A safety critical system is one which can have catastrophic consequences if it fails. So far we have been talking about productivity; the amount of a value a system adds. In the world of safety critical systems ‘reliability' is crucial. Reliability is a measure of how often and how dramatically a system fails.

In an ideal world we would want no accidents to occur at all, but in the real world accidents will happen, so safety critical system engineers put in an awful lot of effort to ensure the safety of their systems. Essentially they attempt to trade off the severity of a possible accident against the likelihood of that accident occurring. A severe accident is acceptable if it is extremely (very extremely) unlikely to happen. On the other hand a likely accident is acceptable if it is not very severe. Safety engineers work to mitigate accidents by a combination of making them less likely and less severe.

However there have been a number of very high profile and fatal accidents lately, where the failure is put down to ‘operator error'. We will present arguments that ‘operator error' is a misnomer; it is ‘system error' and a lot of the time errors involving users are predictable and preventable.

First consider the following two cases:

The Kegworth air disaster

On 8th JanuaryBritish Midland flight G-OMBE was an i/o error occured #125.1 from the UK's Heathrow Airport to Belfast. The aeroplane was a twin-engined Boeing model with a new computerised set of cockpit controls. One of the blades in the left engine detached and the crew began to start emergency action. The plane could be safely flown with just one engine, so the procedure was to shut down the damaged engine and fly on the working engine. The crew informed ground staff and an emergency landing was scheduled at East Midlands Airport near Kegworth.

The crew were aware of the fact that one of the engines was damaged not only because of instrument readings in the cockpit but because of a loud juddering. The Captain throttled down and shut off one of the engines and the juddering stopped. He had however shut down the good engine and the juddering had stopped just by an unfortunate fluke of aerodynamics, critical system errors. The aeroplane flew on powered only by its damaged engine. The instrument panel displayed this fact, but not in a way that any of the crew noticed. On final approach to the runway the damaged engine completely failed and the plane began to fall out of the sky. The crew realised the error and then tried to restart the good engine, but could not in time. The plane crash landed onto the M1 motorway just yards short of the runway at Kegworth. 47 passengers were killed and 74 seriously injured. The captain survived.

In the aftermath initial reports stated critical system errors both engines had failed and the tabloid press proclaimed the captain as a hero for managing to get the plane so close to the airport and landing it in such a way that many passengers actually survived. After the truth came out in the crash enquiry the same tabloid press denounced the captain and placed the blamed firmly with him.

The Paddington rail crash

On 5th October a slow moving commuter train left Paddington station in London heading for Bedwyn in Wiltshire. Just outside Paddington there is a large bank of signals on a gantry over the line. The signal for the particular line that the commuter train was on was at red. It was also notoriously difficult to see as it was partially obscured by overhead electrical cables. The driver of the commuter train passed through the red signal and his train was critical system errors over several lives when it was struck head on by a high speed intercity train travelling to London from Cheltenham. 31 people, including both drivers were killed in the collision and many were severely injured by the fireball which swept through the front carriages of the intercity train. The accident site closed down Paddington station, one of the busiest in London, for over a week, inconveniencing over a million travellers.

Subsequently it became clear that ‘SPAD' (signal passed at danger) events were quite common, and that systems recommended years earlier that would have prevented such accidents had not been implemented. The signalling systems were claimed to be so unreliable that drivers often knowingly passed through red lights. If they did not then the rail system would have most likely ground to a halt. createfile error 2 What is interesting is the reporting of these two terrible accidents; in the case of the Kegworth crash blame was firmly placed with the pilot and crew and they were vilified. However twelve years later attention was much more drawn to the system that the train driver had to use, and the consensus opinion was that blame should lay with the system, and the system needed modifying.

At the time of writing the Paddington rail crash enquiry is just getting under way. It will be interesting to see if it comes to the ‘operator error' conclusion this time.

Safety engineers collect and analyse a huge amount of data about the technology they use to build safety critical systems. The hardware which they critical system errors will be highly tested with known and documented failure tolerances. The use the most secure software development techniques in order to ensure that requirements for the system are collected and that those requirements actually reflect what is wanted for the system (requirements gathering is a notoriously tricky business). Then software is rigorously developed to meet those requirements. At all stages in the process thorough testing and validation is employed. The engineers expend prodigious effort in ensuring that they ‘build the right system, and the system right'. Many experts with experience of systems similar to the one being developed are consulted and a considerable amount of time and money is expended in order to get a system that is certifiably and explicitly correct.

All too often, at this point this bullet-proof technology is handed to a hapless operator who does the wrong thing with it and can cause a serious accident. In subsequent enquiries the failure is put down to ‘operator error' which is held to be in some way unavoidable. The failure cannot lie with the technology, particularly after all that effort was put into it to ensure its critical system errors. Operator error is a very convenient let out clause for the system developers. It allows then to shift blame away from their product onto operators.

When questioned it is clear that many developers do not consider users to part of the systems they develop; they consider users to be external to their systems. Therefore when users cause errors, the blame for the error lies comfortably outside their system.

A widening of what a system is

What is needed is a wider conception of what a system is. Consider a common safety critical system; the car. Cars are very dangerous, so much so the law insists that their user's (drivers) take training sessions and pass examinations before being allowed to use them, critical system errors. A car without a driver is not a complete system; unless it is rolled down a hill it will not do anything very dangerous without a driver. Therefore a safety analysis of a car which does not take into account its driver would be a fairly sterile exercise.

But many safety critical systems are put in place which do not take their users into account at all. Not only should users be brought into safety analyses, but also much more detail about the environment that is part of the system needs to be considered.

There are a variety of reasons why users are not generally included in safety analyses. Safety analysts like dealing with numbers, critical system errors. Given a piece of hardware they like to know how many times it is likely to breakdown in the next ten years, and the chances are there will be data available to tell them. They like to the know the cost of that critical system errors of hardware breaking down, and there may also be data telling them this too. They can then multiply the cost of breakdown by the number of times breakdown will occur and produce a quantitative estimate of how much running critical system errors piece of hardware for the next ten years will cost.

Such data does not exist for humans, or it is very suspect if it does. Because data for reasoning about human behaviour do not fit easily into the processes developed for reasoning about hardware and software, it tends to be ignored, critical system errors. Also information about human behaviour is not ‘black and white', critical system errors. Arguments can be made about the behaviour of automated computers that can give yes or no answers, but arguments about human behaviour will be much less deterministic. Because of this, taking account of users in safety analyses is rare.

Because questions about human behaviour cannot generally be given in a yes or no way, critical system errors, this does not mean however that no answers can be given. Psychology has developed many models of human behaviour that accurately describe and predict human performance. In particular there are many valid models of human perception that could have pointed to problems with the display configuration in the cockpit of the airliner that crashed near Kegworth.

The problem is to define design processes that can make use of the models of human behaviour developed by psychologists and sociologists, critical system errors.

How do safety engineers work to reduce the impact of accidents? Why is it crucial to reduce the likelihood of accidents happening?

Answer to this question can be found at the end of the chapter.

What differentiates the failure of a normal interactive system from the failure of a safety critical system?

Answer to this question can be critical system errors at the end of the chapter.

Responsibility for safety critical systems

In the previous section we discussed responsibility for interactive systems. We suggested that developers should move towards being responsible to users as well as customers. Responsibility for safety critical systems should spread even wider. The failure of a normal interactive system impinges on the user and possibly the user's employer; people who have to a certain extent agreed to use the system. Failure of safety critical systems impinges on a much wider stage and can affect people who have in no way made a decision to be part of the system.

Consider the following hypothetical example:

I step out on a road crossing with a car about yards away heading towards me. The car's ABS brake system fails, the driver tries to avoid me but strikes me. The car is a hire car. The ABS system on the car was developed by a subcontractor to the car manufacturer.

Who is responsible for the accident?

You are invited to discuss these issues in discussion 2.

Requirements Analysis for Safety Critical Systems


Requirements not only have to deal with events that are unexpected, they also need to anticipate the consequences of things going wrong, critical system errors. The unexpected can arise from many sources. Environmental events, often attributed incorrectly to “acts of God”, create problems through adverse weather and physical conditions, causing machinery to break down so that normal system functions cannot be assumed. Furthermore, critical system errors, people make mistakes. Even though many accidents are blamed on people making mistakes, human error is usually only one of many contributing factors. Safety critical systems should prevent, or at least reduce the chance of, human error, critical system errors. Requirements analysis has to try to anticipate these problems, but this is a difficult task. The problem is one of 20/20 foresight, or trying to anticipate all the possible combinations of future events that might occur in a designed system, and then trying to ensure that the design prevents or at least counteracts possible failures. Given the large number of possible errors people can make, in combination with extremes in weather and the many components in complex systems that could fail, critical system errors, we have a combinatorial explosion. So anticipating the future is a very difficult task; however, that does not mean we should not attempt it. Even standard methods such as object-oriented analysis and use cases draw attention to alternative as well as normal courses of action.

Critical Error

Techopedia Explains Critical Error

A critical error is an error that causes a program to abort. A critical error might occur in an operating system, a running application, program or software. In this process, the operation that was being performed is aborted, and data may be lost. This may even result in freezing or spontaneous rebooting of the computer.

A critical error can be due to causes such as:

  • An illegal instruction being attempted
  • A program attempting to perform something which is impossible
  • Invalid code being accessed

One of the most well-known critical errors in computing is the infamous Blue Screen of Death (BSoD) in Microsoft Windows operating systems.

Hi, Mitchell,

This indicates that a critical system process died. A critical process is one that forces the system to bug check if it terminates. This can happen when the state of the process is corrupted or otherwise is damaged. When this happens, as these processes are critical to the operation of Windows, a system bug check occurs as the operating system integrity is in question.
Built in Windows critical system services include,,,,,, and


If you recently added hardware to the system, try removing or replacing it. Or check with the manufacturer to see if any patches are available.

If new device drivers or system services have been added recently, try removing or updating them. Try to determine what changed in the system that caused the new bug check code to appear.

Check the System Log in Event Viewer for additional error messages that might help pinpoint the device or driver that is critical system errors the error. For more information, see Open Event Viewer. Look for critical errors in the system log that occurred in the same time window as the blue screen.

Check with the manufacturer to see if an updated system BIOS or firmware is available.

You can try running the hardware diagnostics supplied by the system manufacturer.
Confirm that any new hardware that is installed is compatible with the installed version of Windows. For example, you can get information about required hardware at Windows 10 Specifications.

Run a virus detection program. Viruses can infect all types of hard disks formatted for Windows, critical system errors, and resulting disk corruption can generate system bug check codes. Make sure the virus detection program checks the Master Boot Record for infections.

Use the System File Checker tool to repair missing or corrupted system files, critical system errors. The System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. Use the following command to run the System File Checker tool (

Look in Device Manager to see if any devices are marked with the exclamation point (!). Review the events log displayed in driver properties for any faulting driver. Try updating dial up error 720 related driver.

and press [Enter].

Wait until the process is done. This will take some time to complete.

copy and paste the command of get appxpackage

Step #3

Now, you need to restart your computer again.

Return to the [ctrl], [alt], and [delete] menu by pressing the keys simultaneously on your keyboard, click the Power icon, and choose “Restart.”

If you still see the Windows 10 Critical Error pop-up, continue reading to find another method that will work to resolve your computer’s error.

Fix #4: Create a New User Account With Administrative Privileges

If your settings or any changes critical system errors were automatically made to your computer settings cause the Start menu or Cortana to stop working, creating a new user account is the best option for resolving the issue.

Step #1

Right-click on the taskbar, and when the menu opens, choose “Task Manager.”

Alternately, you could press the [Ctrl], [Shift], and [Esc] keys at the same time to open it.

task manager on list

Step #2

When the Task Manager opens, click “File” in the upper left-hand corner.

Choose “Run new task” from the drop-down menu.

Type “PowerShell” into the window that opens and make sure the “Create this task with administrative privileges” box is checked before clicking “OK.”

check create this task with administrative privileges

Step #3

When the PowerShell opens, type

net user DifferentUsername DifferentPassword /add

without the quotation marks.

In this case, you should replace DifferentUsername with the actual username you want for the new account.

DifferentPassword is replaced with the password you want to use for the new account.

Neither the password nor the username can contain any spaces, and both will be case-sensitive.

When you have finished typing the command in, press [Enter] to execute it.

type net user differentusername differentpassword

Step #4

As with the other methods, you have to restart your computer.

Close the PowerShell window, critical system errors, press the critical system errors, [alt], and [delete] keys simultaneously on your keyboard, critical system errors the Power icon, and choose “Restart.”

When the computer restarts, log on to the new user account you created using the new username and password you typed into the PowerShell command.

choose restart button

The Windows 10 Critical Error should be gone when you log in to your new user account. If it is, critical system errors, transfer all your files to your new account and delete the old one, critical system errors.

Otherwise, continue reading for more methods of dealing with this issue.

Fix #5: Do a Clean Boot

Sometimes third-party apps will interfere with the Start menu function, critical system errors. A clean boot starts the computer with only necessary Microsoft apps critical system errors. If a third-party app is the cause, you can try updating it or uninstalling it to fix the issue permanently.

Step #1

Once you log in as an administrator and see the Critical Error message, press the [R] key and the [Windows] key together to open the Run box.

Type “msconfig” and click “OK.”

msconfig in run box

Step #2

The System Configuration window will appear.

Click the services tab.

Hide all Microsoft services” should have a checkmark next to it. (Click it if it doesn’t.)

Then click “Disable all.”

disable all microsoft services

Step #3

Now, click the “Startup” tab while you are still in the System Configuration window.

Click on “Open Task Manager” there.

open task manager on startup

Step #4

The Task Manager will open. Click the tab labeled “Startup.”

Select each item you find there and click the button to “Disable” it if it isn’t already disabled.

Now you can close the Task Manager.

select item and click disable button

Step #5

On the System Configuration window that is still open, click the “Apply” button and then “OK.”

click apply and ok button

Step #6

Restart critical system errors computer.

As the computer restarts, see if you get the Critical Error message. If the message is gone, repeat the steps above, but this time “enable” each app one at a time until you find the app causing the error.

Until you determine which app is interfering, you will need to use your computer in the Clean Boot state. If this method did not work, continue to the next method.

Fix #6: Update or Uninstall a Third-Party Antivirus

If you are using a third-party antivirus, the antivirus may be interfering with some components of Windows.

Since Windows 10 comes with Windows Defender, first, you should make sure Windows Defender has been deactivated if you are running a third-party antivirus. Running two antivirus programs at the same time can cause problems because the programs interfere with each other.

To find out how to deactivate Windows Defender, click here.

Virus and Threat Protection settings

Since each antivirus is different, the instructions below critical system errors general and not specific to any one antivirus program. Visit the manufacturer’s website for specific instructions on how to update or uninstall your antivirus.

Step #1

When you open the third-party antivirus program, you should be able to find an “Update” area.

Sometimes, this is located in a “General” folder. In other cases, you might find it under “Settings.”

Click the button to update the program.

update antivirus

Step #2

After you update and restart your computer, if you still see the Critical Error message, you need to uninstall your antivirus software.

Press the [X] and [Windows] keys at the same time. Choose “Settings” from the list.

settings on menu

Step #3

Click “Apps” in the Settings window.

In the “Apps & Features” sub-menu, scroll down until you find your antivirus program.

Click on it and then click the “Uninstall” button.

uninstall antivirus program

Step #4

As before restart your computer

If the problem is resolved, you can try reinstalling your third-party antivirus, critical system errors. If the problem appears after you reinstall the antivirus again, you will need to uninstall it and find another one or turn on Windows Defender and use that.

Shortly after Critical system errors 10 came out, it was notorious for having Start menu/ Cortana critical errors. As a result, Microsoft created a special troubleshooter that you can still find here.

This option works best if you think the errors might be related to issues with missed updates, critical system errors. All you need to do is download the Troubleshooter and run it, following the on-screen instructions.

Fix #8: Reinstall the Start Menu and Re-register Cortana

If the Start menu is pioneer p2500r error 11 or the registration process for Cortana is missing on your computer, this is the best option to fix it.

Also, if you run the Start menu Troubleshooter, and it tells you, critical system errors, “sprers.euxperienceHost” and “sprers.eua” applications need to be installed correctly; the following directions will resolve the issue.

Step #1

Press the [X] and the [Windows] keys together. Click on “Windows PowerShell (Admin).”

Choose “Yes” if the system wants permission for the app to make changes.

windows powershell admin on menu

Step #2

In the PowerShell window that opens, type:

Get-AppxPackage sprers.euxperienceHost
