D  Characteristics and traffic assumptions for air ground air communicationsWord‑p. 97

The mission critical air ground air communications will be used as described below.

D.1  EnvironmentWord‑p. 97

Helicopters are used for rescue and providing reconnaissance information to support events/incidents in rural (including mountains) environments and urban environments. Helicopters are also used for rescue and providing reconnaissance support for events/incidents in the ocean within a limited range of land or ship.
Planes are often used in rural (including forests and mountains) environment, but they can also be used in and near urban areas.

D.2  AltitudesWord‑p. 97

Helicopters have an altitude of 1.500 ft in general but in mountains it goes up to 15.000 ft.
Planes have an altitude between 2.000 ft and 15.000 ft.
The system will have to operate from 500 ft above ground level/above the sea with service continuity between ground communications and air ground air communications.

D.3  Maximum speed and mobilityWord‑p. 97

Helicopters are moving at a speed of 250 km/h, planes are moving at 450 km/h. The ascent and descent speed are up to 1.000 ft per minute.

D.4  Traffic assumptionsWord‑p. 97

For a region of 90.000 km2, a minimum of 18 communications per regions are supported with at least 6 simultaneous communications for helicopters and at least 6 simultaneous communications for planes.
