Has anyone ever captured a false glideslope
Manila circa 1985 in a 737. . Radar vectored high and discovered perfectly flyable glide slope of about 5-6 degrees. Picked the problem by comparing DME v Height. While descending at idle thrust at 8 miles out we were showing very slightly above this glide slope on the ILS. Reported it after landing and the Manila CAA did a flight test and confirmed the presence of this steep glide slope. Error in ground maintenance. A few months earlier an Air Manila (?) B707 crashed just short of the same runway while descending CAVOK. The captain swore he was on glide slope - which no doubt he was, except it was the flyable false one. Been like that for ages apparently and no aircraft had reported it. The 707 had descended with full flap and idle thrust with high rate of descent to remain on GS. Despite this the captain elected not to go-around as he said he thought the noise of the engines spooling up would likely frighten the passengers. Maybe he thought a crash landing would be less scary?
