Big Pistons Forever is absolutly right, in Canada spining has been dropped from the PPL course, but it remains a 'flight test item' for the CPL.
Personaly I enjoy spinning and think it is an essensial tool for building good hands and feet skills, as well as confidence.....but only if done safely.
Having said that, I have only practiced spinning in a C172 which is extreamly docile in this area compared with other machines. I once had the oppertunity to fly some 'areos' in an Extra 300, talk about spinning.........!!! Deffinately a case of 'don't try this at home kids'. No, I wasn't on my own; and yes, the back seat had an extreamy proficient and well experienced aerobatic pilot sat in it. I didn't think the world could wizz around that fast...what a ride !!!
