What is SAFTE-FAST and how to enable it

The SAFTE-FAST integration allows Safety Suite to calculate fatigue and alertness scores using validated biomathematical models. 

These scores support fatigue risk management by identifying potential fatigue exposure during rostering and timesheet verification.

The integration uses duty and flying duty (FDP) information already recorded in Safety Suite and operates in a similar way to the FAID Quantum integration.

How it works

Safety Suite builds schedule data for SAFTE-FAST analysis based on how shifts are configured in the Roster.

The following principles apply:

• SAFTE-FAST calculations use Duty and Flying Duty times recorded in shifts

• Flying Duty Periods (FDP) must be fully contained within a Duty block

• The user’s current base (home or touring) is used to account for time zone impacts

• SAFTE-FAST results are checked during Roster and Timesheet verification

Steps to enable SAFTE-FAST

Enabling SAFTE-FAST is a one-time setup process. Once enabled, fatigue scores are calculated and displayed automatically.

To enable the integration, complete the following steps in order:

1. Assign access levels

2. Enable the SAFTE-FAST integration

3. Configure location codes

4. Verify SAFTE-FAST results

Step 1: Assign access levels

Only authorised users can configure and manage the SAFTE-FAST integration.

To assign the appropriate access, go to a user's Access Levels page and assign"Modify All" access to SAFTE-FAST Integration. 

You can also assign this access via an Access Template. How to create (and edit) an Access Template

This access would typically be assigned to managers who perform rostering activities.

Step 2: Enable the SAFTE-FAST integration

1. Go to Site Setup > Integrations > SAFTE-FAST Integration
   
   
   
   The Setup page should open.
   
   
    

2. Tick Enable SAFTE-FAST Integration at the top of the page
    

3. Configure optional settings as required:

   • Time Reference - defines which time zone is used for calculations

   • Effectiveness Thresholds - sets fatigue tolerance levels for your organisation
      

4. Click Save to save any changes

Step 3: Configure location codes

SAFTE-FAST requires airport codes to calculate fatigue accurately.

1. Go to the Menu > Locations module
    

2. Open the Location Register tab
   
   
    

3. Select Details on a location
   
   
    

4. Enter a valid IATA or ICAO airport code in the Location Code field (for example, LAX, or KLAX)
    

5. Click Save
    

The location code automatically propagates to the associated base.

Note: Every location linked to a base must have a valid location code. Missing or invalid codes will prevent SAFTE-FAST from generating results.

Step 4: Verify SAFTE-FAST results

After the integration is enabled, SAFTE-FAST scores are checked during both Roster and Timesheet verification.

• Roster: via the Verify option
  
  
   

  1. Go to the Rostering module

  2. Select Menu > Verify

  3. Review the verification results.  The results will follow the same colour pattern as other exceedances.

  4. Open a shift Query view to check SAFTE-FAST score in the Work Practice results table (at the bottom of the list).

• Timesheets: scores show automatically within the Work Practice column
  
  
   

  1. Open Timesheets.
     You'll be able to see the scores in the Work Practice column, with colourful backgrounds applied.

  2. Click on the icon next to the Work Practice name to view details of all Work Practice rules, and the SAFTE-FAST score 

  3. SAFTE-FAST score is located at the end of the list.
      

SAFTE-FAST scores are available in both classic and PWA timesheets.

FAQs
  

• Why do some shifts not return any SAFTE-FAST results?

SAFTE-FAST requires complete duty patterns to generate fatigue scores. Confirm that:

• Flying Duty Periods (FDP) are fully contained within a Duty block

• Shift codes follow one of these structures: Duty only, Duty with FDP inside, FDP only

If FDPs sit outside duty blocks, SAFTE-FAST results will not be generated.

• Why do SAFTE-FAST scores look incorrect or inconsistent?

Inconsistent results can occur if:

• Locations used in rostering are missing a valid Location Code (IATA or ICAO)

• The user’s home or touring base is not configured correctly, affecting time zone calculations

• Flying Duty Periods (FDP) are not fully contained within Duty blocks, preventing complete duty patterns from being formed

Check these configuration areas to ensure SAFTE-FAST can generate accurate and consistent fatigue scores.
