You can still provide requirements for ISOBAR prototype service functionalities. Please use the ISOBAR Demo Engine to have an overview of some of the target functionalities envisaged for the final ISOBAR service. The Demo will guide you through three snapshots of the ATFCM process done at Network Manager at D-1 (being D-0 the day of operations). The easiest way of providing your inputs is to download the Excel file “ISOBAR Requirements-Gaming Questions” and fulfil the desired cells for each snapshot of the process. Once fulfilled, you can send it by email to firstname.lastname@example.org. You can also send us your views in text via the same channel. Please include in the email your professional affiliation and contact details.
