Wonder why, standard rate only applies up to 180kts, a speed which is well below clean speed for most jets, especially those used in commercial transport services.
Hello,
This is due to bank limitations.
With a rough approximation 15%TAS = Bank rate 1.
Flying 180KIAS not too high (TAS increases) would give already 27° bank for rate 1. Close to max bank in commercial transport.
