When do Flight Director Steering Bars appear on the PFD?
- When the Flight Director Switch is turned
on. - When the Flight Director Bar is turned off
and a Go Around Switch is pushed and
the aircraft speed is above 80 kts with
flaps not retracted.
How can Flight Director Display Bars be turned off if the flight Director Switch is already turned off?
Turn the Flight Director Switch back on, then off again.
“LAND 3” means…?
Three auto pilot is engaged and operating normally for an automatic landing. (FAIL OPERATIONAL)
“LAND 2” “NO LAND 3” means…?
LAND 2: Redundancy reduced, in some cases only two auto pilots available. (FAIL PASSIVE)
NO LAND 3: indicates a fault condition exists which results in a LAND 2 condition.
“NO AUTOLAND” Means…?

What are the Autothrottle modes (A/T) on the FMA?
A/T Modes on the FMA:
- SPD

- FLCH
- GA
What does “SPD” mean in the Autothrottle portion of the FMA?
Auto throttle controlling thrust to maintain speed selected in IAS/MACH or, if VNAV engaged, the speed as programmed by the FMC.
What does “IDLE” mean in the autothrottle portion of the FMA?
Auto throttle is reducing or has reduced thrust to idle. It may engage in a VNAV descent. It will, after FLARE is engaged.
What does “THR HOLD” mean in the auto throttle portion of the FMA?
Thrust levers remain in existing position or where manually placed
What does “N1” mean In the auto throttle portion of the FMA?
Autothrottle controlling to the selected N1 reference thrust
What does “FLCH” mean In the autothrottle portion of the FMA?
Auto throttle controlling to a maximum of the selected mode reference thrust during climb, and to a minimum thrust during desert.
What does “GA” mean In the auto throttle portion of the FMA?
Auto throttle control into a maximum reference thrust to maintain a climb rate of at least 2000 FOM. If both flight directors and the auto pilot are off, auto throttle controls to go around reference thrust subject to flap and VMO limit speeds.
What are the ROLL modes on the FMA?
ROLL modes on the FMA:
- LNAV
- HDG SEL
- HDG HOLD
- LOC
- B/CRS
- TO
- GA
- ROLLOUT
If selected, when will LNAV immediately activate?
When LNAV is selected within 2.5 miles of the active leg.
When will “HDG” display in the ROLL portion of the FMA?
When the Heading button on the MCP is pressed.
When will “HDG HOLD” display on the ROLL portion of the FMA?
When in HDG mode and the heading displayed in the heading window of the MCP is captured.
When will “LOC” display in white on the ROLL portion of the FMA?
When LOC is selected on the MCP but the localizer course is not captured.
When will “LOC” display in green on the ROLL portion of the FMA?
When LOC is selected on the MCP, the localizer is within range and within 120 degrees of the localizer course.
(T/F): When flying a Back Course Localizer, once captured, the AFDS will fly the inbound course of the BC Localizer freq.
True
On the ground, when will “TO” display on the ROLL or PITCH portion of the FMA?
When either Flight Director Switch is turned ON When both are turned off.
When will “LNAV” display in green on the ROLL portion of the FMA?
When the aircraft is in position to turn onto the active route leg.
When will “LNAV” display in white on the ROLL portion of the FMA?
When LNAV is selected on the MCP.
When does takeoff roll and pitch guidance become active during takeoff?
Immediately upon lift off.
In flight, when does GA arm?
When not in CLIMB mode and with flaps out of “UP” or glide slope capture.
What is the display on the FMA for GA armed in flight?
There is no annunciation on the FMA for GA armed in flight.
Although… the thrust reference limit on N1 changes to the go-around limit and a green “GA” will appear above the N1 gauge.
On a GA, what does the Flight Director initially provide you for roll guidance?
The AFDS guides you on the track captured upon GA activation.
When is “ROLLOUT” armed and activated?
Armed at 1500’ radio altitude.
Activated at 5’ radio altitude.
What are the PITCH modes on thenFMA?
PITCH modes on the FMA:
- TO
- GA
- VNAV SPD
- VNAV PTH
- VNAV ALT
- V/S
- ALT CAP
- ALT HOLD
- G/S
- FLARE
On takeoff roll, the Flight Director commands how much pitch?
Eight degrees nose up.
What does the AFDS command for PITCH?after takeoff?
The AFDS commands a pitch attitude to maintain a speed greater than V2 plus 15 or lift off speed plus 15.
On initial takeoff, once airborne, how will the AFDS adjust if current airspeed remains above the target airspeed for five seconds?
Target airspeed resets to current airspeed, to a maximum of V2 plus 25 knots.
What does the AFDS set for target airspeed on a go-around?
The airspeed set in the IAS/MACH window or current airspeed, whichever is higher.
On ango-around, how will the AFDS adjust if current airspeed remains above the target airspeed for five seconds?
Target airspeed resets to current airspeed to a maximum of the IAS/MACH window speed plus 25 knots.
How does the AFDS adjust if airspeed at initiation of go-around is already > IAS/MACH window plus 25 knots?
Than current speed is maintained.
What is displayed in the PITCH section of the FMA when VNAV is armed on the MCP?
A white “VNAV.”
What is displayed on the PITCH section of the FMA when VNAV is active?
A green “VNAV.”
When in “VNAV SPD” mode, what speed will the AFDS target?
Either the MCP IAS/MACH window speed or the speed in the FMC CDU CLIMB or DESCENT page.
During Speed Intervention, how can you quickly set a target speed for the AFDS to fly?
Press the IAS/MACH button and set a speed in the IAS/ MACH window of the MCP.
How does the AFDS maintain VNAV Path?
With pitch commands.
How does the AFDS adjust for unanticipated winds while on PATH?
Thrust adjustments.
Pressing the Vertical Speed “V/S” tile on the MCP results in what?
The current vertical speed displays in the V/S window a SPD the current IAS displays in the IAS/MACH window.
How can you open just the IAS/MACH window?
Press the SPD tile on the MCP.
When is FLARE armed (in white) on the Pitch section of the FMA?
Armed at 1500’ radio altitude.
During AUTOLAND, when does the FLARE mode activate (turn green)?
Activates at 45’ radio altitude.
(T/F): When in VNAV, the AFDS
Autothrottle modes and target thrust settings.
What is “ALT CAP” on the Pitch section of the FMA
When a MCP altitude is captured from a FLTCH, V/S, or VNAV climb or descent to a MCP altitude.
What causes “VNAV ALT” to display on the FMA Pitch page and the plane to level off?
When you have a conflict between the Nav profile and the MCP altitude.
How does the AFDS maintain VNAV Path?
Using pitch commands to maintain path, with optional thrust settings to maintain speed for winds not entered into the FMS.
What displays on the CDU scratch pad if you approach top of descent point without resetting to a lower altitude in the MCP altitude window?
“RESET MCP ALT”
What does “TMSP” stand for?
TMSP = Thrust Mode Select Panel
What are the Thrust Modes available on the TMSP?
- TO
- GA
- CLB
- CON
- CRZ
- TO1
- TO2
- Derated TOs
How can you turn off the Autothrottle?
- Place the Autothrottle Arm switch to
“OFF.” - Pressing either Autothrottle Disconnect
Switch.
What must be pressed on the MCP to fly a BC Localizer approach?
Press two tiles:
- LOC
- B/CRS
When does FLARE arm?
At 1500’ radio altitude or when either LAND 3 or LAND 2 annunciates.
