Hey Mate
The course she speaks about is the Ground course for the 32. It is intense as it use to be over 8 or so days but is now compacted into 5-6.
Yes you are right and wrong. They are not a "scheduled airline" they operate as a charter company with one of their clients being AIR NZ. This is common knowledge and they are often filling in for the 1900s when they are in for heavy maintenance. Being a charter outfit they are going to get a variety of customers requesting different services and so you will quite often see the jets at skycare performing charter or medivac work.
Again from what I hear, the variety is great and so are the people.
The decision is yours and good luck with it.
