This month's topic is fatigue, especially pilot fatigue, and how to address it. We discuss the Audit Findings relating to fatigue and have included some case studies of the problem, but also some valuable research and solutions involving Fatigue Risk Management Systems (FRMS).
In other news, there is a new Global Helicopter Flight Data Monitoring (HFDM) Steering Group in the process of being formed, and some tips on the use of Non-Towered airports from NASA's Aviation Safety Reporting System - a USA perspective.

Finding 4 - Fatigue
National regulatory systems define the parameters for flight & duty times; in turn the AOC holder is responsible for rostering aircrew within these defined parameters. Hypothetically the final line of defense is the crew member who is usually given a documented (Flight Operations Manual) right of refusal if he or she considers themselves to be too fatigued to fly.
The 'right of refusal' is the selected audit finding topic for this Newsletter, as global audit processes have revealed an insidious and potentially catastrophic double-bind situation that we are all aware of but powerless to control.
It relates to some organisations' tacit or otherwise expectation that aircrew will not decline a flight even if fatigued, due to commercial pressures often linked to financial stress - this in turn compromises the aircrew member, as all too often their job is in jeopardy.
It is common knowledge that aircrew can be fatigued beyond safe limits even though they are within statutory flight & duty time limits.
The solution to this problem is complex as it is dependent upon a combination of regulatory requirements, with integrity and self-discipline as critical core components.
An established 'Confidential Reporting System' is an important factor in solving this global problem.

Stress and fatigue in aviation on the increase says Turkish researcher|
Dr Ellen Rosskam
Increasing demands, precarious work and a lack of financial security
have made civil aviation workers more vulnerable to stress and fatigue.
That was the message put forward recently by a researcher looking into
stress and fatigue as part of an International Transport Federation (ITF) study.
Speaking at a public meeting in Istanbul, Turkey, on 29 April hosted
by the Turkish ITF-affiliated aviation union Hava-Is, Dr Ellen Rosskam
lead researcher on the ITF global stress and fatigue study, addressed
pilots, cabin crew, ground staff, as well as airline representatives.
Rosskam explained why civil aviation workers, airlines and civil
aviation authorities should be concerned about increased stress and
fatigue levels and outlined responses received from ITF civil aviation
affiliates during her research. She said:
"According to almost 90 per
cent of aviation workers, jobs are getting more and more demanding. And
an increase in precarious work means more job stress. Those had been
coupled with decreases in social and economic security.

FAA Told to Address Crew Fatigue in Aviation|
Friday June 13, 2008
After the crew of a commercial aircraft apparently went to sleep at the
wheel and flew right over their destination airport, the National
Transportation Safety Board (NTSB) has recommended that the Federal
Aviation Administration (FAA) take steps to "address" the effects of
human fatigue in commercial aviation.
The NTSB urged the FAA to adopt regulations
requiring airlines to establish fatigue management systems designed to
increase the sleep time and quality of aircrews between flights, improve
crew alertness, mitigate performance errors, and prevent incidents and
In making their recommendation, the Board cited four fatigue-related
incidents occurring since 2004, one resulting in the deaths of both
pilots and 11 passengers.
Perhaps the most bizarre incident took place on Feb. 13, 2008, when Go!
flight 1002, operated by Mesa Airlines flew beyond its destination
airport, General Lyman Field, Hilo, Hawaii. For over 18 minutes air
traffic controllers at General Lyman Field tried without response to
contact the Go! crew, as the plane continued over Maui, the big island
of Hawaii and continued flying southeast over the Pacific Ocean. After
flying 26 miles beyond the airport, the crew responded and returned to
land at General Lyman Field. There were no injuries, probably just a lot
of embarrassment and extensive discussion with the FAA.
"Addressing this safety related measure is long overdue,
" said NTSB
Chairman Mark V. Rosenker in a press release
"We must and can correct this serious concern
." Let's all hope Chairman
Rosenker is correct.

Clemson professor receives national award for research on pilot fatigue|
A Clemson University professor's work to identify fatigue
and other human factors that lead to airplane accidents has earned him
the top award from the Aerospace Human Factors Association.Scott Shappell
, an industrial engineering professor, has received the
2010 Henry L. Taylor Founder's Award for outstanding contributions in
the field of aerospace human factors.
"Scott Shappell is a well-known human-factors professional who has
made significant contributions to the field," the association wrote in
presenting the award. "In addition to his early work on fatigue and
shift work, he is probably best known for his research in the areas of
human error, human-factors safety-management systems and fatigue effects
Shappell is co-developer of two important tools, the Human Factors
Analysis and Classification System (HFACS)
and Human Factors
, that are used to identify and prevent human factors
associated with accidents in high-risk industries such as aviation,
mining, rail, energy and medicine.

FRMS case study - easyJet|
Airlines launch fatigue risk management forum|
A group of airlines working with UK research company Qinetiq has set up a fatigue risk management forum to help the industry share best practice in controlling the dangers of pilot, cabin crew and engineer fatigue.
The International Civil Aviation Organisation has already ruled that
fatigue risk management systems (FRMS) should become standard in the
industry - over and above flight time limitations - and the European
Aviation Safety Agency is preparing to mandate FRMS as a part of every
airline's safety management system (SMS).
At Qinetiq's main base
in Farnborough, UK, delegates from 52 organisations all over the world
met to agree arrangements for launching the Fatigue and Risk Management
Forum. On 8 May they unanimously voted the organisation into existence.
The main airline players involved in setting up the forum are Air
New Zealand, EasyJet, Delta Air Lines and Virgin
Atlantic, but many more carriers sent representatives, as did
regulators from Australia, Europe, New Zealand and the UK.
Forum members have agreed to meet again in a year, (May 2010) by which time the
website should have assumed its basic shape.

Global Helicopter Flight Data Monitoring Steering Group Formed|
VANCOUVER, Canada (30 April 2010) Driven by a desire to increase helicopter safety by promoting best practice and cooperation in the design, support and operation of Helicopter Flight Data Monitoring (HFDM)
, a new organization has formed to bring all aspects of the industry together the Global Helicopter Flight Data Monitoring Steering Group. The Global HFDM Steering Group
was formed following the CHC Safety & Quality Summit held in Vancouver, Canada at the end of March.
Bringing together more than 70 people representing 48 organisations from across the globe, the Steering Group seeks to make HFDM as accessible as possible to all operators both large and small, by sharing information with the intent of making HFDM easy for operators to implement. The wide adoption of HFDM has been recognized as a key initiative by the International Helicopter Safety Team, formed in 2005 with a vision of reducing the rate of civil helicopter accidents by 80% within 10 years.
The Global HFDM Steering Group will publish information on its website at www.HFDM.org
which is expected to be ready in the near future; it will also be linked to the IHST website www.IHST.org
, which will host information in the interim.

Safe Operations at Non-Towered Airports|
Sedona Non-Towered Airport
The key to communicating at an airport without an
operating Control Tower is selection of the correct common frequency
for airport advisories while operating to or from the airport. CTAF,
which stands for Common Traffic Advisory Frequency, is designated for
Use of the correct CTAF, combined with visual alertness
and application of recommended operating practices, will enhance safety
of flight during non-Towered operations.
April's Callback focuses on ASRS non-Towered airport
incidents that emphasize the following themes:
Communication - Monitoring CTAF and
use of the radio to report position and intentions.
Traffic Mix - Being aware that
straight-in IFR traffic to a non-Towered field may conflict with
patterns for VFR traffic, especially in reduced visibility conditions
(broken or overcast ceilings, haze, etc.).
Avoidance - Practicing see-and-avoid procedures
and visually checking the final approach course before takeoff or
Use of the correct CTAF and current charts and flight information.
