HE9 Automation and Flight Path Management

28 September 2015 – This document identifies current best practice on automation and flight path management. Over the years helicopter manufacturers have used more automation to assist crews and reduce manual flying workload. The rapid advances in technology have given rise to significant capabilities. Automation has contributed substantially to the sustained improvement of flight safety. Automation increases the timeliness and precision of routine procedures reducing the opportunity for errors and the associated risks to the safety of the flight. The helicopter community has however experienced incidents and accidents where automation and complex flight displays have been significant factors. This leaflet reviews the basics of automation and provides a list of principles for optimal use of automation and flight path management.

EHEST Publishes Helicopter Instructor Guide

2 July 2015 – One if the important ingredients for flight safety is a properly resourced training sector. Some of those resources can be quite fundamental. For example, an important contribution to training is for flight instructors to have available to them a basic guide to flying training. In response to this need, EHEST contacted the Australian Civil Aviation Safety Authority (CASA) which has developed a flying instructors’ manual incorporating extensive feedback from the helicopter training community. CASA has kindly made this manual available to EHEST for dissemination. Some changes have been incorporated to reflect European terminology and syllabus contents. The EHEST Helicopter Flight Instructor Manual is comprehensive and fully illustrated. Part 1 addresses Principles and Methods of Instruction and Part 2 provides Ground and Air Instruction Exercises. It will be a great resource for the European flight instructors, who may freely download and use this manual.

Users are encouraged to provide feedback to ensure that any further revisions meet industry needs. You can email your feedback to us at: ehest@easa.europe.eu.

HE 8 – The Principles of Threat and Error Management (TEM) for Helicopter Pilots, Instructors and Training Organisations

12 December 2014 – The European Helicopter Safety Team (EHEST) today published a new safety promotion leaflet on  the Principles of Threat and Error Management (TEM) for Helicopter Pilots, Instructors and Training Organisations (HE 8). Data analysis  confirms that a continuing significant number of helicopter accidents occur due to poor decision making and human performance made both prior and during flight. The aim of this leaflet is to introduce and illustrate the concept of TEM to flight crews and training organisations. Leaflet HE 8 is part of a series of safety leaflets and publications aimed at sharing good practices, which are freely available on the Training and Safety Promotion section of the EHEST website.

HE 7 – Techniques for Helicopter Operations in Hilly and Mountainous Terrain

13 May 2014 – The European Helicopter Safety Team (EHEST) today published a new safety promotion leaflet on techniques for helicopter operations in hilly and mountainous terrain. The leaflet aims to help pilots and instructors understand basic principles, threats, errors and possible undesirable aircraft states when flying in mountainous terrain. Developed in partnership with major stakeholders, the leaflet also provides guidance to manage the risks associated with these operations.  Click here to download the leaflet.

Safety Promotion Leaflet on Using Advanced Navigation Technology Safely

The European General Aviation Safety Team (EGAST) published a new Safety Promotion Leaflet on Using Advanced Navigation Technology Safely. The market for onboard navigation technology is evolving quickly. The immediate potential safety benefits are numerous including reduced workload and unprecedented information to enhance situational awareness but the technology may also come with hidden risks including overreliance on systems and distraction. This Leaflet, which is also of relevance for the helicopter community, intends to raise awareness on potential traps and share good practices for better and safer use of advanced technology for navigation in day VFR.

HE 6 – Advantages of simulators in Helicopter Flight Training

9 July 2013 - The EHEST publishes today a new Safety promotion leaflet on the advantages of simulators in Helicopter Flight Training. The purpose of this leaflet is to highlight the various helicopter flight simulation training devices available and to also review the additional training and safety benefits related to recent technological and regulatory developments.

HE5 Training Leaflet – Risk management in training

March 2013 – EHEST published their latest Safety Leaflet  “HE5 – Risk Management in Training for Helicopter Pilots and Instructors”. The document was developed in partnership with major stakeholders and provides tools and methods to improve risk management in training. Training for autorotation is used as a practical example to illustrate the process.

Safety Management Toolkit – August 2012

2 August 2012 - EHEST released a comprehensive Safety Management Toolkit developed with consideration to EU rules on Air Operations (Annex III, Part ORO Subpart GEN Section II Management System) which are expected be finalised later this year. The Toolkit was designed for Complex Operators and is particularly useful for those with limited experience of Safety Management Systems (SMS). It consists of a Safety Management Manual (SMM), an Emergency Response Plan (ERP) and a Safety Management Database User Guide.

The SMM is a sample manual designed to assist operators in creating their own manuals, which must be adapted to reflect individual needs, nature of operations and procedures. Since having a ERP will be required under future rules, the EHEST response plan in this Toolkit aims to help organisation to respond in the case of accidents, serious incidents or any event triggering a crisis.

Finally, the Safety Management Database User Guide provides example registers of typical helicopter hazards and risks in Commercial Air Transport (CAT) operations, a unique feature provided by the EHEST for safety management purposes.

HE4 Training Leaflet – Single Pilot Decision Making

June 2012: Research into the human factors related to aircraft accidents and incidents has highlighted Decision Making as a crucial element. Pilots intend to fly safely, but they sometimes make errors. It has been observed that the majority of fatal crashes are attributable to decision errors rather than to perceptual or execution errors.

HE4_Single Pilot Decision Making v1

While we cannot eliminate human error, a thorough understanding of human factors principles can lead to appropriate strategies, means and practical tools to prevent most errors, better detect and manage them, and mitigate their adverse impact on aviation safety.

This leaflet is looking at:

  • Human Factors Affecting Decision Making,
  • Decision Making,
  • Decision Error Factors,
  • Decision Making Models.

This leaflet is part of a series of safety leaflets and publications aimed at sharing good practices. These leaflets are accompanied by web-based training materials, including videos, which are freely available on the Training and Safety Promotion section of the EHEST website

HE3 Helicopter Off Airfield Landing Site Operations

Jan 2012 - The helicopters ability to approach, manoeuvre, land and take-off from an off airfield Landing Site or unprepared Landing Site is one of the most important aspects of helicopters operations.

The various landing sites such as hotels, golf courses, sporting venues, etc can vary in their dimensions, approaches, hazards, elevation, and location, the same basic principles should be employed.

Landing sites that are remote from an airfield offer various challenges to the pilot and consequently have resulted in a significant number of accidents. Unlike at an airfield there is generally, little or no assistance in the assessment of wind, guidance on appropriate approach directions or information on other traffic. Hazards not normally experienced at an airfield such as wires, obstructions, uneven landing ground, trees, Foreign Object Damage, livestock and pedestrians are quite likely to be found and require a heightened degree of situational awareness by the pilot who needs to expect the unexpected!

The brochure HE3 was developped by the EHEST Team and covers the:

  • Planning and Preparation
  • Landing Site Identification
  • Landing Site Recce
  • Types of Approach
  • Manoeuvring in the LS
  • Departure
  • Pilot Errors
