New FAA SAFO 17007! interesting reading material!
An extract:
An air carriers line operations policy should permit and encourage manual flight operations and should
incorporate the following:
1. Encouragement to manually fly the aircraft when conditions permit, including at least periodically,
the entire departure and arrival phases, and potentially the entire flight, if/when practicable and
permissible.
2. When deciding to fly manually, crews should apply basic threat and error management principles
and take into account the various factors affecting operational workload. Factors to consider
include:
Weather conditions, terrain, and/or other environmental threats
Time of day
Psychological and/or physiological factors
Level of crew experience
Traffic density
Condition of the aircraft, and/or any non-normal conditions
Air Traffic Control and/or instrument procedural challenges
Any other operational threats

aircraft equipage, e.g.,
FD on, AP off, AT on
