What is an aerodrome manager?

Could you please elaborate on the role and responsibilities of an aerodrome manager? I understand that they oversee the day-to-day operations of an airport, but I'm curious about the specific tasks they handle, the qualifications they need, and how their work impacts the overall efficiency and safety of an aerodrome. Additionally, how do they collaborate with other stakeholders, such as airlines, regulatory bodies, and emergency services? I'm interested in understanding the intricacies of this important position within the aviation industry.
