Where can the degrees of bank be found during flight operations?

The degrees of bank during flight operations can be effectively observed on the attitude indicator. This instrument displays the aircraft's orientation relative to the horizon, allowing pilots to see whether the wings are level or if the aircraft is banked to the left or right. The attitude indicator provides a visual representation of the aircraft's pitch and roll angles, which are crucial for maintaining control during turns and maneuvering.

In contrast, while the vertical speed indicator measures the rate of climb or descent, it does not indicate bank angles. The heading indicator shows the aircraft’s direction relative to magnetic north and does not provide information on the degree of bank. The altimeter measures altitude but, again, does not relate to the aircraft's bank angle. Thus, the most relevant instrument for determining the degrees of bank is the attitude indicator.
