Interpretation

The ILS runway 04 glide path may experience signal fluctuations at distances of 5 NM or greater, possibly due to terrain within its reflection area. Nuuk Airport is investigating the cause and requests pilots using the ILS runway 04 to report the distance from the aerodrome, duration, nature, extent and operational effect of any fluctuations.
