Our primary aviation and design goal is to build aircraft that are a pleasure to fly, yet forgiving and safe, while offering maximum protection in Aviation Safety in case of an accident. To accomplish this we invest in two key safety strategies, Active and Passive Safety. Diamond Aircraft Safety and Design.
Aviation safety is a term encompassing the theory, investigation, and categorization of flight failures, and the prevention of such failures through regulation, education, and training. It can also be applied in the context of campaigns that inform the public as to the safety of air travel.
In the United States
During the 1920s, the first laws covering aviation safety were passed in the USA to regulate civil aviation. Of particular significance was the Air Commerce Act (1926) which required pilots and aircraft to be examined and licensed, for accidents to be properly investigated, and for the establishment of safety rules and navigation aids, under the Aeronautics Branch of the United States Department of Commerce.
Despite this, in 1926 and 1927 there were a total of 24 fatal commercial airline crashes, a further 16 in 1928, and 51 in 1929 (killing 61 people), which remains the worst year on record at an accident rate of about 1 for every 1,000,000 miles (1,600,000 km) flown. Based on the current numbers flying, this would equate to 7,000 fatal incidents per year.
The fatal incident rate has declined steadily ever since, and since 1997 the number of fatal air accidents has been no more than 1 for every 2,000,000,000 person-miles flown (e.g., 100 people flying a plane for 1,000 miles (1,600 km) counts as 100,000 person-miles, making it comparable with methods of transportation with different numbers of passengers, such as one person driving an automobile for 100,000 miles (160,000 km), which is also 100,000 person-miles), and thus one of the safest modes of transportation when measured by distance traveled.
The World Bank has published the reliable data of the frequency of passengers carried by Air Transport in the Year 2012 obtained from the International Civil Aviation Organization (ICAO). The United States of America has the largest number of Commercial Air Transport Passengers. 756,617,000 cf. China the next largest with 318,475,924. The United States had an International Flight frequency of 9,560,451 in 2012. The Civil Aviation Authority, JAR and EASA have published that there is a fatal accident ratio of one per million flights. The main cause is Pilot in Command error.
Between 1990–2006, there were 1441 commuter and air taxi crashes in the U.S. of which 373 (26%) were fatal, resulting in 1063 deaths (142 occupational pilot deaths). A disproportionate number of all U.S. aircraft crashes occur in Alaska, largely as a result of severe weather conditions. Alaska accounted for 513 (36%) of the total U.S. crashes.
Another aspect of aviation safety is protection from attack currently known as Security (as the ISO definition of aviation safety encompasses non-intentional (safety_safety) and intentional (safety_security) causes of harm or property damage). The terrorist attacks of 2001 are not counted as accidents. However, even if they were counted as accidents they would have added about 2 deaths per 2,000,000,000 person-miles. Two months later, American Airlines Flight 587 crashed in New York City, killing 256 people including 5 on the ground, causing 2001 to show a very high fatality rate. Even so, the rate that year including the attacks (estimated here to be about 4 deaths per 1,000,000,000 person-miles), is safe compared to some other forms of transport when measured by distance traveled.
Aviation Safety has improved from better aircraft design, engineering and maintenance, the evolution of navigation aids, and safety protocols and procedures. It is often reported that air travel is the safest in terms of deaths per passenger mile. The National Transportation Safety Board (2006) reports 1.3 deaths per hundred million vehicle miles for travel by car, and 1.7 deaths per hundred million vehicle miles for travel by air. However, airplanes often have hundreds of passengers, unlike road vehicles. The number of deaths per passenger mile on commercial airlines in the United States between 1995 and 2000 is about 3 deaths per 10 billion passenger miles.
From Diamond Aircraft: The best accident protection is to avoid them in the first place. Active Aviation Safety features and characteristics help do just that. Active Aviation Safety refers to all the features and characteristics of an aircraft that help pilots avoid an accident. These include docile handling characteristics, continued controllability through a stall, positive stability, high crosswind capability, excellent runway and climb performance, comfortable pilot workload, superior visibility, structural integrity under flight loads, critical system redundancies, reliable power and the many features that a modern integrated glass cockpit and digital autopilot offer. Beyond that, active aviation safety includes the matching of an aircraft design to its intended mission and pilot capability. Our single engine piston models are especially docile and well suited for expert and novice pilots alike. Our high performance aircraft offer ice protection and twin engine aviation safety, yet are easy to fly with simple single lever power controls.
