IRS Quick Align
In certain circles, there seems to be some confusion regarding "quick alignment" of IRS's. Am I correct in thinking there are no shortcuts when it comes to the initial alignment of IRS's ? I.e. around 10 minutes is always required to get the IRS's into full NAV mode (but subsequent movement of the mode selector from NAV to ALIGN to NAV will provide a quick alignment/update suitable for short hops). Seems to operate this way on the aircraft I work on. Are all IRS systems the same in this respect?
Thanks.
