April 3, 201610 yr Hi, In many videos on line, we can see the pilots pushing the throttle forward when taking-off, hand staying on the throttle till V1. Unlike Airbus which has a notch, how far should 737 NGX pilots push forward? Depending on the N1 mark or the auto-throttle system has motor or something which "takes" their hands forward? Thanks.

April 3, 201610 yr Until approx 40% N1, then if the engines are stabilised, ie both producing the same thrust, press TO/GA button and the A/T will physically move the levers to the FMC calculated T/O thrust. Peter Schluter
April 3, 201610 yr the auto-throttle system has motor or something which "takes" their hands forward Correct. In the real 737 you push the TOGA button on the throttles and in the PMDG 737NGX you can also use the hidden clickspot on the MCP or press CTRL+SHIFT+G to trigger the takeoff thrust, provided you armed the autothrottle. The throttles will then be driven forward automatically. The reason why you still keep your hand on the throttles is in case you want to abort the takeoff. Read through tutorial 1, it explains the takeoff procedure very well.

Frank Tien On the real 737, the throttles are automatically advanced by electric servo motors when the autothrottle engage switch is pressed. The pilot's hand follows. It is standard practice on virtually all aircraft for the pilot to keep their hand on the throttles until reaching V1, so that the throttles can immediately be pulled back to idle in case an abort is required. Though some home cockpit builders have invested in motorized hardware throttle levers, for most of us, the autothrottle is only implemented in software. It is still a good idea to keep ones hands on the power levers until reaching V1, because an aborted takeoff is certainly possible - especially with add-on aircraft that have the option to simulate engine failures.
