But than again after doing a dozen of this CRM sessions I would be happy to do a course on the internet just to comply with legal requirements.
And when flying with mixed nationals as crew why even bother with CRM as most crew do not understand each other. Level 4 English requirement was moved again.
Depends on what state we are dealing with regarding their CRMI training requirements. Some unscrupulous regulator could well approve an on line CRMI training program, but their attitude to the task could be viewed as nothing more than a 'tick box' exercise! Here in Europe, on line CRMI training will be unthinkable for some time and quite right too!
I find it totally unacceptable that that CRM should be overlooked just because you are operating with different nationalities! In fact that is even more reason for making an effort with CRM training for those crews!

Keep the jokes coming please!
IMHO, the more important aspects of CRM involve knowledge (human performance and technical issues / interaction), and the behavioural aspects associated with the use of that knowledge. The latter relates to awareness and decision making, and the judgement required to maintain safety. Many of these can be taught on line, although review and assessment will require special interaction.
Crew interaction and judgement skills can not be exercised in front of a PC. These are life skills and CRMI courses need a captive audience for the trainee to get the best out of the various presentations and discussions that are carried out at these courses. CRM is not a 'black and white' exercise and that is why an artificial environment such as being on line will not work for CRMI training!
