j2 Universal Toolkit - Questions and Answers
j2 Software Network Requirements and Operating System
Q: Is it possible to network the j2 Software?
Absolutely yes. This is a core benefit of the J2 software. The core framework is a based on a Microsoft SQL database. If you are already running MS operating system then networking J2 is very straight forward.
Q: What hardware specification is required to run j2 Software?
The minimum hardware specification for a stand-alone installation is summarised below:
| Processor | Intel 2.40GHz Processor |
| Memory | 2GB |
| Hard Drive | 500GB for Workstation/Server 50GB for Workstations |
| Graphics | 512 MB 3-D Video Card Supporting DirectX and OpenGL |
| Mice | Standard 2 Button Mouse |
| Keyboard | Standard QWERTY Keyboard |
| Operating System | Windows XP Professional |
Q: What operating systems is the J2 software compatible with?
The j2 software can run on Windows XP and Windows 7 operating systems. It will not run on Windows Vista. There is a software assurance element to the annual renewal that will ensure that J2 Software also is compliant with new operating systems from Microsoft as they are introduced.
Q: Can J2 software run on Windows XP and Windows 7
Absolutely yes. J2 software is validate to run on both operating systems. We do not run on Windows Vista.
Q: Is j2 software able to run on 32 bit and 64 bit?
Absolutely yes. We are validated to run on both.
Qualification and Certification
Q: Can j2 Software be used to support Flight Test Programmes
The j2 Flight Test Suite is designed specifically to be used in supporting flight test programmes. The software can take flight test data in real time, run analyses in minutes and feedback instuction to the aircraft whilst still in the air. In addition the predictive aircraft model can be used directly to simulation providing a valuable Test Pilot briefing tool identifying and mitigating risk proir to the test flight.
It is possible to run the entire flight test envelope using the j2 Flight Test Suite software to identify and evaluate areas of sensitivity requiring more detailed evaluation.
For more information on how the j2 Software can be used to significantly shorten the duration of flight test programmes please look to the pdf file attached to the news item.
Software Functionality
Q: Do you have to write any scripts to run cases or analyses in J2.
No, no script writing or code writing at all. This is one of the key advantages of using the j2 Universal Tool Kit software and contributes greatly to how much faster you can go without adding manpower or work hours. The emphasis with j2 moves from the endless writing of code and/or scripts, a significant bottleneck, to using the valuable aerospace domain knowledge within the team to conduct significantly more and more valuable analysis quickly and easily.
Q: Just how many cases can I analyse and how fast can j2 software analyse these?
You can run anything up to 10,000 cases at present. The j2 software would expect to complete an initial analysis on these cases in one go without any need to write scripts in order to run each case. You might expect to run say 3000 cases in minutes not hours. We can be more precise on this if we have a better view of the project you are working on.
Q: Does the j2 software have any version and change control logic in it
Yes, there is a complete version control and change control capability built into the j2 software. The j2 Universal Framework has a Microsoft SQL database at its core allowing for the complete raft of change and update traceabilty, user permissions, teams allocation, viewing/editing privaledges etc that you would expect when using a mature and powerful database toolset.
Q: How quickly can j2 software qualify the impact of a change to an existing aircraft.
Provided you have an existing aircraft model that can be integrated into j2 software then the qualification can be completed very quickly.
The change is added as a delta to the base model, so any number of changes or sensitivities can be analysed in one go. Furthermore the change can be flown straight to Simulation in real time and a Pilot can assess the actual impact of the change on aircraft handling or a series of potted manoeuvres can be programmed into j2 and the auto pilot can fly them and provide a visual comparison of the flights from a number of design cases using the 3D viewing platform, J2 Virtual.
Q: Can I bring in my own trusted equations and/or other data sources into the j2 software environment?
Absolutely yes. It is a key tenet of J2 that you can still use your trusted tools and code whilst taking advantage of the powerful analytical and evaluation capabilities of J2. It also helps with any transition as you build confidence and trust in j2 software quicker.
Q: Can J2 software run on Windows XP and Windows 7
Absolutely yes. J2 software is validate to run on both operating systems. We do not run on Windows Vista.
Q: Can j2 software be used on a network?
Yes. The J2 software has a MSSQL database at its core. All the licenses are floating and can be easily networked.
Q: Can I use and fly models built in other code through J2 into Simulation?
Absolutely yes. This is a significant advantage of j2 software. These tend to be professional type tools. You will also need the J2 Pilot SDK to enable you to make the necessary integrations into your SIM environment.J2 can provide professional expertise in this area.
Q: What can I visualise using J2?
There is a powerful charting engine with the j2 software. This means you can set up and run template analysis at any time. You can also use the J2 virtual to run a 3D animation of the analysis providing a visual insight into what the graphical data is telling you. This can be used to ‘Visualise’ specific manoeuvres, dutch roll or to superimpose any number of variants and fly them off against each other.
Q: Am I able to ‘fly’ my models out to simulation?
Yes. The data driven solution offered by J2 allows you to link into any simulator platform with any combination of visuals and hardware in the loop and fly your design. J2 also integrates fully with Lockheed Martin Prepar3D and is able to provide a ‘professional’ version of this simulation software
