What type of turn is characterized by a bank angle less than 20 degrees?

A turn characterized by a bank angle of less than 20 degrees is known as a shallow turn. This type of turn is generally used for maintaining altitude and minimizing changes in airspeed and flight path. In shallow turns, the aircraft’s attitude change is subtle, which helps to ensure a smooth transition through the maneuver without significant increases in load factor or stall risk. This is particularly important during basic flight maneuvers as it allows pilots to maintain better control of the aircraft, ensuring stability while navigating the airspace safely. These characteristics make shallow turns practical for various flight operations, especially when gradual changes in direction are necessary.
