ORCA Brief and Sim Flashcards
What does ORCA stand for?
Oceanic and Remote Continental Airspace
What does ORCA comprise?
ORCA comprises Class II Nav procedures and ETOPS procedures
What is Class I navigation
Route lies within the operational service volume of the facilities defining the airway OR be flown using an RNAV system, provided the aircraft’s position can be “reliably fixed” at least once each hour using airway navigation facilities.
What is Class II navigation
Anything not defined as Class I, typically involves flights that will exceed 725 nm between ground-based navaids.
What is the definition of Overwater
> 50 nm from nearest shoreline (inform purser)
What is ETOPS?
- Greater than 60 minutes Single Engine cruise from an adequate airport.
What are typical ETOPS ranges for the 737?
One hour single engine distance:
* 700: 425 nm
* 800: 430 nm
* 900: 424 nm
What is the MFP?
Master Flight Plan. During ORCA one copy of the OFP is designated as master. The MFP serves as the reference for changes to the flight routing, tracking ATA/ETA timing and fuel tracking.
What is an MFL?
Master Flight Log. A log available via ACARS and designed to be used in lieu of a paper MFP.
What is the difference between an adequate and suitable airport?
What does each apply to?
Adequate: The runway must be sufficient to accommodate the aircraft
Suitable: Considers runway, facilities, approaches, geo-political factors, etc.
Adequate applies to ETOPS entry/exit and Suitable applies to Critical Point
What is the Critical Point?
Point at which the aircraft is at equal time (not distance … wind must be considered) between the ETOPS alternate airports at 10,000’
When do we show up for a long range flight?
Basic Flight: 60 minutes (Alaska, Hawaii, Cent Amer, etc.)
Global Flight: 90 minutes (Azores for CLE pilots)
When do you have to contact dispatch for an ORCA flight?
Must contact dispatcher for flights of 6 hours or longer. Encouraged for shorter flights.
What do you have to do at the step:
Master Flight Log/Plan … Designate
Write “Master” on the top right corner of the flight plan.
What do you have to do at the step:
ATC filing … Review
Go on page 2 of the flight plan to verify the route.
For ORCA, what must you put into the FMC for reserve fuel?
Add up the times of lines 2, 3 & 4 of the fuel plan.
2) FAR
3) ACF90
4) Alternate airport
Do you have to have a paper copy of the OFP?
Yes. Ap printed copy of the OFP must be carried on the flight and must be marked as the “Master” flight plan.
What type of airport is required for dispatch has an ETOPS alternate?
Adequate
Prior to ETOPS entry, if an ETOPS alternate becomes unusable, what must be accomplished to enter ETOPS airspace?
The CA and Dispatcher must agree on a plan to continue the flight. The plan must include naming a different ETOPS alternate or dispatch under a level of ETOPS supported by available alternates.
After ETOPS entry, if an ETOPS alternate becomes unusable, must the crew revers course and exit ETOPS airspace?
No. The flight is not require to turn back. The CA, in coordination with the Dispatcher, will evaluate the situation and make a decision as to the safest course of action.
Is an alternate always required for dispatch under Flag rules and OpSpecs?
No. the 6 hour rule destinations approved with no alternate are exceptions. See FOM Flag Alternate Requirements
What is the reserve fuel required for Flag operations?
Either 30 minutes of fuel based on landing weight at 1500 AFE or 2 hours of fuel based on the method of dispatch used.
What is the company planed REMF fuel for Domestic flights? Flag flights?
Domestic: 60 minutes
Flag: No less than 75 minutes
Is the taxi fuel computation based on single or dual engine taxi?
Taxi out burn rate is computed based on the all-engine fuel burn.
Where should the ETOPS Critical Point be placed in the FMC?
Placed after the last waypoint on the LEGS page and generating a discontinuity between the CP and last waypoint.
If you have a successful HF SELCAL check, do the HF radios have to be monitored during the flight?
No. Not with a valid SELCAL check.
What 737 types might need a Flaps 5 go-around?
All except the -700 and straight -900
When might you need a Flaps 5 go around?
- When dispatch planned and noted ALTN GO-AROUND FLAPS 5 CONFIG in the dispatcher remarks, OR
- When returning to land at a departure airport with a pressure altitude of 5000 MSL or higher.
