ETOPS - (Not part of Study Training Dept. Study Guide) Flashcards
What is considered a gross navigational error in class II airspace and what should be done to correct it?
More than 20 miles off-track or 25 nm along track.
If operating on an organized track in Class II airspace, a “gross navigation error” is an “Oceanic Track Deviation,” and requires the flight crew to immediately:
- Alter aircraft heading to intercept the track along which cleared within 200 nm, unless susequently re-cleared by ATC;
- Report the deviation and corrective action taken to ATC, using the phrase “position doubtful” if inertial references have been lost or are questionable;
- Transmit the aircraft position, flight level and “off track” status at five minute intervals on 121.5 until the track has been intercepted again, unless subsequently re-cleared by ATC;
- Turn all exterior lights “on” until the track has been intercepted again, unless subsequently re-cleared by ATC
What is SLOP and how does it work?
Strategic Lateral Offset Procedures
Provides for offsets 1 or 2 nm Right of course only. There is no ATC clearance required for this procedure and it is not necessary that ATC be advised.
Pilots may apply an offset outbound at the oceanic entry point and must return to center line at the oceanic exit point.
Exceptions:
1) Flights departing Hawaii may start SLOP once level and within 70 nm of the oceanic boundary.
2) Flights entering Hawaiian airspace may continue SLOP for 70 nm after exiting oceanic airspace or until receiving radar vectors, whichever occurs first.
What is the Area of Operation?
The Authorized geographic area for extended range operations based on the approved diversion time at the approved engine inoperative cruise speed under standard still air conditions from any point along the proposed route of flight to an adequate airport.
What is VX’s Area of Operation?
Central East Pacific (aka CEP, CEPAC) for up to 180 minutes from an adequate airport
Can the diversion time be longer than 180 minutes?
Yes. Actual diversion times are based on diversion speeds, winds, and actual conditions
What is the EEP?
ETOPS Entry Point. Marks the beginning of the ETOPS Route Segment. For Virgin America, this is the point that is 382 NM from the departure ETOPS alternate airport
What is the EXP?
ETOPS Exit Point. Marks the end of all ETOPS segments for that flight. For Virgin America, this is the point that is 382 NM from the arrival ETOPS alternate airport
What is an ETOPS Segment?
The portion of the flight that is more than one hour flying time from an adequate airport. The ETOPS Segment starts at the EEP and ends at the EXP
What are the three critical fuel planning scenarios each occurring at the Critical Point and used to determine the ETOPS critical fuel?
Engine failure (Fig. 02-5) at the most critical point followed by a descent to the one-engine inop cruise altitude using the Airbus Standard Strategy. M.78 to 300 KIAS to LRC (CI=35) to the ETOPS alternate.
Rapid decompression (Fig 02-6) at the most critical point followed by a descent to a safe altitude in compliance with the oxygen supply requirements of 121.333. Emergency Descent speed (M.82/350 KIAS) will be used to FL100 followed by cruise at MRC (CI=0)
Engine failure and rapid decompression (Fig 02-7) at the most critical point followed by a descent to a safe altitude in compliance with the oxygen supply requirements of 121.333. Emergency Descent speed (M.82/350 KIAS) will be used to FL100 followed by cruise at LRC per Airbus Standard Strategy
What is an Adequate Airport?
An FAA approved airport that meets landing limitations and is listed in Ops Spec B342 & B050
What is a Suitable Airport?
An adequate airport which, at the anticipated time of use (one hour before the earliest ETA to one hour after the latest ETA) is at or above approved WX minima.
Additionally, field condition reports must indicate that a safe landing may be accomplished with one engine and/or airframe system inoperative.
What are ETOPS Alternate Dispatch Weather Minima?
Can we use GPS-based instrument approach procedures at an ETOPS Alternate?
Only if Authorized to conduct GPS-based IAP and it meets the requirements in the table below.
If the IAP says Alternate WX Minima Not Authorized, can we still use that IAP in determining alternate airport WX minima?
NO
Must we take wind including gusts into account when determining the usability of a runway at an ETOPS alternate?
Yes.
Wind should be within the manufacturer’s maximum demonstrated crosswind.
What diversion strategy provides the best fuel burn?
The Airbus Standard Strategy (M.78 to 300 KIAS driftdown then LRC (CI=35)). The actual diversion time is increased relative to the Airbus Fixed Speed Strategy
