Number：CTSO-2C611 Date of approval：August 18, 2025 Approved by：Xu Feng China Civil Aviation Technical Standard Order This China Civil Aviation Technical Standard Order (CTSO) is issued according to Part 37 of the China Civil Aviation Regulations (CCAR-37). Each CTSO is a criterion which the concerned aeronautical materials, parts or appliances used on civil aircraft must comply with when it is presented for airworthiness certification. Airborne Aeronautical Data Processes and Associated Databases 1. Purpose. This China Civil Aviation Technical Standard Order (CTSO) is for manufacturers seeking airborne aeronautical data processes and associated databases CTSO authorization (CTSOA). This CTSO specifies the minimum performance standards that airborne aeronautical data processes and associated databases must meet for approval and identification with the applicable CTSO marking. 2. Applicability. a. Aeronautical data of this CTSO designate to data used for aeronautical applications such as navigation, flight planning, terrain awareness, and other purposes (e.g., navigation data, terrain and obstacle data, and airport mapping data). Other applications may include new and novel aeronautical applications (e.g., dynamic electronic charts, etc.), for which the data quality requirements and intended functions may require CAAC CTSO-2C611 - 2 - new policy development, or issue papers. Software programming pins (for selectable software option), configuration files, aircraft personal modules, registries, parameter data items, or lookup tables used by airborne systems and equipment to adapt equipment to the aircraft (i.e., airborne system databases) are not applicable. b. This CTSO affects new applications submitted after its effective date. It describes the requirements for the applicant’s data processing procedure, quality management, and data quality. However, any major change to data processing procedures, quality management systems, or data processing tools must be reported to the authority and may only be implemented after its approval. c. Data updates under the authorized processing procedure and quality requirements of this CTSO have no needs to go through the change approval process. d. Databases produced under the approval of this CTSO may be installed in their compatible equipment. When such compatible equipment obtains installation approval, the database may be installed along with the compatible equipment without separate approval from the authority. 3. Management Requirements. a. CTSOA Categories CAAC CTSO-2C611 - 3 - The airborne aeronautical data processes and associated databases CTSOAs authorized under this CTSO are classified into two types: Type 1 CTSOA and Type 2 CTSOA. (i) Type 1 CTSOA Type 1 CTSOA are based on data requirements agreed upon between a data supplier and their customer (typically an avionics manufacturer), a Type 1 CTSOA provides recognition of the aeronautical databases meeting the objectives of this CTSO with
