Anyone here think that they can impart something other than knowledge to a student simply by talking to them.
Perhaps you think that PL would approve of a B737-300 pilot sitting in and having a chat for a while before being signed off to fly the B737-800 with a full load of pax. That may be your understanding of what is ment by "differences training" but it is not EASA or JAA or CAA or (insert any other authority name) opinion.
If all you do is impart knowledge then all you have done is familiarisation training.
Every good instructor remembers - brief, demonstrate, practice, debrief.
Where in your "differences Training" is the demonstrate or practice and how can you debrief a student on their performance if you have never seem them do anything?
Unless you have a sim, flying is the only option for diferences training.
I will take it all back when PL puts it in writing that differences training can be accomplished by simply doing a brief.
