The Autothrottle will not (or at least it shouldn't) exceed the maximum speed for the current flap setting regardless of whether you are using VNAV or not. I don;'t think you are supposed to use the flaps above 10,000 feet anyway.
Besides that, I usually start raising the flaps once the 757 is 1,000 feet AGL (Above Ground Level).

The A/T will try to maintain what is set in the speed select window or what you have entered in the computer in VNAV.

Don't arm anything on takeoff, just fly the aircraft. Each airline or operator had different altitudes for clean-up after takeoff. Most were out of 1,000 feet.

On takeoff, you would advance the throttles and select EPR. The thrust would go to what is selected in the TMSP (thrust mode select panel). After 80 knots the throttles go into THR HOLD. EPR is replaced with thrust hold. The throttles can be moved in THR HOLD to make adjustments.

After takeoff, at around 1,000 AGL, press CLB on the TMSP to change the thrust to climb thrust. You can press FLCH and set the speed to 250 knots. As the speed increases, retract the flaps on schedule. You could also engage VNAV and it will program the speed as well.



Don't engage the autopilot unless the plane is stable and in trim and in the real plane ALWAYS be ready to press the disconnect button if the autopilot tries to do a hard-over. Fly the plane and trim the elevator force out. Steer the plane on course manually or engage the autopilot and either steer it with HDG or LNAV. If you are closer to the magenta line before selecting LNAV the autopilot action will be smoother.

All the buttons that have a LINE connected to the speed window are speed modes. So, SPD, VNAV & FLCH will all put the auto throttles in speed mode. Notice EPR & LNAV are NOT speed modes!
