Product Overview
The ALS Heliport Visual Alignment Guidance System provides a combined signal of approach by using angles of azimuth guidance and threshold identification.
It comprises of 2 parts that are both flashing Units (one master and one slave) that work together to guide the pilot.
The system is located symmetrically on both sides of the runway (or TLOF for heliport threshold). Depending on the position of the aircraft on the approach axis, the pilot will receive visual information of two “Flashes” supplied by the two “flashing” units of the system. This indicates to the pilot if he is correctly “centred” or if the aircraft is too far left or too far right and to allow the pilot to adjust before landing.
Features & Benefits
