Interpretation

Qatar AIP for OTHH is amended to note that arriving aircraft may experience ILS glide path signal fluctuations on approaches to RWY 16R/34L due to taxiing and departing aircraft, and pilots should anticipate possible interference and closely monitor ILS profile, flight display indications, and autopilot behavior during manual or coupled ILS approaches.
