There really are times when you can have areas of yellow and red, in conditions that look like they favor convective activity, and in fact right next to convective activity, which are nonetheless stratiform and quite comfortable to penetrate. The key is knowing that convection is not there. Now how one is to know that without a good 'spherics device is beyond me. While I do see your point (and always have sided with you on your recurring theme of getting proper utility out of an aircraft), this particular flight was a return leg of an Angel Flight mission; it was not a mission critical freight dog flight. I certainly don't see any harm in erring on the side of caution in wanting to stay clear of level three and higher returns, especially when there is an advancing cold front in the area. Whether these particular returns contained destructive turbulence or not was not something I wanted to test. All of the weather conditions that day suggested they could be convective and that was enough for me. Additionally, my point in starting this thread was to question whether it is really the FSS specialist's job to imply that I am being too conservative when asking about the colorful radar returns? IMO, absolutely not. By the way, I recall one flight a couple of Septembers ago where the red returns were due to a local radar being set too sensitive for the falling *wet snow*. In this particular briefing, the FSS specialist was very good. He didn't imply that I was too concerned about seeing red. Instead, he investigated my concerns by pulling up the metars from the area, spotted snow being reported, then concluding that it was a radar sensitivity issue, not convective activity, that was causing the reds. -- Peter |

was not something I wanted to test. Actually, it's not something you EVER want to test. I inadvertently penetrated a Level 3 once, and would not willingly do so again. My point is that if you have reliable static discharge data, it's not something you're testing. You can't have strong convection with water droplets without having static discharges. It's just not possible. If the water is there and the static discharges are not, then there's no convection and penetration is safe. It's just that simple. My trip wasn't exactly critical either, and I could have deviated an extra 30 miles and been outside the convective SIGMET. But what's the point? Deviating around stratiform cloud with rain? Now without 'sferics, I would certainly have deviated. Or maybe not, if I had live lightning data piped into my cockpit. Additionally, my point in starting this thread was to question whether it is really the FSS specialist's job to imply that I am being too conservative when asking about the colorful radar returns? I made no comment on that part of your post. I think you made your point, it's been discussed, and I have nothing to add to it. No, of course it's not appropriate - but then you get what you pay for. Pesonally I prefer a self-briefing with DUATS. Michael |
