Coming off Boeings onto the A320/330/340, I have to say that the standby speed indication on the Airbus was a nice change. The B777 didn't often have AoA displayed on the PFD, so in the same case, the only rational option was to use a differential between attitude and FPV to ascertain AoA. In around 2010 or so, that was pushed out of the available options, with Boeing recommending not to use the FPV in the case of a loss of all airspeed due to input into the display being degraded. Thereafter, you have GS and not much else other than reverting to the NNCL and the gross unreliable airspeed tables, which at least end up pointing you at planet earth but are hardly a precision system. At least with the 787 that became less of an issue, but, Airbus, your standby speed was a nice solution.
