Abstract

The display system comprises means (6, 7, 9) for automatically presenting a format in accordance with a prerecorded display configuration, upon a change of format on a screen (3) of said display system.

Claims

1. A method for display context synchronization for a display system of an aircraft, said display system exhibiting a distributed architecture and comprising a plurality of units, each of said units comprising:

a viewing screen able to display one of a plurality of different formats; and

a control panel comprising actuation means allowing an operator to control the display on the viewing screen of one of said formats so as to present it in accordance with a particular display context which represents a display configuration, said display context defining a set of particular options which have been selected for the associated format,

wherein;

for each unit, a display configuration is automatically recorded in a memory forming part of this unit, for each of the formats able to be displayed by this unit;

the following are recorded in the memory of a unit, as display configurations;

for the format which is currently displayed by this unit, the display configuration such as displayed; and

for each of the other possible formats, the corresponding display configuration which has been displayed last for this format on all of the other units and, by default, a default display configuration; and

when the display of a new format is requested by an operator via the control panel on a particular unit, the recorded display configuration which is associated with this new requested format is automatically extracted from the memory of this unit, and this new format is displayed in accordance with said associated display configuration thus extracted.

2. The method as claimed in claim 1,

wherein, when a new format is displayed in accordance with an associated display configuration on a unit, the control panel of this unit is synchronized with this new display configuration.

3. The method as claimed in claim 1,

wherein said display system is intended for a single pilot of the aircraft, and wherein, when on a unit of said display system, the display is requested of a new format which corresponds to a format already displayed on another unit of said display system, this new display is not carried out.

4. The method as claimed in claim 1,

wherein said display system is intended for a single pilot of the aircraft, and wherein, when on a unit of said display system, the display is requested of a new format which corresponds to a format already displayed on another unit of said display system, a swap of the formats is carried out between these two units.

5. The method as claimed in claim 1,

wherein, upon booting of a unit, the following are recorded in the memory of this unit, as display configurations:

if one of the other units of said display system is not in the booting phase and if, moreover, the communications are refreshed, all the display configurations such as recorded in the memory of this other unit; and

otherwise, default display configurations.

6. A display system of an aircraft with synchronized display context, said display system exhibiting a distributed architecture and comprising a plurality of units, each of said units comprising:

a viewing screen able to display one of a plurality of different formats; and

a control panel comprising actuation means allowing an operator to control the display on the viewing screen of one of said formats so as to present it in accordance with a particular display context which represents a display configuration, said display context defining a set of particular options which have been selected for the associated format,

wherein;

each of said units comprises moreover;

recording means for automatically recording a display configuration in a memory of said unit, for each of the formats able to be displayed by this unit, said recording means being formed so as to record in said memory, as display configurations;

for the format which is currently displayed by this unit, the display configuration such as displayed; and

for each of the other possible formats, the corresponding display configuration which has been displayed last for this format on all of the other units and, by default, a default display configuration;

first means for automatically extracting from said memory the display configuration which is associated with a new format, when the display of this new format is requested by an operator via the control panel of this unit;

second means for displaying this new format on the associated viewing screen in accordance with said display configuration thus extracted; and

a data transmission link which connects said control panel at least to said recording means; and

said display system comprises, moreover, a data transmission network which interconnects the recording means of the various units of said display system.

7. The display system as claimed in claim 6,

wherein each of said units comprises, moreover, synchronization means for automatically synchronizing the control panel of the corresponding unit, with a display configuration in accordance with which a new format is displayed.

8. An aircraft,

which comprises a display system such as that specified under claim 6.
