Question 210-35 : One of the possible disturbances of the ils signal is 'scalloping'..which statement is correct ?
Scalloping causes rapid indicator changes from side to side of the intended approach path which can not be followed by the aircraft.
.normally the ils signal gives you a 'straight line' down to the threshold. you may experience some interference with this signal, resulting in a 'bent' signal. if you follow the localiser/glideslope indications the path follows a sine curve all the way down to the runway. thus it oscillates above and below the normal slope. this oscillation is irregular and can not be followed by the aircraft.
