That is what I was trying to say-- Having seen these little buggers up close -I could not see how they could handle CHANGING conditions as the plane moved up n down n thru cold and hot air etc..
I always thot the airspeed indicators in state of the art glass cockpit commercial carriers and "spare no expense" militaty craft, was a few steps up from the simple airspeed indicator in an old Mooney.
I wonder what they have in that new Airbust - the 500 passenger thing - I bet it is reading three satellites all the time it is out of a hanger --The news said the thing has private showers etc..
Maybe a handball court?
Pilots of aircraft of all sizes need to know "indicated" airspeed. Some aircraft also display true airspeed, but not without indicated airspeed. We cannot do away with indicated airspeed--it's too important. The fact that it doesn't match true airspeed is unimportant, since we can determine TAS easily when needed, which isn't all that frequently compared to the number of times we check indicated airspeed.
