To become a class 1 load pilot, you need to be a class 2 (lower grade) pilot and meet the experience criteria. 

To meet the criteria, this includes the class 2 pilot working behind (second pilot position) on at least 25 occasions. 

These 25 loads must be documented and signed off by the class 1 pilot using this form:
