- I've seen ultralights with a simple airspeed indicator mounted
- to a wing strut, in the free-stream, but where the pilot can see
- it. The construction is a clear plastic vertical column, about six
- or eight inches long with a 'pitot' inlet at the bottom, and 'static
- port' at the top.
-
- A 'pith-ball' (or whatever weight is required to float in the
- updraft) rides in the vertical section, which is slightly tapered.
-
- Since they're used for ultralights they're typically calibrated
- for fairly low speed (as man-carrying aircraft go), like 0 to 75 mph.
- I have no idea how accurate they are at the low end of the scale.
-
- Anyway, it would seem like one of these would be far cheaper and
- far more rugged than one of the ones with the whirling cups on the
- shaft. I expect you could just stuff it in your back pocket, between
- readings...
-
- I'll look in one of my 'pilot' catalogs when I get home and
- see if they carry 'em and at what price.
