I also carry an astrolabe (secured by string) in my aircraft. After a very long flight it may be necessary to calculate last light, which may be different from the location I took off from.
In a remote place or if power has failed, I can always quickly recalculate based on my location. I haven't had it calibrated for a while. Does any one know of an accredited service centre in Australia, or must I return it to the manufacturer?
