An aerobatic maneouver is something over 30 degrees of bank according to the FAA
Fine, but most of us on this forum do not live in FAA land and I would not apply their standards just for the sake of it.
There was a steep turn article in "Loop" magazine last month and the writer there says your instructor
may want you to do HASELL checks, I think that is how it should be left, it is up to the CFI of any particular school to decide the school standards (not done as much as it should), they will normally know the local examiners anyway. Most schools that I know do not teach HASELL before steep turns and no examiner that I know requires it, but I have no problem with any that do.
