Automatic Flight
The Autopilot and Flight Director system allows automatic flight in both Command and Flight Director modes. In Command mode,
the autopilot is controlling the aircraft pitch, roll and thrust. In Flight Director mode, the autopilot generates control commands and
moves the Flight Director bars on Primary Flight Display to guide the pilot. Autothrottle system operates thrust levers to adjust
thrust according to engaged autopilot modes.
Autopilot has three channels, Pitch, Roll, and Thrust channels. Some autopilot modes control only one channel, while other modes
control two channels.
The Roll modes are single-channel. They include:
HDG HOLD
Commands the autopilot to roll wings level, and hold the heading existing when reaching zero bank.
HDG SEL
Turn to and maintain heading selected in MCP HDG/TRK window. The bank angle during the turn is either
automatic or can be manually set using the bank angle selector.
TRK HOLD
Commands the autopilot to roll wings level, and hold the track existing when reaching zero bank.
TRK SEL
Turn to and maintain track selected in MCP HDG/TRK window. The bank angle during the turn is either automatic
or can be manually set using the bank angle selector.
LNAV
Lateral navigation. Follow FMC-generated roll commands to fly the active route.
LOC
Capture and follow the localizer.
Basic Pitch modes are single-channel too:
ALT HOLD
Captures and holds the altitude existing when the mode was engaged. This mode is also engaged when in V/S
or FLCH mode and airplane reaches the altitude selected in MCP Alt window.
V/S
When engaged, opens the VS / FPA window with present vertical speed, and maintains this speed.
The vertical speed can be adjusted using the VS / FPA thumbwheel.
FPA
When engaged, opens the VS / FPA window with present flight path angle, and maintains this angle.
The flight path angle can be adjusted using the VS / FPA thumbwheel.
G/S
Captures and holds the glideslope.
Other Pitch modes are two-channel and control both pitch and thrust:
FLCH
Starts climb or descent towards the altitude selected in MCP Alt window. If climbing, throttles maintain Climb
thrust, if descending, throttles are moved to idle. The aircraft pitch is adjusted to maintain the speed selected in
MCP IAS/Mach window. The plane nose is lowered to accelerate and rised to decelerate.
VNAV
Vertical navigation. Both pitch and thrust are controlled to follow the vertical profile and speed settings generated
by FMC for the active route.
Two thrust modes are also available, which are
SPD
Autothrottle adjusts thrust to maintain the speed selected in IAS/MACH window.
THR
Autothrottle maintains reference thrust selected in FMC and shown on EICAS display.
The APP mode controls both pitch and roll to follow localizer and glideslope for an ILS approach.
The Autopilot modes are switched from the Mode Control Panel (MCP), pictured below.

When LNAV mode is armed, it can be
disarmed with second push. LNAV mode can
be disengaged by selecting other roll mode.
Automatically disengages when LOC mode
engaged and localizer becomes alive.
When using VNAV, the normal procedure is to set your cruise altitude in MCP Altitude window before takeoff, and reset this altitude
to zero or MDA when approaching the Top of Descent point. Until a lower altitude is not selected, the descent will not be started.
When VNAV mode is active, as in other vertical modes, the MCP altitude window is a «restriction». When aircraft climbs or
descends in VNAV mode and reaches the altitude selected in Alt window, it levels off and pitch mode displayed on PFD changes to
VNAV ALT. Thus, the altitude window can be used for example when flying under ATC control. If ATC clears you to climb to an
altitude lower than cruise altitude set in FMC, all you need is to select your clearance in MCP ALT window. Aircraft will level off
when approaching this altitude. As soon as another clearance is received, enter the new cleared altitude or cruise altitude in ALT
window and Push the Altitude selector knob to resume the climb.

Flight Management Computer
The Flight Management Computer (FMC) is the primary means of navigation and automatic flight along the route.
The FMC allows entry of flight route consisting of a number of waypoints. The route is displayed on the Navigation Display (ND), and
can be flown either automatically, using the LNAV (Lateral Navigation) autopilot mode, or manually. The legs between route waypoints
are calculated as Great Circle paths, ensuring the minimal leg distance. The route can be manually entered by specifying the route
waypoints, or imported from existing FS2000 flight plan. The route can be modified at any time by inserting or deleting waypoints.
The FMC contains a complete, current real-world AIRAC navigational database which includes airports, runways, navaids, waypoints,
and SID and STAR procedures.
You can select desired SID (Standard Instrument Departure) and STAR (Standard Terminal Arrival) procedures for Departure and
Destination airports. Selected SID and STAR waypoints will be added to the route and will be displayed on the ND. These procedures
will be flown according to any special routing defined for such SID and STAR.
The FMC calculates optimal Vertical (altitude) and Speed profiles for Climb, Cruise, and Descent stages of enroute flight. This
calculation accounts for any altitude and speed restrictions defined for route waypoints, and for speed restrictions and transitions set
for climb and descent. FMC automatically computes the Top of Descent (TOD) point which allows the descent on idle or minimal thrust
to minimize the fuel consumption. The Economy speeds for all flight stages are calculated based on entered Cost Index.
The vertical and speed profile can be flown automatically using the VNAV (Vertical Navigation) autopilot mode. The crew can level the
aircraft off at any assigned altitude without leaving the VNAV mode by selecting the altitude in MCP ALT window. Additionally, the FMC
speed commands can be overriden by pushing the MCP speed selector knob and selecting different speed.
The FMC allows for performance management. It computes the takeoff V-speeds, thrust settings, optimum and maximum cruise
altitudes, landing reference speeds etc based on fuel quantity, entered Zero Fuel Weight, atmospheric conditions and other factors.
Based on computed optimum altitude, the FMC automatically calculates Step Climb points to minimize fuel consumption by climbing
at higher altitudes as fuel burns and aircraft weight reduces.
The FMC allows the flight progress monitoring by estimating the time of arrival and remaining fuel on next waypoint and destination.
Holding patterns can be automatically flown in LNAV mode. The crew can define a hold with any parameters, at any enroute or offroute waypoint, or at present position. The FMC will automatically choose the correct hold entry procedure depending on entry course
and holding pattern orientation.
The FMC automatically tunes the NAV1 and NAV2 navigation radios to the two closest VOR stations. The crew can override this
autotuning and tune any NAV radio by entering the new frequency or station identifier. When approaching the destination airport and
an ILS-equipped runway is selected, the ILS frequency and front course will be automatically selected on NAV1 radio.
The FMC is controlled using the Control Display Unit (CDU), accessed by clicking on panel FMC icon or pressing Shift-5.
