Significant progress has been made by these avionics producers with advanced databases, displays and alerting systems.
FAA’s recent rule making announcements mandated some new equipment and higher levels of training aimed at stemming the increased accident and fatality rates. Today there are more uses and increased value in helicopter operations, which influence almost every aspect of society. And the dangers associated with operations down low for helicopters has led to a need to do something different. FAA notes that “These pilots fly year-round in rural and urban settings, over mountainous and nonmountainous terrain, during the day and during the night, and in conditions where visibility is good and in conditions here it is not. They must often land at unfamiliar, remote, or unimproved sites with hazards like trees, buildings, towers, wires, and uneven terrain.”
Another aspect of what is occurring comes innocently from many that hire helicopters with the expectation of precision anywhere, regardless of the environment or terrain. Today the result is a tempo and type of helicopter operations that have taken older machines and instrumentation past their limits. The FAA poignantly added in a recent rule making document that, “Of the most significant reasons for an accident in a helicopter, wire and obstacle strikes are the greatest threats, followed by CFIT—controlled flight into terrain—at night.“
