Leon 203 released
We have recently initiated the deployment of a new version of Leon. Over the next coming days, customers will gradually transition to the updated version. If you encounter any functions that are not working as expected, please notify us via the Customer Portal.
Marketplace
- Marketplace functionality is now explained in new article available under following link.
 
Wingman chat
- We have released the first version of the AI Chat, designed to assist users working with Leon in their daily tasks. More information here.
 
Ops
- Added the ability to load fuel prices for bases/offices of an operator. Previously, all prices were global. Now the flight price can be loaded for the selected base, and those fuel prices will apply to flights planned on aircraft assigned to that base. You can still upload prices globally by choosing the "All bases" option in the top‑right corner of the page.
 - Improved the quick FDP calculator, which allows checking FDP without creating a trip:
- Added a field for aircraft registration selection, enabling automatic AOC selection based on the aircraft registration.
 - Implemented automatic flight time calculation based on the aircraft's Performance model.
 
 
Sales
- RFQ list: added a filter to search RFQs by Marketplace.
 
Reports
- Report Wizard: added the AI Assistant function for creating Excel report templates. This feature is analogous to the existing function for editing PDF/HTML reports.
 
Crew
- Added the Roster Validations feature to the Crew Timeline. This is the same functionality previously introduced to the Crew Calendar.
 - Crew Calendar: added display of the airport where the crew member is located on a given day. The information will appear only in empty cells. More information here.
 
Airport Directory
- Improved the interface for setting airport opening hours. You can now quickly apply the same hours to Airport, Tower, and Customs using the Save also to option. Simply select the checkboxes for the hours you want to update and save.
 
Crew app
- Added the ability to upload files to checklist items.
 - Modified filters on Schedule views to allow quick selection of all aircraft.
