thanks guys for your advices!
It's quite hard, because I need to know news procedures, and I did not know the aircraft very well.
yes, we need to follow the standard training, I have got a syllabus, and standard procedures. So it's quite hard at the beginning because I need to read a lot of things, if you do not read carefully, you do not know the procedure well...
I have got 4 students, so 4 flights one after one, it's a little bit tiring...
