1.	Why is a hole required at the rear end of the temperature probe?(a) Dual measurements(b) Redundancy(c) Reduce time lag(d) Convective coolingThe question was asked in exam.I'd like to ask this question from Temperature, Angle of Attack and Angle of Side Slip Measurements in division Air Data Systems, Altitude and Heading Reference of Avionics
Answer» Right option is (c) Reduce time lag To EXPLAIN I would say: To avoid time lags in the TEMPERATURE measurements, a leakage hole at the rear end of the probe ALLOWS for RAPID exchange. For REDUNDANCY, multiple temperature probes are placed in different parts of the aircraft.
