Right traffic patterns at non-towered airports are where you find them. Not everyone, few in fact, carry the FAA’s Airport Facility Directory and perhaps they don’t consult all the available information, per the regulation, to find non-standard patterns. That’s why the FAA decided to put the notation RP 5 12 on sectional charts to denote that right turns were required. Pilots didn’t need to look in so many places to get flight critical information. The info was readily at hand.
Air Safety Foundation has proposed that NACO, the folks who provide the government alternative to Jeppesen IFR charts, adopt the same notation in the small airport diagram of Instrument approach procedure chart booklets when a non-standard pattern exists. Many IFR pilots do not carry sectional charts and unless they are especially diligent, may not check other sources. Since most IFR flights end in VFR conditions that means a VFR pattern. Life can get interesting when someone is flying a mirror image of the correct pattern.
Two questions: Do you find the notation on the VFR charts helpful? Would this notation be helpful on the IAP airport diagrams? By the way, Jepp already does this on their IAPs. Good idea or are we over thinking this?
