Question of aborted landing after instrument approach

The instrument approach provides terrain clearance along and
to a limited area either side of the final and missed
approach path charted. A climb along the approach path is
safe, but if you begin a turn prior to the charted location,
you run the risk of hitting an obstruction.
Consider a fictional IAP with a missed approach that calls
for a right turn and going direct to a fix. If it is an
ILS, the miss will start at 200 feet or lower from over the
runway. But if you miss on the three mile final and start
the turn (and climb) early, you would be about 700 at the
start, but could also be abeam a TV tower.

Perhaps most missed approaches can be flown differently, but
flown to the design, on the track that was flight tested, it
will work on any approach.

The only time an early turn will assure obstacle clearance is where the
missed approach track returns to the final approach fix or facility,
such as the LOM or where a VOR station is the FAF.
