 Navigation is the 'ART' of determining the
position of an aircraft over earth's surface
and guiding its progress from one place to
another.
 To accomplish this ART, some sort of ‘AIDS'
are required by the PILOTS.

 NDB: Non Directional Beacon
 VOR: VHF Omni Range
 DME: Distance Measuring Equipment
 ILS: Instrument Landing System
 Satellite Navigation

 DME is stand for Distance Measuring
Equipment.
 DME is a type of en-route navigation system
for aircraft.
 DME often installed near VOR stations so as
to provide combined bearing and distance.
 When DME is installed with the VOR, it is
referred to as a VOR/DME.

 DME enables aircraft to establish its range to the
ground station: Distance in nautical miles, Ground
speed in knots, Flying time to the station in minutes

CRITICAL AREA
is an area of defined dimensions
about the LOCALIZER and GLIDE PATH
where
vehicles, including aircraft,
and any obstructions
(e.g. buildings, fences, trees, etc.)
will cause unacceptable disturbances
to the
ILS performance.

SENSITIVE AREA
is an area extending beyond
the critical area where the
parking and/or movement of
vehicles, including aircraft,
and the
presence of buildings, trees, fences, etc.
may affect the
ILS performance.

 Calibration is the validation of signals
transmitted by an equipment.
 VOR, ILS, NDB, DME are different navigation
aids that need periodic flight inspection.

Aircraft equipped with special and dedicated
hardware (called Flight Inspection System)
collect radio-navigation aids’ data and apply
(compare with) international standards’ tolerance
to validate electronic signal in space and certify
final status of aids.

The goal is having a safe air navigation
infrastructure, ensuring the integrity of
instrument approaches and airway
procedures.

Area Navigational aids
•DVOR (DPN)
•DVOR (DIG)
•DME (HP) Co-located with DVOR’s
Terminal Navigational Aids
•ILS (27)
•ILS (09)
•ILS (28)
•ILS (10)
•ILS (29)
•ILS (11)
•DME (LP) Co-located with GP
•GBAS (PROPOSED)
Some Nav-Aids like NDBs, Markers, Locators and Sat VOR’s
(CHI, SAM and SKA) are located outside the Airfield.
