Sorry.
Probably it is not available in PDF, I had it on paper many years ago. The graphs used the typical HSI and RMIs you could find in any non glass cockpit airliner. It must be an old document. A retired pilot handed it to me.
I can't find it and scan it because it is far away, in my homeland. If I ever find it and have time, I will scan it.
But you can purchase Trevor Thom's Instrument Flying and Radionavigation. It is still published, I think.
