New dataset: Fuel burn and CO2 emissions
We are pleased to announce the release of our new fuel burn and CO2 emissions add-on.
We calculate fuel burn and CO2 emissions by combining our satellite-based tracking capability with our fuel and emissions model. We currently provide fuel burn and CO2 emissions for ~98.8% of in-service regional, narrowbody and widebody jets (learn more).

New dataset: Tracked hours & cycles
In addition to our existing reported hours & cycles data (which covers ~50% of in-service regional, narrowbody and widebody jets), we are pleased to announce the release of our new tracked hours & cycles dataset.
This new dataset (derived from satellite-based tracking of aircraft) covers ~99.7% of in-service regional, narrowbody and widebody jets.

How commercial aircraft retirements are determined in Cirium fleet data
This post aims to explain how end-of-life commercial aircraft retirements are determined in the Cirium data research process.
NOTE: A separate Knowledge Base article explains how the Fleets Analyzer Projection feature determines future retirements using a non-researched based approach.Continue reading

Projection Module: The Retirement Model
Why are there so many retirements during the current period?
When using the Projections tab within Fleets Analyzer, and showing Retirement events, you may notice a large number of events during the current period (month, quarter, year), along with a corresponding drop in the number of in-service aircraft.
When there is no known retirement date for an aircraft, under the Projections tab, a basic retirements model is used. The model uses the following rules:Continue reading

Aircraft build location
We are pleased to announce that we have recently added Build Location to Fleets Analyzer. Build location represents the final assembly location and is assigned to individual aircraft.
In total, we have added build location to over 173,000 aircraft across all market groups. For the commercial fleet, we have build location for 88% of delivered aircraft.Continue reading

Team Share
Sharing your Saved Searches with other users within your organisation is a great way to make sure that everyone is using the same data and viewing the same reports. For large organisations with many Fleets Analyzer users, it’s quite easy to become overwhelmed with shared Saved Searches. In order to combat this “over sharing”, we’ve just added a new addition to the sharing options. In addition to sharing your Saved Searches with all the users within your organisation, you can now share with ‘specific people and/or groups’.Continue reading

Updated Field Picker
The ‘Field Picker’ (used when selecting columns, groups, metrics etc.) has been updated to ensure that the full name of fields is always visible, and no longer truncated. The old Field Picker is shown below in Figure 1, with the updated version shown in Figure 2.

Participants filter
In November 2017, we introduced the Participants field to Flight Fleets Analyzer as an optional column on the Aircraft Detail page, and in the header of aircraft profile pages.
Definition: Participant in a financial transaction, such as a loan, mortgage, tax lease, etc. The role of each participant could include (but is not limited to) arranger, debt provider, equity provider, guarantor, etc
To help find aircraft associated with specific Participants, we recently introduced the Participants filter. The Participant role differs slightly from the other nine company roles (Owner, Operator, etc) in that there can be multiple participants associated with an aircraft at any single point in time. Selecting multiple companies within the Participants filter will return aircraft if they are associated with any of the Participants: for example, Participant 1 OR Participant 2. This is shown in the example in Figure 1.Continue reading
