With the majority of Mainline and Aircraft, Crew, Maintenance & Insurance (ACMI) fleets returning to pre-2020 activity we have updated our rules for defining an In Storage status.

During the pandemic tolerances for a Storage status were reduced as the frequency and certainty of Storage events increased. As incidents of Storage are now decreasing, we have expanded the length of time a commercial aircraft must be parked before a Storage status is applied.

If a commercial aircraft exceeds these tolerances a Storage status will be applied. The parking tolerances for Commercial Fleets are:

• 60 days for narrowbodies.
• 90 days for widebodies.
• Unless at a known storage site where a return off-lease or parting out may happen.

Please be aware of minor changes to TU & Emissions figures as we continually improve our methodology to bring you the industry’s most accurate data.

The data team at Cirium has updated the methodology which has a number of accuracy improvements resulting in changes to flight fuel and CO2 emissions figures.

Tracked Utilization also includes a number of data quality and coverage improvements resulting in more flights for more aircraft being tracked.

Dear customers,

We have updated all columns & filters containing ‘Country’ or ‘Countries’ to now display as ‘Country/Subregion’ or ‘Countries/Subregions’. 

The change has been made to more accurately summarise the data these columns & filters represent. 

Please be aware this will have an impact on saved excel functions, which will need to be updated accordingly. 

Thank you for your cooperation.
