So, the procedure is to fly to the VOR, down the length of the runway then round the 'racetrack' to make a curving right hand to final as Pilotboyy said earlier. I guess the heights are in metres?? (my French is 'merde')
So, the question is - why did they come down in the water so far north of the island. Wrong QNH/QFE?
The MVI Rwy 20 approach is to turn left over HA, which is roughly 4 NM south of threshold 02. Then enter a right downwind until Radial 308. Then turn in inside the obstacle lights (feux a eclats). The approach charts calls for "to have the lights always to the left of the airplane." Intercepting the final is about 2NM from threshold 20. It is a bit like Funchal, maybe not that tight.
The entire procedure is within a few miles of the airport and far off from the north coast, where the wreckage was supposedly located.
