4.  The International Civil Aviation
Organization (ICAO), is a specialized
agency of the United Nations.
 The Air Navigation Commission (ANC) is the
technical body within ICAO.
 ICAO defines the protocols for air
accident investigation followed by transport
safety authorities in countries.

ILS Localizer

11.  Localizer (LOC) is the lateral component for the
runway centre line when combined with the
vertical glide slope.
 Localizer is made up antenna arrays.

12. ILS Localizer needle

13.  A glide slope station uses an antenna array sited to one side of
the runway touchdown zone.
 The centre of the glide slope signal is arranged to define a
glide path of approximately 3° above horizontal (ground
level). The beam is 1.4° deep (0.7° below the glide-path centre
and 0.7° above).

14. Glide slope Needle

15.  The Instrument Landing System (ILS) provides a means for
safe landing of aircraft at airports under conditions of low
ceilings and limited visibility.
 The use of the system materially reduces interruptions of
service at airports resulting from bad weather by allowing
operations to continue at lower weather minimums.
 The ILS also increases the traffic handling capacity of the
airport under all weather conditions.

16.  Distance measuring equipment (DME) is
a transponder-based radio navigation
technology that measures slant
range distance by timing the propagation
delay of VHF or UHF radio signals.
 A radio signal takes approximately 12.36
microseconds to travel 1 nautical
mile (1,852 m) to the target and back—also
referred to as a radar-mile.

17.  VOR is a type of short-range radio
navigation system for aircraft.
 Uses frequencies in the very high
frequency (VHF) band from 108 to
117.95 MHz.
 Aircraft contains 2 demodulators for
FM- Variable Phase
AM- Reference Phase
 Contains 49 antennas in rotation (48
variable antennas and 1 fix antenna in
middle).

18.  NDB GIVES THE RELATIVE BEARING.
NDB GIVES THE CLOCKWISE ANGLE BETWEEN
THE NOSE OF AN AIRCRAFT AND THE NDB.
IF I.L.S IS NOT WORKING THEN NDB CAN DO
THE TASK.
