Definitions
- the present invention relates to computer platforms for vehicle control and maintenance functions, and integrated therein. More particularly, the invention relates to a method and system for application execution on such platforms.
- This computer system or platform typically interacts with vehicle components through servers and with the driver or maintenance operator through screens and input devices. Certain sensitive functions of the vehicle are thus accessible from this platform, for example cruise control or ABS anti-lock braking for the automobile, the automatic piloting and various electronic instruments connected to the GPS for aeronautics.
- IFE platforms are mentioned in publications such as WO 2007/093327 or EP 1 367 683.
- the manufacturer guarantees the security of the manufacturer's domain by carrying out the validation and the integration of new equipment and / or computer applications in the platform dedicated to the crew.
- such a holder may be a rental company, a company owning a fleet of vehicles or even an individual.
- this holder can in particular be an airline which charters aircraft for the transport of passengers.
- These personal computers advantageously replace the heavy binder of the historically used pilot and allow the pilot to be itinerant, carrying his mission data and preparing his performance calculations before the flight from his hotel or the pre-boarding room.
- EFB Electronic Flight Bag
- TGL36 Temporal Guidance Leaflet of the Joint Aviation Authority JAA and included in Advisory Circular AC No. 120-76A of the FAA Federal Aviation Administration.
- a class I EFB is composed of a stand-alone portable PC that can be used autonomously, possibly powered by an electrical socket in the aircraft.
- the display and the control means for example keyboard and mouse, are autonomous.
- a class II EFB is similar to that of class I, for which a possibility of display and remote controls on cockpit means is proposed in order to be used during all phases of flight. For example, you can use a screen built into the cockpit, a keyboard and a TrackBall cockpit, the PC being connected to these remote interfaces via a docking station. The laptop is not attached to the aircraft which allows the pilot to dispose of it outside the aircraft.
- This class II EFB allows access to read-only avionics parameters. A great deal of independence between the EFB and the NSS platform is maintained allowing the airline to freely install the software it wants.
- EFBs are generally chosen by the airlines. They can be changed frequently or even be separate between two pilots operating consecutively on the aircraft. They then have the major disadvantage of requiring a complex integration and installation in the cockpit of the aircraft, for example because it is difficult to have a connector or a docking station generic enough to accommodate all the laptops available on the market.
- the aircraft manufacturer has no control over these computers in the airliner domain. In fact, these computers may not meet all the security standards applicable to manufacturers, creating security risks associated with running these computers.
- Class III EFB is equipment that is permanently attached to the aircraft, for example I 1 ILO ("Onboard Information Terminat" according to the English terminology, corresponding to a display and interaction device for the consultation of the aircraft. an electronic version of flight documents such as maintenance manuals) in the Airbus A340 (commercial name) or which forms a part number (identification number in the NSS system), of the manufacturer, for example the EFB in Airbus A380 (commercial name)
- This class III EFB class also allows access to read-only avionics parameters due to its integration into the system.
- the invention aims in particular at a method of executing a computer interfacing application with a crew of a vehicle, the method comprising: reading a removable medium, comprising said application to be executed, by means of a removable media player equipping an execution system embedded in the vehicle, the execution of said application by means of execution equipping said execution system and connected to said removable media player, said execution of the application requiring the permanent recording of data necessary for its execution only on said removable media.
- “permanent” is meant here the storage or the recording of data beyond the execution of the application, that is to say, data that lasts in the memories while the application is no longer in execution.
- This "permanent” storage is contrasted with “temporary” storage, which generally concerns the storage of data in a random access memory, such as RAM, to enable a microprocessor to efficiently carry out the execution of the application.
- the invention also relates to a method of executing a computer interfacing application with a crew of a vehicle, said application implementing associated data necessary for its execution, the method comprising: reading a removable medium , comprising said application to be executed, by means of a removable media player equipping an execution system embedded in the vehicle, the execution of said application by execution means equipping said execution system and connected to said reader removable media, said execution of the application being performed without the permanent storage in said execution system, said associated data.
- This permanent storage targets nonvolatile memories such as the registers of an operating system, any rewritable memory (EEPROM, Flash, ...) or hard disks.
- the ability to manipulate content data such as mission data that can be stored on the removable media and data attached to the aircraft (such as fault history and repair) that are stored in an on-board memory of the aircraft.
- content data such as mission data that can be stored on the removable media and data attached to the aircraft (such as fault history and repair) that are stored in an on-board memory of the aircraft.
- This is understood to mean the crew as opposed to the passengers, that is to say the personnel authorized to intervene and interact with the functional parameters of the vehicle.
- the crew includes, in particular, the pilot or pilots, the train crew and the maintenance operators.
- the company frees itself from the portable personal computer by the use of a removable medium that includes all the useful applications for the personnel considered. This avoids any problem related to the integration and installation of laptops with regard to plurality existing interfaces. Removable media follow, indeed, more generic connection standards.
- removable media is an economic gain compared to that of laptops equipping each stakeholder concerned. Indeed, removable media are traditionally seen as passive devices (without autonomous power supply) and lacking own means of execution. In practice, storage means are generally used.
- Such removable media is easily used by the pilot from his hotel, using a portable personal computer including an ad hoc media player.
- the interconnection of the removable media with the embedded execution system also allows its use in any phase of flight, for example via visualization and input interfaces provided in the cockpit.
- the execution system may take the form of a computer system integrated in the vehicle or for example a type EFB class III equipment attached to the aircraft.
- the unloading of the application from the removable media is also done without further problems for the embedded system, thanks to the implementation of mechanisms that prevent the application, when it is running, leaving fingerprints or traces on the embedded computing platform .
- it ensures a strong independence between the personal EFB and the platform, so that the airline can freely deploy, via removable media, the applications it wishes without affecting the security of the embedded system.
- the data associated with the application for its execution may for example be a driver, a library, a source code, an executable file, a configuration file, a computer registry file. These are saved in the removable media and are not deployed for storage to the runtime system.
- This independence ensures that the computing platform is not configured for a specific media environment. It can accommodate, via various custom removable media, different execution environments, for example a flight environment assigned to a pilot and a test environment and simulations assigned to a maintenance operator. In addition, the embedded system remains safe because it is not polluted by data specific to a non-resident application.
- the cockpit or a dedicated avionics bay may present a central processing unit (CPU) card connected to a screen dedicated to the information system, input means (keyboard and / or mouse) or designator dedicated to the information system and the media player accessible in the cockpit so that the pilot or operator can connect the media containing the desired application.
- CPU central processing unit
- the driver can connect its removable media in an ad-hoc drive provided on a PC terminal or on a portable personal computer, and thus access the desired applications and mission data from the outside the aircraft.
- said application is a portable application.
- a "portable application” is a software operating autonomously in the computer file storing the data of its own, without prior installation on the hard disk of the host computer. It is thus possible to freely use this application and associated personal data without leaving a trace on this host computer.
- traces or fingerprints are, for example, in the known systems of the state of the art, entries in the register, environment variable changes, installations or updates of shared libraries, temporary file creations, application binaries, and configuration files on the host platform hard disk.
- the execution system comprises an application launcher arranged to detect portable applications contained in a media connected to said reader, and said portable application is launched from the application launcher.
- the application launcher can, for example, detect U3 files, Framakey (standards for the development of portable applications) or any equivalent format, and display the corresponding applications for selection by the user.
- said removable media comprises an operating system, the method comprising, prior to said execution of the application, a boot step ("boof") of said execution system on said operating system, said application being executed in the environment of said removable media operating system.
- boof boot step
- the operating system used by the pilot or the operator is not related to the vehicle itself but to the removable media. This solution makes it possible to dispense with certain legal provisions relating to the use of operating system.
- said execution system comprises an input / output basic system (BIOS) configured to boot ("boot” according to a widespread Anglrios) said execution system from an operating system stored on the removable media connected to said reader.
- BIOS input / output basic system

- said execution system comprises a virtual machine executed at startup, said operating system being executed in said virtual machine.
- said execution system comprises an operating system arranged to be executed in said virtual machine.
- At least two virtual machines are instantiated from a single hardware (CPU) execution system. so as to provide two distinct environments, for example one related to the aircraft manufacturer and the other related to the airline. This eliminates the use of two CPUs whose cost, consumption and physical and thermal congestion would be greater.
- said execution means form part of a removable module of said execution system, in particular it can be a removable CPU card.
- said removable medium is one of the set comprising a USB key, a flash memory, a memory card (SD card, compact flash, etc.), a compact disc, a disc DVD.

- step 302 subsystem 120 starts with running operating system 123-1.
- the pilot can conventionally use the applications 123-2 already integrated by the aircraft manufacturer (step 304).
- step 306 the driver inserts, in the USB 128, the USB key 200 containing all its mission data, including checklists and flight planning. These data were prepared in advance by the pilot, for example at his hotel as explained below. This data is accessible through a portable application 210 developed by the airline for all its pilots.
- step 308 the subsystem 120 detects, by the plug and play mechanisms, the insertion of the key 200 into the reader 128 and starts the launch application 123-3.

- the operating system embedded on the computer 400 is in particular of the same family, that is to say having a binary compatibility, that the 123-1 integrated in the aircraft 1 by the aircraft manufacturer.
- the driver then connects his USB key 200 to the port 410 of the computer 400. Either using a launcher application provided on the computer
- the driver accesses its portable application 210 stored in the key 200.
- the portable application 210 is thus executed.
- the driver performs the desired treatments, for example modifies the data, reads them, adds them, and so on.
- the application 210 is closed. Since it is a portable application, no trace is also left on the computer 400.
- FIG. 1 A second embodiment of the invention will now be described with reference to FIG.
- the operating system for the execution of the application 210 is no longer embedded in the subsystem 110 or 120 but in the USB key 200 on which the subsystem 120 begins. (in the sense of the Anglicism "boot”).
- the other features described above in connection with FIGS. 1 to 4 may apply to this embodiment.
- FIG. 5 illustrates this second embodiment of the invention with the aid of a simplified representation of the subsystem 120 to which is connected the USB key 200 of a driver.
- the hard disk 123 does not store any particular data. Nevertheless, it can be expected that an operating system, applications and associated data are stored thereon to start system 100 startup in the absence of USB key 200.
- the processor 121 (and the motherboard of the subsystem 120 in the broad sense) comprises, in read-only memory, a BIOS (Basic Input Output System) 121-1 which specifies the list and the order of the devices to be consulted for the start-up. of the operating system. This is, for the skilled person, the boot order of the BIOS.
- the BIOS 121-1 specifies to "boot” initially on the USB drive 128 and failing that, to start on the hard disk 123. It is understood that the system may have several removable media players 128 and that the Corresponding BIOS can respectively indicate each of these drives in a predetermined order before consulting the hard disk 123.
- the USB key 200 has, in addition to applications 210 and 210 ', possibly but not necessarily portable, an operating system 212 and drivers 214.
- the operating system 212 is not installed, that is to say whose configuration is not yet associated with a specific hardware layer (or hardware).
- Drivers 214 are certified in advance by the aircraft manufacturer and provided to airlines with aircraft from this aircraft manufacturer. These drivers 214 are preferably generic in the sense that they allow the operating system 212 to recognize any type of equipment whatever the subsystem 120 and the aircraft 1 used in association with the key 200 of the pilot. Thus, it is possible to use the key 200 on other computers.
- the aircraft manufacturer provides the drivers for a number of major operating systems as well as for network-accessible services provided by the aircraft manufacturer (print server, avionics parameters access service, KCCU unit [for "Keyboard Cursor Control Unit”])
- the airline is free to integrate or not these functions on the USB key 200 to allow the pilot to access it.
- the driver supplies the system 100 and therefore its subsystems 110 and 120, in step 600.
- step 602 the processor 121 accesses and executes the BIOS 121-1.
- the system determines, in step 604, if there is an operating system accessible on the USB port 128, that is, if a USB key 200 hosting a system of operation is connected. If not (step 606), the subsystem 120 starts on a next device listed in the BIOS, for example on the operating system of the hard disk 123.
- step 608 the subsystem 120 loads the operating system 212 into RAM for execution by the processor 121.
- the initialization of the operating system 212 comprises, in step 610, the loading of the generic drivers 214 present in the key 200.
- the drivers 214 corresponding to the peripherals and installed hardware components are loaded by mechanisms of plug and play.
- the operating system 212 discovers the BIOS, the chipset, the CPU, the video card, the other peripherals of the subsystem 120 and loads the useful drivers again. for these different components present.
- a dedicated application automatically executing lists the applications 210, 210 'present on the USB key 200 and presents them to the pilot at step 612, that is to say the pilot, himself even, through the file system, accesses the application
- step 614 the pilot selects and starts the execution of the desired application, for example the application of checklists.
- the use of the application 210 allows the driver to access the data (read and / or write) in the key 200. Once the operation of the application 210 is completed, it is terminated, at step 616 at the execution of said application 210. No trace of this execution is stored permanently in the subsystem 120, in particular on the hard disk 213.
- the computer 400 is configured in its BIOS in the same way as the subsystem 120 previously mentioned in connection with FIGS. 5 and 6, namely to boot on the USB port 410.
- the driver is thus able to start its operating system 212 on any PC, portable or not.
- the pilot finds himself in the same working environment outside the plane and on the plane.
- the laptop 400 provided by the airline to access the portal and corporate service is used only from the USB key after a reboot when inserting the key 200.
- the hard disk 408 which contains the Desktop office environment is not used and no trace is left on when using the airplane working environment from USB key 200.
- This third embodiment is very similar to the second embodiment described above except that the subsystem 120 has a virtualization layer which releases the operating system 212 from hardware constraints, especially with respect to drivers 214.
- FIG. 7 illustrates this third embodiment of the invention with the aid of a simplified representation of the subsystem 120 to which is connected the USB key 200 of a driver.
- the hard disk 123 stores a first host operating system 123-4, for example a linux kernel or a linux distribution, a virtual machine 123-5 arranged to be executed in this first operating system 123. 4, a second operating system 123-1, for example the same as that mentioned above in connection with Figure 2, and 123-2 applications executable in the second operating system.
- a first host operating system 123-4 for example a linux kernel or a linux distribution
- a virtual machine 123-5 arranged to be executed in this first operating system 123. 4
- a second operating system 123-1 for example the same as that mentioned above in connection with Figure 2, and 123-2 applications executable in the second operating system.
- the virtual machine may be VMWare, QEmu or XEN for example.
- the first operating system 123-4 is executed directly on the specific hardware layer 800 of the aircraft (by the use of appropriate pilots). Then, the 123-5 virtual machine is automatically launched, followed by the "traditional" operating system 123-1 proposing to the pilot the various 123-2 applications.
- USB key 200 is similar to that described with reference to FIG. 5, except that, because of the 123-5 virtualization layer, the drivers 214 'are not generic to satisfy a maximum of material layers. 800 but are specific to the virtualization layer or 123-5 virtual machine.
- the boot order in the simulated BIOS at the level of the virtualization layer is specified, indicating the port on which a medium with an operating system, for example a CD-ROM, is presented, and possibly other default ports.
- a medium with an operating system for example a CD-ROM
- the USB port is the main boot port to boot on the operating system 212.
- this third embodiment does not limit the number of operating systems running in parallel on the virtual machine, from the same hardware layer. In particular, no system In addition, multiple drives 128 may be used to boot multiple operating systems.
- the presence of the 123-5 virtualization layer makes it possible to use the same processor for both the aircraft manufacturer and the airliner domain. The separation between these two domains is then achieved by the instantiation of each of the corresponding operating systems in the virtual machine. It is thus possible to have a single processor in the aircraft.
- USB key 200 A portable use of the USB key 200 (see Figure 4 also) is also conceivable, in which case the computer 400 will have the same linux kernel and virtual machine means that the subsystem 120 mentioned above in connection with the third embodiment.
- This variant relies on the use of a removable module of the processor 121, allowing the airline to manage itself the obsolescence of the CPU 121.
- the aircraft manufacturer provides an empty slot to put a card
- CPU 121 at the free choice of the airline. The latter can choose the CPU power it needs. It can also decide on its replacement for obsolescence.
- the airline also has a partial physical freedom on the onboard system 100, 110, 120.
- the CPU boards 121 used comply with avionic standards, for example covering the electrical and / or thermal envelope, in order to guarantee good availability of the function and good safety.
- An STC certification (“Supplemental Type Certification" in the English terminology) may be provided for this purpose. Thanks to the invention, the airline can freely develop the applications it wants and use them in its aircraft without requiring the intervention for certification and integration of aircraft manufacturers.
- a removable media comprising a GPS navigation application can be provided.
- the driver prepares, on his personal computer at home, his journey and the various crossing points.
