  • Updates over the Christmas period

    From next week (WC 23rd) the 25 members of the UK based data team will be taking a well earned break to enjoy the festive period.

    During this time there will be limited fleet data updates, but rest assured, we will be back in early January to catch up with all the changes.

    We wish all Cirium customers a very merry Christmas and a happy New Year!

    Best Wishes

  • The way we calculate the age of an aircraft is going to change

    Due to the recent change to the definiton of Build Date, we are changing our definition of age.

    Currently

    Age is calculated as the duration since the date of the aircraft’s first flight, if we have no recorded first flight, then we use the delivery date.

    New

    Age will be calculated as the duration since the Build Date. Build Date is taken as the delivery date, unless the aircraft’s first flight was more than 12 months prior to delivery date, in this scenario Build Date is taken as the first flight date.

    These changes will take effect from 20th January 2020.

    For more information on how we determine the Build Date, please see the article on the Cirium Thought Cloud.
