About SAFTE-FAST
SAFTE-FAST is the validated and widely used fatigue model used to assess fatigue for an entire workforce.
In aviation, it is the same model used by the US Federal Aviation Administration suitable for assessment of pairings, planned rosters, and as-flown rosters.
SAFTE-FAST provides an integrated and science-based process for analysis of fatigue risk in an entire workforce or in individual cases, identifying fatigue factors that inform mitigation decisions.
SAFTE-FAST provides the most trustworthy predictions of crew performance that maximize the benefits of fatigue risk management, improve safety, minimize errors and incidents, improve morale, and enhance productivity.

How to integrate Leon with SAFTE-FAST
Integration with SAFTE-FAST is available in the ‘Settings’ > ‘Add-ons’ section > ‘Risk Management’ subsection.
In order to integrate with SAFTE-FAST you need to contact the company at info@saftefast.com and require integration with Leon. SAFTE-FAST then contacts Leon and Leon switches the integration to ‘ON’.
How the integration works
Once the integration is activated, the SAFTE-FAST option will be available in the ’Crew Timeline view.
There are 2 ways in which the crew data can be analyzed:
-
Per single crew member
-
For all crew members
The color red on the Crew Timeline can signify either a Flight Time Limitation (FTL) violation or a SAFTE-FAST threshold exceedance. To identify the specific alert, right-click on the duty. If no FTL alert is shown, it indicates a SAFTE-FAST alert.
Analyzing data per single crew member
In order to receive a fatigue score for a single crew the below steps need to be followed:
-
Right-clicking the mouse on the crew code in the Crew Timeline
-
Select the ‘SAFTE-FAST’ option in the dropdown menu
Selecting the ‘SAFTE-FAST’ option for a particular crew member will result in SAFTE-FAST analyzing the crew fatigue in a pop-up window in Crew Timeline.
Initially, ’Waiting for the server to download proper data from SAFTE-FAST message will appear.
If there is no data in a given period, ‘Nothing to calculate for a user -USER CODE- in given time period’ message will appear.
After few moments, Leon will display the results from ‘SAFTE-FAST’ in the form of a table including:
-
Effectiveness score on departure and arrival
-
Reservoir score on departure and arrival
-
Percent Below Criterion on a flight
The score brackets are as follows:
-
Effectiveness
-
- indicates ‘Exceeded’ and applies to the values ≤65
-
- indicates ‘Warning’ and applies to the values >65 and ≤77
-
- indicates ‘Soft Warning’ and applies to the values >77 and ≤90
-
- indicates ‘Good’ and applies to the values >90
-
-
Reservoir
-
- indicates ‘Exceeded’ and applies to the values ≤65
-
- indicates ‘Warning’ and applies to the values >65 and ≤75
-
- indicates ‘Soft Warning’ and applies to the values >75 and ≤90
-
- indicates ‘Good’ and applies to the values >90
-
-
Percent
-
Exceeded for values >20
-
Warning for values > 10
-
Soft Warning for values > 1
-
`
The data is analyzed based on the flights, positionings, and duties, and for the flights and positionings within a timeframe selected in the Crew Timeline filter.
The data is analyzed within Leon based on the SAFTE-FAST model. Leon does not send any data to SAFTE-FAST.
Analyzing data for all the crew members
It is also possible to monitor Crew fatigue in the Crew Timeline for all the crew members in a selected period of time.
In the main ‘Crew Timeline’ view, click on the 
Once the analysis has been performed, to show the level of Crew fatigue, Leon will highlight lines in either orange or red colour.
The orange The orange color of the line indicates:
Effectiveness ≤ 77
Reservoir ≤ 75
Percent below criterion › 10
The red The red color of the line indicates:
Effectiveness ≤ 65
Reservoir ≤ 65
Percent below criterion › 20
REPORT
You can generate a SAFTE-FAST Export report from the ‘Reports’ menu. This report is exported in CSV format, which can be imported into SAFTE-FAST standalone software solutions. You can create the report for an individual crewmember or for all crewmembers over any past period.
