Well in real life the pilot sets he throttle to TOGA or FLEX settings for takeoff if the plane has that option. And in small GA prop planes like I fly you use full throttle for takeoff and climb. Dash 8 is a little different though.
90%-95% Is what I would use.
Yeah for jets full throttle isn’t normal and can cause damage. Props work differently. Still Dash 8 isn’t made for full throttle usage on a normal basis. You’re correct though.
My thottle is always 100% when I take off.
