"We have some very smart computers on board, charts the manufacturer provides us plus decades of experience that provides us with guidance as to when we should initiate a climb and what altitude will result in the greatest fuel savings for kilo/pound/ton of fuel consumed for distance traveled given the weight of the jet given the winds and temperatures at altitude on that day."
Thanks again Northbeach, so in reference to the above, does the computer itself actually commence the climb without any input from the crew?, or does the pilot in control at the time take over when prompted by the computer and manually adjust the aircraft settings for climb?
Thanks
