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 “”

A330neo taxonomy update

To standardise our taxonomy for the A330 type, we have amended the Master Series for the A330neo types from the generic A330neo to the relevant A330-800neo and A330-900neo.

Please be aware that any Saved Searches that include the A330neo as a filter option may need to be updated.

Following the Fleet recovery

During the peak period of commercial aircraft being placed into storage as a result of COVID-19 (March), we applied a “default” return to service of 30 September 2020. At that time, it was very much unknown what the lasting impact would be of the pandemic, but, from observing the fleet activities of the last few months, we have now started to review any remaining scheduled return to service dates. In reviewing the scheduled return dates until the end of the year, we have applied the following logic: Continue reading “”

OEM name changes

Based on customer feedback, we are making a series of OEM name changes to bring our data up to date with our policy of reflecting the current support OEM. These name changes will be implemented in Fleets Analyzer from 8 July.
IMPORTANT: if you have Saved Searches that contain the aircraft types or manufacturers listed in the table below, then please open your Saved Search (after 2pm 8th July – UK time) and update if necessary.

Aircraft Type Old Manufacturer New Manufacturer
DHC-8 Bombardier (De Havilland) De Havilland Canada
DHC-4 Bombardier (De Havilland) Viking Air
Convair 540 Bombardier (Canadair) General Dynamics
Convair 580 Bombardier (Canadair) General Dynamics
Kodiak Quest Daher
SC.7 Skyvan Bombardier (Shorts) Viking Air
Short 330 Bombardier (Shorts) Viking Air
Short 360 Bombardier (Shorts) Viking Air
Tucano Bombardier (Shorts) Embraer

Update on our Storage methodology

As of June 1st 2020 Cirium will be making a further adjustment to best reflect the current in service and stored fleets. However, we will not be retrospectively applying the new storage and in service classifications to data prior to June 1st 2020.


Aircraft will now be reflected as entering storage if any of the following criteria are met: Continue reading “”

Business aviation order data

The world of business aviation has always had a degree of secrecy about certain elements of it, and nowhere is that more obvious than in order data.

Order dates for business aviation shown in Fleets Analyser tend to come in two different types. There are known orders – which are a minority – where a major operator has made a multi aircraft order that the OEM in question is happy to publicise, and then there are the unknown orders which tend to be small and single aircraft orders where non-disclosure agreements are commonplace.

New usage type: Spares Use / Parts Reclamation

Based on customer feedback, we have introduced a new type of ‘usage’ to our database. The new usage is ‘Spares Use / Parts Reclamation’.

This usage will be applied to aircraft when those aircraft have been acquired by a company/military air arm purely for spares use (sometimes referred to as “non-fliers” or “donor” airframes).

This new usage will always be applied to aircraft that are in storage, and would typically be followed by a retirement event.

This new usage will initially only be applied on our business aviation, helicopter and military datasets, as well as military operated examples of types in our commercial dataset.

Viewing recently stored aircraft

The recent Covid-19 (Coronavirus) pandemic has caused significant numbers of the world’s aircraft to be moved from ‘In Service’ to ‘Storage’. Our fleet research team are busy monitoring the situation and making status changes to individual aircraft with the help of evidence from flight tracking data. Information can be found here which describes the methodology. To see daily updates, please visit here. Continue reading “”
