Q

How does the FMC calculate a turn in LNAV

A

Evaluates 5 min prior
uses bank angle limit (based on wt and alt)

(FMC tries to use a bank that will not effect ALT or A/S)

mean

A

Q

When making changes to your route what pages do you use

A

if it involves a using an airway name ie route you have to use the RTE page

If it does not involve an airway name use the LEGS page

Q

How do you create an along track waypoint
25 nm before

25 nm after?

A

RZS/25 = 25 nm after RZS

Q

How do you build a WPT in the middle of no where

A

4 ways

place bearing/place bearing = RZS320/AVE195

place bearing/distance = ZONAL270/15

Lat/Long = N25W018 or N3538.8W12136.2 (for decimals)

PICK WPT on ND = moves a lat/long to the scratchpad

(dont forget to close out the route discontinuity)

Q

How do you create an intercept course TO a WPT

right DG 310 intercept the 090 radial TO BSR

A

310 SEL - MCP

ReEnter BSR to L1 (even if you are already going there)

INTC CRS TO appears on 6R

enter the track to the WPT not the radial

Q

How does the fuel get calculated?

2

A

Calcaulated - based on fuel burn
- used by FMC

Totalizer - sensed based on fuel level sensors

(PROG pg 2 L6/R6)

(only time FMC looks at Totalizer is before eng start)

Q

What is the ALTN Page

Alternates for diversion

25
if you want to block out airports from being alternates how do you do it an how many can you do
ALTN pg 5R - ALTN INHIBIT 2 airports
26
What do you have to remember about the DIVERT NOW promot
it dosent divert you anywhere unless you select EXEC first
27
Where can you find a drift down profile
ALTN pg 1 ENG OUT
28
How do you leave a hold
Direct to fix or select EXIT HOLD
29
What provides navigation
ADRS - Air Data Reference system IRS GPS
30
What makes up the ADRS
``` 6 air data modules 6 static ports 3 pitot ports 3 pitot probes 2 AOA sensors TAT probe 2 eng TAT probes ```
31
How does 787 determine its position
IRU + GPS + AHRU = Stable Hybrid Position
32
What makes up the IRS
Right and Left IRU + AHRU
33
What does the ON BAT between the IRS switches mean
Hot battery bus is powering the IRS
34
What will make a ILS tune automatically
Approach in the active route and <50 nm from T/D or 150 nm from landing runway or FMC in descent mode
35
How many transponders
2
36
Where can we find ANP/RNP
on PROG pg 2 L5 RNP/ACTUAL
37
What is ANP
Actual navigation performance 0.06 = 0.06 nm radius of a circle that the aircraft is in 95 % of the time
38
What is RNP
required navigation performance ``` depends on phase of flight Oceanic En-Route Terminal Approach ```
39
How do we deal with the requirement for True north in the FMC Polar Region
We dont, all done automatically If Heading Ref is NORM
40
What is used for ATC DATALINK
CPDLC - Controller to Pilot DataLink comunications
41
What are the 3 VNAV Modes
VNAV SPD -commanding pitch to maintain airspeed pink bug and pink speed at top of tape VNAV PTH - commanding pitch to maintain vertical path VNAV ALT - Temparary ALT hold Mode - Due to MCP alt it holds until it can climb to the planned VNAV PTH
42
Just after rotation what speed is targeted by the the FMC
V2 + 15 kts or Air Speed at rotation + 15 kts whichever is greater
43
When does LNAV and VNAV engage during T/O
LNAV - 50 ft VNAV - 400 ft
44
Where does the VNAV profile created
in the VNAV pages on the CDU THR REDUCTION - 1,000 ft ACCEL HT - 3,000 FT
45
When does the VNAV climb Phase start
after T/O when the FMC commands climb thrust - THR REDUCTION
46
What are the VNAV Altitudes used for thrust management based on
AGL
47
What is the VNAV limit to airspeed with respect to flaps
max of 5 kts below red line flap placard speed
48
Where does the ECON SPD come from
COST INDEX entered at the preflight
49
When does FMC switch to Cruise phase
T/C top of climb
50
What is step size
point when wt is reduced and a higher alt is safe to save fuel. 2,000 ft ICAO 4,000
51
How do you create a step climb for VNAV
LEGS page Enter alt with and s as a waypt /FL260S
52
How do you enter a specific speed at a Waypoint
LEGS page Enter speed in Mach .820/FL260
53
How can you set up an early descent > 50 nm
Set MCP Altitude VNAV descent page (pg 3) DES NOW (1250 fpm and used Cruise page parameters)
54
How can you set up an early descent < 50 nm
Set MCP Altitude | 1250 fpm and DESC page perameters
55
What is TAI/ON ALT
Thermal Anti-ice ON Altitude Engine anti ice during descent Calculates higher RPM to maintain Eng anti ice
56
What is OFFPATH DES
descending when not on LNAV VNAV DESC page creates a circle to the WYPT to see if you can make it in time Clean and DRAG (speed brks) circle (can be modified on the DESC page
57
When does VNAV Descent change to VNAV Approach
Flap moved out of UP or First waypt on the active approach
58
If descending below the approach path how does the VNAV transition
When flaps 1 are selected the Aircraft levels off until it intercepts the path
59
For IAN approaches what are the indications
``` G/P = G/S FAC = LOC ```
60
How can you get speed/flap guidance on app
make sure MCP speed window is blank
61
Where can you get nav information if you had a loss of all three FMC's or loss of all displays
Alternate Navigation on TCP press NAV button on TCP ALT NAV pg 1 ALT NAV RADIO pg 2 (turn control on 1R) (CAPT TCP works on STBY pwr) (uses left INR) (ILS displays on the ISFD and capt PFD)
