An open field may look like a suitable helicopter landing site on an aerial image. However, the image alone does not establish whether the ground meets the requirements of a particular aircraft.
Aircraft size, terrain gradient and surrounding structures all influence the assessment. For air ambulance operations, casualty evacuation (CASEVAC) and wider helicopter support, these factors can narrow the available landing options.
CRSL’s assessment tools use aircraft D-value, terrain and surrounding structures to identify potential landing areas and highlight locations that do not meet the selected assessment criteria.

The comparison shows how assessment adds information beyond the aerial image, helping crews understand potential landing options and constraints.
The assessment supports operational decision-making. The final landing decision remains with the pilot.
