B737NG F/D's on Initial Climb Out.
Automatic Flight Takeoff and Climb
There are certain times at LIFT-OFF during the initial climb out, the F/D pitch command at times indicates 20 degrees of pitch instead of 15. And latter reduces to 15? Is this something to do with the Rate of Rotation.
Also is it safe to pitch up to 20 degrees, following the F/D guidance ?
