Helicopter Air Ambulance Risk Tool. An integrated risk assessment tool that resides on the iPad and automates MANY of the routine tasks that are involved in risk assessment. HAART not only tracks all FAA and CAMTS requirements (duty time limits, rest periods, day/night landing, etc.) it automates weight and balance, landing sites and OCC communication. By giving easy access to company approved check lists, weather and direct OCC communication HAART not only improves chute times it makes the risk assessment a real tool instead of a hurdle.
