Folks I have my pitot and static currently mounted about 3" below the left wing and above but in line with the outer tyre edge of the main wheel leaving about 7 inches of clearance or less when I put on the spats. The airspeed indicator seems to under the GPS by about 12 knots in nil wind conditions at 1000 feet at speeds from 60 to 130 knots. Whilst this doesn't really matter aerodynamically once you have established a set of numbers to fly by, it helps to be as accurate as practical for comparision purposes and less so for navigation (conversion to TAS etc).
I wish to move the pitot and static away from the wheel to both minimise any air disturbance from it (and maybe prop wash) but also to prevent it getting smashed up by the tyre/spat in the event of a heavy landing. I was thinking of re-mounting it on the outer wing stub rib and extending it forward along the chord line about 8 inches from the leading edge. My question is will this be enough? Have other netters similiar instances to relate and what were your solutions? I know the new location will be more prone to damge from curious onlookers etc. on the ground. PS: I've replaced my ignition switchs and now have a 1/2 volt gain across the terminals....just joking :-) Regards John The Martindale Family 29 Jane Circuit TOORMINA NSW 2452 AUSTRALIA phone: 61 2 66584767 email: [email protected]
