Engineering services - Quotec GmbH/Ltd.

Quotec provide safety risk assessments and analysis for aeronautical products as a team effort. We maximize utilization of  safety intelligence. Methods include: AFHA, PASA, SFHA, PSSA, SSA, FTA, CMA, ZHA, PRA to SAE ARP4761™A, ASTM F3230, and CS/Parts 23/25/27/29, RTCA DO-Series as required. We support SMSs, identifying safety critical items, functions, qualitative and quantitative objectives for requirements definition, or evaluation of CONOPS, RFI, RFP. AI and certification assurance is addressed and integrated with existing methodologies to support CVEs.

For managing uncertainty we provide reliability modelling, analysis, allocation, prediction, recording, normalizing, and reporting. R-requirements are identified with appropriate measures for mechanical, electrical, electronic hardware and software, (MTTF, FR (λ), Probability of Success (Ps), unreliability (Q). We assist setting reliability objectives for requirements, or evaluation of CONOPS, RFI, RFP. Analysis down to board level is supported. In-service reliability is supported with: data standardization, recording, normalizing, and intelligence. As required Root Cause Analysis is done to Test-Analyse-Fix-Test reliability issues.   

For system to equipment, we assist or provide complete maintenance policies (repair/replace), strategies, and processes, design for maintenance to hazard rate, λ(t). Maintenance subject include: time distributions, scheduled, unscheduled, MTTR, predictive maintenance, periodicities planning, value engineering. Technology considerations include: mechanical, electrical, electronics, software, BIT, condition monitoring, prediction: MTTR = Σ(λtr)/Σλ. Our solutions support maintainability inputs for drafting requirements, or evaluation of CONOPS, RFI, RFP.

For realistic availability we aim for minimizing down time, and modelling from duty cycles to availability, Ao, Aa, Ai, A(∞).  We aim to provide transparent readiness. We include supportability, and effectiveness relationships (humans, services). Availability basis, is down time, or time interval. Related metrics used are: MDT, MTBM, MTTF, and clarity on the use of MTBF. Project inputs for requirements, or evaluation of CONOPS, RFI, RFP.

We provide sustainment services based on life cycle principles, management, stages, processes, using IPS, ASD S-Series, resource modelling, ISO 15288, ARP4754™B, AAP48. Information quality is essential, and we use ASD S1000D, or ATA iSpec2200 for best practice reports and publications production, including focused language skills, i.e., Plain English, Controlled Technical English, Simplified Technical English. Additionally we provide through-life support analysis, and Life Cycle Costing.

In support of our core skills and services, we provide additional systems engineering services, considering a client's mission, operating environment, e.g., organization approvals, such as EASA DOA, and FAA Design Approval Holder. We scope from ICAO policies, and Recommended Practices, to project CONOPS, any Safety Management System to provide "fit for purpose" processes and applicable metrics. Data capture, library and information science, taxonomies, dictionaries, glossaries for projects are included. Essential aeronautical product configuration management is included, considering information as an asset with value engineering.
