IIRC the FG1 at Leuchars did not have an INAS so that was not a factor. The FGR2 did have INAS but had options of a full align or a partial align, that latter of course being less accurate.
The F2 didn't hold Q. While at Coningsby the OCU worked up the F2 while the F4 would hold Q on rotation. Once Leeming achieved initial capability the F3 QRA was mounted from there rather than Coninsgby.
