This won`t be the first issue with Mahan Air as a few weeks back at Manchester when 24L was in use during runway repairs one was told to go around because he was well north of track during and VOR approach and on his second was was if anything worse and a lot lower making a huge track correction at about 3 miles out and I would estimate a good 300ft below glide path
I live at about 4 miles on the approach and have never seen anything as low as it was
Any comments from MAN ATC
Please note these are only my estimates but it did concern me at the time
