Weather Minimums
UK police Ops:
For getting the job done (VFR): 350' c/b and 1km viz, day.
600' c/b and 5km viz night (night VFR).
Wind speeds for us: engaging/disengaging rotors: 50kts. Worst wind I've flown in on the job: 75kts.

Seems like the original reason for this thread was for the poster to get some idea from other private pilots on their personal limits to help him decide on his.
Forget legal minimums(but NEVER take off if wx is below them) and forget forecasts (Mat Office personnel ARE on drugs and work in windowless offices!)
Know when to land and give up the flight, look stupid, be embarrassed, take some stick, but be alive to blush another day.

Raven,
Lots of useful info here I think. For me, the two best bits relate to the uncertainty of forecasts:
1. As MG says, get some dual experience of "bad weather" flying - it is amazing to me (now with a bit more experience) how low-time PPLs do not see the pretty obvious signs of in-flight weather deterioration and take the necessary steps;
2. Do what you can to improve on the forecast: definitely talk to yoour arrival site if you can, and any obvious alternate
BUT also do not forget, you are flying a helicopter: if you do not like what you see in front of you, and YOU are wishing you were not up here - LAND.

hey bovinedude and woolf,
I know all that stuff about departure single engine alternates and RVR being the deciding factor about whether there is an approach ban or not.
I was just taking issue with woolfs statement that
".... 60kts Wind, no cloud base and 500m RVR ." was your limit"
the implication for people who are not aware of IFR limits is that you could/would fly a normal line trip with no issue about cloudbase/ceiling at all. wheras if you had OVC 001 at aberdeen this would be a factor and is likely to pack you off to dundee (or somewhere) !

hey camp freddie:
You are quite right, there are certain limits concerning cloud ceiling/base for IFR flying even if all your approaches are precision approaches. Destination or Takeoff-Alternate limits do not require any cloud ceiling. However Destination-Alternates do, normally a cloud ceiling of Decision Height + 200ft and RVR + 400m. So for departing or returning to Aberdeen OVC001 is not really an issue if you can find a suitable Alternates.

Woolf
