So Ara will have had a training document detailing the circumstances and outcome of his recurrent IIMC training then - yet for a real it went for a ball of chalk.
Yes. Plus the available record goes back several years.
Is there any mandated use of 3 or 4 axis AP systems in that IIMC recovery or is it all flown manfully without having to demonstrate proficiency with the kit in your aircraft?
If I recall the Island IIMC procedure included manual and AP recovery but not 100% sure. The link below will take you to the Docket which has the actual Island IIMC procedure, training records, and a bunch of other info which should answer your questions that are outside of my skill set.
