and probably by a number of others as well.
Boeing is one upping Airbus in the technical wars of how to design a better airliner. Now we can have competitive pressures to add to pressures from regulators to improve the existing Airbus design.
Airbus already has backup speed scale - BUSS - which is effectively a synthetic airspeed from same source parameters as the Boeing one.
How many types is Boeing implementing this on ? I think BUSS is available on everything later than 320, and mandatory on 380 onwards ?
