AE215: Aerospace Measurement Laboratory
Description: Wikipedia define measurement as the process or the result of determining the ratio of a physical quantity, such as a length, time, temperature etc., to a unit of measurement, such as the meter, second or degree Celsius. Which is essentially what we learn in this course. Measurements are very important and critical part of Aerospace Engineering. Specially today more or less every flight is extremely dependent on what is measured by the on board sensors. Flying at zero visibility and Auto Landing are the direct results of advancement in measurement techniques in the past decades.
