Visual Signals

Photometric Measurement of Rubh Cadail (NLB)

The Visual Signalling section within R&RNAV undertakes various projects, research studies and provides engineering support to GLA operations.

Research studies include investigations into how the human visual system responds to a flashing light, the development of new light sources and visual conspicuity.

Engineering support includes the photometric and colorimetric measurement of aid-to-navigation lights, this may be conducted within one of our two light ranges, however field measurements are also conducted where appropriate.
