Terrain and obstacle conflict is the second priority key risk area for helicopter offshore operations (HOFO), although equipment that is now fitted to helicopters that conduct these operations will significantly mitigate the risk of this outcome. Obstacle collisions is the second most common accident outcome in the helicopter commercial air transport (CAT) domain. This highlights themchallenges of helicopter emergency medical service (HEMS) operations and their limited selection and planning for landing sites. Terrain and obstacle conflict is the most common risk for specialised operations (SPO).
This RMT intends to mitigate these risks by establishing the conditions to install and use helicopter terrain awareness and warning systems (HTAWSs) and other CFIT prevention means
