DAT.TR.100 Working methods and operating procedures

Regulation (EU) 2017/373

The DAT provider shall:

(a) with regard to all the necessary aeronautical data:

(1) establish DQRs that are agreed upon with the other DAT provider and in the case of a type 2 DAT provider, with the equipment design approval holder or an applicant for an approval of that specific design, to determine the compatibility of these DQRs with the intended use;

(2) use data from an authoritative source(s) and, if required, other aeronautical data verified and validated by the DAT provider itself and/or by other DAT provider(s);

(3) establish a procedure to ensure that the data is correctly processed;

(4) establish and implement processes to ensure that the tailored data provided or requested by an aircraft operator or other DAT provider shall only be distributed to the requester itself; and

(b) with regard to attesting staff that sign the statements of conformity issued under DAT.OR.105(b) ensure that:

(1) the knowledge, background (including other functions in the organisation), and experience of the attesting staff are appropriate to their allocated responsibilities;

(2) it maintains records of all attesting staff which include details of the scope of their authorisation;

(3) attesting staff are provided with evidence of the scope of their authorisation.

COMPATIBILITY WITH CERTIFIED AIRCRAFT APPLICATION/EQUIPMENT — TYPE 2 DAT PROVIDER

A Type 2 DAT provider should perform tests to ensure that the database works as intended with the application by performing sampling checks on individual data sets (e.g. in a simulation/test bench environment).

DATA SOURCE

In reference to the ‘data source’, please refer to AMC1 DAT.OR.100(a) ‘Aeronautical data and information’.

DATA EXCHANGE

To support data integrity, the DAT provider may use digital data sets as a preferred means of data exchange.

DATA PROCESSING

The DAT provider should keep the records for a period of at least 3 years after the end of the validity period of the database unless otherwise specified by other applicable requirements.

SIGNATURE

The attesting staff, authorised by the DAT provider, may sign the statements issued in accordance with DAT.OR.105(b) manually or in a digital manner (e.g. digital signature).

ATTESTING STAFF

(a) To qualify as attesting staff, appropriate knowledge, background, experience and specific training or assessment established by the DAT provider should be required.

(b) Training should be provided to develop a satisfactory level of knowledge of organisational procedures, processes and products, aviation law, and associated IRs, AMC and GM, relevant to the particular role.

(c) In addition to the general training policy, the DAT provider should define its own standards for training, including qualification standards, for personnel to be identified as attesting staff.

(d) The training should be updated in response to experience gained and technological advancements.

RECORDS OF ATTESTING STAFF

(a) The following is the minimum information that should be recorded by the DAT provider in respect of each attesting staff member:

(1) name;

(2) general training and standard attained;

(3) specific training and standard attained;

(4) continuation training, if appropriate; 

(5) background experience;

(6) scope of the authorisation; and

(7) date of first issue of the authorisation.

(b) The record should be kept in an appropriate format and should be controlled through an internal procedure of the organisation. This procedure could be part of the management system.

(c) The DAT provider should ensure that the number of persons authorised to access the system of personnel data record-keeping is limited and an appropriate access control mechanism is in place.

(d) The attesting staff member should be given access, upon request, to his or her own records.

(e) The DAT provider should keep the record for at least two years after the attesting staff member has ceased employment with the organisation or the withdrawal of the authorisation, whichever occurs first.

RECORDS OF ATTESTING STAFF

Records of the attesting staff may be stored electronically.

EVIDENCE OF THE SCOPE OF THE ATTESTING STAFF AUTHORISATION

(a) The authorisation document should clearly indicate the scope of the authorisation to allow attesting staff and any other authorised persons to verify the privileges.

(b) Attesting staff should make the authorisation document available to the competent authority upon request.

DAT.TR.105 Required interfaces

Regulation (EU) 2017/373

The DAT provider shall ensure the necessary formal interfaces with:

(a) aeronautical data source(s) and/or other DAT providers;

(b) the equipment design approval holder for type 2 DAT provision, or an applicant for an approval of that specific design;

(c) aircraft operators, as applicable.

INTERFACES WITH THE AERONAUTICAL DATA SOURCE AND/OR OTHER DAT PROVIDERS

(a) The DAT provider should demonstrate that formal interfaces with aeronautical data sources or other DAT providers are implemented. Procedures should be established to communicate instances of erroneous, inconsistent or missing data to such providers and monitor that timely and effective responses are received.

(b) Where resolution and correction cannot be obtained for data that has been called into question, the DAT provider’s procedures for dealing with this situation should ensure that the DAT provider communicates the alteration or removal of data which the aeronautical data source and/or other DAT provider has not concurred with or resolved. The DAT provider’s procedures should confirm that effective controls are in place to ensure that an unsafe product is not released and that such concerns are communicated to customers in accordance with the requirements laid down in DAT.OR.200.

INTERFACES WITH THE AIRCRAFT EQUIPMENT DESIGN APPROVAL HOLDER FOR TYPE 2 DAT PROVISION

The DAT provider should demonstrate that formal interfaces exist with the equipment design approval holder. In particular, the DAT provider’s procedures should stipulate that the equipment design approval holder communicates and responds to issues and constraints concerning compatibility/eligibility for installation between their equipment and the databases of the DAT provider.

INTERFACES WITH AIRCRAFT OPERATORS — TYPE 2 DAT PROVIDERS

The Type 2 DAT provider should demonstrate that a formal interface with aircraft operators is in place to confirm that operators’ requests are clearly defined and subject to review.
