Threat and Error Management (TEM) for Helicopter Operations

Here’s one for the helicopter community. An introduction to the principles of threat and error management with a particular focus on how it affects rotary wing operations.

In helicopter operations, the TEM model is particularly valuable due to the unique challenges and operational complexities involved. Helicopter pilots often face varied and dynamic environments, such as adverse weather conditions, confined landing zones, and low-altitude operations. The TEM model helps pilots anticipate, detect and manage threats, errors and Undesired Aircraft States (UAS, and keep margins of safety.

The Boeing aerospace safety timeline

The Aerospace Safety Timeline tool is an impactful way of visualising data and describes the history of innovation and development in aerospace.

It features significant aerospace events, accidents, investigations, innovations, and regulatory decisions that have shaped aerospace history, allowing you to view images, videos, and other details of significant events during your aerospace safety exploration.

Dramatic AW139 Accident at Houma: Effective CRM contributes to recovery from a latent defect

On 24 September 2022, a Leonardo AW139 of ERA Helicopters, was involved in a dramatic accident near Houma, Louisiana from which the two pilots and four passengers emerged uninjured. It was an outstanding example of how when faced with a complex and ambiguous emergency effective CRM can make the difference.

Faced with smoke in the cockpit, seized flight controls, and engines that would only output maximum power, the crew managed to work together to get the crippled aircraft back to the field by cycling the engines from flight to idle, and then achieved an engines off landing to the runway.

Military vs Civil: Does training background affect safety in helicopter pilots?

Until recently, there has been a lack of up-to-date empirical research exploring the impact of professional culture in aircrew. Now a recent study of helicopter pilots from the University of Aberdeen with the title “Does training background affect safety in helicopter pilots?” (Kaminska et al., 20231), suggests that we need to pay more attention to how the military-civil divide impacts CRM behaviours amongst mixed crews. What do the cultural differences embedded in the different ways these pilots have been trained mean to competency, operational effectiveness, and – ultimately – safety?
