[Peer 0]

Concerning all PSS A320/330/340 models.Why is the indication in PFD and Nav display showing only 330 kts (as Vmax) in selected as well as in managed mode by MCDU?On PFD after 330kt the red line (like Alpha protection) is present.How can I increase the speed again to 460 kts?Many thanks for an answer, Paul

What you see in the PFD is Indicated Airspeed "IAS". Max IAS on the A340 is 330kts. Groundspeed and True Airspeed is something else./Stellan
