WX FORECAST AVAIL
SERVICES AND FACILTIES IE LGTS AVAILABLE
LDA MUST BE AT LEAST DRY LDG DIST AT EXPECTED LW
AT LEAST ONE INSTRU APP AVAIL

ADDITIONALLY AIRCRAFT MUST BE ABLE TO LAND AND PARK WITHOUT THE LIKELIHOOD OF DAMAGE TO AIRCRAFT OR THE AIRPORT BEING RENDERED UNUSABLE FOR OTHER OPS INCLUDING OAVEMENT RESTR

WHEN USED TO SUPPORT NON EDTO FLTS WX FORECAST AT ADEQ APT DOES NOT NEED TO BE CONSIDERED

18
Q

WHEN CAN EDTO LIMITS BE EXCEEDED

A

FOR SAFETY REASONS

IE WX AVOIDANCE

IN PREFLT PHASE COMPLIANCE ENSURED BY CONSTELLATION

19
Q

NON EDTO PLANNING

A

FLT CONSIDERED NON EDTO IF IT REMAINS WITHIN EDTO THRESHOLD DISTANCE OF AN ADEQ APT AT ALL TIMES

20
Q

TLS CHECKS

WHICH AIRPORTS

A

ONLY CAT A B OR C
NOT EMERG APTS

787
MOST LIMITING TLS OTHER THAN CARGO FIRE SUPP MINUS 15 MINS IE 330 MINS CONVERTED TO DIST AT OEI CRUISE SPEED

21
Q

ATS REQMTS

A

AIR TRAFFIC SERVICES

FOR AN APT OUTSIDE AUSTRALIA TO BE USED AS AN EDTO ALTN NEED ATS WITH NOT MORE THAN 30 MINS NOTICE

IN AUST NO REQMT

22
Q

RFFS

A

RESCUE FIRE FIGHTING SERVICE

OUTSIDE AUST NEED CAT 4 RFFS WITH NOT MORE THAN 30 MINS NOTICE

IN AUST NO REQMT

23
Q

AIRCRAFT SYSTEMS

MEL DDG

A

MEL DDG MAY AFFECT MAX DIVERSION TIME

24
Q

CRITICAL FUEL SCENARIO

A

BASED ON FAILURE OCCURRING AT CPE

OEI 2 ENG AIRCRAFT ONLY
DEPRESSURISED AND
OEI AND DEPRESSURISED

25
Q

DIVERSION PROFILE

A

DESCENT TO PLANNED DIVERSION ALT
CRUISE AFM APPROVED SPEEDS
DESCENT TO 1500’ ABOVE EDTO ALTN
APPROACH AND LANDING

26
Q

CPE

EXPANDED

A

CONSTELLATION APPLIES FORECAST WIND AND TEMP TO CPE CALC BUT ADJUSTS HWC TWC BY 5%

OFP SHOWS CPE INFO:
TWO EDTO ALTNS CPE BASED ON
LAT AND LONG CPE
EET TO CPE
LOCATION IN REF TO NEXT WAYPT
EET AND ETA FOR EACH EDTO ALTN
PLANNED FUEL AVAIL FOR CPE CALC
MIN FUEL REQD

30 MIN FRF NOT APPLICABLE TO CPE CALC

INTER/ TEMPO AT EDTO ALTN PLANNED AS REQUIRED ADDITIONAL FUEL

27
Q

EDTO ALTN WX ASSESSMENT

A

FORECAST CEILING AND VIS
FORECAST XWC INCL GUSTS FOR LANDING RWY MUST BE LESS THAN OEI LDG
PROB LESS THAN 40% DISREGARDED
INTER AND TEMPO TAKEN INTO ACCOUNT

CAN DEPART WITHOUT FORECAST BE MUST CHECK PRIOR EEP FOR THAT ALTN APT

28
Q

OEI CRUISE SPEED EDTO

A

FLT PLANNING SYS USES APPROVED RANGE OF SPEEDS TO:

REDUCE REQUIRED ADDITIONAL FUEL MAXIMISING PAYLOAD UPLIFT OR
INCREASE EDTO AREA OF OPS

29
Q

OFP

A

OFP FOR EDTO FLIGHT HAS ADDITIONAL INFO:

CPE
TLS STATEMENTS
EDTO DATA SECTION

30
Q

TECH LOG REMQTS

A

CRS NEED Y IN EDTO BOX

31
Q

EDTO INFLT FUEL REQMTS

A

AS PER NORMAL INFLT REQMTS

EDTO PLANNING MAINLY PREFLT ACTIVITY

NO REQMT TO DIVERT IF FUEL ONBOARD IS BELOW PREDICTED FUEL AT CPE AS DOING SO MAY EXPOSE AIRCRAFT TO GREATER RISK

32
Q

EEP

INFLT CHECKS

A

2 WAY COMMS VHF HF CPDLC WITH ATC
2 WAY COMMS ACARS HF SATCOM WITH FLT DISPATCH
INFLT FUEL REQMTS MET
NO SERVICEABILITY ISSUES IE EDTO SIGNIFICANT SYS ISSUES
NOTAMS AND MSGS FROM FLT DISPATCH HAVE BEEN REVIEWED
EDTO ALTN USEABILITY AND WEATHER VIA UPDATED TAF TTF ACTUAL
INFLT ASSESS AGAINST LANDING MINIMA

33
Q

EDTO ALTN UNAVAILABLE

A

ONCE FLT HAS ENTERED EDTO SEGMENT AND AN EDTO ALTN BECOMES AVAILABLE EG DUE TO AIRCRAFT SYS FAILURE OR WEATHER THE FLT MAY CONTINUE AT PIC DISCRETION

34
Q

EDTO SIGNIFICANT SYSTEM

A

BOEING
PLAN TO LAND AT NEAREST AVAIL APT

SHOWS AT A MINIMUM A FAILURE OF EDTO SIGNIFICANT SYS

IF EDTO FLT MUST PLAN TO LAND CAT A B OR C WITHIN EDTO MAX DIVERSION TIME ON OFP

A SIGNIFICANT SYS WOULD NORMALLY PRECLUDE ENTRY INTO EDTO SEGMENT. PIC MAY ELECT TO ENTER EDTO SEGMENT IN ORDER TO PROCEED TO AN APT IF ASSESSED AS LOWER RISK THAN DIVERTING TO CLOSER APT

FOR FAILURE NO NEED TO DIVERT TO CAT C. CAN PROCEED CAT A OR B ABOVE LANDING MINIMA

CAT C APT MAY NEED EMERG DECLARATION

35
Q

OEI CRUISE SPEED

EDTO

INFLT

A

OEI CRUISED SPEED ON OFP FOR PLANNING PHASE AT CPE

ACTUAL SPEED FLOWN AT PIC DISCRETION DEPENDING ON AIRCRAFT FUEL STATE AND LOCATION WHEN FAIKURE OCCURS

36
Q

DIVERSION STRATEGIES

INFLT

A

TIME STRATEGY
FOR MINIMUM TIME IE CARGO FIRE CAN USE VMO MMO

FUEL STRATEGY
MAXIMUM ENDURANCE CAN USE OEI LRC TO MINIMISE FUEL BURN

OBSTACLE STRATEGY
MAX L/D BEST OEI ALTITUDE OERFORMANCE UNTIL OBSTACLE CLEARED

FLT CREW NOT LIMITED BY THESE STRATEGIES

37
Q

COMPANY COMMS

INFLT

A

ATTEMPT TO ESTABLISH COMMS AS SOON AS OPERATIONALLY POSSIBLE

ACARS HF ATC

38
Q

FLIGHT WATCH

IN FLT

A

APT WX LESS THAN LANDING MINIMA FLT CREW WILL BE NOTIFIED

39
Q

EXP

IN FLT

A

ONCE EDTO EXIT POINT EXP IS PASSED FLT BECOMES NON EDTO

40
Q

EDTO MAX DIVERSION TIME

A

MUST NOT EXCEED TLS MINUS 15 MINS

IR CARGO FIRE SUPPRESSION 300 MINS SO MAX 285 MINS
