Does the D10A need a dedicated remote compass to provide a reliable headng if the D180 is no longer on the DSAB?

1/ Tee the pitot, static & AOA lines. One instrument failure will not affect the pressure in the lines (unless its a large leak in the pressure transducer - unlikely) however a pitot-static failure will affect both instruments. Most people seem to think dual pitots excessive....
2/ The D10A will either need its own remote compass or would have to get heading reference off its internal magnetometer if the D180 goes off the DSAB. Most people have trouble calibrating the internal magnetometer as there's so much magnetic stuff & wires around the instrument panel.
