Support Engineering

Our support is embedded in our customer systems
Support engineering targets the 100% system availability and safety, i.e. zero failure of hardware and software. Therefore, highly reliable and optimally maintainable systems are demanded, including all related support items, spare parts, documentation, training, ground support equipment and processes. 


Fulfilment of critical objectives
Bertrandt Technology (formerly Philotech) engineers are supporting our customers in the fulfilment of such critical objectives with their expertise by:

  • Maximizing system availability and safety

  • Minimizing system downtime and maintenance efforts

  • Reducing life-cycle cost

 Teaming is key factor for success

Working hand-in-hand together with the customer's development and support teams is our daily practice. This ensures that planning and production work are concentrated towards identical goals and targets. It provides synergies with all parties involved and a high level of maturity is achieved - in systems and in processes during uptime and downtime.

 No "one fits all"

Maintenance and in-service programs have to be individually tailored to accurately meet the customer requirements. There is no "one-fits-all" answer since all customers and all systems are unique. Our highly skilled and dedicated engineers manage program planning and its continuous optimization.

Main fields of support engineering services

  • Reliability, maintainability and safety engineering

  • Maintenance program planning and optimization

  • Maturity program definition for in-service readiness

  • In-service performance optimization

To design a system for optimum availability at minimum cost

Operational key success factors such as total life-cycle cost, system reliability and optimum maintenance expenditure must be defined and designed into the product. This must be carried out during the early stage of the product development phase in order to realize the benefits during the product's operational life-time.

Supportability Engineering (RAMSST) for complex systems and challenging operational environments

An all-inclusive understanding of a 'system under development' is crucial in order to deliver the highest level of supportability. Reliability (R), Availability (A), Maintainability (M), Safety (S), Security (S) and Testability (T), often referred to as RAMSST, are the fundamental supportability design disciplines for a modern, state-of-the-art system development process.


Upfront development investments will be generously reimbursed during the systems operational life-time. Our RAMSST engineers perform systems analyses across many different industrial sectors such as commercial aerospace, defense, transportation, information technology and therefore ensuring that products operate in a highly dependable and a most cost-effective manner.

In order to minimize safety related risks during the life-cycle of a product the principles of Functional Safety as defined in the related standards, (e.g. SAE ARP 4754A, ISO 26262, IEC 61508) are applied. Please visit our dedicated Functional Safety section for further information.

 MSG-3: Maintenance Program Development and Maintenance Planning to minimize downtime and maintenance cost

The MSG-3 system analysis methodology for maintenance program development of new aircrafts is a key activity of our Support Engineering division. Our highly-experienced engineers positively influenced the maintenance design of today's most modern aircrafts such as the Airbus A380, A400M, and the A350XWB, making Bertrandt Technology (formerly Philotech) one of the preferred partners for maintenance program and maintenance planning activities.


 Aircraft diagnostics and Built-in Test Equipment (BITE) for precise troubleshooting

Providing an excellent design of built-in test equipment is a major enabler for effective aircraft troubleshooting resulting in minimum aircraft downtime. We achieve this with in-depth system knowledge and understanding. Exact fault isolation performance for effective line maintenance and quick LRU (line replaceable unit) identification is a key performance indicator for airlines.

 Maturity Management for a successful entry into service - HALT/HASS tests

 Integrated Logistics Support (ILS) needs more than just one

Bertrandt Technology (formerly Philotech) provides engineering support for all modules of Integrated Logistic Support (ILS): supportability analyses such as reliability, safety, maintainability and testability analysis. Based on the results, the availability of the analyzed systems can be determined and - if the preliminary results are already on hand in an early phase of the system engineering process - the system design can be optimized.

We support integration analyses like Logistic Support Analysis (LSA), Level of Repair Analysis (LORA) and Life-Cycle Cost (LCC) analysis. Our engineers are experiences with all of the standard tools for the individual support integration analysis based on MIL-STD-1388 2B and others. We are also developing our own system support engineering tool for LSA (ASSET), based on ASD S3000L and S4000M.


Bertrandt Technology (formerly Philotech) also supports elements required for the actual operation and maintenance during the in-service phase of the system. This comprises training and training equipment, test equipment, spare parts, technical publications and manuals, which are governed by the support integration analysis results.

Technical Documentation

We help to improve your customer service

The technical documentation is your access to the users of your products. A complete and understandable technical documentation leads to a positive user experience and increases customer satisfaction. This reduces the number of service inquiries and thus your cost in the aftersales process.

Bertrandt Technology (formerly Philotech) offers the entire spectrum of technical documentation, from research and creation to translation and publication, if required also in portals and multiple media. This includes also ensuring the CE conformity of your documentation or creating visualizations from 3D engineering data.

All services from one hand

Bertrandt Technology (formerly Philotech) offers the creation, revision and publication of technical documentation in the aerospace, automotive, mechanical and plant engineering and software development industries:

  • Aircraft and component maintenance manuals (AMM and CMM)

  • Service bulletins

  • Job instruction cards

  • ASD S1000D data modules for description, operation, maintenance and repair

  • User and operating instruction manuals

  • Service- and repair manuals

  • Maintenance manuals

  • Installation manuals

  • Spare parts catalogs

  • Data sheets

  • Software manuals for usage, installation, setup and administration

Cross Media Publishing

A modular creation of documentation in XML format allows you to publish your technical documentation in multiple media from one source and facilitates reuse of existing content. By using a state of the art authoring system, you reduce your costs for translation and desktop publishing and reduce the time you spend writing your technical documentation.

In case you already use a content management or an authoring system, we work together with you in your system to produce your technical documentation and relieve you of peak workloads.

Technical documentation for products throughout the world

Your products are used worldwide and therefore the related documentation must be published in many languages. We support you to optimize your technical documentation for translatability. After approval, we translate your documentation using a state of the art translation management system. This ensures a consistent translation with the highest possible reuse of existing translations.

Consulting on technical documentation

We advise you on the selection and introduction of your authoring system for a format-neutral creation of your technical documentation. To ensure that everyone involved pulls together, we work with you to develop your documentation style guide to ensure a consistent look and feel of your technical documentation.
