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 identifica-

tion that are observed entering a SIDA may be 
reported to the Transportation Security Administra-
tion (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.
