EGPH 06 ILS
The current NOTAM for the 06 ILS at Edinburgh is:
RWY 06 ILS GP MAY NOT MAINTAIN FULL SCALE FLY UP INDICATIONS WHEN LEFT OF THE LOCALISER CENTERLINE AND BELOW GLIDEPATH
My reading of that is that if left of the localiser and radically below the glide path, the ILS may be erroneous. But does that mean that the ILS is still reliable if only marginally below the glide path?
Anybody know what might be the cause of this anomaly?
