Synoptic Display
Synoptic displays are provided as a means of assisting the flight crew in rapidly
understanding the status of the airplane systems. However, crews should not rely
solely on the displays for determining airplane status. The flight crew is
encouraged to select a display at any time they feel it is the most efficient way to
get desired information. Synoptic displays should only be used as necessary to get
the desired information and then turned off. The clarity and simplicity of
displayed information enable the flight crew to obtain necessary information from
a brief scan.
Note: Crew procedures and actions are not dependent on use of synoptic displays
nor is reference to synoptic displays included as a component of flight crew
procedures.
If the flight crew elects to use synoptic displays in conjunction with
accomplishment of procedures, they must assure no distraction from the intended
task results. This is particularly true when accomplishing non-normal procedures.
Under certain conditions, system faults can result in missing synoptic information.
Therefore, decisions regarding non-normal situations should be based on EICAS
messages and other flight deck effects and indications. In every case where a
non-normal procedure results in a need for recall items, they should be completed
before selecting a synoptic display. Accomplishment of necessary procedures
should take priority over use of synoptic displays.

Flap Usage
For takeoffs, when conditions permit, consider using larger flap settings to provide
shorter takeoff distance.
During maneuvering for an approach, when the situation dictates an earlier than
normal speed reduction, the use of flaps 15 or flaps 20 with the gear up is
acceptable.
For normal landings, when conditions permit, use flaps 30 to minimize landing
speed and landing distance. Flaps 25 provides better noise abatement and reduced
flap wear.
Flap - Speed Schedule/Maneuvering Speeds
The flap maneuvering speed schedule provides the recommended maneuvering
speed for various flap settings. When the recommended maneuvering speeds are
followed, the schedule provides full maneuvering margin or at least 40° of bank
capability (25° angle of bank and 15° overshoot) to stick shaker.
The schedule provides speeds that are close to minimum drag and in climb are
close to maximum angle of climb speed. In level flight it provides relatively
constant pitch attitudes and requires little change in thrust at different flap settings.
Flap Maneuvering Speed Schedule
777-200 - 777-300ER
The flap maneuvering speed schedule is based upon VREF 30 and provides full
maneuver margin to stick shaker at all weights.
787-8
The flap maneuvering speed schedule is based upon TBD and provides full
maneuver margin to stick shaker at all weights.
777-200 - 777-300ER

During flap retraction/extension, selecting the next flap setting should be initiated
when reaching the maneuver speed for the existing flap position. The airplane
should be accelerating when flaps are retracting to the next position. During flap
retraction, at least adequate maneuver margin or 30° of bank capability (15° angle
of bank and 15° overshoot) to stick shaker is provided at the flap retraction speed.
Full maneuvering capability or at least 40° of bank capability (25° of bank and 15°
overshoot) is provided when the airplane has accelerated to the recommended flap
maneuvering speed for the selected flap position. During flap extension, selection
of the flaps to the next position should be made prior to decelerating below the
recommended flap speed for the current flap setting.
The maneuver speed for the existing flap position is indicated by the numbered
flap maneuvering speed bugs.
