I ask a fool question:
Being an Ultralight pilot, do you prefer mechanical flight instruments
or digital meters?

One of my Chinese customers told me they prefer mechanical aircraft
instruments. Since they are more reliable than digital meters. They
are easy to read, liking a car derving meters.
But I have a little bit doubt. I knew digital meters are developing
direction. But I did not know where parts were popular used now in
digital meters,such as VAI, ALT, ASI, ADI or engine meters, in American
ultralight airplanes.

I find that where the displayed information is a somewhat constant
value, a DM works well, but for ever-changing info, an analog display
is better since we can predict the trend of the info. On most new
displays, IAS and altitude are diplayed both as numeric values as well
as tapes.
