Chapter 1 - Becoming a Pilot and Principles of Flight Flashcards
What are the two main points of pre-flight?
1) That all required documents are on-board
2) To ensure that the airplane is in safe condition for flight
What are the three required documents to look for during pre-flight?
1) Airworthiness certificate
2) Aircraft registration certificate
3) Airplane checklists
When walking to the airplane, what should you look for?
Fluid leaks or obvious hazards
What should you and shouldn’t you do concerning the airplane checklists?
You should be familiar with them, but you should NOT memorize them
What is the general direction of the exterior pre-flight inspection?
Left seat to tail, then counter clockwise around plane
What is the propeller arc?
The space the propeller will turn in
What does good cockpit management require?
Materials and equipment are readily available and well organized
What are the four main materials needed in the cockpit?
1) Pen/Pencil and Paper
2) Airport diagram
3) Terminal area and sectional charts
4) American Flyers flight planing form
Important seat position tip
Keep the seat position consistent, especially early in training
What is the predominant aerodynamic for for enabling an airplane to fly?
The lifting force
What are airfoils?
Structures or surfaces that are designed to generate an aerodynamic force when they interact with the air
Examples of airfoils
Wings, Propellers, Stabilizers, Helicopter blades
What are the four basic forces of flight?
1) Lift
2) Weight
3) Thrust
4) Drag
What is lift
Upward force created by an airfoil
What direction does lift act?
Perpendicular to wings
What force does lift oppose?
Weight
With regards to lift, why is air accelerated rearward and downward by the wings?
Due to the shape of the wing and its inclination or angle relative to the flight path of the airplane
What does the amount of lifting force depend on?
The weight/load of the airplane
Is there an Angle of Attack indicator in the C172?
No
What is the only reference to Angle of Attack in the C1172 and why?
As airspeed changes, the AOA changes, maintaining the same lifting force
Wings will create lift equal to weight unless what?
The critical Angle of Attack is exceeded, resulting in a stall
Are pitch and Angle of Attack the same?
No! Level pitch could be greater than any angle of attack depending on power/airspeed/flight path
What direction does weight act?
Towards the center of the earth; downward
What force does weight oppose?
Lift
What does weight encompass?
The actual weight of the aircraft and everything in it, please aerodynamic loads
What direction does thrust act?
Forward
What force does thrust oppose?
Drag
On most planes, what creates thrust?
The propeller + engine
What direction does drag act?
Rearward
What force does drag oppose?
Thrust
What factors cause drag from friction to vary?
The airspeed and angle to the relative wind
What speed produces the least amount of drag?
The Best Gliding Speed
Describe the function of the Elevator and its location
Controls pitch, located on the tail
Describe the function of the Ailerons and their location
Controls roll, on wings
Describe the function of the rudder and its location
Controls yaw, located on the vertical stabilizer
What keeps the longitudinal axes aligned with the flight path?
The rudder
What direction yaw does left aileron produce?
Right yaw
What direction yaw does right aileron produce?
Left yaw
Together, what do the elevator, ailerons, and rudder control?
The plan’s attitude
How should you think with regards to control?
Pressure; not resulting movement
Describe pitch
Movement about the lateral, or Y, axis
Describe Roll
Movement about the longitudinal, or x, axis
Describe yaw
Movement about the vertical, or z, axis
What is attitude?
The position of the nose and wings in relation to the horizon
What is the purpose of Trim?
To relieve control pressure and reduce pilot fatigue
What do you need to do when changing bank attitude?
Use rudder to control adverse yaw
What is the result of lowering flaps?
Lowering flaps may cause an increase in camber, wing area, and drag
What does more camber and wing area produce?
The same lift at a lower airspeed
What is camber?
The camber of an airfoil is the characteristic curve of its upper and lower surfaces
Should you extend flaps at high speeds?
No, you may damage them
Vfe
The maximum flaps extended speed
For the C172, what is Vfe and how is it noted?
85 KIAS, the end of the white arc on the ASI
How can you find the stall speed with flaps extended?
The low end of the white arc on the ASI
What instrument measures power?
The tachometer, read in rpm
Why do you need to be aware what is behind the airplane when starting the engine?
Propeller wash
How do you clear the propeller arc when starting the engine?
Turn on the rotating beacon, then yell “CLEAR” while looking outside the plan (not at the checklists/charts)
How long should it take the engine to start while cranking?
10-15 seconds of cranking
What is the most important gauge to check while starting the engine?
Oil pressure
What is the color indication for Mandatory markings?
Red background, white numbers
What is the color indication for Location markings?
Yellow boarders, black background, yellow numbers/letters
What is the color indication for Direction markings?
Black boarders, yellow backgrounds, black numbers/letters
What color is the runway centerline?
White
What does the runway number denote?
The magnetic heading while facing down the runway, rounded to the nearest 10 degrees with the trailing 0 dropped
What color marks an unusable surface?
Yellow
What do displaced thresholds indicate?
The usable portion of the paved surface
What do arrows on the runway indicate?
An area usable for taxi and takeoff, but not for landing
