Peter, all

One thing that I have never managed to unpick with reference to limited info in PNs, and from other limited available references. is the role and function of the additional ‘scope’ sat almost as an afterthought on top of the AI Mk17 CRT 100 Indicator. Pic highlghts this. At first I imagined it might be a copy of the Pilot’s Collimator display, but wonder if it is FIS-related?

And finally, the iris-dimmable Warning Lamp towards the bottom of the CRT 100 – is this perhaps a component of the FIS or purely AI-related?
