Hi, I have read in S/Bs manual about FMS and I have also seen screenshots that is is possible to have FMS controlling your airspeed anf for this reason you have to activate the "Velocity nav" option in the FMS autopilot screen. My problem is I do not have that option in the specific screen. The rest are working fine (A/P couple, Lateral nav, Altitude Nav) but the Velociyt nav is just missing. The version of S/B I am using is 2.3.5 and my simulation is FS2002. Any ideas?
