  C-29. Fielding of the Expanded Air track Sensor Interface will update future TAIS shelters with modernized
  air track equipment and capabilities. Expanded Air track Sensor Interface is a government owned and
  developed air track fusion engine that will provide the ATC common air picture, access to ATC active and
  passive sensors, and will replace the commercial air defense systems integrator in all TAIS shelters. In TAIS
  command post shelters, the Expanded Air track Sensor Interface link management and track fusion capability
  will be retained as a backup to the AMD shelter air defense systems integrator and suite of systems that are
  currently providing command post air track inputs to enable development of the air picture.
  AIR AND MISSILE DEFENSE WORKSTATION
  C-30. The AMD workstation provides a common AMD staff planning and execution tool. It enables
  collaborative AMD integration with intelligence preparation of the battlefield through development of threat
  analysis and sensor/shooter employment. The workstation also provides an AMD gateway to a mission
  command system and AMD interface to joint and multinational systems. For commanders, the AMD
  workstation provides a visual three dimensional airspace picture with near-real-time air tracks. For
  ADAM/BAEs, the AMD workstation enables them to parse and graphically display the airspace control
  order, airspace coordinating measures, airspace control overlay, and unit airspace plan. The AMD
  workstation also enables ADAM/BAEs to leverage the integrated enemy target and friendly aircraft data for
  airspace clearance. The workstation enables not only integrated Army AMD and aviation planning but also
  near-real-time airspace control.
  AIRSPACE CONTROL WITH A DEGRADED NETWORK
  C-31. While networks and applications greatly enhance airspace control, commanders can exercise airspace
  control in a degraded network environment. However, in a degraded network environment, controlling
  airspace is based on preplanned airspace coordinating measures with limited capability to assess airspace
  control effectiveness or make adjustments during execution. The nature of an operational environment,
  combined with the broad range of threats, makes it likely that Army forces will have to operate under
  degraded conditions and networks. While Army air-ground system and airspace information systems are not
  envisioned as a primary target, they will be degraded as a result of attacks against key enabling networks and
  nodes.
  C-32. For airspace elements, degraded network operations potentially cause loss of air picture or air-ground
  communications, brigade CP connectivity, or digital systems in the CP. Loss of air picture or air-ground
  communications will force airspace elements to resort to 100 percent procedural control. Loss of brigade CP
  connectivity affects connectivity to higher headquarters CPs and joint airspace control nodes. In this case,
  airspace elements continue to digitally plan airspace use, download airspace coordinating measure requests
  (known as ACMREQs) to a disk, and physically transport it to an adjacent brigade that has connectivity or
  to a higher headquarters airspace element. Loss of digital systems in the CP occurs when the TAIS
  malfunctions. In this case, airspace elements can—with connectivity—client into another unit’s TAIS. Loss
  of connectivity forces airspace elements to update maps and overlays manually. Airspace element personnel
  need to retain skills and expertise to control airspace manually.
