A

350nm ring is alternate for TO alternate

418nm ring is for suitable alternates enroute for non EDTO flights

86
Q

When can you use the “Commit to destination” philosophy?

A

When flight time is greater than 2hours and you are within 2 hours of destination.

Required to have a TAF 3 for domestic ops valid until 30 minutes post landing
Can use METAR/SPECI/TAF for international ops (as these include 2hr trends)

Captain just deem the wx conditions suitable to be able to land, even though may be below listed minima but still allows any approach of some kind.

Low vis approaches can’t be planned

87
Q

What is a typical engine oil burn per hour ?

A

0.4-0.6 per hour

(Be aware of this on long sectors, make sure enough oil for the return eg: 12 flying hours = 5, so you’d want to have 17 before first sector to ensure min 12 for return)

88
Q

A

SID
SQUAWK
BAY

(FOR YSSY OPS, ALSO RUNWAY AND TRANSITION)

89
Q

What is a rough figure for LDR?

MAX WEIGHT, FLAPS 30, VREF+5

A

2000m LDR - this includes 455m air distance

*each blue airport on ND represents a runway 1526m available and is suitable for landing if needed eg: on fire)

90
Q

Latest point of touchdown example - (150m to 900m or first third of the runway whichever is less)

LDR YPPH RWY 24 - 2070m

LDA - 2163m

For the above where would you nominate latest point of touchdown ?

A

5 x 150m markers RWY24 = 750m total zone

LDA - 2163 / 3 = 721 m (earliest point = 150m markers, latest point = 721m)

So at Perth you would use the end of the 4th markers as a defined latest point of touchdown. Which equals - 4 x 150 = 600m

91
Q

How would you confirm refuelling is complete ?

A
  1. required fuel shown on gauges
  2. If DC selector is on BATT, during fuel panel operation this takes power and would show around 28V, once refuelling is complete and fuel panel closed the voltage goes to 30-31V as the APU now recharges the respective battery.

101
Q

Explain 737 Max Cross FCC system -

A

On NG FCC flip flops between each flight.

Due MCAS on the max, cross FCC was introduced so the standby FCC always does a reliability check to the operating FCC for trim commands.
If the reasonableness is out of tolerance the FCC will be cut off from making inputs to the STS

On landing, STAB OUT OF TRIM light will illuminate to tell you one FCC was locked out

102

106
Q

-700 MTOW & MLW

A

70,080

58,604

107
Q

Why is an AFT CG beneficial?

A

Increases the lift available at a given AOA due to the reduced nose up trim required.

Improving aircraft climb perf
Allows a reduced vR & v2 therefore reducing field length required for TO

108
Q

When is a rolling start recommend?

A

When XWIND exceeds 20kts or TW exceeds 10kts

109
Q

When using ATM the takeoff speeds are still calculated as a full rates thrust take off.

A

Therefore you can apply max thrust anytime and be covered in regards to VMCG/VMCA

110
Q

If V speeds are lost and no pilot recalls the Vr speed. When should the crew rotate the aeroplane ?

A

5 to 10kts prior to v2 speed

111
Q

Once above white bug OEI you have full bank 30 degrees.
When below the white bug limit bank to 15 degrees.
Although the FD may command more

A

As above

112
Q

What does the green light on MCP mode mean ?

A

The mode can be deselected

113
Q

Can you conduct an auto land off a GLS?

A

Yes.

Check company 10-7 charts for approved runways. Some runways are approved with no ILS. So can do it from GLS

114
Q

OPT QNH calculation - when do you need to recalculate ?

A

When QNH drops more then 1 hpa

Can have unlimited changes in an increase scenario

115
Q

When must engine anti-ice be on during climb, cruise and descent ?

A

Anti ice must be on during climb and cruise unless SAT is below -40 degrees.

On descent it must be on in all icing conditions even if it’s below -40 degrees. Until TAT +10 or exiting icing conditions

116
Q

119
Q

REOPENING DOORS ON GROUND

NOT ARMED
ARMED

A

Not armed - CM will get approval from flight crew. Return to bay and organise appropriate GSE in place before reopen

If opened due to obstruction assessment made if any damage and if engineers needed to assess.
CM will also get clearance from flight crew to close the door

ARMED -
CM will gain approval from flight crew
Return to bay. GSE in place
Captain will switch off seatbelt sign but CM PA to advise everyone to remain seated.
FO will make disarm PA CC will ensure all doors disarmed
Approval to open and approval required to close.

A

Descend now - maintain 1000fpm until it captures an idle descent path

SPD - Will prioritise speed over path. Good for scenarios where overspeed may be likely. But no path protection for altitude requirements

PTH - prioritise path however no overspeed protection. It will let it run into an overspeed.

Q

Gross error n1 check
C9 manual

A

0.4% difference in n1 is acceptable due to OAT difference in actual OAT and OPT entry

125
Q

Remember to cancel CLB 1/2 once get unrestricted climb.

A
126
Q

Use max rate / angle to get out of weather and bumps. Or use SPD INT to reduce speed

A

As above

127
Q

Take note of CI value and wind in FMC set up.
High CI will give a high climb and cruise Mach which may lead to an over speed or very close.

Dont be afraid of reducing it in the preflight stage as a mitigater to prevent an overspeed

A

Can always make it faster again once conditions are suitable

128
Q

Immediate return things need.

Ref QRH for order

A

Bugs - Ref15
CRS
ILS/GLS FWD
Flap Inhibit
TA ONLY

129
Q

Holding - how long is half a turn at high altitude ?

A

2.5 minutes

130
Q

If given a height to be at for the hold how can you achieve this using VNAV and making sure you arrive at that altitude a little early ?

A

Grab WPT name - XXX /-10 (creating WPT 10nm prior)
Then put your altitude limit at that WPT.

ONCE YOU GET CLOSER TO THE ALT AND WPT TAKE MANUAL CONTROL OF ROD FOR TCAS ETC

131
Q

What actions need to be done when completed the hold ?

A

EXIT HOLD
ONCE ESTABLISHED INBOUND - DTO
CHANGE CRZ ALT
CHANGE SPD TO CURRENT SPEED AND HAVE 250kts READY TO EXECUTE AT COMPLETION

132
Q

When at min speed and then you get descent to allow for eg: vectors -

Amend CRZ ALT and make sure amend speed to current min speed MACH and descent MACH to current min

A

As above

133
Q

ILS
GLS when good use distance ?

A

ILS - 25nm
GLS - 23nm

Yes LNAV until cleared approach preferred

134
Q

Note discos that take you to the aerodrome then calculate track miles back to the start off approach.

This will leave you way high
Use 20nm ring. 5000ft there and also a point to start bugging back
