Altimeters & Air-Speed Indicators usage
בתגובה להודעה מספר 1 שנכתבה על ידי Dynamite שמתחילה ב "האם מאז ומעולם היו מכשירי גובה ומהירות במטוסים?"
I don't know exactly when altimeters & air-speed indicators were first installed, but I do know that WW1 aircrafts were equipped with those instruments.
BTW, at the begining of the aviation age, a 2000ft vertical distance was required from one aircraft to another in civilian flights since their instruments weren't so accurate, that was called CVSM and it's still beening used in some parts of the world, but today, we mostly use RVSM which only requires 1000ft seperation.
