What occurs when the LOC switch is pushed before localizer capture?

LOC appears in white on the PFD roll FMA as armed, while the current roll mode remains active until capture — The FCOM describes the triggering logic as “half of the switch illuminates PFD roll and pitch flight mode annunciations to indicate the mode is armed or active.” Those are the conditions that lead to LOC appears in white on the PFD roll FMA as armed, while the current roll mode remains active until capture. [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

When is FLARE mode armed and when does it become active?

Armed below 1,500 ft RA; active approximately between 60 and 40 ft RA [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

In wings-level flight with both flight directors OFF, which roll mode is engaged when the first autopilot is placed in command?

HDG HOLD — The FCOM describes the triggering logic as “These modes are: • flight level change (FLCH SPD) • heading hold (HDG HOLD) • heading select (HDG SEL).” Those are the conditions that lead to HDG HOLD. [Ref: FCOM 4.20.1]

During preflight, when can the flight director command bars first be displayed on the PFD?

When the first flight director switch is positioned ON — The FCOM describes the triggering logic as “10.10.12 D6-30151-517 Cathode Ray Tube 1 Flight Director Command Bars Indicates flight director pitch and roll steering commands.” Those are the conditions that lead to When the first flight director switch is positioned ON. [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

In VNAV, pushing the THR switch will not change the autothrottle mode.

True [Ref: FCOM 4.20.1]

With both flight director switches OFF in flight, which pitch mode is engaged when an autopilot is selected in command?

V/S — The FCOM describes the triggering logic as “4.20.1 20 System Description System Description File Highlight Introduction The automatic flight control system consists of the autopilot flight director.” Those are the conditions that lead to V/S. [Ref: FCOM 4.20.1]

What indicates a pitch or roll mode fault on the PFD?

An amber line is drawn through the affected mode annunciation [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

What FMA annunciations are normally displayed for a go-around?

THR / TOGA / TOGA [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

When engaged in a VNAV pitch mode, what sources can the FCCs use to command level-off?

MCP or FMC — The system description identifies the relevant source/actuation: “The mode control panel (MCP) and flight management computer (FMC) control the AFDS and the autothrottle system to perform climb.” That is why the correct source is MCP or FMC. [Ref: FCOM 4.20.1]

When are FLARE and ROLLOUT modes available?

During autoland operation [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

A white LNAV annunciation on the PFD indicates:

LNAV is armed [Ref: FCOM 4.20.1]

What is accomplished by lifting the autopilot disengage bar?

Autopilot engagement is enabled and the amber stripe is removed [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

During ROLLOUT mode, what do the autopilots use to track the localizer and maintain the runway centerline?

Localizer signal with rudder and nosewheel steering [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

A go-around can be accomplished with:

Single A/P, multiple A/Ps, or flight directors [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

While in FLCH, pushing the SPD switch will engage an A/T speed mode to the current airspeed or FMC speed, whichever is higher.

False [Ref: FCOM 4.20.1]

During approach, when is the go-around function of the TO/GA mode armed for the AFDS and autothrottle system?

When the flaps are out of UP, or when glideslope capture occurs — The FCOM describes the triggering logic as “The mode control panel (MCP) and flight management computer (FMC) control the AFDS and the autothrottle system to perform climb.” Those are the conditions that lead to When the flaps are out of UP, or when glideslope capture occurs. [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

Which mode is affected by the bank limit selector?

HDG SEL only [Ref: FCOM 4.10.1]

At approximately what radio altitude does the autopilot begin the landing flare?

40–60 ft RA [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

What target vertical speed is commanded by a single push of TO/GA during a go-around?

2,000 ft/min [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

What indicates that LNAV or VNAV is engaged?

LNAV/VNAV annunciation in green on the PFD [Ref: FCOM 4.20.1]

In FLCH mode, where is the commanded airspeed displayed?

In the MCP IAS/MACH window and on the PFD speed scale [Ref: FCOM 10.10.4]

After an automatic landing, how is the autothrottle normally disengaged?

When a reverse thrust lever is raised to reverse idle [Ref: FCOM 4.30.1]

After an automatic landing, how is the autopilot normally disengaged?

Using the A/P disengage switch [Ref: FCOM 4.10.1]

After an automatic landing, rollout guidance continues until:

The autopilot is disengaged [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

During an approach, when is go-around mode inhibited?

Below approximately 5 ft RA and for 2 seconds after touchdown [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

During a crosswind autoland with all engines operating, runway alignment begins at approximately:

500 ft RA [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]

During takeoff, above approximately what speed does the autothrottle enter A/T HOLD mode?

65 kt [Ref: FCOM 4.20.1]

What does A/T HOLD mode accomplish?

Disconnects the autothrottle servos so the thrust levers can be moved manually without servo resistance [Ref: FCOM Chapter 4 — Flight Instruments, Displays - Controls and Indicators]
