SINGLE CDNA LIBRARY ANALYSIS OF GENE EXPRESSION

Not Available Aircraft icing is a known hazard to military and commercial flying. Onboard de-icing systems are effective but are applied to larger aircraft, not small and/or commuter aircraft and helicopters. What is needed is an onboard means for pilots to observe, in a timely manner, whether conditions ahead of the aircraft represent an icing hazard, so that evasive action can be initiated. A key component of icing prediction is the ability to remotely measure cloud region temperature to an accuracy sufficient to determine if the temperature is in the range of 0 degrees to -10 degrees Celsius, i.e. is in the liquid water super cooled region. Technology Service Corporation has developed a radar-based concept that promises to remotely determine a range resolved measure of the temperature in a cloud region. The method is an extension of the well known two-frequency radar method of remotely measuring cloud Suspended Liquid Water Content, that is another key component of icing prediction. The new temperature measuring method can use the same radar equipment as the two-frequency method. It should also be possible to integrate the new method with existing A/C weather radars. BENEFITS: If successful this technique, when integrated with a radar system that otherwise remotely measures cloud liquid water content, will provide a self contained sensor system that will accurately predict icing hazard conditions ahead of an aircraft. It would apply to commuter aircraft and helicopters.
