Q

TO/GA (Takeoff) (Pitch Mode)

A

(Pitch Mode)(Takeoff)
Engaged for takeoff by turning both F/D switches ON and pushing either TO/GA switch. Both F/Ds must be ON to engage TO/GA prior to starting takeoff.

The AFDS commands pitch attitude in the following order:

  1. 10 degrees nose down until 60 knots
  2. 15 degrees nose up after 60 knots
  3. 15 degrees nose up after lift-off until a sufficient climb rate is acquired. Then pitch is commanded to maintain MCP speed plus 20 knots. TO/GA can also be engaged after takeoff with F/D switches OFF if a TO/GA switch is pushed after 80 KIAS below 2,000’ AGL and prior to 150 seconds after lift-off.

2. inflight below 2,000’ RA with flaps not up or G/S captured.
3. not in takeoff mode
4. either F/D ON or OFF

When engaged, the F/D’s command roll to hold the ground track, and 15 degrees nose up pitch. After reaching a programmed rate of climb, pitch commands the target airspeed for each flap setting based on maximum takeoff weight calculations.

35
Q

A

(Roll Mode)(As Installed)

(Armed) The AFDS is armed (prior to takeoff) to engage LNAV at 50’ RA.

37
Q

LNAV (Armed)(Landing)(Roll Mode)

A

(Roll Mode)(As Installed)

(Armed) in the approach phase and a missed approach exists in the flight plan.

38
Q

LNAV (Engaged)(Roll Mode)

A

(Roll Mode)(As Installed)

(Engaged) The AFDS intercepts and tracks the active FMC route. Either of the following capture criteria must be met:

  1. on any heading and within 3 NM of the active route segment.
  2. if outside 3 NM of active route segment, airplane must be on an intercept course of 90 degrees or less and intercept the route segment before the active waypoint.
39
Q

HDG SEL

A

(Roll Mode)(As Installed)

The airplane is turning to, or is on the heading selected in the MCP Heading display.

40
Q

VOR/LOC (Armed)(Roll Mode)

A

(Roll Mode)(As Installed)

(Armed) AFDS is armed to capture selected VOR or LOC course.

41
Q

VOR/LOC (Engaged)(Roll Mode)

A

(Roll Mode)(As Installed)

(Engaged) AFDS tracks selected VOR course or tracks selected localizer along the inbound front course bearing.

42
Q

CWS Engage Switch selected

A

Engages the A/P pitch and roll axes in the CWS mode and displays CWS P and CWS R on the FMA’s.
The A/P maneuvers the airplane in response to control pressures applied by either pilot. The control pressure is similar to that required for manual flight. When control pressure is released, the A/P holds existing altitude.

If aileron pressure is released with 6 degrees or less bank, the A/P rolls the wings level and holds existing heading. This heading hold feature with bank less than 6 degrees is inhibited when any of the following conditions apply:

  1. below 1,500’ RA with the landing gear down
  2. after F/D VOR capture with TAS 250k or less
  3. after F/D LOC capture in the APP mode
43
Q

Pitch CWS with a CMD Engage Switch Selected

A

The pitch axis engages in CWS while the roll axis is in CMD when:

  1. a command pitch mode has not been selected or was deselected.
  2. A/P pitch has been manually overridden with control column force. The force required for override is greater than normal CWS control column force.
  3. selecting CMD while not following a large deviation in the pitch flight director command.

CWS P is annunciated on the FMA’s while this mode is engaged. Command pitch modes can then be selected.

When approaching a selected altitude in CWS P with a CMD engage switch selected, CWS P changes to ALT ACQ. When at the selected altitude, ALT HOLD engages.

If Pitch is manually overridden while in ALT HOLD at the selected altitude, ALT HOLD changes to CWS P. If control force is released within 250 feet of the selected altitude, CWSP changes to ALT ACQ, the airplane returns to the selected altitude, and ALT HOLD engages. If the elevator force is held until more than 250’ from the selected altitude, pitch remains in CWS P.

44
Q

ROLL CWS with a CMD engage switch selected

A

The roll axis engages in CWS while the pitch axis is in CMD when:

  1. a command roll mode has not been selected or was deselected.
  2. A/P roll has been manually overridden with control column force. The force required for override is greater than normal CWS control column force.
  3. flying beyond FMS end of route or into a route discontinuity.

CWS R is annunciated on the FMA’s while this mode is engaged

CWS R with a CMD engage switch illuminated can be used to capture a selected radio course while the VOR/LOC or APP mode is armed. Upon intercepting the radial or localizer, the F/D and A/P annunciations change from CWS R to VOR/LOC engaged, and the A/P tracks the selected course.
