I recall back in 2000 taking the King 727 FE VHS Video course + Coursebooks (cannot reconnect a disconnected CSD in-flight etc) - oh happy days! It was pretty thorough course even though I was then preparing to undertake the CPL/IR. The 727 FE study helped with the 737 T/R systems course and never regretted taking it (even though I never became certified on the 727).
Would have loved to have been on the panel though.
