My problem has nothing to do with the excessive pitch up.

I prefer to select the speed myself. However, it is not the pitching up or pitching down that bothers me. It is the "bouncing" that occurs sometimes when I do this. I do not believe that the 777 (or any airliner for that matter) should "bounce" up and down quickly at any time, particularly in calm conditions with a wind speed of 1m/s, and zero gusts.

I generally increase the speed to 200 knots during the climb when I pass through 2500 feet. The aircraft pitches forward to accommodate this. Perfectly normal.

In short, I have my own way of doing things, but the aircraft should still behave in a manner that obeys the laws of physics!

To confirm what you mentioned, this is an intermittent behavior and is not limited to the takeoff/climb phase.

As you correctly stated, “I have my own way of doing things.” That is perfectly reasonable. Pilots develop their own techniques and preferences, and the 777 allows for that. However, regardless of the technique being used, the aircraft's response should remain consistent with the aerodynamic and flight-control characteristics of the real airplane.

What concerns me is not the initial pitch response when a new speed is selected, but the rapid pitch oscillations or “bouncing” that can sometimes follow. In calm conditions, particularly with only 1 m/s of wind and zero gusts, that type of rapid, repeated pitch response would not be representative of the real 777.

I would suggest making a short video demonstrating the behavior. That would make it much easier to identify exactly what is occurring and under what conditions.

If what you are describing is the same small, rapid pitch oscillation I have seen, then I recognize the behavior. Similar micro-oscillations have been present in the simulator environment going back to FSX. From my experience with the real 777, this is not representative of normal aircraft behavior and is something that should be addressed in the flight model/control-law implementation rather than attributed to the pilot's technique.

As others have mentioned, the 777 flight model hasn't been right since it came out on older platforms. The flight characteristics aren't too accurate and don't even get me started on the taxiing 🤣

Taxiing in the 777 feels OK to me. It is the 737 that can feel a bit "shopping trolley" when making subtle adjustments during take off and landing. However, even that feels generally fine to me 95% of the time.

For taxing, it's also in its own code, but it can be helped a bit by changing to this

[CONTACT_POINTS]

point.0 = Name:Wheel_Central#Properties:1,70.3,0,-13.72,1500,0,1.791,55,1.401,1.4,0.450,13.5,13.5,0,485,0,5

 

max_speed_full_steering = 65

max_speed_decreasing_steering = 102

min_available_steering_angle_pct = 0.02

steering_time_constants = 6,9

allow_stopped_steering=1

spring_exponential_fix = 1

Thanks I'll give it a try 🫡
