    摘要: A method of detecting errors in air data sensing systems having multi-function probes being used in combinations to define probe systems includes a step (A) of, for each probe system, making a first prediction of an aircraft parameter as a function of local angles of attack at two member probes of the particular system, and making a second prediction of the aircraft parameter as a function of local pressure ratios at the two member probes of the particular system. A step (B) is performed in which, for each of the probe systems, the first and second predictions of the aircraft parameter are compared to determine whether the first and second predictions are within a predetermined threshold of each other. Then, a step (C) is performed in which, for each of the probe systems, if the first and second predictions of the aircraft parameter are not within the predetermined threshold of each other, then the particular probe system is identified as having a malfunctioning member probe.

    摘要: An optical system including an LCD rubbed for a 6 o'clock director orientation, one or more positively uniaxial retarders (A-plates) adjacent to the LCD, and a pair of positive retardance oblique waveplates (O-plates) on TAC substrates adjacent to one another and the input polarizer, all encompassed by a polarizer on each side of the optical stack, aligned for a normally white display.
