I had an experience that speaks directly to Navy vs AF culture (circa mid 90s), and the instrument procedures and publications discussion here. I was an Asst Air Officer in N31 for NAVEUR when Secretary Brown's mishap occurred. I flew into London one week only to find we were a VFR air force. The Admiral's response was almost immediate, find a way around this. We couldn't be restricted to VFR in Europe. Because I was an airline guy Air Ops gave the job to me, figuring I knew more about Jepps than any of the other aviators on staff. My first call was to USAFE. Got my equivalent there and asked him what their plans were for getting back into the air asap. His response was shocking. "Well, nothing. What can we do? We have our orders. It will get worked out. Nothing for us to do. " When I mentioned that it looked like the process being pursued would take many months, he was not swayed. USAFE was willing to be reduced to a VFR air force and not advocate anything that would get them back in the clouds. The Navy simply was not similarly disposed. We were not going to sit on our butts while a process played out thousands of miles away, without being at the table and no assurances haste was a priority.
