  • A note on aircraft returning to service

    Just a quick update on the situation with our commercial fleet details as we continue to react to the latest COVID market outlook.

    Due to the ongoing uncertainty with this pandemic and air travel in particular, we have taken the decision to remove the “scheduled to return / enter service” event from all aircraft currently in storage, except for those where airlines have announced a planned return for their fleet or sub-fleets.

    As always, we will continue to review on a daily basis the latest flight status of fleets as well as reflecting the very latest announcements and press statements from the airlines as they re-shape their fleet plans.

    Customers will need to be mindful of the above change when using any future fleet date in Analyzer as the aircraft will now still show in storage in the coming years.

  • 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

  • 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

  • Passenger to Freight Usage Changes

    As the Covid-19 Pandemic continues to impact the Aviation industry and in particular commercial passenger services we are making some further adjustments to how we track the ongoing usage of aircraft.Continue reading

  • 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.

    Storage

    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.
