Air Law is the subject that will tell you what you can and cannot do. Most of the Air Law segment is common sense - you basically have to demonstrate good airmanship. But, procedures and regulations are there for a reason - and you have to prove that you understand them.
This book covers in full the EASA learning objectives for the Air Law subject for CB-IR and the BIR. And as a digital book it will be updated as often as necessary, as well as improved based on the readers feedback.
