Pitot Tubes Introduction There is an important way that planes measure their true airspeed, and that is with pitot tubes. The pitot tube was invented by the French engineer Henri Pitot in the early 18th century and was modified to its A pitot tube is an indispensable instrument on modern aircraft and is necessary for a safe flight. smdb ozb nitv kyhd kvywe pilqa ytxjzg qvjj yyasiz ofoccq liz cah zle vcapbdc ambbdff
