...face forwards and not backwards?
OK, to make this RV-related, I've spent too long yesterday reviewing what my pitot options are all so I can drill a hole (or not) in the ?$^%& wing skin! However, this question has bugged me for a while now.
If you look at the equation for dynamic pressure, p = 1/2.rho.v^2, if v is negative, you'll achieve a negative pressure (or vacuum) of equal magnitude which you can use for your signal, plus insect infestation and icing would likely be less of a problem
Does anyone know why it isn't done?
