A SYSTEM AND METHOD FOR DETERMINING THE REAL-TIME EFFECT OF ICE ACCUMULATION ON AIRCRAFT SURFACES ON ANGLE OF ATTACK DURING FLIGHT A system includes a plurality of sensors along a surface of an airfoil operable to measure a first set of ice thickness values at a first time and a second set of 10 ice thickness values at a second time. The system further includes a processor configured to determine a first plurality of lift calculation variables and a second plurality of lift calculation variables. The processor also generates a threshold angle of attack 15 value and updates the threshold angle of attack value at the second time, based on one or more differences between the first and second sets of ice thickness values and the first and second plurality of lift calculation variables. The processor is further configured to send, to a 20 display, based on the updated threshold angle of attack, one or more changes to flight data to adjust the actual angle of attack of the airfoil. 200 2/3 Apply signal averaging for each ice 218 START thickness value within the second set oficethicknessvalues Generate, by a plurality of sensors along 2 220 a surface of an airfoil, a first set of ice Determine, based on a measured flight thickness values corresponding to data, a second plurality of lift a first time calculation variables Filter each ice thickness value within 222 the first set of ice thickness values Difference with digital signal processing between first set of NO ice thickness values and first 206 plurality of lift calculation Apply signal averaging for each ice variables and second thickness value within the first set of set? ice thickness values Determine, based on a measured flight Compare the second set of ice thickness data, a first plurality of lift values with the second plurality of lift calculation variables calculation variables against a data table Compare the first set of ice thickness Update at the second time, based on one 226 values with the first plurality of lift or more differences between the first calculation variables against a data table and second sets of ice thickness values and the first and second plurality of lift 212 calculation variables, the threshold Generate, based on at least the first set k angle of attack of ice thickness variables and the first plurality of lift calculation variables, a 228 threshold angle of attack value Send , to a display screen, based on the updated angle of attack, one or more 214 changes to the flight data to adjust Generate, by a plurality of sensors along the actual angle of attack a surface of an airfoil, a second set of ice thickness values corresponding to a first time 230 216 angle of attack NO Filter each ice thickness value within the above the threshold? second set of ice thickness values with digital signal processing Generate a warning signal FIG.2 REPEAT
