Yes, I have a very poor English.

Due to previous message, there was a person told me that there are some
car fan refit their cars using digital airpseed indicator (numeric
showing indication) in America. I told some Chinese car refit fans.
First they don't believe it. Second they want to know how to do it.
Here is the previous message:
"There is an interesting exception to all of the above. Many home-built
aircraft have a very basic set of flight instruments, often using
altimeters and compasses intended for automobiles or small boats, along
with an inexpensive Italian air speed indicator. The exception is the
inclusion of a gyro horizon, usually vacuum-driven but sometimes
electrical. This reflects the occasional need to descend through a
cloud layer, during which the wings must be kept level."

Thank you so much.
But digital meters just used DC.? Pitot tube is used mechanical meter.

Your English is poor, and you question did not communicate what you were
trying to ask, very well, at all.

What type of digital airspeed meter are you trying to use? How do you mean
that a fan would be used to help this to happen?

Much more thought is needed, in asking your question. Be specific, and tell
us more of what you were told.
