32
Q

FADEC

A

full authority digital engine control

33
Q

navigation systems

A

assist the pilot by providing position and orientation information relative to the ground

34
Q

main navigation systems

A

air traffic control, instrument landing systems, navigation displays, global positioning systems

35
Q

sections of ATC

A

ground and tower control, approach control, en-route control

36
Q

control zones

A

area extending from ground level to 2000/3000ft

37
Q

control classes

A

area extending from 2000/3000ft upwards

38
Q

ATC

A

regulates air traffic through decision of segments and airspace

39
Q

purpose of ILS

A

a beam based system for guiding aircraft towards touchdown

40
Q

components of ILS

A

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
Q

localiser beam of ILS

A

represents the horizontal limits for the decent of the aircraft, transmitted from the end of the runway

42
Q

guide slope beam of ILS

A

represents the vertical limits for the aircraft to follow to reach the runway, transmitted from the beginning of the runway

43
Q

outer marker

A

positioned 6.5 miles from runway

44
Q

middle marker

A

positioned 0.6 miles from runway

45
Q

attitude director indicator

A

provides roll and pitch information and command suggestions for the pilot through the command bars

46
Q

horizontal situation indicator

A

provides course information about the aircraft

47
Q

beacon based navigation

A

uses electronic transmitting beacons to determine relative position and course of an aircraft

48
Q

VOR beacon system

A

very high frequency omnidirectional range beacons system (common)

49
Q

engine management system

A

ensures safe operation of the engine via the engine flight control system and monitors the fuel and air bleed from the engine

50
Q

flight performance management system

A

manages the flight profile, selects flight routes and navigation beacons, ensures the flight procedures are adhered to and records flight data

51
Q

utilities management system

A

monitors and controls fuel, hydraulics, environmental and electrical supplies, also regulates weight disteubution

52
Q

health and usage management system

A

ensures all systems, sensors, and actuators are operating correctly, in case of a failure it warns the pilot and can provide assistance

53
Q

weapons management system

A

ensures the carriage of weapons is safe for the pilot and surroundings and ensures the weapon release systems are operating correctly

54
Q

communication systems

A

provide all radio links between the aircraft, other air users, and ground based systems

55
Q

frequency bands

A

VLF, MF, HF, VHF, UHF

56
Q

VLF

A

very low frequencies- 3 to 30kHz (submerged submarines)

57
Q

MF

A

medium frequencies- 200 to 16000kHz (non directional navigation beacons)

58
Q

HF

A

high frequencies- 2 to 30MHz (long range communications)

59
Q

VHF

A

very high frequencies- 100 to 200MHz (air traffic control)

60
Q

UHF

A

ultra high frequencies- 200 to 400MHz (military navigation)
