NTSB: Crossfield Not Warned Of Adverse Weather
Avweb's story, which has a link to NTSB's factual report, notes that Scott
Crossfield was not warned of adverse weather. However, he did have access to XM Satellite Radio with a subscription to its basic weather package. The autopsy likewise isn't suggestive of any obvious causative medical issue (unless I'm misreading it): http://www.avweb.com/avwebflash/news...958 21-1.html |

NTSB: Crossfield Not Warned Of Adverse Weather
Using XM radio to avoid Tstorms can be pretty hazardous unless you
allow a very wide margin of error. 1. Time delay up to 15-20 minutes 2. Max Precip isn't strongly correlated with max turbulence 3. Lightning shows cloud to ground only, not cloud to cloud. |

XM Wx should easily keep you clear of level 5-6 stuff, and is much better than depending on controllers to avoid big CBs. If Crossfield's XM Wx was working, he was either ignoring it or pushing way too hard. -- Dan T-182T at BFM |

3. Lightning shows cloud to ground only, not cloud to cloud. Interesting. I use WSI's downlinked weather service, but wondered if XM was better due to their lightning strike date. Is this limitation (cloud-to-cloud) documented on their site, or in other words, how did you learn of this? I am curious from a WSI comparison point of view. -- Peter |

Last I checked many controllers only have transponder indications with no weather on their display at all. Even if they can paint the weather, they have no obligation to help you with weather if they are under heavy workload. Danny Deger Lots of good flying stories on my web site, www.dannydeger.net |

I am hoping that ADS-B will help to prevent these kinds of tragedies. Having real-time traffic and weather data streaming into your avionics from ground stations should make all of us safer if we know where to look for each other in flight, and we all give severe weather the respect and wide berth it deserves...
