Between which components with reference to the shell concept covers pilot ?

Question 101-14 : Liveware hardware liveware software liveware environment liveware liveware

.the shell model is a conceptual model of human factors that clarifies the scope of aviation human factors and assists in understanding the human factor relationships between aviation system resources/environment the flying subsystem and the human component in the aviation system the human subsystem.the shell model was first developed by edwards 1972 and later modified into a 'building block' structure by hawkins 1984 the model is named after the initial letters of its components software hardware environment liveware and places emphasis on the human being and human interfaces with other components of the aviation system . 1964.s = software procedures symbology etc .h = hardware machine .e = environment.l = liveware human.in the shell model the match or mismatch of the blocke interface is just as important as the characteristics of the blocks themselves a mismatch can be a source of human error.liveware hardware l h . interaction between human operator and machine. involves matching the physical features of the aircraft cockpit or equipment with the general characteristics of human users while considering the task or job to be performed .examples . designing passenger and crew seats to fit the sitting characteristics of the human body. designing cockpit displays and controls to match the sensory information processing and movement characteristics of human users while facilitating action sequencing minimising workload through location/layout and including safeguards for incorrect/inadvertent operation. mismatches at the l h interface may occur through . poorly designed equipment. inappropriate or missing operational material. badly located or coded instruments and control devices. warning systems that fail in alerting informational or guidance functions in abnormal situations etc . the old 3 pointer aircraft altimeter encouraged errors because it was very difficult for pilots to tell what information related to which pointer exemple 253 liveware - hardware.liveware - hardware.

The errors of a motor programme are ?

Question 101-18 : Action slip and environmental capture habituation habituation and error of commission action slip and confirmation bias confirmation error and error of commission

.motor programmes .if a task is performed often enough it may eventually become automatic and the required skills and actions are stored in long term memory these are known as motor programmes and are ingrained routines that have been established through practice .the use of a motor programme reduces the load on the central decision maker an often quoted example is that of driving a car at first each individual action such as gear changing is demanding but eventually the separate actions are combined into a motor programme and can be performed with little or no awareness these motor programmes allow us to carry out simultaneous activities such as having a conversation whilst driving. action slips as the name implies are the same as slips i e an action not carried out as intended .the example given below may consist of a pilot intending to key in fl110 into the fms but keying in fl100 by mistake after having been distracted by a query from his co pilot . /com en/com040 592 jpg.. environmental capture may occur when a pilot carries out a certain task very frequently in a certain location thus a pilot used to reaching for a certain switch to select function a on an airbus a320 may inadvertently select the same switch on an airbus 321 when in fact it has a different function exemple 269 action slip and environmental capture (habituation).action slip and environmental capture (habituation).

What is the current approach to human error ?

Question 101-24 : Realisation that humans are fallible and that systems and procedures should be designed to minimise human error realisation that humans are infallible and that systems and procedures should be brought into line to prevent system/procedural errors realisation that humans are infallible and that systems/procedures should be designed to minimise human error realisation that humans are fallible and that systems and procedures should be brought into line to prevent system latent and procedural errors

.human factors as a term has to be clearly defined because when these words are used in the vernacular they are often applied to any factor related to humans the human element is the most flexible adaptable and valuable part of the aviation system but it is also the most vulnerable to influences which can adversely affect its performance .throughout the years some three out of four accidents have resulted from less than optimum human performance this has commonly been classified as human error.the term 'human error' is of no help in accident prevention because although it may indicate where in the system a breakdown occurs it provides no guidance as to why it occurs an error attributed to humans in the system may have been design induced or stimulated by inadequate training badly designed procedures or the poor concept or layout of checklists or manuals further the term 'human error' allows concealment of the underlying factors which must be brought to the fore if accidents are to be prevented in fact contemporary safety thinking argues that human error should be the starting point rather than the stop rule in accident investigation and prevention.to contain and control human error one must first understand its nature there are basic concepts associated with the nature of human error the origins of errors can be fundamentally different and the consequences of similar errors can also be significantly different while some errors are due to carelessness negligence or poor judgement others may be induced by poorly designed equipment or may result from a normal reaction of a person to a particular situation the latter kind of error is likely to be repeated and its occurrence can be anticipated exemple 293 realisation that humans are fallible and that systems and procedures should be designed to minimise human error.realisation that humans are fallible and that systems and procedures should be designed to minimise human error.

Breathing 100% oxygen at 40000 ft is equivalent to breathing ambient air at ?

Question 101-40 : 10 000 ft 8 000 ft 14 000 ft 18 000 ft

.we are about 75% water therefore the air in our lungs is always fully saturated with water vapour this means the air in our lungs is different to the air outside because it contains a much higher proportion of water vapour this water vapour exerts a partial pressure too and this competes with the other gases in our lungs the partial pressure exerted by water vapour in our lungs is 47 mmhg it is always 47 mmhg at any altitude whatever you are breathing in because it is always fully saturated with water vapour.. .the partial pressure of oxygen in our lungs at sea level is 103 mmhg 150 mmhg from the atmosphere but take away the constant 47 mmhg from the water vapour and this leaves 103 mmhg so in our lungs.. . sea level partial pressure of oxygen is about 103 mmhg. at 10000 ft this pressure drops to 55 mmhg but this is enough for normal fit people to get by on. above 10000 ft the oxygen concentration breathed in has to be increased to maintain the oxygen partial pressure at 103 mmhg ie more oxygen is added to the air mix in the mask. at 33700 ft breathing 100% oxygen still provides a partial pressure of 103 mmhg just like being at sea level as far as our bodies are concerned. between 33700 ft and 40000 ft the partial pressure of oxygen in your lungs decreases to 55 mmhg so although you are now breathing 100% oxygen through a mask the pressure this oxygen exerts in your lungs is only 55 mmhg a normal fit person is still ok as he is at the equivalent altitude of about 10000 ft but people with heart or lungs problems may start to feel the strain and many do. above 40000 ft even the 100% oxygen in your mask cannot provide enough pressure to push the molecules into the blood stream you need positive pressure added to your 100% oxygen to force it across the lung wall.. .we are ok up to 10000 ft because haemoglobin has cleverly adapted its behaviour with respect to the absorption and release of oxygen it is still able to gobble up oxygen from the lungs and almost fully saturate the blood even at the lower partial pressures experienced at 10000 ft this allows humans to live at these altitudes above 10000 ft though the haemoglobin struggles to absorb sufficient oxygen humans living above these altitudes peru etc have other adaptations but note there are almost no humans who live above about 12000 ft exemple 357 10 000 ft.10 000 ft.
