SEMPER - Part IV

Welcome to Wired!

The SEMPER process as described in this series has evolved over a multi-year time period while working the referenced programs and other similar avionics studies. Only ASIG and its teaming customers have applied all of the SEMPER principles throughout the planning and execution of avionics modernization programs. ASIG does not claim that SEMPER represents all new concepts. However, it is an approach to avionics planning and execution that emphasizes use of a migration strategy, life cycle or CAIV cost estimation and the application of Open Systems & COTS concepts.

In evaluating business considerations, the on-going acquisition reform process could be viewed as presenting a paradox with a proposition that advocates detailed analysis of the architectural alternatives, cost analysis and Opens Systems & COTS concepts. If aircraft owners/operators will only specify performance requirements and industry will propose the design solution then what is the purpose of the up-front and rather detailed study? ASIG does not share this view. While there is a level of frustration in stepping through the design process a second time, prior planning and market research sets the framework for understanding the range of possible solutions. Cost estimates prove invaluable to the customer/owner/operator in deciding the program approval and in the establishment of a budget for the program standup. The Open Systems/COTS approach can provide the "building codes" that let us upgrade avionics rationally, affordably, flexibly and within the timeframes needed by today’s mainstream and supplemental air carriers who seek to capture their own market share. While acquisition reform such as Sarbanes-Oxley has changed many paradigms and concepts, SEMPER does not appear to be at odds with this new way of doing business.

The planning and execution of avionics upgrades for legacy aircraft can be a challenging process for system and program managers as they work to incorporate operator needs into the aircraft systems in a timely and affordable manner. Over the past ten years the engineers and managers of ASIG have been involved in a number of avionics planning and execution programs and have defined the SEMPER model process from that experience. The SEMPER suggests that an overall migration strategy for the avionics upgrades, greater use of Life Cycle Cost estimation and the application of Open Systems concepts are the three principal legs of the process.

In our next edition of Wired we will address the benefits of WAAS-EGNOS & Space Based Augmentation Systems in relation to today’s CAN/ATM air traffic control environment. We will also look forward to 2026 and how the FAA and other international rulemaking bodies are retooling the future ATC environment.

Until next time stay 5x5, Mission Ready & Wired!
