Hiya guys,

Purely from memory, and my experiences with 47SF running up to GW1, I understood that the SCINS (Special Configuration Inertial Navigation System) was a blend of a ring [email protected] gyro and an INS system. It certainly never replaced the navigator, who was needed to push the memory button as the wheels hit the ground to store the touchdown point. FOM (Figure Of Merit) featured heavily in the engineering banter about the system, and, always something of a mystery to GEs of the day. Unfortunately, I was never sent on a course for SCINS, though Tucker T claims to have done some sort of course on it. I do know that the Nav who operated it on my det to the Gulf (Arthur Chapman ?) found it very useful. I'm sure that if my memories are wrong someone will put me right. Meanwhile, best to all posters on this ever lengthening thread.
