@mts1, SDM is (or was anyawy) the final part of the FEAST test package, it's entierly computerised. It is called Strip Display Management because it is focused around a display of flight strips, but these are on a screen. No actual physical flight strips are used during the SDM.
@malakajin IIRC basic checking during stage 1 was removed several years ago, if you search a few hundred pages back in the thread you may find more details on it. When I did stage 1 there were no basic checking though.
