Final answer:
To access an airport SIDA, one must have an airport-issued or approved ID. TSA screening is for passengers, and an FAA pilot certificate is separate from SIDA access requirements.
Step-by-step explanation:
To enter an airport's Security Identification Display Area (SIDA), you must have an airport-issued or approved ID. While passing the TSA screening is a prerequisite for passengers to board flights, workers and other personnel with a need to access secured areas of the airport must have proper identification that typically includes an airport-issued badge with a current, authorized access area clearly displayed. An FAA-issued pilot certificate may be required for those operating aircraft, but by itself, does not grant SIDA access without the designation on an approved ID.
