Abstract
Flight parameter data is real time sampled in successive sample frames and temporarily stored in memory for one or more sample frame intervals, the stored sample values are examined to detect extremes in parameter values with time, periodic ones of the temporarily stored sample frames are permanently stored in memory at fixed frame intervals notwithstanding the presence or absence of extreme values in the sample set data, sampled frames intermediate to the fixed frames are stored only in the presence of extreme sample values amoung selected ones of the sensed flight parameters.
