Min engagement AP height is defined as what?

• A. 200 ft
• B. 400 ft
• C. 600 ft
• D. 800 ft

Answer: (B)

Autopilot engagement height is the minimum altitude above the surface at which you may arm or engage the autopilot after liftoff. On the ERJ 175, this minimum is four hundred feet above the ground. Why this value fits: engaging the autopilot at about four hundred feet gives a safe buffer to ensure the aircraft is in a stable climb, the configuration is correct, and airspeed is established before automation takes over. It lets you confirm that flaps/slats are retracted as appropriate and that you have enough altitude to detect and correct any issues without being pressed to react in a very low, high-workload phase. Lower values reduce the margin for manual correction and increase risk if something isn’t trimmed or configured properly; higher values unnecessarily delay the benefits of automation during the early climb. In short, four hundred feet provides a practical balance between keeping the pilot in control during the critical climb and leveraging automation once a safe, stable path is established.
