What is an aircraft type rating, and which aircraft require one?

A type rating authorises a pilot or to operate a particular type of aircraft. All aircraft that are certified for multi-crew operations will have a type rating. Type ratings are also given to specified single-pilot aeroplanes that have performance, complexity or handling characteristics that warrant pilots completing a type specific training course.
In order to pilot a type-rated aircraft, you need to complete the relevant aircraft type training and flight tests. At the end of the test, assuming you pass, your flight examiner will enter details of the rating in your licence and send a report to CASA so that your records can be updated.
