They are replaced in this aircraft by stopwatch buttons, much more useful! When the flap is retracted, the folding nose section rotates and is stored under the wing. Automatics The original purpose of the glareshield panel was to put the most important warning lights in the most attention grabbing place.

This function could be used to control the pitch of the aircraft with trim say in the event of a jammed elevator. In any series ofif an asymmetry is detected, hydraulic power is removed.

It is powered by hydraulic system B. A full list of all FCC updates detailing their features is available in the book. They comprised three panels, the autopilot centre and one for each flight director sides. Eliminated the cause of a disconnect which may occur when flying dual channel autopilot go-arounds on the Alpha submode.

A raised shield was also fitted around the aft end of this panel to prevent inadvertent movement of the trim controls. They have the same sequencing as the classics. Flap load relief function active from flap 10 or greater.

So the yaw damper is not required for dispatch, however it is fitted for passenger comfort. It includes the following changes: There are Boeings comments upon how the new MCP was designed: This function is available as an option.

Leading Edge Devices Are comprised of 4 Krueger flaps inboard of the engines and 6 slats outboard of the engines. The modification slightly extends and lowers the aft segments of the trailing edge flaps thereby increasing wing area, camber and importantly lift-to-drag ratio.

There are balance tabs and balance panels on both elevators. This indicates that the standby rudder PCU is pressurised. The reason for the limitation is simple; Boeing does not demonstrate or test and therefore does not certify airplanes for operations with flaps extended above 20, feet.

Note, due to inconsistencies associated with the arming of VNAV prior to takeoff, Boeing released the reference a ops manual bulletin instructing flight crews to not attempt arming VNAV on the ground prior to takeoff.

Speed trim is a dual channel system.The flight controls are powered by redundant hydraulic sources; system A and system B.

Either hydraulic system can operate all primary flight controls. The ailerons and elevators may be operated manually if required (Manual Reversion). Mar 08,  · Truly Interactive NG Systems Software. Highly accurate system models with full interactivity.

The Adv mode control panel has remained virtually unchanged through to the NG’s. The differences between this Adv MCP and the + MCP are: The FCC is the brains of the Digital Flight Control System (DFCS) and like any other computer, its software is being improved (and debugged!) all the time.

Boeing • Tagged b eifis. There will be looked at the flight control system of the Boeing NG and the flight control system of the Airbus A () after that a comparison between the conventional system and fly-by-wire system (). B NG flight control system. This section will discuss the flight controls of the Boeing NG.

At first the hydraulic system of a Boeing (a) is necessary for the working of the primary(b) and secondary flight controls (c) The Boeing has three hydraulic systems: A, B and standby.

The standby system is used when there is. Sep 12,  · Flight and ground spoiler deployment on landing: Spoilers / Speedbrakes.

Flight spoilers (2 -1/2/3/4/; 4 -NG’s) augment the ailerons and are powered by hydraulic system A (inboard) & B (outboard). Spoilers will continue to operate with speedbrake deployed. Ground spoilers are also from hydraulic system A.
