Definition
A rollout from a bank in which the airplane's bank angle is reduced at a steady, uniform rate so that wings-level attitude is reached at a planned, specific point — typically used in the second 90 degrees of a chandelle, where the pilot rolls out of the bank at a constant rate while the pitch attitude is held constant.
Plain English
Coming out of a bank smoothly and evenly, taking off the same amount of bank each second, so the wings become level exactly when you want them to.
Context Anchor
Encountered while learning or practicing the chandelle, especially as the airplane is completing the second 90 degrees of the maneuver.
Derivation
“Constant” means unchanging, from a Latin word meaning “standing firm.” “Rate” means how fast something changes over time. In flying, “rollout” means rolling the airplane back out of a banked turn, not the roll after landing. Together, the phrase means the bank is removed steadily over time.
Why Pilots Care
Prevents overshooting the heading, loss of coordination, or altitude deviation when completing the maneuver.
Intuition Check
Constant does not mean holding the same bank angle here; it means holding a steady pace while removing the bank. Rollout does not mean the ground roll after landing; it means coming smoothly out of the turn.
Example Sentence 1
During the second 90 degrees of the chandelle, the pilot held pitch steady and used a constant rate rollout so the wings leveled right at the 180-degree point.
Example Sentence 2
Maintaining a constant rate rollout keeps the aircraft coordinated and prevents rolling out too soon or too late.
