Conference Contributions (Starts with most recent activities)
Fatigue Risk Assessment Methodologies
ICAO Fatigue Management Symposium | Montreal | 5. April 2016
After Kristjof Tritschler has been invited to support the ICAO FRMS Task Force, he provided some key concepts for the fatigue risk assessment sections of the new Fatigue Management Guides (FMG). This presentation complements the FMGs, explaining what types of fatigue risks may be assessed by using different severity classifications for fatigue risk assessments.
Fatigue Risk Assessment and Effectiveness of Mitigations
EASA | 2nd FRMS Workshop | Cologne | 04. Nov. 2015
Kristjof Tritschler illustrates different methodologies to assess fatigue risk, based on the most recent work with the ICAO FRMS Task Force. In the second part, the effectiveness of mitigations is shortly addressed. Risk assessment as well as the selection of effective mitigations are key processes for a FRMS. A conference paper has been published titled “Fatigue Risk Assessment Methodologies”.
Fatigue Assessment and Mitigation Methodology
FRMS Forum | Luxemburg | 7. May 2015
Kristjof Tritschler outlined that the typical risk assessment methodology of “severity x likelihood = risk” is of limited applicability for human fatigue. The “Fatigue Factor Assessment and Mitigation Table”, developed by the speaker, has been explained in detail, where different options are considered to mitigate fatigue risk for a specific duty or shift. A conference paper has been published titled “Fatigue Assessment and Risk Mitigation Table”.
The Germanwings FRMS Experience
EASA | 1st Workshop on the Approval and Oversight of FRM | Cologne | 26.Nov. 2014
Kristjof Tritschler illustrated his operational FRMS experience relevant to the next ORO.FTL. Regulations. From the starting point in 2006 up to 2014. Shared experience included a possible conflict of a tailored performance driven FRMS and a bureaucratic FRMS, as a result of a regulation or standard to be complied with. With the performance indicator shown at the conference, Germanwings has been one of the first airlines that has demonstrated measurable safety improvements through their FRMS.
Update on FRM: Staying Alert in 2014
Flightglobal Safety Conference | London | 16. Sep 2014
Kristjof Tritschler presented how Germanwings addresses the new EASA Part FTL Regulations, becoming effective by February 2016. An overview about the improvements was provided highlighting the responsibilities of the operator, new requirements of “appropriate fatigue risk management” and when an approved FRM is required.
Culture and Consistent Safety in Fatigue Management
FRMS Forum | Paris | 8. Oct. 2013
Where fatigue has traditionally been managed through prescriptive regulations in a compliance based culture. This presentation explained that a significant cultural change is required to make a FRMS effective. The culture of an organisation will need to develop form a “compliance culture” towards a “performance culture”.
The Germanwings Fatigue Risk Management System
DLR Conference F.I.T. | Cologne | 14. Mar. 2013
Speaker: MSc Kristjof Tritschler. Based on the used framework it was explained how fatigue may be effectively managed. The main message of this presentation outlined that even more restrictive prescriptive duty and rest time regulations will be of limited effect on the risks of fatigue, as long as circadian and workload factors are not considered over consecutive days.
A selection of results of a recent DLR-Study at Germanwings was presented to illustrate the influence of workload on fatigue. Further topics of future planned studies at Germanwings were shown as well.
Case Study – Successfully Managing Fatigue
Flightglobal Conference | Safety in Aviation – Asia < Singapore |8. May 2012
Speaker: MSc Kristjof Tritschler. This presentation addressed the real risks of fatigue, standards currently in place, the concerns of pilots and finally, what is needed to confidently achieve safety within and beyond legislation. The key message on this was, that if human limitations are respected, regulatory limitations become less relevant with a higher safety outcome.
Practical Experience using FRMS within FTLs
IATA/ICAO/IFALPA FRMS Seminar | CAA Headquarter | London Gatwick | 18. Nov. 2011
Speaker: MSc Kristjof Tritschler. The Germanwings FRMS was explained in the context of European regulations. It was outlined that Germanwings experience was, that managing fatigue risk through an FRMS requires a cultural change for the entire organisation, which needs time to develop. It is a step forward from a compliance based culture to a responsibility culture, moving towards a performance driven culture.
Case Study: FRMS – Implementation
Flightglobal Flight Safety Conference | London | 09. Sep. 2011
MSc Kristjof Tritschler has been invited to this conference to share experience of the FRMS implementation at Germanwings. The presentation reflected steps taken, based on SMS principles, taking into account the latest FRMS publications and guidance material from ICAO/IATA/IFALPA, FAA and EASA. It was outlined, that managing fatigue is a continuous process with measurable results in safety improvements, without loss of crew productivity.
FRMS – Experience within FTLs
FRMS Forum | ICAO Headquarter | Montreal | 01. Sep. 2011
Speaker: MSc Kristjof Tritschler. In order to manage the human risks of fatigue, Germanwings has built an FRMS since 2006. This presentation gave an overview of the Germanwings FRMS, including the role of the Fatigue Safety Acton Group. Germanwings demonstrated that an FRMS, as presented at this symposium by ICAO, IATA and IFALPA, provides the needed tools and methods to manage fatigue risk effectively, even within regulatory duty time limits (FTLs).
FRMS – Evolution or Revolution?
9. Deutsches Flight Safety Forum | Manching | 10. Mar. 2011
Speaker: MSc Kristjof Tritschler. Fatigue is no new hazard in the aviation industry, where duty time regulations and labour agreements are in place since decades. This traditional fatigue management however ignores additional and effective measures to manage the risks of fatigue. Today, FRMS is the accepted best industry practice with multilayered defences to complement existing prescriptive regulations. FRMS is considered the evolution in fatigue management.
The Effects of Workload on Flight Crew Fatigue
Flight Safety Foundation | 63rd IASS | Milano Italia | 05. Nov. 2010
Speakers: MSc Kristjof Tritschler. The presentation and conference paper contained the role of workload in a Fatigue Risk Management System. The results of the presented survey identified that 77% of the pilots rate the ground time between flights more fatiguing than performing the actual flights.
FRMS – Practical Application
ALPL FRMS Conference | Luxemburg | 3. Oct. 2008
Speaker: Kristjof Tritschler. This presentation at an international conference of fatigue experts covered the experience gained during the development and implementation of a Fatigue Risk Management System with Germanwings.
Fatigue Risk Management System
6. Deutsches Flight Safety Forum | Cologne | 12. Feb. 2008
Speaker: Kristjof Tritschler.
The presentation covered the basics of fatigue, causes, symptoms, consequences. But also the risks of fatigue and how fatigue can be managed in a Fatigue Risk Management System.
