You are welcome PT6Driver. Except you are only a little bit right.
Pitch Modes
•TO/GA – Takeoff Engaged for takeoff by turning both F/D switches ON and pushing either TO/GA switch. Both F/Ds must be ON to engage TO/GA prior to starting takeoff.
The AFDS commands pitch attitude in the following order:
•10 degrees nose down until 60 knots IAS
•15 degrees nose up after 60 knots IAS
•15 degrees nose up after lift–off until a sufficient climb rate is acquired.
Then, pitch is commanded to maintain MCP speed plus 20 knots.TO/GA can also be engaged for takeoff with F/D switches OFF if a TO/GA switch is pushed after 80 knots IAS below 2000 feet AGL and prior to 150 seconds after lift–off.
What happens in weather conditions like this where the wind is a violently strong and gusty rapidly increasing headwind is the FD directs pitch for MCP speed plus 20 and at go around thrust this will command a pitch attitude that is unsustainable once the increasing headwind goes away...and it will.
15 degrees is good and you don't need that much. Where pilots bone this up is following a FD up to oblivion. The FD simply can't keep up with the dynamics involved. The answer is 15 degrees as long as you have a good climb going and if max flap speed become a problem pull the damn power back.
Everyone is gonna have to face it. We have to know how to fly. Automation isn't always good to us. It's a great tool used appropriately.
