FAM14 ETOPS Flashcards
What is reqd to be considered for an adequate airport?
- Airport availability
- Over flight and landing authorisation
- Ground assistance (I.e atc, met, air information services offices and lighting).
- Availability of services to provide at least one app (when used as an adequate airport doesn’t need a ground based navaid).
- Required fire services (4 for B737).
Notes: no need for weather assessment, inflight no to comply with rwy pavement classification.
What are the atc requirements?
For flight outside of oz territory: adequate airports must have atc or air traffic services available. Call out services within 30mins ok.
For ops within oz, ctaf must have PAL available.
What must be on tech log for etops flight?
Tech log must have etops signed off.
What are the Australian rescue and fire fighting services required?
For outside of oz min category of 4, 30min call out service is satisfactory to meet adequate requirements.
Inside oz no requirements for arffs.
What is the critical point etops (cpe)?
Generally the last equi-time point, a/c must be able to divert to either of 2 airports with reserves intact.
If there is a inter/tempo at either airport this Fuel will be carried as special holding fuel for that particular leg.
Where is the etops entry point?
The EEP is the first point on an ETOPS route where the diversion distance associated
with the threshold time from an Adequate Airport is exceeded.
I.e 60 mins
Where is the etops exit point?
The EXP is that point on the flight plan after which the aircraft will continually be within
the diversion distance associated with the threshold time from an Adequate Airport until
reaching the destination.
Where is the etops segment?
The ETOPS segment starts at the EEP and finishes at the EXP even if the flight plan
route passes within 60 minutes flight time at the OEI speed from an Adequate Airport
What is the definition of 60min diversion distance?
The 60 Minutes Diversion Distance is the distance covered in still air and ISA conditions
at the nominated OEI speed. It includes the descent from the initial cruise altitude to the
diversion cruise altitude. It is used for determining ETOPS boundaries from Adequate
Airports.
What is the 60min diversion distance?
400nm
What is the oei speed and what is it used for?
M.79/310kts
This diversion speed is used in:
• establishing the Area of Operations
• establishing the critical fuel scenario for the single-engine diversion
• establishing the net level-off altitude to safely clear any enroute obstacle by the
appropriate margin.
This speed is planned to be used in case of diversion following an engine failure.
However, the Pilot In Command has the authority to deviate from this planned speed
following assessment of the situation.
What is a nominated adequate airport?
Adequate Airport(s) are nominated as required to cover the ETOPS section of the flight.
Such an airport will satisfy weather criteria as specified in the Useable Adequate Airport
definition.
At no stage is there a requirement to notify ATC of the current NomADQs. The Pilot In
Command is only required to contact Flight Dispatch in the event that he/she does not
have a NOTAM/Weather briefing for that airport. This information may also be obtained
from ATC if appropriate.
What a usable adequate airport?
A Useable Adequate Airport is an adequate airport that is forecast to satisfy applicable
weather criteria for specified time periods as further defined for the preflight and inflight
cases. It is used to support the ETOPS segment.
The CASA name for such an airport is “ETOPS Alternate.”
Useable adequate preflight requirements?
A useable Adequate Airport for dispatch purposes is an airport confirmed:
• available (as per NOTAMs)
• satisfies the ETOPS Adequate Minima requirements for weather minima.
In additions, crosswinds forecasts should be acceptable for an engine inoperative landing the same period.
This period begins 30 minutes before the earliest Estimated Time of Arrival (ETA) at the airport and ends 30 minutes after the Latest ETA. In addition, crosswind forecasts should be acceptable for an engine inoperative landing for the same period.
What happens if preflight wx forecast is not available for nominated adequate?
Preflight, a situation may arise where the weather forecast is not available for a nominated Adequate Airport.
The flight may still depart however:
• Inflight, prior to sole reliance on an airport, a forecast showing weather at or above the Adequate Minima for the applicable period must be obtained.
• Once such a forecast has been obtained, subsequent forecasts need only be assessed against landing minima.
