AUTOMATION
Automation
is the single most important advance in aviation Technologies and important for
risk management. Electronic
flight displays have made vast improvements in how
information is displayed and what information is available to the pilot. Pilots
can access onboard information electronically that includes databases
containing approach information, primary instrument display, and moving maps
that mirror sectional charts, or display modes that provide three-dimensional
views of upcoming terrain. More pilots now rely on
automated flight planning tools and electronic databases for flight planning
rather than planning the flight by the traditional methods of laying out charts,
drawing the course, identifying navigation points and using the pilot’s
operating handbook to figure out the weight and balance and performance
charts.No longer most of the aviation community believes automation has made
flying safer, but there is a fear that pilots fail to see that automation is a
double-edged sword. Pilots need to understand the advantages of automation
while being aware of its limitations. Experience has shown that automated systems
can make some errors more evident while sometimes hiding other errors or making
them less obvious.
COCKPIT AUTOMATION STUDY
Modern
aircraft are increasingly reliant on automation for safe and efficient
operation. However, Automation also has the potential to cause significant
incidents when misunderstood or mishandled. Furthermore, automation may result
in an aircraft developing an undesirable state from which it is difficult or
impossible to recover using traditional hand flying techniques.There are many
advantages and disadvantages in this situation; increases passenger comfort , improved
flight path control and reduced weather minima,systems monitoring displays
coupled with diagnostic assistance systems (ECAM/EICAS) support enhanced
pilots’ and maintenance staff’s understanding of aircraft system states.
However, when faced with a complex failure event, such as Airbus 380 engine
break-up, the normally simple to understand’ failure information can swamp the
crew and either hinder diagnosis or distract the crew from the principle task
of fly the aircraft ; automation can relieve pilots from repetitive or
non-rewarding tasks for which humans are less suited, though it invariably
changes the pilots’ active involvement in operating the aircraft into a
monitoring role, which humans are particularly poor at doing effectively or for
long periods.Good automation reduces workload, frees attentional resources to
focus on other tasks but the need to ‘manage’ the automation, particularly when
involving data entry or retrieval through a key-pad, places addiiotnal tasks on
the pilot that can also increase pilot workload. In contrast, poor automation
can reduce the operators’ situational awareness and create significant workload
challenges when systems fail.
Flight
Crew - Automation Interaction Issues
Basic
manual and cognitive flying skills can decline because of lack of practice and
feel for the aircraft can deteriorate. This is exacerbated if operators
actively discourage flight crew from manual flying or limit the manual modes
they may use – e.g. prohibiting manual flying with Auto-Throttle disengaged;unexpected
automation behaviour: un-commanded disengagement caused by a system failure
resulting in mode reversion or inappropriate mode engagement by the pilot may
lead to adverse consequences;pilots interacting with automation can be
distracted from flying the aircraft; selection of modes, annunciation of modes,
flight director commands may be given more importance than value of pitch,
power, roll and yaw and so distract the flight/crew pilots from flying the
aircraft; flight crews may spend too much time trying to understand the origin,
conditions, or causes of an alarm or of multiple alarms, which may distract
them from other priority tasks and from flying the aircraft; short notice
changes by ATC requiring reprogramming of a departure or landing runway are
potentially hazardous due to the possibility of incorrect data entry and
crosschecking in a time critical situation.
Improvement Paths
Improve
basic airmanship and manual flying skills of pilots; improve recurrent training
and testing practices with regard to automation management; improve the Multi
Crew Cooperation (MCC) concept and training (instruction and testing) practices
to better address automation management; improve the Competence Based Training
(CBT) and Evidence Based Training (EBT) approaches to better address automation
management; develop automation policies specific to aircraft types and variants
to account for differences regarding automation and flight path management; improve
the Multi-crew Pilot Licence (MPL) programme to better address automation
management; manufacturers are to publish automation philosophies and policies,
generic and specific to aircraft types and variants, for communication to the
training (instructors and trainees) and operations communities.
ENHANCED SITUATIONAL AWARENESS
Enhanced situational awareness is
integral to risk management and response evaluation. Dynamic systems that
incorporate both hard and soft data sources allow for comprehensive situational
frameworks which can supplement physical models with conceptual notions of
risk. The processing of widely available semi-structured textual data sources
can produce soft information that is readily consumable by such a framework.
AUTOPILOT SYSTEMS
An autopilot is a system used to
control the trajectory of a vehicle without constant 'hands-on' control by a
human operator being required. Autopilots do not replace a human operator, but
assist them in controlling the vehicle, allowing them to focus on broader
aspects of operation, such as monitoring the trajectory, weather and systems.Autopilots
are used in aircraft, boats (known as self-steering gear), spacecraft,
missiles, and others. Autopilots have evolved significantly over time, from
early autopilots that merely held an attitude to modern autopilots capable of
performing automated landings under the supervision of a pilot.
Familiarity
As previously discussed, pilot
familiarity with all equipment is critical in optimizing both safety and
efficiency. A pilot’s being unfamiliar with any aircraft system will add to
workload
and may contribute to a loss of
situational awareness.
Respect
For Onboard Systems
Automation can assist the pilot
in many ways, but a thorough understanding of the system(s) in use is essential
to gaining the benefits it can offer. Understanding leads to respect, which
is achieved through discipline
and the mastery of the onboard systems.
Reinforcement of Onboard Suites
The use of an electronic flight
display (EFD) may not seem intuitive, but competency becomes better with
understanding and practice. Computer-based software and incremental
training help the pilot become
comfortable with the onboard suites.
Getting Beyond Rote Workmanship
The key to working effectively
with automation is getting beyond the sequential process of executing an
action. If a pilot has to analyze what key to push next, or always uses the
same sequence of keystrokes when others are available, he or she may be trapped
in a rote process. This
mechanical process indicates a shallow understanding of the system.
Understand the Platform
Contrary to popular belief,
flight in aircraft equipped with different electronic management suites
requires the same attention as aircraft equipped with analog instrumentation and
a conventional suite of avionics.
FLIGHT
MANAGEMENT SKILLS
Automation
Management
Automation Management provides
the skills to properly manage an automated flight deck to increase level of
customer safety, passenger comfort and on time performance. Pilots will become
familiar with Auto Pilot, Flight Director, Flight Management Systems and other
associated equipment. Thus,
pilot skills for normal and emergency operations hinge not only on mechanical
manipulation of the stick and rudder, but also include the mental mastery.
Three key flight management skills are needed to fly the advanced avionics
safely: information, automation, and risk.
Information
Management
The management of risk data and
information is key to the success of any risk management effort regardless of
an organization's size or industry sector. Risk management information
systems/services (RMIS) are used to support expert advice and cost-effective
information management solutions around key processes such as:risk
identification and assessment , risk control , risk financing typically, RMIS
facilitates the consolidation of information related to insurance, such as
claims from multiple sources,property values, policy information, and exposure
information, into one system. Often, RMIS applies primarily to “casualty”
claims/loss data systems. Such casualty coverages include auto liability, auto
physical damage, workers' compensation, general liability and products
liability.
RMIS products are designed to
provide their insured organizations and their brokers with basic policy and
claim information via electronic access, and most recently, via the Internet.
This information is essential for managing individual claims, identifying
trends, marketing an insurance program, loss forecasting, actuarial studies and
internal loss data communication within a client organization. They may also
provide the tracking and management reporting capabilities to enable one to
monitor and control overall cost of risk in an efficient and cost-effective
manner.
Risk
Management
Risk management is the last of
the three flight management skills needed for mastery of the advanced avionics
aircraft. The enhanced situational awareness and automation capabilities
offered by a glass flight deck vastly expand its safety and utility, especially
for personal transportation use.At the same time, there is some risk that
lighter work loads could lead to complacency.In addition , It is important to
remember that EFDs do not replace basic flight knowledge and skills. They are a
tool for improving flight safety. Risk increases when the pilot believes the gadgets
compensate for lack of skill and knowledge.As a conclusion,pilot management of
risk is improved with practice andconsistent use of basic and practical risk
management tools.
Conclusion
Automation statistics is very
important to explain accident data situational and for awareness
autopilot system a subject that interests me a lot . You 've touched on a really beautiful location . If we look at the original pilot autopilot system he is doing lazy. also a case to be very careful. I would have you received when you stand idly pilot aircraft autopilot . They were in need to check carefully. meanwhile , you could share the photos but not so important . I am informed that I'm really reading your blog . You inform us about the pilot management capabilities. Thank you for the work .
YanıtlaSilAutomation is really important issue for aviation sector but most people do not care. so it is a good topic.Due to recent incidents involving glass cockpit aircraft, there is growing concern about cockpit automation and its potential effects on pilot performance. However, little is known about the nature and causes of problems that arise in pilot-automation interaction. Thank you.
YanıtlaSilThe size is perfect Murat, not too much detailed neither too much summarized. But I can't say the same thing for your summary. your work is well organized. I have to admit that I was not very familiar with your topic before reading but you managed to explain everything in a very clear english, that is something I apreciate about your work.

YanıtlaSilMurat, automation does not replace the pilot. For instance, unlike landings, take offs cannot be executed through automated systems. And there is always a need for the pilot in case of emergencies. However, I agree that automation provides us with more time to monitor the performance of the aircraft. With increased situational awareness, safety increases since this.gives the pilot better management of risks.

YanıtlaSilTo be frank, I have no idea about automation systems before I read your article. And I can easily say that I do not need further explanations. Although automation is consist of plenty technical terms, you did a nice job to organize the subject.
