They record the information from the moment you turn the instrument on - which is probably when you turned the panel on. Therefore there is no concept of 'on' when switching to the A/H display. The gyros are used as part of the air model and are constantly calibrated by the external information including (in the Vaulter at least) the GPS.

In addition the one I'm familiar with has a built in magnetometer that calibrates to your installation and gives a rather nice always available compass.

Are the LX devices really running all the time? When you bring up a page showing the A-H it is not actually instant on - it takes a couple of seconds before it indicates that it is live. Presumably the sensors are alive, but there is something else which has to be on before you see the A-H display.

So many solid state A-H's have become available over a short period of time.. According to reports they all seem to work very well. Does anyone know whether the technology (both hardware and software) is common to the different manufacturers, or has each manufacturer developed their own approach? Within the LX Nav range, does anyone know whether the S80/S8 have the same sensors and software as the V9?
