Aeronautical Data Chain

A key driver for the transition from AIS to AIM is the need to achieve an uninterrupted aeronautical data chain with no loss or corruption in information, in a pre-defined format and with guaranteed accuracy and integrity. The aeronautical data chain is defined as “a series of interrelated links wherein each link provides a function that facilitates the origination, transmission and use of aeronautical data for a specific purpose”.

Obstacles penetrating the Annexure 14 surfaces (specifically in the Approach Funnel and IHS ) may affect air safety if not properly controlled. TOD is required for monitoring and surveillance of obstacles for ensuring flight safety. An accurate digital database of Obstacles around the Aerodrome needs to be created and updated at regular intervals as per DGCA Guidelines.
