The AFCP bank protection is automatically activated above which altitude?

The AFCP bank protection is automatically activated above which altitude?

• A. approximately FL300
• B. approximately FL360
• C. approximately FL350
• D. approximately FL400

Answer: (C)

AFCP bank protection is a safety feature that limits how far the airplane can roll once you’re in the high-altitude portion of flight. The idea is that at very high altitudes the air is thinner, handling margins are tighter, and you don’t want a large bank to develop from autopilot or control inputs that could push you past safe limits. So the system automatically kicks in to cap bank angles when you climb above a certain altitude. For this airplane, that protective behavior starts around 35,000 feet, i.e., approximately FL350. Above this level, the AFCP will constrain bank to a safe limit to help maintain stability and protect against overly aggressive rolls in the high-altitude envelope. The other altitude options would either trigger too early or too late for this model’s protection scheme, so FL350 is the closest and correct threshold.
