You really are a crack up.
Sometimes you have legit questions and sometimes your posts,such as this one just makes me wonder.
If you reach 251 kts on the NG,all spoilers(including ground spoliers) deflect and pitch up is commanded so you dont bust atc speed restrictions and protect yourself from the odds of a bird strike.
Window heat is also increased.
The NG is really top
Avoid flying at high speed for a long time in areas of bird activity is recommended,if the bird is too big you can always duck under
Aircraft management is good,saving gas is even better,high speed is not required for either.
