You asked about commercial aircraft in general, so I will give an answer from that point of view. Is there any obvious warning when auto-pilot is disengaged? Yes, both visually as flashing lights, and aurally. Furthermore, the lights and tone does not go away until a second confirmation is received from the pilot. For example, pushing the button on the ...

The Boeing 737 allows a mode called control wheel steering (CWS). The A320 doesn't. For what is CWS, see: Is it possible to disengage only one axis of a two-axis autopilot? The wording on Wikipedia doesn't emphasize this point; however, the final report does. The pilots may also manually control the aircraft in a normal manner with the control wheel and ...

If your talking about standard rate turns, those are not really practical in large commuter aircraft. As true airspeed increases the maximum turn rate decreases when the bank angle is limited to a comfortable level of less than 30 degrees of bank. So please make this question more specific, which airplane category are you talking about? Usually the ...

To my surprise, the FAA clause was added in 2006 after the 2004 notice of proposed rulemaking (NPRM) No. 04-11. Three NTSB recommendations were part of the reason, with the earliest from 1992 (A-92-035). (...) autopilot failures that can result in changes in attitude at rates that may be imperceptible to the flightcrew (...) From the NPRM: This ...

In all the jets I fly, the autopilot will always bank at 25 degrees. It doesn't worry about standard rate turns. As others have pointed out or alluded to; a standard rate turn with airspeed above 180 KTAS requires larger than comfortable bank angles. The autopilots also have a half bank feature to limit banks to 13 degrees. Most often pilots will use ...

The amount of bank is that which is required to achieve the standard "Rate 1" or 2 Minute turn, being 3 degrees heading change per second, which takes you in a full circle in 2 minutes. This is a universal protocol for turns in the IFR world. This varies with true airspeed (the faster you're going the higher the bank angle required to turn at 3 deg/sec) ...

For non FVW airplanes: Yes it will disengage if certain pitch and roll attitudes are exceeded. When it disengages, the controls are "let go" if the A/P was applying an input at the time, and the control column will move to whatever its natural trimmed state is at that time if the elevator is manually operated with trim tabs. If the airplane has ...

I don't believe anyone could hand fly something that precise. A series of waypoints could be entered in the flight plan in a "connect the dot" manner, then the autopilot could be put in NAV mode to fly the pattern. Nothing that difficult about it though, it would just take some time. If they are at 10,000 feet this could be done under VFR, in which case ...
