I always taught it. Don't see the point of spending hours and hours dragging a heavily protesting aircraft to a stall - from which it will probably recover itself if left alone - whilst not spending 10 minutes looking at spiral dive recovery.
Spiral dives kill, they are scary and they are commonly encountered by low time pilots feeling their feet. In the traditional circling their house they are - in my opinion - 10 times more likely to end up in a spiral dive than in a stall.
For a switched on Bloggs at PPL level they get to do it on instruments and it was a common feature of PPL checkout/annual refresher flights.
An area of the syllabus that perhaps the CAA need to look at again?
