A method for independent alignment of an inertial measurement unit for a stand-by instrument in an aircraft includes: determining a status of the aircraft, that is to say whether or not the aircraft is in flight, and in the case where the aircraft is detected as being in flight, carrying out a flight alignment, and in the case where the aircraft is not detected as being in flight, determining a stability of the aircraft, that is to say whether the aircraft is on the ground or at sea, and in the case where the aircraft is detected as being on the ground, carrying out a ground alignment, and in the case where the aircraft is detected as being at sea, carrying out a sea alignment.

Method for independent alignment of an inertial unit for an onboard instrument of an aircraft

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.
