skybook 1.39.0 Release Notes

Here is the March 2024 release notes update to skybook version 1.39.0. If you're interested in exploring the latest release features and enhancements in detail, feel free chat to our team.

Jump to the section:


New functionality is available to configure and calculate Last Minute Change information and share this between the skybook EFB and Ground Portal.

Enhancements have been made to the Record Vault, new notifications, and organised tracks information can be hidden in briefing packs.

The skybook EFB can now send fuel orders, and enhancements have been made to the Crew, Airfields, Nav Log, and Library modules.


Last Minute Change (LMC) Calculator

A new LMC Calculator has been developed for the skybook EFB, enabling flight crew to calculate changes and see the impact on the weight and balance of the aircraft.

On the Ground Portal, users can set the categories and weight defaults for the LMC Calculator as well as further configure areas such as PAX zones, cargo compartments, and their respective on and off load indexes within Fleet Settings for fleets or individual aircraft.

These settings define what the flight crew will see when using the LMC Calculator within the new Tools section. EFB users can move, remove, and add passengers, baggage or cargo; and then tap the Calculate button to receive instant feedback on how the changes will impact the weight and balance of the aircraft.

Once the EFB data is synced to the Ground Portal, any Last Minute Change calculations can be viewed under the Tools tab of the Sector Data screen within the Record Vault section of the Reporting & Analytics module.

Ground Portal updates

Sector History 

The Sector History screen within the Record Vault now has a filter applied by default to the Voyage ID column.

This means that upon loading the Sector History screen, only sectors where a voyage was created and downloaded, and therefore have a Voyage ID attached, will be displayed.

sector history flight voyage ID

Note: The filter can be removed at any time by clicking on the filter icon at the top of the Voyage ID column and then clicking the X to the left of the filter in the filters popup.


Notifications - new alert types

Two new notification types have been added to alert skybook Ground Portal users to the following OFP related statuses:

    • if the OFP associated with a sector has not been created/uploaded by xx minutes prior to the scheduled time of departure (STD);
    • if the latest OFP has not been downloaded by the flight crew to the skybook EFB by xx minutes prior to the STD.

The notifications are configurable by admin users within the Settings module by navigating to the Default Settings tab and selecting Notifications from the side bar:

scheduled time of departure notification ofp 

As with all other notification types, you can configure which user roles will receive alerts and choose whether they will see just the notification itself, or whether a sound will also be played.

Additionally, you are able to customise the period in minutes prior to the STD for both notification types by clicking on the fields and typing in the required time.


Hiding Organised Track Systems information in Briefing Pack

It is now possible to have no organised tracks information (NATS, PACOTS, AUSOTS, etc) included in the PDF Briefing Pack generated by skybook. This means that tracks will not be displayed on the charts included in the briefing pack, and the textual information will also be ommitted. 


skybook EFB updates

Integration Updates

AIMS Integrations

Custom crew and schedule time periods
For customers utilising the skybook AIMS integration, it is now possible to have the time periods for crew and schedule data ingestion customised. This enables individual operators to choose when the crew and schedule data is available to view within the Dispatch module.

Aircraft registration updates
In some cases when a flight plan was received, the aircraft registration was being changed when updates from AIMS were received. In this release, new settings have been made available which will prevent any mis-matches when updates are received:

      • When enabled, AIMS schedule updates will be prevented from altering an existing sector's aircraft registration is an OFP has been received
      • When disabled, AIMS schedule updates will be allowed to alter the aircraft registration

Regardless of whether the setting is enabled or disabled, any aircraft registration changes received via an AIMS schedule update will be implemented if an OFP has not been received.

Note: If the setting is enabled and an attempt is made to update the aircraft registration via the schedule API, an error message is displayed on the Dispatch screen:

Journey Log updates

Sending JourneyLog PDF via SFTP
In this release, functionality has been added which enables the Journey Log PDF file to be sent as a standalone document via SFTP to a customer endpoint.

JourneyLog .csv enhanced with additional fields
The following information can now be extracted from EFB flight data and added to the JourneyLog.csv:

      • Arrival station airport;
      • Aircraft registration/tail number;
      • Correct units used by the flight or aircraft (e.g. kg/lbs);
      • Crew ID for takeoff and landing.

PPS Integrations

Taking additional voyage data from PPS to add to EFF
Customers who utilise the PPS flight planning service in conjunction with the Aviator EFB can now have additional voyage data from the PPS Air Support service included in the EFFs that they download as follows:

      • Airport Weather PDF including TAF and METAR;
      • NOTAM;
      • Weather Charts.

The required data is taken from the PPS webservice, converted to the ARINC633 format and then included in the EFF package.You can select the relevant documents to include in the EFF by navigating to the Settings module and clicking on the EFF tab:

oyage data from PPS to add to EFF

Additional Integrations

Additional timestamp in Voyage Events JSON
In order to help with troubleshooting and to provide an enhanced audit trail, multiple timestamps are now recorded in the Voyage Events JSON file:

      • One timestamp shows when the flight was signed (for example in Aviator);
      • The second shows when the event reached skybook.

timestamp in Voyage Events JSON

SegmentTemperature values rounded down
For customers who use FlightKeys EFF flight plans, SegmentTemperature values received in the OFP.xml that are more than ten characters will now be rounded down to ten characters or less.

Example from OFP.xml showing value greater than ten characters:

Update to NCS NOTAM feed
Users of the Jeppesen NOTAM Cloud Service feed are now able to choose to edit, hide, and remove NOTAMs through the Planning Portal in the same way that customers who utilise the skybook NOTAM feed can.

Within the Planning Portal, select the airfields that you wish to view NOTAM information for and then navigate to the NOTAM section. Then click the Edit/Hide NOTAM button. 

You can now view all available NOTAMs for the selected airfield. Click the Hide button to hide a particular NOTAM or click the arrow to edit the NOTAM text:
