Loss of Control – In Flight

LOC-I chart.002-003

Loss of control in flight (LOC-I) is a leading cause of fatalities in the commercial aviation industry. A variety of reasons exist for airplane upsets:

Environmental
Poor visibility. Icing conditions. Some pilots are not trained or equipped to fly at night and find themselves having to continue flying to reach an airport after it gets dark. An example of this John Kennedy’s plane that was lost at night in the ocean near Marthar’s Vineyard.
Airplane system malfunction or misinterpretation
This can be a failure of a part during normal service. Most aircraft systems have built-in redundancy so that a failure of one part will not create an unsafe condition. Some mechanical failures is due to bad maintenance; such as someone forgetting to tighten a bolt.
Pilot induced
This can vary from not paying attention to his instruments or watching for other a/c. People are only human so many accidents are attributed to poor judegment of the pilot. For example; the weather may be getting bad but the pilot chooses to fly into the storm. Larger passenger airliners have 2 or more flight crew which helps eliminate some human errors.

No single reason is statistically significant, and eliminating one reason will not simply reduce the number of LOC-I accidents and fatalities.
