At what altitude is 1/2 Bank automatically engaged?

• A. 25,000 Feet
• B. 28,000 Feet
• C. 31,600 Feet
• D. 34,000 Feet

Answer: (C)

At high cruise, the flight control system tames roll by using a gentler bank mode to keep handling stable and reduce stress on the airplane. The aircraft automatically limits bank to half of the commanded amount once you reach around thirty-one thousand six hundred feet. This threshold is chosen because, in thinner air with less aerodynamic damping, large bank angles can be harder to control smoothly, so halving the bank helps maintain a steadier, safer turn and protects the structure and passengers from abrupt roll motions. Below that altitude, normal bank limits apply, so the autopilot can command the usual bank angles without this automatic restriction. If you’re hands-on, you can override with manual input, but above the threshold the automatic half-bank protection will constrain the turn.
