AIM ¶ 2-3-15 — SIDA Security Areas
Learn AIM 2-3-15: Security Identification Display Areas (SIDA), badge requirements, AOA vs Secured Area, and TSA inspection rules every pilot must know.
In Plain English
Security Identification Display Areas (SIDA) are restricted zones at airports where access requires a badge issued under 49 CFR part 1542. Understanding SIDAs is critical because unauthorized entry can lead to civil and criminal penalties for both pilots and passengers.
Key distinctions:
- Air Operations Area (AOA): aircraft movement or parking areas — may or may not be a SIDA
- Secured Area: where commercial passengers enplane — always a SIDA
Operational points to remember:
- Movement into or through a SIDA requires both authorization and proper identification displayed
- Airports with SIDAs publish maps and descriptions showing boundaries — check with airport authority if unsure
- Unauthorized persons may be reported to TSA or airport security
- Pilots should brief passengers before arriving at unfamiliar airports
- Report suspicious activity via AOPA's Airport Watch Program: 866-427-3287
Under 49 CFR 1540, any holder of an airman certificate, medical certificate, authorization, or license issued by the FAA must present it for inspection when requested by TSA. This is a regulatory requirement, not just a recommendation — keep your certificates accessible whenever you fly.

FAA AIM ¶ 2-3-152-3-15. 2-3-15. Security Identification Display Area (SIDA)
Security Identification Display Areas (SIDA) are limited access areas that require a badge issued in accordance with procedures in 49 CFR part 1542. A SIDA can include the Air Operations Area (AOA), e.g., aircraft movement area or parking area, or a Secured Area, such as where commercial passengers enplane. The AOA may not be a SIDA, but a Secured Area is always a SIDA. Movement through or into a SIDA is prohibited without authorization and proper identification being displayed. If you are unsure of the location of a SIDA, contact the airport authority for additional information. Airports that have a SIDA will have a description and map detailing boundaries and pertinent features available. Pilots or passengers without proper identification that are observed entering a SIDA may be reported to the Transportation Security Administration (TSA) or airport security and may be subject to civil and criminal fines and prosecution. Pilots are advised to brief passengers accordingly. Report suspicious activity to the TSA by calling AOPA's Airport Watch Program, 866-427-3287. 49 CFR 1540 requires each individual who holds an airman certificate, medical certificate, authorization, or license issued by the FAA to present it for inspection upon a request from TSA.
