for my cpl training my instructor has asked me to list all the considerations
As you are undergoing CPL
Training Your instructor should be teaching you all the considerations required of the task. By teaching rather than making you fumble and stumble, you will then be able to discuss each consideration with him. Maybe the instructor is short on knowledge himself
he told me to think more commercially
Same instructor problem all over again. Sounds like he is too lazy to teach you. You are paying him a lot of money to teach you how to "think more commercially" How can you be expected to be an expert on commercial matters when he hasn't taught you in the first place?
