Revision Session Flashcards
What is ALARP?
As Low As Reasonably Practicable
The cost of further reduction is “grossly disproportionate” to the benefits of risk reduction
What is Air Safety?
The state of freedom from unacceptable risk of injury to personal, or damage, throughout the life cycle of military Air Systems
What is Flight Safety?
The ability to operate in the air environment in the safest possible manner.
What is Air Worthiness?
The ability of an aircraft, airborne equipment or system to be operated in the air and on the ground without any significant risk to aircrew, ground crew, passengers or third parties.
Describe human factors.
Relates to people in their working environment and their relationship with:
Equipment
Procedures
The environment
Other people
What makes up long-term memory?
Semantic memory
Motor memory/mechanical skills
Episodic memory
What is CRM?
Crew Resource Management
The use of all skills and resources available to a crew to achieve the aims of the flight (i.e. safety, effectiveness and efficiency)
Why was CRM introduced?
To improve safety and, incidentally, the efficiency of aircraft operations.
Was found that anywhere between 50-70% of aircraft accidents were the result of Human Factors.
What is risk?
A measure of exposure to possible harm.
What is a hazard?
An intermediate state where there is the potential for harm.
Who are the Duty Holders and what is their responsibility?
Senior Duty Holder (4*)
Operating Duty Holder (2*)
Delivery Duty Holder
Actively manage air safety in their AoR.
Have a duty of care for the personnel under their command, those temporarily involved in aviation activities in their AoR and the wider public who may be affected by their operations.
What are FRC’s and what is their purpose?
Best practice drills for normal flight and emergencies.
Emergencies procedures section provides aircrew with a quick reference in the event of emergency.
What is meant by ‘Land As Soon As Possible’ for FW aircraft?
Land at the nearest airfield suitable for a safe landing but be prepared to force-land immediately if it becomes necessary.
What is meant by ‘Land As Soon As Practicable’ for FW aircraft?
Land at the nearest airfield where you can land safely and expect practical assistance for your aircraft type.
What is meant by ‘Land As Soon As Possible’ for RW aircraft?
Do not continue to fly for any longer than is necessary to accomplish a safe landing at the nearest site.
What is meant by ‘Land As Soon As Practicable’ for RW aircraft?
Land at the nearest aviation location or at a suitable site selected for convenience.
What is meant by ‘Land Immediately’ for RW aircraft?
Land at once even if this means ditching or landing in the trees.
The consequences of continuing to fly are more than likely more harmful than landing at a site that is normally considered unsuitable.
What is the swiss cheese model?
Incidents are often the result of a series of events. Breaking one link in the chain of events may stop the incident.
Cheeses are layers of defence, but no defence is perfect and each has a hole.
Any layer of defence can prevent an incident, but when if the holes all line up, then the likelihood of an incident occurring will increase.
When these holes line up it can lead to an incident/accident.
Normally never just one factor, but multiple occurrences leading to an accident.
What is the SHELL model?
Way of looking at where threats and mistakes lie, specifically at the interfaces between the different elements.
There is rarely a single cause for an accident, but an interaction between the different elements.
What are the elements of the SHELL model?
Software
Hardware
Environment
Liveware (teams)
Liveware (people)
What is Heinrich’s triangle?
States that there are many (often unreported) near misses in relation to the number of reportable incidents and accidents.
What is FOD?
Foreign Object Debris
Can lead to…
Foreign Object Damage
What is a Risk to Life Matrix?
Likelihood up the side axis
Severity along the top axis
Enables safety risks to be controlled at an acceptable level.
What is a DASOR?
Defence Air Safety Occurrence Report
What is the DAEMS?
Defence Aviation Error Management System
What is the MAA and it’s purpose?
Military Aviation Authority
A tri-service regulatory authority.
Responsible for all aspects of Air Safety across DEFENCE.
