CAN SIGHTING REPORTS INDICATE COLLISION RISK OVER THE NORTH ATLANTIC.

It was suggested that by collecting sighting reports from North Atlantic air traffic and cross-checking them against air traffic control records it would be possible to identify some reports as due to aircraft straying from their cleared track, and that changes in the rate of such 'validated�...

Description
Summary:It was suggested that by collecting sighting reports from North Atlantic air traffic and cross-checking them against air traffic control records it would be possible to identify some reports as due to aircraft straying from their cleared track, and that changes in the rate of such 'validated' reports could be used to detect changes in lateral collision risk, i.e. in the risk which is due to loss of lateral separation. The object of the study is to examine whether the number of validated sightings is large enough to enable an important change in collision risk to be detected within a reasonable period of time. The answer appears to be no. (Author)
