15.  Security Identification Display Area (SIDA) 

a. 

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. 

b. 

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
