Type Rating
I am sure that some of the experts on the forum will correct me if I am wrong but my nderstanding is that once you have your licence PPl/CPL to add a new type you must complete 5 hours of training on type followed by a flight test. To maintain the type on your licence you then need a minimum of 2 hours on that type during the year and you do an annual LPC or licence Proficiency Check. I beleive that the time taken for the LPC can be included in the 2 hours.
Gets expensive if you have a lot of types on your licence!
