Wingover - caution
A wingover is exactly as described by 2d - but do be careful, low level w/o's have bitten their fair share of tyro's! They have also bitten a few "experienced" folk - RAF Nimrod in Canada a few years ago.
It is really imperative that one watches the angle of bank as one approaches the "halfway point" - at this point ideally you'd want to be positive approaching knife edge, NOT negative!
Was very surprised to see the maneouver in the BAeA (beginner/std)) sequence a year or two ago.
