Altitude: 975 ft
Speed: 157 kt
Heading: 201°

No mention anywhere of the prevailing QNH, so no way of telling what adjustment the transponder data needs in order to produce an accurate height AMSL or AGL, or whether that was done by AH.

975 feet minus field elevation of 593 gives 382 feet above the field at what I measure to be about 7 nm to the runway threshold. QNH is 1015 hPa so the correction is small (~50 feet?) and we don't know the local elevation where they were but it doesn't look like a valley to me.

So, 400 feet, 600 feet or 300 feet, it's nowhere an A380 should be on approach that far out.

On the first pass it appears that they never intercepted the centerline for 14R and continued on about a 190 heading for the go around. On the second approach they seemed to make a level pass at approach speed at a FR24 indicated altitude of 2550 feet after overshooting final slightly and then paralleling the extended runway centerline slightly to the left. The third approach appears normal with a dogleg intercept to final and an appropriate descent.
