The SAGA system includes two light units (one Master and one Slave) placed symmetrically on both sides of the Runway (or TLOF) threshold supplying unidirectional rotating beams which give a flashing effect.The pilot receives, each second illumination of two “Flashes” provided in sequence bythe two light units.
• When the aircraft flies inside a 9° width angular sector, centred on the approachaxis, 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 the aircraft in the sector.
The further the aircraft is from the axis, the greater the delay. The delay between the two “flashes” produces a sequence effect which shows the direction of the axis.
• The visual signal is not visible when the aircraft flies outside the 30° angular sector.
The heliport SAGA system includes two light units placed symmetrically on both sides of the Runway threshold

Product Details
Location of the field
1.The two light units of a SAGA system must be installed at 10 metres from the runway.
2.Edge symmetrically on both sides of the Runway threshold (for TLOF the two units must be installed as close as possible to the threshold edges).
3.The Master unit must be installed on the right of the Threshold and the Slave unit on the left.
Design
1. SAGA optical head
2. SAGA power supply box
3. Frangible leg
4. Power supply box
fixation bars (x 2)
5. Power supply box fixing
screws (x 4)

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.
Mecanical Installation
Mechanical fixing of the SAGA light unit can be done in two ways:
1. On a hard surface (such as a concrete platform) using four sealing rods sealed in the concrete.The four sealing rods must be installed in square(sides = 200 mm).
2. On a surface which is not hard (such as earth) by using the four sealing rods delivered with the system. In this case, fixing is made on a concrete block (recommended standard sizes400 x 400 x 700 mm). The rods (M18 –400mm) must be sealed in the block making a 200 mm side square (the holes in the base plate have diameters of 22 mm).
Note: Adjustment of the optical head azimuth angle and to the horizontal is made using an aiming tool. The two SAGA units are delivered assembled and wired (connections power supply box / optical head).
Dimensions
Total height: 835 mm.
Optical head height: 335 mm, diameter = 254 mm.
Power supply box: 400 x 300x 160 mm.
Frangible leg height: 500 mm, base plate = 250 x 250 mm.
Electrical Cabling.
The SAGA System is comprised of two light units, one Master (A) and one Slave (B) linked together by electrical wiring. The figure below shows all the electrical connections of a complete SAGA system, connections between lights units + connection with the main supply distribution panel (C)+ connection with control and monitoring desk (D) + connection between power supply box (E) and optical head (F).(Reference the following picture)

SPECIFICATION
* Itwill comprise of 2 “Flashing” Units (master and slave) located symmetrically on both sides of the runway (or TLOF for heliport) threshold.
* Dependingof his position on the approach axis, the pilot will receive visual information of two “Flashes” supplied by the two “flashing” units of the SAGA.
* Ifthe pilot is on the axis +/- 0.45°, the two “Flashes” are simultaneous.
* Ifthe pilot is not on the axis within an angle comprise between -30 and +30°, The two “Flashes” will be see delayed of a time between 60 and 330 ms (the further the aircraft is from the axis, the greater the delay). The delay between the two “flashes” produces a sequence effect which shows the direction of the axis.
