The other issue that concerns me is the Handling sim that was introduced to improve our handling skills {DUH} is being hijacked to cover niff naff such as cargo fires, low temp altimetry, and other minor topics that can all be covered in regulatory items in PC/RT sessions . I would suggest we would be better off practising hand flying visual approaches and other back to basic skills in the Handling session.
Be careful what you wish for........
You may remember when the handling sim began a few years ago, it was close to what you suggest (not quite, but close), and it was constantly being used as a "free reserve" by screw control. So, one of the designers of the program very cleverly added in a few CAD required recurrent items, that was it can't constantly be changed. A small smattering of the "niff naff" as you call it is a small price to pay to ensure that the session is actually completed, IMHO.
