Directorate General of Civil Aviation (DGCA) Practice Test

Restricted areas are published under the special use airspace information in the AIP. In the ENR (En Route) portion, the subsection that lists restricted areas is ENR 5.1. This part provides the identifiers, geographic boundaries, vertical limits, and active times for each restricted area, along with any access requirements. Pilots consult this section when planning flights to avoid entering restricted airspace and to know when and where permission is needed. Other ENR subsections cover different topics, but they don’t specifically enumerate restricted areas, making ENR 5.1 the correct source.
