hello chaps,
the southerly has some work in progress (as of 2 weeks ago) and the northern only got an ndb app from one direction/ full ils from the other. the vor/dme associated with that ndb is u/s.
so i guess if u were tired and got a late switch to the ndb on the right and were a bit off centre (+-5),it may even be offset by a couple, and got a late vis at decision u could just possibly **** it up and land on a taxi way. anybody who been in and out of gru in dodgy weather will testify that it can get a little bit like hard work flying that ndb procedure coming in from the nw.
unforgivable but possible.
