Leon 156 released

We have just started rolling out a new version of Leon. Over the next few days, customers will be gradually switched to a new version. If you find a function not working as expected, please let us know via the Customer Portal


  • OPS CALENDAR - flight tiles in OPS CALENDAR will display the tags assigned to flights or trips. More information here
  • OPS TABLE - we will revert to the rule that all commercial flights are marked in OPS with green colors and non-commercial ones with blue
  • AIRCRAFT PROFILE - a new field called MLW (Maximum Landing Weight) will be added to the aircraft profile. This field will be located in the tab 'BASIC' next to the MTOW (Maximum Takeoff Weight) field and the selected weight unit will apply
  • FLIGHT SUPPORT - possibility to share the Pax details with providers such as Jetex, Avior, etc.. More information here
  • JOURNEY LOG - the following approaches will be added to the Journey Log - IGS, and HUD / EVS-A
  • FOREFLIGHT INTEGRATION - flight time update functionality will be improved by also updating the block times and the schedule (STA)
  • FLIGHT WATCH - auto-filling of 'BLOCK ON' time will be possible when receiving FW from Eurocontrol. To have BLON filled in automatically the 'Auto BLON' checkbox will need to be ticked in the EUROCONTROL 'Configuration' section. Once the setting is activated, the calculation will be based on LDG from Eurocontrol and TAXI IN time from the Airport Directory


  • CONTACTS - the 'EXPORT DUPLICATES' option will be added to the Phonebook. This option will allow the creation of a report with potential duplicate entries. The data within the report will be separated into two tabs: 'Person' and 'Company'
  • CONTACTS - the method of warning about duplicates during contact creation will be enhanced. The range of values identifying duplicates will be expanded and an additional warning before saving the contact will be added
  • CONTACTS - the 'Date of Birth' field in the contact profile will no longer accept future values


  • CREW CALENDAR - auto-roster functionality will be improved. More information here


  • FUEL PRICES - it will be possible to upload the Mineral Oil Tax rates.
