Heliport Approach Azimuth Guidance ,System of Azimuth Guidance for Approach halogen reflector lamp AC110V 220V ICAO SAGA lights
Product Description
Operation principle
The SAGA system includes two light units (one Master and one Slave) placed symmetrically on both sides of the Runway (or TLOF) threshold supplying unidirectionalrotating beams which give a flashing effect.
The pilot receives, each second illumination of two “Flashes” provided in sequence bythetwo light units.
• When the aircraft flies inside a 9° width angular sector, centred on the approach
axis, the pilot sees the two lights “flashing” simultaneously.
• When the aircraft flies inside a 30° width angular sector, centred on the approach axis and outside the previous one, the pilot sees the two lights “flashing” with a variable delay (60 to 330 ms) according to the position of theaircraft in the sector. The further the aircraft is from the axis, the greater thedelay. The delay between the two “flashes” produces a sequence effect which showsthe direction of the axis.
• The visual signal is not visible when the aircraft flies outside the 30° angular sector
Location on the field
The two light units of a SAGA system must be installed at 10 metres from therunwayEdge symmetrically on both sides of the Runway threshold (for TLOF thetwo unitsmust be installed as close as possible to the threshold edges).
The Master unit must be installed on the right of the Threshold and the Slave unit on the left.

Main Advantages.
• Safe operation: The SAGA system is automatically stopped when at least one of its light units is out of service. A signal is available for monitoring of this default status in the control room.
• Easy maintenance: Very easy access to the lamp and all terminals. No special tools are required.
• Brilliancy levels: The remote control of three brilliancy levels is possible for a better visual comfort for the pilot (no dazzling).
• Efficiency: Coupled with a PAPI, the SAGA system supplies the pilot with the security and the comfort of an Optical “ILS”.
• Climate: In order to maintain operation even in very cold and/or wet areas, the light units of SAGA are equipped with heating resistors.
• Additions of red filters (option) provide to the SAGA system with the option of emitting red Flashes corresponding to fly exclusion zone due to obstacles.
