 18

MOVABLE CONTROL SURFACE THAT MOVES THE AIRCRAFT ABOUT ITS VERTICAL AXIS CAUSING “YAW”

Question 19

TAIL ROTOR

Answer 19

COUNTERACTS THE TORQUE OF THE MAIN ROTOR BY INCREASING OR DECREASING THE AMOUNT OF HORIZONTAL THRUST THE TAIL ROTOR PRODUCES, MOVING THE HELICOPTER ABOUT ITS VERTICAL AXIS.

Question 20

CYCLIC STICK

Answer 20

CONTROLS HELICOPTER ABOUT ITS LATERAL AND LONGITUDINAL AXIS BY CHANGING DIRECTION OF LIFT.

Question 21

FLAP

Answer 21

LEADING/TRAILING EDGE CREATES EXTRA LIFT BY LENGTHENING THE TOP SECTION OF THE WING RESULTING IN MAXIMUM LIFT TO REDUCE TAKEOFF RUNS AND LANDING ROLLOUT.

Question 22

SPOILER

Answer 22

USED TO DECREASE WING LIFT BY DESTROYING SMOOTH AIR FLOW OVER WING SURFACES CREATING A MORE PREDICTABLE LANDING GLIDE SLOPE.

Question 23

SPEED BRAKES

Answer 23

HINGED OR MOVABLE CONTROL SURFACES USED TO REDUCE THE SPEED OF AN AIRCRAFT.

Question 24

SLATS

Answer 24

MOVABLE CONTROL SURFACE ATTACHED TO LEADING EDGE OF WING

Question 25

DEFINE COLLECTIVE

Answer 25

THE ANGLE OF ATTACK OF THE ROTOR BLADES OF A HELICOPTER.WHEN THE COLLECTIVE IS LOWERED TO ZERO AND THE ROTOR BLADES ARE LEVEL, NO LIFT IS ACHIEVED.

Question 26

DEFINE ANGLE OF ATTACK

Answer 26

THE ANGLE AT WHICH THE AIRFOIL OR FUSELAGE MEETS THE FLOW OF AIR

Question 27

DEFINE AUTOROTATION

Answer 27

A METHOD OF ALLOWING A HELICOPTER TO LAND WITHOUT USING ENGINE POWER.AS A HELICOPTER IS DESCENDING, THE COLLECTIVE IS LOWERED ALLOWING REVERSE AIR FLOW THROUGH THE ROTOR TO MAINTAIN RPM.WHEN THE HELICOPTER REACHES A PRE DETERMINED ALTITUDE, COLLECTIVE IS INCREASED TO CREATE INERTIAL ENERGY INTO LIFT TO CUSHION THE LANDING.

Question 28

WHAT ARE THE COMPONENTS OF A BASIC AIRCRAFT HYDRAULIC SYSTEM?

Answer 28

A RESERVOIR FOR HYDRAULIC FLUID
A PUMP
TUBING
A SELECTOR VALVE TO DIRECT FLOW
AN ACTUATING UNIT TO CONVERT PRESSURE INTO USEFUL WORK.

Question 29

LIST LANDING GEAR COMPONENTS.

Answer 29

SHOCK STRUT ASSEMBLY
TIRES
WHEEL BRAKE ASSEMBLY
RETRACTING AND EXTENDING MECHANISM
SIDE STRUTS AND SUPPORTS.
