Whopity you're missing the point. I don't give a flying f*** whether the student does a HASELL check. What I do do is make sure that the exercise I'm about to complete can be done safely - TEM. Indeed, in your second paragraph you've indicated that you do TEM before commencing an initial steep turn exercise (you mention a safe height - i.e. not 500ft). Do you really launch into an instructional steep turn without having a good look (i.e. not just standard lookout)? If you do, what county do you frequent?
Centaurus, go and do an intentional stall in you 737 for real without doing a HASELL check (or equivalent) and you will be fired.
