Programme of substitution, installation and
removal of AN radio-aids
ILS/DME (Instrument Landing System / Distance
Measurement Equipment) The ILS provides aircraft
with guidance information so that pilots, without
external visual references, can reach a point
of the descent path situated at a height called decision
height, Once this height has been reached and
only if pilots have established visual references with
the runway, they will continue the descent and proceed
to land.
Activities:
Substitution of the ILS of Saragossa Airport,
runway 30R.
Relocation of the LOC subsystem of Pamplona Airport
due to the runway extension.
Relocation of the GP-DME subsystem of runway
20 at Gerona Airport, because the threshold was
set back to adapt the ILS system for category III
operations.
VOR-DME (VHF Omnidirectional Range-Distance
Measurement Equipment) The VOR equipment
supplies guidance information about the radius in
which the receiver is located with respect to a direction
of reference that is generally the magnetic north
of the VOR station, The DME equipment provides aircraft
with continuous and precise indications of the
oblique distance between it and the ground-based
station.
Activities:
Installation of a DVOR/DME in Cuesta de la Reina
(Malaga) to substitute for the existing VOR-DME.
Installation of the new DVOR-DME “LTE” in Lanzarote.
General information
Air navigation
NDB (Non Directional Beacon) This device permits
pilots to select a heading and follow it, both en-route
and during non-precision approaches or instrumental
departures.
Activities:
Substitution for the NDB of Pamplona “PP”.
Relocation of the NDB of Vigo “VI”.
Programme to conduct studies of radioelectric
servitudes and simulation
The main tasks carried out within this programme are
289 studies of simulation and radioelectric servitudes,
Of these, 281 resulted from requests by the DGAC and/
or the DPI and the rest (8) were internal requirements
of the DNV or requests made directly to the division basically
related to the critical or sensitive areas of the ILS
systems.
2, SURVEILLANCE
Surveillance is defi ned as the technique of the timely
detection of targets, the determination of their position
and the delivery of this information to users to support
the safe separation and control of targets within a defi -
ned area of interest, The main activities carried out during
2009 were:
Radar Surveillance
New MSSR station between the parallel runways
18-36 of Madrid-Barajas Airport.
Provisional MSSR in Valencia.
Updating the Valencia radar station (PSR+ MSSR).
Surface Surveillance
Completion of the installation of the mode S multilateration
system for Tenerife-Norte Airport.
