There used to be takeoff minimums where a turn was required as soon as

There are still a bunch of these in Alaska. Go to:

and then search for "immediate".

Those never did comply with TERPs criteria. TERPs did permit the use of the
word"practicable," not "immediate" for departures provided not less than
400-1 was also required. The FAA in Alaska marches to a different drummer.
