During early 2015, our development team created a new database, titled ‘Flightpath’, this single database replaced the multiple databases that had previously powered both ACAS and Ascend Fleets. In order to present this single database to users, we decided to build a single web-based front end that was as powerful as ACAS, yet as easy to use as Ascend Fleets. During July 2015 we released the first version of this new tool, Flight Fleets Analyzer.

Launch of Version 1

Launch of Version 1

The first version of Flight Fleets Analyzer was launched in July 2015. Version 1 contained just three search sections: Aircraft, Aircraft Events, and Companies. With the launch of Version 1, users of ACAS started to migrate over to Flight Fleets Analyzer.

Dec 2015

200 more columns!

200 more columns!

During December 2015 we added a further 200 columns of data to the Aircraft section, all related to the internal fit of the aircraft (seats, IFE, etc). As well as this internal dataset, we also added Aircraft Values, Print Profiles, Company Category and Status, and improved the formatting of exports.

The Projection module, and a whole new section

In early 2016 we brought back the Projection module, which was previously available in ACAS 2.5. We also added a new section, Maintenance, and a new optional dataset, Aircraft Availability.

Mar 2016

More data fields, and a new feature

During March 2016 we added a couple of new fields: Operator Delivery Date, and IATA/ICAO codes. We also updated the Trend/Projection tabs to allow users to group by serial number: ie, grouping by one. This feature is useful when looking at the monthly hours and cycles for single aircraft.

Apr 2016

Old and new registrations, and 50% faster profiles

During April 2016 we responded to customer feedback and made aircraft profile pages load 50% faster. We also updated the Quick Profile Search to include old and future registration numbers for users trying to find specific aircraft. We also added the “Companies in this role” feature that’s available from company-related column headers.

In order to better visualise changes over long time periods, we added the ability to chart the metrics shown on the Trend and Projection pages. We also made further improvements to search speed.

Tying together orders

In late 2016 we introduced the concept of Order ID. This ID can be used to group together aircraft that are part of the same order. We also introduced another level into the aircraft hierarchy: Minor Variant.

Dec 2016

Start of Ascend Fleets user migration

The migration of ACAS users ended in December 2016, and we then started to move Ascend Fleets users over to Flight Fleets Analyzer. One the features that Fleets Analyzer lacked, and that had been part of Ascend Fleets, was totals on the Summary pages. This was added during December, along with the ability to group by order date, as well as Total Period Utilisation on the Trend/Projection pages.
