Airworthiness and Systems Safety Assessment
(Session Code: AES7)

Room Ballroom C  1:30 p.m.

Since its publication in 1996, the use of AEP4754A has become widespread across the aerospace industry. Updates incorporated in the latest revision of the document are covered, along with specific concerns for aircraft systems safety, wuch as associated Design Assurance Levels, redundancy, engine containment, lightning threat, atmospheric neutron single event effects (SEE) and fuel tank failures.

Structured Development per ARP4754A – Benefits Beyond Certification
In 2010, the SAE S-18 Committee completed the revision and publishing process of ARP4754A, “Guidelines for Development of Civil Aircraft and Systems”. This revised recommended practice includes the guidelines for developing aircraft and system functionality using a structured process with activities and objectives of the process determined by the safety aspects of the functions being developed. A development assurance level modulates aspects of the process based on the safety aspects such that more rigor is applied in the process for the more safety critical functionality.

Honeywell TSO Process in Response to FAA Order 8110.37E
TSOA applicants have typically used software and AEH Designated Engineering Representatives (DERs) in their software and AEH development processes in support of the TSOA applicant’s statement of conformance to the applicable TSO standard(s). Previous policy allowed these DERs to submit FAA Form 8110-3, for approval of life cycle data, as evidence of compliance to the RTCA/DO-178 and RTCA/DO-254 objectives. With the release of FAA Order 8110.37E, effective May 30, 2011, use of the FAA Form 8110-3 is no longer allowed in support of an application for TSOA. The FAA has removed the approval delegation of software and AEH for approvals done under the TSOA process. The applicant’s statement of conformance serves as evidence that all applicable objectives of DO-178 & DO-254 have been met. In response to this change in policy, Honeywell has implemented an internal program to manage the TSO Approval process which closely parallels the previous system whereby DERs were used, providing a structured methodology for approving data in support of TSO Authorizations and subsequent modifications. This discussion will outline the internal program used by Honeywell which has received positive comments from the FAA and given greater flexibility for Honeywell to utilize its global resources.
