Turbulence Education and Training Aid

The Turbulence Education and Training Aid was developed by an industry team consisting of participants from airlines, airplane manufacturers, and the FAA to provide a means for the reduction of injuries and damage caused by turbulence encounters. The training package consists of this document and an accompanying. Turbulence is the leading cause of injury in…… Continue Reading →

Volcanic Ash Avoidance

A commercial aircraft encounter with volcanic Ash can threaten safety of flight because of resulting conditions that can range from windshield pitting to loss of thrust in all engines. Developments in technology and communication networks have significantly decreased the probability of such an encounter in the last several years. Despite these developments, however, a 737-700…… Continue Reading →

Weather Conditions Associated with Jet Engine Power Loss and Damage due to Ingestion of Ice Particles

The aviation industry has now connected a number of jet engine power-loss and damage events to the ingestion of ice particles. Ice particle icing related jet engine power-loss and damage events are occurring during flights of large transport aircraft, commuter, and business jets. These events have only recently been recognized as occurring in regions of…… Continue Reading →

Wind Gradients and Turbulence

This document presents four events linked to meteorological phenomena, strong winds at altitude or convective movements associated with cumulonimbus. Although different in nature, these examples have some common points: the sudden deterioration of the conditions, late detection, sometimes inappropriate reactions, lack of information transfer within flight crews (PIREP). Since they are difficult to characterize in…… Continue Reading →
