Just because it is new doesn’t mean it is always better. One of my profs banned calculators when they first came out (the lowly HP35) because he felt you should be able to use paper, pencil, and slide rule. After all batteries run out.....
Mine banned calculators in class “unless I bought one for every member of the class.” Marxist asshole, Finance class, Business School, UMass/Amherst, 1974. School hasn’t changed except that all admissions now are done through pure affirmative action. Class makeup is kept under 35% white male, despite student qualifications. Coming to your state if Obama wins reelection.
It seems that airline protocols now simply assume the computers are correct.
Sounds like my husband’s profs. Dear hubby did almost all of his Engineering Physics degree work with slide rules.
