6 basic motions that are controlled during flight
heading, roll, banking, pitch, altitude, propulsion
26
heading control
motion- heading angle pilot input- pedals actuator- rudder on tail sensor- yaw gyroscope
27
roll control
motion- roll angle pilot input- lateral stick actuator- ailerons on wings sensor- roll gyroscope
28
banging control
motion- roll and heading angle pilot input- lateral stick actuator- ailerons on wings sensor- roll and heading gyros
29
pitch control
motion- pitch angles pilot input- longitudinal stick actuator- elevators on tail sensor- pitch gyroscope
30
altitude control
motion- altitude control pilot input- longitudinal stick and throttle actuator- elevators on tail and engine sensor- altimeter
31
propulsion control
motion- propulsion control pilot input- throttle actuator- engine sensor- accelerometer
32
FADEC
full authority digital engine control
33
navigation systems
assist the pilot by providing position and orientation information relative to the ground
34
main navigation systems
air traffic control, instrument landing systems, navigation displays, global positioning systems
35
sections of ATC
ground and tower control, approach control, en-route control
36
control zones
area extending from ground level to 2000/3000ft
37
control classes
area extending from 2000/3000ft upwards
38
ATC
regulates air traffic through decision of segments and airspace
39
purpose of ILS
a beam based system for guiding aircraft towards touchdown
40
components of ILS
localiser beam and guide slope beam. resulting corridor is the operation guide path for reaching the runway safely. 2 beacons: outer and middle marker
41
localiser beam of ILS
represents the horizontal limits for the decent of the aircraft, transmitted from the end of the runway
42
guide slope beam of ILS
represents the vertical limits for the aircraft to follow to reach the runway, transmitted from the beginning of the runway
43
outer marker
positioned 6.5 miles from runway
44
middle marker
positioned 0.6 miles from runway
45
attitude director indicator
provides roll and pitch information and command suggestions for the pilot through the command bars
46
horizontal situation indicator
provides course information about the aircraft
47
beacon based navigation
uses electronic transmitting beacons to determine relative position and course of an aircraft
48
VOR beacon system
very high frequency omnidirectional range beacons system (common)
49
engine management system
ensures safe operation of the engine via the engine flight control system and monitors the fuel and air bleed from the engine
50
flight performance management system
manages the flight profile, selects flight routes and navigation beacons, ensures the flight procedures are adhered to and records flight data
51
utilities management system
monitors and controls fuel, hydraulics, environmental and electrical supplies, also regulates weight disteubution
52
health and usage management system
ensures all systems, sensors, and actuators are operating correctly, in case of a failure it warns the pilot and can provide assistance
53
weapons management system
ensures the carriage of weapons is safe for the pilot and surroundings and ensures the weapon release systems are operating correctly
54
communication systems
provide all radio links between the aircraft, other air users, and ground based systems
55
frequency bands
VLF, MF, HF, VHF, UHF
56
VLF
very low frequencies- 3 to 30kHz (submerged submarines)
57
MF
medium frequencies- 200 to 16000kHz (non directional navigation beacons)
58
HF
high frequencies- 2 to 30MHz (long range communications)
59
VHF
very high frequencies- 100 to 200MHz (air traffic control)
60
UHF
ultra high frequencies- 200 to 400MHz (military navigation)
