Interpretation of what is raw data approach.
Crew room 737 discussion recently on what constitutes a raw data instrument approach. For example, take an NDB instrument approach. One view is it means conducting the approach with flight director off and using RMI needles for tracking. No FMC programming allowed. In other words basic instrument flying skill.
Another argued that raw data is flight directors on, FMC programmed and follow the magenta line using heading bug and VS mode. In other words not using Lnav or Vnav. Personally I think the latter is nonsense and not raw data.
