I've heard it does it. Is it a design feature or just something that happens? 2 autopilots = fail passive such that a disconnect leaves the a/c in a trimmed state and no abrupt manoeuvres. I assume it's because the 2 A/P's talk to each other and compare notes, which is a requirement for LVO. I assume, therefore, a single autopilot can autoland in >Cat 1 but is not approved for LVO's. If that is the case why is it not a commonly taught technique, and is ti approved? An autoland in marginal Cat 1 might sometimes be useful; or other scenarios.
