Most local council airport managers/staff have little idea of operations of aircraft and submit NOTAM information because they were told to via the forms. If you have operated long term to country council strips in aircraft over 5700kg eventually you will get staff tell you to park somewhere that has no data on pavement strength or wingspan issues and you then have to tell them unless they can provide data you can't do that. I assume all conversion from local to UTC for NOTAM production is done by the NOTAM office, not by the council staff.
