Hey folks
On the performance inflight table (airspeed unreliable/turbulence penetration) section you have climb 280/0.76 flaps up,cruise 280/0.76 flaps up,descent 280/0.76 flaps up tables,as per the FCOM 1 it further says 280/0.76 speed is only used as turbulence speed for the climb and descent for cruise use N1 turb,but the table for cruise says 280/0.76 for cruise with flaps up,can anybody try and clarify it to me?
