To be able to complete your CPL / IR you must have a valid PPL and night rating, have 200 flight hours, undergo dedicated ground school for the theoretical subjects, and pass 10 examinations. You will also have to obtain a Class I aviation medical certificate and complete a flight test with a Designated Flight Examiner at the end of your course.
During the training towards your CPL / IR you may consider incorporating a Multi-engine class rating. This will ensure that you are a well-rounded pilot upon obtaining your CPL / IR ready to be employed.
A Multi-engine Class rating enables you to fly aircraft with two engines; this training is normally done towards the end of your CPL training, but can be done with only a PPL as well.
This course consists of ground lectures and 7 hours flight training in a multi-engine aircraft, followed by a test with a Designated Examiner. To be able to do a ME Class Rating, you need to have a minimum of 70hrs PIC time.
Differences and familiarization training will be required if you want to fly a different aircraft type or want to learn new or advanced systems on aircraft, such as aircraft fitted with variable pitch propellers and retractable gear.
