The general view on OPS > Table section
Adding positioning duty and positioning option from a section Table

The philosophy of working in the section Table is to use filters to display desired activities in the middle section of the screen and then modify selected properties of those activities using the right-hand panel. Date range and format of displayed information can be altered using the top bar. By clicking TODAY Leon shows current day activities as well as other days.

You can select a number of days for flights view in the drop-down box (top-right corner of the screen), or leave as 'No Limit' to see as many flights as the screen can fit.

The refresh screen icon can be used for manual page refreshing, although Leon refreshes the screen every 2 minutes itself.

You can view flights and positionings duties. Legs of the same trip are marked with the thick, blue line. Positioning duties added from a section Crew > Duties (selected from the bottom of the duties list) also appear in Table. If there is a note inserted (in Crew > Duties), then those duties appear on white background as

When adding Positioning duty from Table, it is possible to add it as an option - it will appear in stripes (see screenshot on the right).

Leon will display type of flight by marking Flight no. column with the relevant colour. When you hover the mouse over the flight number Leon will show notes inserted into a tab FLIGHT (both: OPS & SALES).

Various types of flights displayed in different colours

You will also see Aircraft colour in ACFT column - the colour can be defined in a section Settings > Fleet.

If the flight is added as Ambulance, Cargo, Simulator or Training type, these types will display in the PAX column. In addition, Ambulance type flights will display the number of PAX in brackets if passengers are added, i.e Ambulance(2) for Ambulance type flights with 2 PAX.

'Flight change' feature

Flight change status in OPS Table

The colour coding used in that feature is explained in the table below.

Colour Meaning
New - the flight has been created and hasn't been acknowledged yet
Acknowledged - the flight is acknowledged and there are no new changes
Changed - the flight was acknowledged already but has been changed after that

Flight change status in OPS Calendar
Flight change status in OPS Timeline

The changes which trigger the status change from 'acknowledged' to 'changed' are:

  • aircraft
  • flight number
  • airports
  • times
  • crew

The feature is present in OPS Table, as well as in OPS Calendar and OPS Timeline. In the cases of OPS Calendar and OPS Timeline, the status will be indicated as a colour-coded left border of the flight.

The status can be changed to 'acknowledged' by clicking the corresponding button in the context (right-click) menu of the flight.

The button will appear only if the status is different than 'acknowledged'.

Editing trip

Editing trip - the view of the bottom panel

If you click button at the bottom of the screen an additional panel will show up.

If the selected activity is a flight, the whole trip (series of flights) will open in the bottom window with the selected leg in shaded green.

You can edit each column (Flight No., Date, STD/STA or PAX) and modify it. STA field will show an estimated time of arrival based on GCD and the aircraft perfprmance data inserted in its profile (which can be defined in a Fleet section), GCD including winds, archived flights (min. 5 on the same route) and Route Finder.

Quote number shows right before UTC/LT switcher:

You can also add a new leg in this section by clicking + or delete a leg by clicking

While you are editing a trip in the bottom panel, you can still use the right properties panel to access given sector details and modify them.

Apart from the standard schedule information, the bottom EDIT TRIP panel also shows 'Crew' column. This column has A/B format where 'A' indicates a number of cockpit crew and 'B' stands for cabin crew, e.g. 2/1 means 2 cockpit and 1 cabin. If there is no crew assigned Leon will mark it with '-' (2/- for no cabin crew). If you hover the mouse over the 'Crew' number indication Leon will display Crew codes assigned to the flight.

An additional option in Editing Trip panel is possibility of entering Cargo value. Switch to Cargo or PAX & Cargo in Settings > Flight Editing section in Trip edit scheme drop-down.

Leon will mark a cargo flight as 'Ferry' only if both 'PAX' and 'Cargo' are set to '0' in trip edition panel.


The transferring of a non-operating crew member from one place to another, at the behest of the operator, is an important thing in aviation industry. In Leon you can add positioning duties and assign crew in 2 easy ways.

Positionings in OPS

Default Positioning Checklist items
Positioning included in FTL calculation

You can add Positioning by clicking button at the bottom of Schedule view.

When a new window shows, enter details such as:Name, Date, STD, Departure, Destination and STA. Duration will calculate itself.

Clicking on Crew field allows you to select designated crew member from a drop-down box, or type-in his/her name or a code.

When adding Positioning duty from Table, it is possible to add it as an Option - it will appear in stripes, as all options in Leon.

Positioning duties added from a section Crew > Duties (selected from the bottom of the duties list) also appear in Table. If there is a note inserted (in Crew > Duties), then those duties appear on white background as

The right-hand filter contains 3 tabs:

  • Checklist - default items are: Crew aware of flight, crew transport & hotel. You can manually add more items by clicking a button ADD ITEM.
  • FTL - FTL Calculation Summary showing most important FTL regulations displayed in 2 columns: Limit & Actual.
  • Notes - an option to insert relevant notes for the particular positioning.

Multiple Positioning sectors

 function has an option to add more than one Positioning sectors for the crew.

Adding multiple Positioning sectors

To add multiple Positioning sectors you have to:

  1. Click on 'NEW POSITIONING' button and start inserting the details of the positioning as you normally would, including the crew.
  2. Make sure that checkbox is ticked.
  3. Click 'SAVE' to finish the process of adding the first Positioning sector. Leon will save the first sector and automatically populate the 'NEW POSITIONING' entry for the following sector with the existing Crew assigned. You can add or remove Crew at any time. The checklist on each new Positioning will reset to

In order to save the last Positioning, untick the checkbox and click on 'SAVE'. If the last Positioning has already been added and the “NEW POSITIONING' window populated, just click on 'CANCEL'.

It is not possible to add extra positionings to the ones that are already saved. In such case you need to add new positioning and follow the process.


Adding SIM duty

To add a new Simulator as the plan, click on button. Once a pop-up window shows, fill it in with details such as Aircraft type, Date, ADEP, ADES, BLOFF, BLON. Information inserted in the 'Place' field will display in the 'Flight No' column in the OPS view.

Additionally, it is possible to change the default reporting times in the 'Report on' and 'Report off' fields.

Initially, it is possible to add a SIM session without having to insert the crew as long as no Journey Log fields are filled in. Once the JL field is filled in, at least one crew has to be assigned.

Crew positions which can be added to SIM duty are CPT, FO, LTC, TRI, TRE, FE, FE2.

'Night T/O', 'Night LDG', 'Approach' and 'Approach type' fields will show only if these fields are activated in 'Flight editing' > 'Journey Log Items' section. When editing an existing Simulator session, these fields will show only if they were previously applied.

Once the SIM duty is done you can add details: T/O, LDG, Landings, Pilot Flying, Approach and Notes and Leon will show SIM duty in OPS with the grey colour indication and green dot.

In order to edit the Simulator, you need to click on it and the pop-up 'Edit Simulator' window will appear. There, you can update the relevant details and save the changes.

  1. Crew currency feature will work properly only when the field 'Pilot Flying' has been filled in with pilot/pilots codes. In a case where FO did take off and CPT did landing (or vice versa), you should add crew codes in a field 'Pilot Flying' as FO/CPT or CPT/FO.
  2. It is possible to add SIM session on a virtual aircraft. This could be useful when the crew have to be trained on an aircraft that is not yet a part of the fleet (purchase in progress).
  3. It is possible to add multiple Approaches & Approach types into one SIM session.

Adding a New Trip

In OPS you can add a new trip regardless of section you work with: TABLE, CALENDAR, or TIMELINE.

Adding a new trip in section OPS

Click the button NEW TRIP to add 1 or more legs. Select an aircraft, flight number (Leon assign it automatically if 'Default flight number' has been defined in fleet edition screen), date, STD, ADEP/ADES, STA. You can also add the PAX number or leave the trip as a ferry.

In section CALENDAR you can also add a new trip by right-clicking the mouse over the square.

Buttons UTC & LT allow switching between times while adding a new trip.

Flight time calculations

Leon suggests STA if a particular aircraft speed details are added in the fleet edition section, using GCD and/or average winds. STA suggestion can also be based on a minimum of 5 of the same historical routes.

Additionally, RouteFinder flight time calculations are available.

'RouteFinder' does not require separate integrations and is available by default in Leon.

'RouteFinder' calculates the flight times based on the routing.

In order to have the option available, the Include Route Finder time hint checkbox needs to be activated in the Flight editing section.

The flight time is calculated automatically and the dropdown suggests the block time value. It is based on the flight time calculation from the RouteFinder plus the taxi times from the Airport Directory.

'RouteFinder' also takes into consideration 'Exclusion zones' that can be set per Operator ('Sales Module' tab in 'General settings'), and the Fleet ('Sales' tab).

If an aircraft type is not available in the 'RouteFinder', the 'RouteFinder calculation will not be available in the dropdown.

The winds database will allow for more accurate flight time calculations in OPS and SALES sections. The winds data is available here.

To add more legs to the trip click + and to delete a leg click

You can also add a new positioning, new office, or new reservation by clicking appropriate buttons placed next to NEW TRIP.

Aircraft max range alert

We have added an alert if the max range of the aircraft is exceeded.

In order to get the warning working you need to make sure that the following fields are filled in in the Fleet section:

  • Capacity
  • Max range with PAX
  • Max range with 0 PAX
  • Aircraft speeds

When adding a flight, Leon will show a max range alert if:

  • field 'Distance' is filled in when adding a flight and higher than the max range for the aircraft in Fleet settings,
  • field 'Distance' is left empty or 0 inserted. In this case, Leon will recalculate the time of the flight into the distance based on the four values listed above.

If the range is exceeded Leon will also mark the aircraft red in the OPS view.

You can include ADEP/ADES Handler when sending the OPS/Sales/Custom documents. Handling agent has to be selected in the OPS checklist. If the Handling agent is not selected, the checkbox at the corresponding handler will be inactive. Additionally, the checkbox will be inactive if the selection includes positioning. The checkbox status is remembered by Leon.

Additionally, the documents can be sent to the 'Aircraft email'. This is the email inserted in the 'Fleet' sections > 'SALES' tab of edited aircraft details. The 'Aircraft email' is a BCC type email.

It is also possible to send the documents to CrewBriefing. More information can be found here.

If the trip is booked from the Requests/Quotes section, the 'SALES' part of the 'Documents Menu' will NOT be available (will not display). In such case, it will only be possible to print and send the Sales Documents available in the Requests/Quotes section of Leon.

Flight Order

Flight Order is an internal document generated for each trip required by CAA. In Leon, the format of this document can be customised. The Flight Order number looks like a date format, however, its number is a consecutive 'Flight Order' number issued in a particular month, i.e. 6-07-2013 means, that it is the 6th consecutive 'Flight Order' issued in July.

Flight Order patterns are available in Documents Manager panel - click select 'Flight Order' and view 1 of the 3 available templates. If you are happy with a particular one, insert the version and save. To publish it click the white dot.

General Declaration

Journey Log

Journey Log - entire trip post-flight data

In Leon you can add the Journey Log data in 2 ways:

  1. In the right-hand filter, tab FW & JL - here you can add data leg by leg, described in THIS CHAPTER of manual.
  2. By using button placed at the bottom of the screen, next to EDIT TRIP.

The 2nd way is useful if a trip has 2,3,4 or more legs, as Leon shows a Journey Log window for the entire trip, where you can easily enter post-flight data leg after leg. If you need more items to be displayed in your Journey Log you can add them in a section Settings > Flight Editing.

Flight times are mandatory to be inserted into the EDIT LOG panel for each leg, in order the trip Journey Log to be saved. If you have an option Allow not completed JL to be entered switched on in Settings section, you are able to save the Journey Log without fuel data (such input appears in the TABLE view as an orange dot, instead of green dot).

Trip changes history

Flights changes history - an option to check all actions done in the trip

To check all changes done in the trip you need to right-click with the mouse over a selected flight and click a link which opens a new window, where all changes are displayed.

In the changes history window Leon shows chronological list of all changes (the latest on top). The colours indication shows added data in green, changed data in yellow and removed data in red.

When you click on the changed detail, Leon highlights previous entrances of the same detail. On the screenshot below you can see highlighted STA 15:55, then also 15:43 (previous STA) and 14:42 (initial STA).

If the flight has been deleted in Leon you can still check its history (as long as the option to keep deleted flights as crossed-out is enabled) in case you want to know who deleted it and when.

Sending documents to CrewBriefing in PPS

Exporting to CrewBriefing

It is now possible to upload the documents to PPS directly from the Document Menu in the OPS.

It is possible to send:

Export to CrewBriefing window
  • one particular document - by clicking on the 'PPS icon' next to the document
  • batch of marked documents - by marking the documents you would like to send and clicking on the 'PPS icon' by the main section (OPS or SALES) in the document dropdown menu

The process of sending the documents is as follow:

  1. Open the 'Document Menu' in the OPS.
  2. Choose if you wish to send the documents per TRIP or per LEG.
  3. Choose the documents you would like to send.
  4. Click on the relevant 'PPS icon', depending on whether you wish to do that for 1 document or for the bunch.
  5. A window will pop up with the chosen documents. Click on 'SEND' button in order to send. It might happen that some of the documents woulnd't send on the first attempt. In such case, simply click on 'RESEND FAILED' until all the documents are marked with the green tick.
  6. Once all send, you should be anle to view them in CrewBriefing in PPS. The documents sent form Leon are merged into a file generated for Crew in CrewBriefing page.

It also is possible to upload files for multiple trips. To do so simply mark the trips you would like to send the documents for, open the documents menu and click on the relevant 'PPS icon'. If some of the documents fail to upload, the window will display the message as per below

When sending documents to PPS you have an option between doing it for First Flight or Per Flight.

Files uploaded in CrewBriefing

There are few scenarios possible of sending the documents to CrewBriefing:

  • In LEG mode to First Flight - all the documents attached to first flight and each pdf generated per leg, number of pages within one pdf
  • In TRIP mode to First Flight - all the documents attached to first flight and each pdf generated per trip
  • In LEG mode and Per Flight - each document attached to the relevant flight and each pdf generated per leg
  • In TRIP mode and Per Flight - exactly in the same way as in the LEG mode and Per Flight

After the documents are sent, in CrewBriefing, apart from the document type name, additionally, there is the routing indicated in the file name in CrewBriefing.


In order to send documents to PPS CrewBriefing, in PPS the flight needs to be dispatched to CrewBriefing and then it will be possible to upload docs from Leon to CrewBriefing.
Re-sending documents from Leon to PPS Crew Briefing will result in updating them also on CrewBriefing's side. This also applies to the documents that are sent to First Flight and then resent Per Flight - duplicates will be replaced according to the option selected. In CrewBriefing, if a document has not been resent it will not be overwritten, i.e. sending the Flight Order and GenDec initially and then resending the GenDec, CrewBriefing will keep the original Flight Order untouched. Analogically, it works in a similar way with the flights.
It is only possible to upload PDF format to CrewBriefing in PPS. The documents are stored in CrewBriefing for 3 days from the date of the flight after which they're removed from the database.
It is advised to send the documents using either First Flight or Per Flight.

GCR email example

On the attached screenshots you can find examples of GCR messages.

  • Flights on the same day - select the airport and Leon will show all flights from/to that airport.
  • Flights on different days - Leon will show only flights on the next day, omitting the following days.
  • Flights on the following day/days - when marking 2,3 days (or more) and selecting an airport, if flights are not on the first marked day but on the following day/days - Leon will show flights i.e. on the 2nd marked day omitting the 3rd marked day.

You can find an example of GCR message email in the screenshot on the right-hand side.

ASM messages

ASM message option

It is now possible to send Ad Hoc Schedules Message (ASM) from 'Show Schedule' section in Leon.

In order to send the message, you need to go to 'Show Schedule' option in the Documents Menu in OPS view and switch the option from 'Plain Text' to 'ASM' in the top-left dropdown.

'ASM' message email option will populate. Currently, there are 3 options available:

  • NEW - Insertion of New Flight Information - used to send the information about the new flights
  • CNL - Cancellation - used to send the information about cancelled flights
  • RPL - Replacement of Existing Flight Information - used to send the information about changes on the flights
The layout of the messages is with accordance to IATA's SSIM Manual, Chapter 5.

DCS & PSS systems.

SSIM (Standard Schedules Information Manual) panel in Leon (available in Settings), allows to send ASM (Adhoc Scheduled Message) messages to DCS (Departure Control System) & PSS (Passenger Service System) from a section OPS.

The 1st step to make it work is adding default email addresses in Settings > SSIM panel.

The 2nd step is sending ASM message to DCT & PSS systems from the checklist section of the panel OPS.

Each operator has 2 checklist items DCS & PSS available in the Settings > Flight Editing > OPS Checklist Items section. The items are not marked, so either need to be marked to appear on each single flight, or added from 'ADD ITEM' panel of the checklist in OPS section. Once added, they will appear with the SEND button.

Sending ASM messages to DCS & PSS

By clicking SEND button for DCS or PSS item, Leon shows a new pop-up window, which shows pre-defined message. Leon shows 3 types of messages in formats as on screenshots below (formats are the same for DCS & PSS systems). If no default email address has been added in Settings > SSIM, Leon will show a warning information: “DCS/PSS or 'From' email is not set”.

1. NEW - Insertion of New Flight Information - displayed when sending ASM message for the new flight.

2. RPL - Replacement of Exisitng Flight Information - displayed when re-sending ASM message to DCS.

3. CNL - Cancellation - displayed when a flight has been deleted.

Once ASM message has been sent out, Leon will change the checklist item's status automatically to 'Sent'. If the schedule was changed or a flight has been deleted, the DCS or PSS item's status will turn to '?'


It is possible to include IATA Service Type when sending ASM or SSIM messages from Leon.

The 1st step is to enable this functionality by marking a checkbox in the Admin panel, section 'Flight Editing'. In the same section it's possible to define a default IATA Service type

All available IATA Service types are explained in the screenshot on the right.

When enabled, the IATA Service type will show for each flight in the 'OPS' panel, tab 'FLIGHT'- it can be manually changed if necessary.

The list of IATA Service types

It also shows in the panel SCHED (when creating or modifying the schedule).

The main section where the IATA Service type will be especially useful is sending the ASM message window from the SHOW SCHEDULE panel.
