Question 4

 Uses electronic interface
 The movements are converted to electronicsignals transmitted by wires.  Flight control computers determine howto moveeach control surface to provide the expectedresponse.  Automatically adjusts control surfaces to stabilizethe aircraft

Answer 4

Fly by Wire

Question 5

They are intended to:
1. i m p r o v e t h e a i r c r a ft p e r f o r ma ncecharacteristics
2. relieve excessive control

Answer 5

Secondary Flight Controls

Question 6

Subpart of secondary flight controls

Answer 6

High lift devices
Spoilers and speed brakes
trim tabs

Question 6

2 parts of high lift devices

Answer 6

Slats
Flaps

Question 7

• they are placed on the leading edge of
  the wings
• they increase lift during low speed
  operations such as takeoff, climb,
  approach, and landing.
• increase the surface area of the wing
• extends and retracts

Answer 7

Slats

Question 8

are the most common high-lift devices
used on aircraft.
– These surfaces, which are attached to the
trailing edge of the wing, increase both lift
and induced drag for any given AOA

Answer 8

Flaps

Question 9

types of flaps

Answer 9

Plain flap
Split flap
Slotted flap
fowler flap
slotted fowler flap

Question 9

Importance of Flaps

Answer 9

Shorter takeoff roll
slower landing speeds
steeper descent path
better view of the runway
decrease the stalling speed of the airplane

Question 10

parts of spoilers and speedbrakes

Answer 10

Outboard spoilers
Inboard Spoilers

Question 10

are secondary flight control surfaces that can be deployed manually bythe pilot or, under certain circumstances, that extend automatically. ———-are purely drag devices Spoilers simultaneously increase drag and reducelift.

Answer 10

Spoilers and Speed brakes

Question 10

• Reduces the stick forces or control force so that
  the pilot can maintain any yaw, pitch or roll without
  further control unit.

Answer 10

Trim tabs

Question 11

poormans auto pilot

Answer 11

Trim tabs

Question 12

• Is the natural quality of an aircraft to correct for
  conditions that may disturb its equilibrium, andreturn to or continue on the original flight path

Answer 12

Stability

Question 13

– Is the natural ability of an airplane to recover
from a disturbance in the yawing plane.
– Stability around the vertical axis

Answer 13

Directional Stability

Question 14

– Is the natural ability of the airplane to recover
from a disturbance in rolling without pilot input
– Stability around the longitudinal axis

Answer 14

Lateral Stability

Question 15

– Is the natural ability of the airplane to recover
from disturbance in pitching without pilot input
– Stability around the lateral axis

Answer 15

Longitudinal Stability

Question 16

 Is the result of the earths surface altering theairflow patterns about the airplane
 Phenomenon that reduces induced drag whentheairplane is within 1 wingspan of the ground
 Prominent on takeoffs and landing

Answer 16

Ground Effect

Question 17

Take off characteristics in ground effect

Answer 17

Aircraft may become airborne before the rotation speed
Might climb out and sink back to the ground

Question 18

Landing characteristics in ground effect

Answer 18

Causes the aircraft to float down the runway
Makes it difficult to sink

Question 19

primary flight control

Answer 19

aileron
rudder
elevator

Question 20

Back pressure

Answer 20

Elevator Up

Question 21

Forward pressure

Answer 21

Elevator down

Question 22

parts of empennage

Answer 22

Elevator
Rudder
Trim Tabs
Stabilizer

Question 23

increase or improve the lift of aircraft

Answer 23

High lift devices
