PT1 CHP2 Aircraft Structure Flashcards
What are the major wings components?
Airfoils (wings)
Spars
Ribs
Wingtip
Aileron
Wing flap
Skin
What are the major empennage components?
Vertical Stabilizer
- Rudder
Horizontal Stabilizer
- Elevator
- Trim Tabs
What are the major powerplant components?
Propeller
Engine
Cowling
What are some types engine types?
SEL (Single-engine Land)
MEL (Multi-engine Land)
What are the major fuselage components?
Longerons
Struts
Bulkhead
What are the landing gear configurations?
Tricycle (2 in back; 1 in front)
Conventional/Taildragger (1 in back; 2 in front)
Float
Ski
What are the 4 forces of flight?
Lift, generated by the airfoil
Weight, force of gravity
Thrust, created by the powerplant
Drag, occurs when moving through air
What are the 2 types of cockpits?
Traditional (6 pack)
Glass (G1000)
What are the 6-pack instruments?
Pitot-Static
- ASI
Static
- Altimeter
- VSI
Gyroscopic
- Attitude Indicator
- Heading Indicator/Compass
- Turn Coordinator
What is the tachometer?
Indicates how fast the propeller is spinning in RPMs
What is the Hobbs meter?
Indicates flight hours in hours and minutes (0.10 = 6 minutes)
What are the 2 main screens in a glass cockpit and what do they indicate?
Primary Flight Display (PFD), simplified version of the 6-pack
Multi-function Displace (MFD), map systems readings
What three instruments are still present in the cockpit and why?
ASI, VSI, and altitude indicator in case there is an electrical failure
What are the 3 axes of the airplane, what surface controls the motion and what motion is the result?
Lateral axis: Elevator, pitch
Longitudinal axis: Aileron, roll
Vertical axis: Rudder, yaw
What motion does the vertical axis control?
Yaw by using the rudder
What motion does the lateral axis control?
Pitch by using the elevator
What motion does the longitudinal axis control?
Roll by using the aileron
By using the ailerons what axis is used and happens to the aircraft?
The aircraft will roll (left/right) on the longitudinal axis
By using the rudder what axis is used and happens to the aircraft?
The aircraft will yaw (left/right) on the vertical axis
By using the elevator what axis is used and happens to the aircraft?
The aircraft will pitch (up/down) on the lateral axis
What are the primary control surfaces
Ailerons, control the aircraft to roll left or right
Elevator, controls the aircraft climb and descend
Rudder, controls the aircraft to yaw to the left or right
What are the secondary flight control surfaces?
Flaps, increase lift when flying at lower airspeeds
Trim, decreases the pressure required to maintain the controls
What is the main benefit of flaps?
Allow steeper approaches without reducing airspeed
