Steep turns
Keygrip
Although I understand the point that you make I don't see the evidence. You qoute (paraphrasing) form the FAA syllabus but does it say steep turns are to be flown on instruments?
A steep turn can be used for collision avoidance, true. In my experience many pilots all too readily use angles of bank in excess of 30 degrees for many reasons. The ability to undertake a steep turn correctly and therefore safely is an important skill.
They may need to use such a technique while undertaking a forced landing, although descending the rate of descent will need to be managed using the skills learned.
