Plain English Meaning

The wings stay tilted at the same angle the whole time. You set the bank, then leave it alone while you work the pitch or power.

Full Definition

A bank angle that is held steady — neither increasing nor decreasing — throughout a portion of a maneuver. The airplane remains at a fixed angle relative to the horizon while other parameters such as pitch, airspeed, or altitude may change.

Context Anchor

Used in chandelle training, especially when describing the first half of the maneuver, where the airplane turns while the bank angle is held steady.

Derivation

‘Constant’ comes from the Latin constare, meaning ‘to stand firm’ or ‘stay the same.’ ‘Bank’ refers to tilting the wings. Together: the bank stays put.
