Whopity, the EASA definition of 'aerobatic flight' has now been amended after the Kölunatics had the problems of their original definiton pointed out to them!
The latest definition is:
“...an intentional manoeuvre involving an abrupt change in an aircraft’s attitude, an abnormal attitude, or abnormal acceleration, not necessary for normal flight or for instruction for licences or ratings other than the aerobatic rating.”
As usual it has been drafted in tortuous €urospeak, with far too many commas. But at least it means that Instructors won't need Aerobatic Ratings to teach stalling, spinning (e.g. for FI candidates), IF UPs, steep turns etc.
As for a pilot being 'legally entitled' to teach IF without holding any qualifications, the unqualified being taught by the equally unqualified will simply mean that acquired bad habits will have to be eradicated by a proper instructor at some future juncture.
