CB explodes into a wild, killer storm and the original large storm dries up.
It happens frequently. A classic example is the cause of the Lockheed L-1011 crash at DFW on Aug. 2, 1985. NWS radar detected a large storm north of DFW and a pinpoint echo between it and the runway. Only 16 minutes later the large storm was gone; the pin point echo had exploded into a supercell producing multiple downbursts and that major accident. All that is described in detail in the NTSB Accident Report on the DFW accident and has been detailed in a commercially available radar training course. So there is no excuse or reason why every candidate for a higher pilot rating isn’t first made aware of those convective storm facts. FAA, NTSB and pilot training organizations all bear guilt for not creating training requirements, Safety Bulletins and training regimens that ensure pilots receive proper convective storms training and knowledge before certification for an advanced pilot rating.
Another Thing to Consider
Returning to the subject accident involving the converted Beech, the NTSB report on it contains a statement that must be noted; “The controller did not provide any weather advisories to the pilot prior to the airplane’s encounter with the adverse weather.”
The message from that is, always keep in mind that the captain actually “controls” the flight and is responsible for its safety; the other guy is only a “traffic coordinator,” a “traffic adviser.” P•ilots with airborne radar must use it and their knowledge of convective weather as primary for avoiding dangerous areas of a thunderstorm, black areas near them as well as the colors. T&T
Considered a pioneer in onboard radar and convective weather training, Archie Trammell is a highly respected safety consultant whose lectures, video programs and instruction classes on the proper use of weather radar have been used to train thousands of pilots and more than 4,000 business flight departments.
