Abstract
In a method for stand-alone alignment of an inertial unit for an onboard instrument capable of being mounted in an aircraft, the method includes monitoring the appearance of a movement of the inertial unit during the alignment, suspending the alignment of the inertial unit in the event of the appearance of movement, and resuming the alignment of the inertial unit on the disappearance of the movement.
Claims14
A method for stand-alone alignment of an inertial unit for an onboard instrument capable of being mounted in an aircraft, including the following steps:
- monitoring the appearance of a movement of the inertial unit during the alignment;
- suspending the alignment of the inertial unit in the event of the appearance of movement;
- and
- resuming the alignment of the inertial unit on the disappearance of the movement, wherein
- the step of suspending the alignment of the inertial unit includes a sub-step comprising storing current values used for the alignment, and
- the step of resuming the alignment includes a sub-step comprising recovering the recorded values for the continuation of the alignment.
(canceled)
An onboard instrument capable of being mounted in an aircraft, the onboard instrument including:
- an inertial unit comprising means for stand-alone alignment;
- means for monitoring the appearance of a movement of the inertial unit during the alignment;
- means for suspending the alignment in the event of the appearance of movement;
- and
- means for resuming the alignment of the inertial unit on the disappearance of the movement, wherein
- the means for suspending the alignment comprises a memory in which current values used for the alignment are placed, and
- the means for resuming the alignment allows the current stored values to be recovered for the continuation of the alignment.
