input to the co-pilot’s side will not result in any message annunciation.
• Autopilot performance when coupled to the side with a failed TAS input will be
significantly degraded in other than approach phases of flight.
• FMS derived wind vector and head/tail wind and crosswind displays will be
unreliable.
