Definition
A turn flown at a bank angle of approximately 20 to 45 degrees, in which the airplane maintains the bank without the aileron input required to hold it. Below this range, the airplane tends to roll back toward wings-level on its own; above it, the airplane tends to overbank and steepen the turn if the controls are released.
Plain English
A turn with a moderate amount of tilt, where the airplane stays at that tilt by itself without you having to hold the control wheel into or out of the turn.
Context Anchor
Seen in airplane maneuver descriptions, including stall demonstrations and turns in the traffic pattern.
Derivation
“Bank” originally refers to a sloped or raised side, like the bank of a river. In flying, it helps describe the airplane being tilted sideways, as if one wing is lower and the other is higher while the airplane turns.
Why Pilots Care
The bank category determines how the pilot must use the controls. In a medium-banked turn the ailerons can be neutralized once established, freeing the pilot to focus on pitch, rudder coordination, and outside scanning. Knowing where this band sits also helps the pilot recognize when a turn is drifting into shallow or steep territory and requires a different control input.
Intuition Check
“Medium” does not mean a casual or approximate turn here. It means a moderate bank angle used to describe how much the airplane is tilted during the turn.
Example Sentence 1
Once established in a medium-banked turn to the left, the student released aileron pressure and the bank held steady at 30 degrees.
Example Sentence 2
Students first practice medium-banked turns to develop coordination before attempting steeper banks.
