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.

Method for stand-alone alignment of an inertial unit for an onboard instrument capable of being mounted in an aircraft, and an onboard instrument being able to use such a method

The invention relates to a system including two integrated electronics instruments mounted onboard an aircraft and communication links between the two integrated electronics instruments, each integrated electronics instrument including independent determination of flight parameters of the aircraft and display of either flight parameters or navigation parameters of the aircraft. The system also includes a selection module making it possible to choose, from the sensors of the two integrated electronics instruments, those retained for determining the flight parameters. Embodiments of the invention also relate to a method using the system described above. The method includes selecting from the two integrated electronics instruments the sensors retained for determination of the flight parameters according to their availability, and displaying the determined flight parameters on the display of any one or both of the integrated electronics.

An embodiment of the invention relates to a method for managing the display of a rotary indicator on a digital screen, the method making it possible to permanently display in a window at least one value of the indicator in the form of characters, the values scrolling vertically in the window, a distance d defining a spacing between two characters of two successive values. The distance d varies between a value dwhen two successive values are visible in the window and a value dwhen a single value is visible in the window.
