Jeppesen CrewAlert
Mathematical Modeling of Crew Alertness
Alertness is a key aspect of fitness for duty for airline flight deck and cabin crews. Alertness and fatigue have become increasingly important issues as airplane capabilities have increased, and the complexity of flight operations have grown. Understanding how humans function in a complex 24/7 world has been a focus for scientists, regulators, and airline safety officers all over the world.
As part of a joint safety initiative, Boeing and Jeppesen have been developing tools for allowing better management of alertness and fatigue. CrewAlert is the first iOS application designed specifically to help airlines and their crews manage alertness and fatigue. Built on the Boeing Alertness Model (BAM), a mathematical model of alertness, the CrewAlert application puts scientific knowledge in the palm of your hands.
CrewAlert and the Boeing Alertness Model are evolving tools. As new science is added to BAM and new functions are made available in Crew Alert, updates will be posted to the App Store. Check back often to ensure you have the latest version.
Please note: This application is designed for professional pilots and the airlines that they work for. Before you purchase, please read this description in full as well as the Application License Agreement on iTunes to see if CrewAlert is for you.

BAM has been updated to run even faster than before. Release 2.2 is a pure performance boost to better support planning optimization runs for larger installations.
"Many of our customers are using planning optimizers that may generate several thousand rosters per second during several hours. Taking human physiology properly into account at this speed is very challenging", says David Karlsson, FRM Technology Lead Engineer at Jeppesen.
"In release 2.2 we have managed to speed-up the computations in BAM considerably resulting in a 185% performance boost. This ensures minimal impact on planning processes while guiding the optimizers away from fatiguing flight patterns."

Green Cargo, a Swedish cargo rail operator is now up and running using BAM with their crew planning optimizers. Even though regulation does not require FRMS of rail operators, Green Cargo sees the advantages with the Jeppesen approach:
"We've tried for many years to tweak our company rules to provide crew pairings and rosters for our staff that are nice to the body. Everyone have had their own opinion on on what is a good roster and our success down that route has been limited - to say the least.", says Johan Gerdvall, Planning Manager, at Green Cargo.
"With BAM integrated we can take fatigue into account during the highly automated construction process - the optimization. We're enabling not only production of less fatiguing rosters, but also evolving our rules forward safeguarding our efficiency."

A few years ago, Finnair became the first airline to plan their pilots with direct influence by a mathematical fatigue model during crew schedule construction. In recent months the airline has expanded its usage to also include fatigue “alerts” that are automatically pushed to the planners in day of operation. Now, supporting a performance-based approach, the human physiology is taken into account through the use of the Boeing Alertness Model – allowing for a more precise address of flight safety.
"The alert monitor is our main tool for not missing out taking action where needed," says Jari Ahonen, Crew Tracking Specialist at Finnair. "Fatigue alerts are now present as a new category in the monitor enabling us to put extra attention to problematic scheduling patterns - going beyond what regulation requires. Also during problem resolution, when recombining flights for our crew, we have fatigue indicators available in our planning GUI and can take that into account.”

The updated EASA FTLs were published January 31 and will come into effect February 18. Within 24 months all European operators will need to comply with these updated rules for crew flight and duty time. It is a major change for operators currently under CAP 371, but will also have a large impact on many using the current EU Ops.
Please find the new rules posted here.

What is a Fatigue Risk Management System, really? The ICAO FRM guidance material is quite comprehensive, many safety professionals have found it difficult to fully embrace the concept of FRMS and see a need of a concise simplification. For this reason we at Jeppesen have produced a one-page version you might find useful. Please find it through this link (pdf).

Nov 11, 2010
In the June 2010 issue of AeroSafety World, we analyzed several flight and duty time limit regulation systems in use around the world for controlling fatigue. Subsequently, the U.S. Federal Aviation Administration published its Notice of Proposed Rulemaking (NPRM) for “Flight Crew Member Duty and Rest Requirements,” which has spurred significant discussion in the United States as pilots unions, airlines and others attempt to understand the implications of the proposed rules.
In a new article, the authors extend their previous analysis to consider the NPRM, as well as U.K. rules, outlined in Civil Air Publication 371, “The Avoidance of Fatigue in Aircrews.”

CrewAlert 1.1 is now available on Appstore. This updated version “closes the loop” enabling airlines to collect fatigue-related data using CrewAlert and bringing it back to model improvement and validation. The functionality allows also for independent pilots to share their experiences uploading their schedule, actual sleep and alertness assessments and receive updated BAM parameters in exchange for their data.
For the first time there is now a solution available that schedules crew using sleep science, follows up what is actually experienced in operation, and then bring it back to model validation and improvement. Stay tuned for version 1.2!

Jeppesen Fatigue Risk Management Portfolio
Boeing and Jeppesen have jointly developed Fatigue Risk Management (FRM) functionality for allowing airlines to control crew fatigue and fatigue risk in crew planning and operation. The functionality is built into the Jeppesen Crew Management products so that scientific fatigue/alertness models can be accessed while constructing and maintaining crew schedules.
The FRM functionality allows for individual predictions on each flight of both crew alertness and associated risk. The alertness and risk information is available both in the GUI for the end-user but also to the optimizers during pairing and roster creation.
The availability of this information makes it possible to “build” alertness into rosters in the planning stage and to control and monitor it during manual roster maintenance and day-of-operation changes.
Alertness can be built into the crew schedules where it decreases fatigue risk the most – thus addressing the “tail” of the risk distribution. An operator may both use strict limits on fatigue risk, incentives to avoid the risk, alerts on risk thresholds, or any combination of these.
The Jeppesen rule engine RAVE, used in the Jeppesen Crew Management product suite, is able to connect to any scientific fatigue model compliant with CAPI, the Common Alertness Prediction Interface. CAPI enables high-speed integration with optimizers and aligns alertness prediction across models.
