world. By region of the world the civilian air transport accident rate (accidents per million
departures) is:
Africa 10.7
Asia & Pacific Islands 2.6
China 4.2
Japan 0.8
Europe 0.8
Latin America and Caribbean 4.5
Middle East 2.0
Oceania 0.3
USA & Canada 0.5
Data indicating the primary factor causing accidents is found in Figure 2.9, in this case
comparing causal factors between the U.S./Canada and Latin America. ATC is cited for
hull loss accidents between 1982 and 1992 in 19% of the cases in the U.S. and 14% of
Latin American hull loss accidents.

The last issue of the system performance factors is efficiency. We define efficiency as the
cost, or degree to which the current or future system penalizes the airplane operations,
versus a minimal (or optimal) cost. Factors which are contained in the efficiency costs
include: route circuitry, other procedural restrictions such as special use airspace
prohibitions, and flight delay, often due to inadequate airport or airspace capacity. An
ATA study was performed on the base year of 1993 to examine these infrastructurerelated
costs. The ATA assessment was that the current system operation costs $4 billion
annually over best operation. United Airline estimated they incur costs of $670 million
annually (Cotton, 1994). These costs will increase with traffic loads, and that the delay-
