In the last war,that is 39/45 the Germans told their pilots if they lost control in cloud to put the a/c into an intentional spin then recover from the known condition when in visual contact with tera firma, oops 500ft. cloudbase FW190 needs 1500ft. to recover from spin is this relevant, no but true. Unusual atts. a must lots and lots of them and lots of spinning especially with full power on. After all most aeros require a generous power setting.Spinning or at least the entry with no power on if aero training is not giving the student the best insight as to what might go wrong.Lots of altitude, if all else fails lock controls firmly, to prevent structional damage, till flight condition recognised then recover. OR GET OUT IF YOU HAVE SOME SILK.!Oh yes beware of the instructor who wants to show you his sequence you will feel ill and he will have fun and you are paying1
