Abstract
A device and a method for automatically generating a control order of an aircraft control surface The device (1) comprises means (9) for automatically calculating and transmitting, in the case of a suspected deficiency of a control surface control order, a limited auxiliary order, during a confirmation time of the deficiency.
Claims10
A device for automatically generating a control order of at least one control surface (2) of an aircraft, said device (1) comprising:
- first means (8A) for generating at least one control order;
- second means (3) for issuing such a control order to user means (50);
- third means (5) for monitoring the control order generated by said first means (8A), so as to check whether it has a correct value or a wrong value, a wrong value representing a suspected deficiency, and should such a suspected deficiency be detected, in order to check whether said control order has a wrong value during a predetermined confirmation time, so as to confirm the deficiency;
- and
- fourth means (6) for inhibiting the control order issue when a deficiency is confirmed,
- characterized in that it further comprises:
- fifth means for determining, as soon as a suspected deficiency is detected, an auxiliary control order, summing the latest generated control order before such a detection and a predetermined order value illustrating a tolerated error margin;
- and
- sixth means (9) for automatically transmitting to said second means (3), with a view to its issue as a control order:
- said control order generated by said first means (8A), in the absence of a deficiency and a suspected deficiency;
- and
- said auxiliary control order determined by said fifth means (9), as soon as a suspected deficiency is detected, and this, until the end of said confirmation time, from which:
- if the deficiency is confirmed, the issue of the control order is inhibited;
- otherwise, said control order generated by said first means is issued again.

A method for automatically generating a control order of at least one aircraft control surface, wherein:
- A/ at least one control order is generated;
- and
- B/ such a control order is issued to users means (50), wherein, in addition, the following operations are performed:
- said control order generated in step A/ is monitored, in order to check whether it has a correct value or a wrong value, a wrong value representing a suspected deficiency, and if such a suspected deficiency is detected, in order to check whether said control order has a wrong value during a predetermined confirmation time, in order to confirm the deficiency;
- and
- when a deficiency is confirmed, issuing said control order of step B/is inhibited,
- characterized in that furthermore, the following operations are performed:
- as soon as a suspected deficiency is detected, an auxiliary control order is determined, summing the last generated control order before such a detection and a predetermined order value illustrating a tolerated error margin;
- and
- in step B/, there is issued to the users means (50), as a control order:
- said control order generated in step A/, in the absence of a deficiency and a suspected deficiency;
- and
- said auxiliary control order as soon as a suspected deficiency is detected, and this, until the end of said confirmation time, from which:
- if the deficiency is confirmed, the issue of the control order is inhibited;
- otherwise, said control order generated in step A/ is issued again.
