Re: How often are takeoffs with manual thrust performed?

On the ‘bus - all the time. Throttles (ahem, ‘thrust levers’) are essentially manual until climb.

On Boeings - A/T is used for takeoff unless it is inop. As GalaxyFlyer said, throttles may be set manually, or automatically. The end result is the same.

Re: Boeing 787-9 gets range boost.

At low weights is the key word. A 787-9 flying long distances won't be at low weights. The last thing you want at MTOM after an engine failure is for the remaining engine to deliver less power. IMO, it's a safety feature, not a performance booster. Well, at high weights Vmc is generally not an issue.

Re: Boeing 787-9 gets range boost.

As Zeke correctly wrote, you can't just increase thrust. Controllability and rudder size play a role. The 787-10 can have more powerful engines because it is longer, so the rudder acts on a longer arm. I for one think Zeke is right about this being a thrust bump for certain conditions, allowing the...
