What is the first step to enter an ILS Critical Area?

The appropriate first step to enter an ILS Critical Area is to contact Airport Operations for authorization. This procedure is critical because ILS (Instrument Landing System) Critical Areas are designated zones where aircraft operations might interfere with the functioning of the ILS system, which is vital for pilots during landing approaches, especially in low visibility conditions.

By contacting Airport Operations, you ensure that the necessary checks and protocols are followed, safeguarding the integrity of the airport's operations and ensuring safety for all. This communication allows you to receive permission and any specific instructions needed before entering such an area, which is essential for maintaining operational safety and efficiency.

While informing your team about the entry, awaiting ATC clearance, or driving through without notification may seem reasonable in different contexts, they would not ensure the same level of safety and compliance with airport regulations as directly obtaining authorization from Airport Operations.
