FRMS FOR AVIATION

The first practical application of the SAFTE model was for the US Air Force, which sponsored the development of the Fatigue Avoidance Scheduling Tool - FAST. So the heritage of SAFTE-FAST is firmly rooted in aviation experience and needs. SAFTE-FAST is the modeling system used by the US FAA and more than two dozen aviation organizations around the world, including all the major airlines in the United States. The reason for this success is confidence in the model and practical utility of the tool. The software contains a long list of aviation specific features, unsurpassed by any competing system.

General

  • Based on over 10 yrs. of experience with aviation, used by US FAA
  • Integrates with any scheduling system
  • Proactive and reactive analysis
  • Batch processing of unlimited pairings and rosters
  • Real-time analysis
  • Local PC, server or web-based

Sleep Estimation:

  • Varies with time zone crossings
  • Napping and in-flight rest schemes
  • Rest facility classification
  • Split duty rest schemes
  • Configurable and trainable

Inputs-consideration of:

  • Unlimited time zone changes with waypoints and airport codes
  • Crewing and not crewing (flight time, ground duties, deadheading, etc.)
  • Augmentation and split duties
  • Briefings and de-briefings
  • Sit-times betweeen flights
  • Variable commute times (option)

Outputs:

  • Manager table sorts for outliers
  • Flight time effectiveness (crewing time)
  • Critical time effectiveness (takeoffs/landings)
  • Airports, pairing codes, user-defined sort terms
  • Variable criterion
  • Dashboard of NTSB fatigue factors
  • Sleep reservior (sleep debt) and lapse likelihood
  • Aviation specific workload
  • FAST graphical display of waypoints, duties, sleep, night/day, effectiveness, etc.

SAFTE-FAST for Aviation is suitable for both prospective and reactive evaluation of fatigue. The system can link with corporate scheduling systems (see SAFTE-FAST Center) to provide efficient modeling of aircrew fatigue at every stage in the schedule planning and execution process.

The Modeler provides a rapid method for batch processing all aircrew schedules as a single process and the Manager provides a table of results to rapidly sort all schedules by a range of built-in fatigue metrics. Each schedule in the Manager table links to a graphical program called Visual FAST, which can be used to assess fatigue factors in any planned schedule and to conduct root cause analysis of fatigue reports, potentially leading to scheduling rules to avoid excessive fatigue in future planning.

A real-time fatigue assessment system - RealFAST - can serve as a fatigue information decision aid during irregular operations and rescheduling.
