SAGA System for Helicopter Takeoff, Approach and Landing
Hunan Chendong Technology Co.,LTD (shorted as CDT)is a professional manufacturer for Green navigational aids products, mainly for aviation obstruction lights, helipad lightings and meteorological target lamp in China . CDT got ISO 9001:2008 certification the first year when established.As pioneer in China, our products are approved by ICAO and CAAC certificate. CDT keep acting as a solution provider for customers with specialty. And our products have been exported over 50 countries and areas all over the world.
- Introduction
Approach Azimuth Guidance. The SAGA (System of Azimuth Guidance for Approach) provides a combined signal of approach azimuth guidance and threshold identification.
- Product Picture
- Specification
- The System of Azimuth Guidance for Approach will comply with ICAO recommendations Annex 14,Volume I paragraph 5.3.4 and French STAC.
- It will comprise of 2 “Flashing” Units (master and slave) located symmetrically on both sides of the
runway (or TLOF for heliport) threshold - Depending of his position on the approach axis, the pilot will receive visual information of two
“Flashes” supplied by the two “flashing” units of the SAGA. - If the pilot is on the axis +/- 0.45°, the two “Flashes”are simultaneous.
- If the 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. - The SAGA system will be powered in 110Vac-230Vac 50/60 Hz. It will be equipped with12 Vac 105 W pre-focused reflector lamps.
- It will be remotely controlled in 48Vdc.
- Monitoring will be possible through 2 dedicated dry contacts.
- The SAGA system will be available with heating resistors for cold and/or wet areas.
- The system will be automatically put out of service if at least one of its two “Flashing”
Units becomes defective. - The Body, Cap and Support of the “Flashing” Unit will be in aluminium alloy, phosphate and
painted in aviation yellow. All fixings and fastenings will be stainless steel. - The Power Supply Box will be made of reinforced polyester and will be IP 65 rated.
- The Legs of the “Flashing Units” will be frangible.
- Location on the field
The two light units of a SAGA system must be installed at 10 metres from the runway 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).The Master unit must be installed on the right of the Threshold
- 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 unidirectional rotating beams which give a flashing effect. The pilot receives, each second illumination of two “Flashes” provided in sequence with the two light units.
1. When the aircraft flies inside a 9° width angular sector, cen tred on the approach axis, the pilot sees the two lights “flashing” simultaneously.
2. 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 theaxis.
3. The visual signal is not visible when the aircraft flies outside the 30° angularsector.
