IOR and AOG

“IOR” and “AOG”

I have seen in various ACC internet forum people wondering about “IOR” and “AOG” which are two labels pasted in the file holder of late ACC.

If you walk into the office of late Sir Arthur Clarke you will notice that on his desk, there is a file holder labeled as “IOR” and “AOG”. When I walked into the office for the first time, I also wondered what it meant.

So, onetime when I asked him what it actually meant, he said;

“IOR” - Immediate Operation Requirement (means “IN”)
“AOG” - Aircraft On Ground (means “OUT”)

he said those are terms used by RAF.
