NAT REGION Flashcards
What is the new (Oct 17 2018) distance for etops alternates at 330 kts
60 min
120 min
180 min
60 min - 458 nm
120 min - 878 nm
180 min - 1317 nm
(We are now using one distance for -8 and -9, and it uses a statistical average using average of
reference weights for flights when operating in the planned ETOPS area was used instead of t/o weight minus 1 hr)
What is the Critical point
most critical point from a fuel perspective to:
- go to ALT under the most adverse conditions
- descend to 1,500 ft at Destination 15 min HOLD and APPROACH
What do we use as crosswind for altn
- 8 80% of 35kts = 28 kts
- 9 80% of 33kts = 26 kts
When you have 2 ETOPS ALTN what do you require?
ETP - Equal Time Points
3 ETOPS = 2 ETP
For Critical point what is usually the most limiting
DX - One eng Decompression
DC - decompression all eng
1X - one eng fail
DX - One Eng Decompression is usually the most limiting
When using single ETOPS what is usually the Critical Point
Entry point or the Exit point
What is the PTOB
Fuel to CP and have an emergency and get to alt
basically the last chance before entering etops
what is PFOB
protected fuel on board
fuel that cant be used
what is the IFV
inflight verification of servicability procedure before entering ETOPS
How do we plot position after wpt passage
QRHN - pg 64
POS REF - lat/Long
ipad tap point close, edit new point
1212Z name
Lat/Long from FMS
use Protractor on RT side to determine dist
(you can be rampped and asked for these points)
What is the beignin area
Caribbean
75 nm
Reason is lots of airports and really good wx
What is an adequate airport?
Provides a level of service
Can be used as an alternated but is not designated
Jepp/company Manuals/AC TAB ECoverage
Destination (D)
Alternate (A) - suitable passenger handling
Escape chart airports (EC)
Where is the ETOPS operational checklist
QRHN
nothing on EICAS
What do you do if you get a RECLEARENCE
QRHN
How can you set up notifications for 2 Hr fuel checks
Fix page
COMM - Reminders
What is SLOP
Strategic Lateral Offset Procedure (SLOP)
method to increase safety margins
OFST R2
start wypt
end wypt
EXEC
Sqk 2000 30 min after entry
1 or 2 nm RIGHT (70% slop 1, 20% no slop, 10% slop 2)
reduces exposure to wake turb
>FL290
Offset shall not be applied prior to crossing oceanic entry waypoint, and shall be removed prior to the oceanic exit waypoint
Position reports are based on the centerline waypoint and not the offset position
What has to be done prior to ETOP’s entry?
QRHN
- Request Oceanic clearance (NAT)
- Check clearance with FMS
- Check ETOPS Altn WX
- ETOPS Altn on appropriate ALTN pg
- HF assignment/SELCAL Check
- Ensure cleared MACH in LEGS
- CPDLC/ADS
- ETOPS Systems Operational
create fix for 30 min after oceanic entry point for sqk2000
What has to be done at Oceanic entry
PF
- SLOP after entry (0, 1 or 2 nm Right
where appropriate)
PM
• VHF L = 121.5 R = 123.45
• SQ 2000 30 min, after entry (NAT)
2-3 min to User defined WPT
PF - confirms FMS POS
WPT
Track and dist to next
and next after that
PM- ALT, Altitude, MACH, GPS
Eng GAGES
Time, temp, wind, fuel, Alternates
WPT Passage
PF
Check Altimeters, Altitude, Mach
• Confirm method of FMS update
PM
• Record time, alt, temp, wind & fuel
• Crew note location of potential ETOPS alternates
After WPT
PF
Confirm next waypoint, Track & Distance on ND
(not fmc)
PM
10-15 min or 2-3 deg after WPT, plot position
How do we plot position
2-3 min after waypoint
PROG POS REF Select current lat/long to scratch pax JeppFD-Pro map and create wpt with Lat/Long Use protractor to measure the slop
Oceanic exit
PF
Remove SLOP offset prior to exit (if
used)
PM
• CPDLC/ADS as required
• Check MACH number if it differs from Oceanic
• Contact Domestic ATC & squawk as assigned
• Heading Reference—NORM (as required).
• Confirm method of FMC updating
What is a TMI number for NAT tracks?
Track message identifier
Number to ensure you are using the proper nat track for that day
69 is the 69 day of the year
What separation is given for RNP 4 and RNAV 10for NAT tracks?
60nm
30nm
What is a random route
Any route that does not follow a NAT track
Even above or below
What does winds of 150 at 5 m/s mean
150 10 kts
What are the procedure for answering SELCAL
Chime
EICAS - .SELCAL
Call in mic
“Air Canada answering SELCAL”
(Every time you get a new FIR you test SELCAL
“Request SELCAL check”)
What is ADS -C
Automatic dependent surveillance contract
-a way for ATC to pull data about the aircrafts position and performance
(Requires no pilot input)
Also called FANS 1/A
What is ADS-B
Automatic dependent surveillance broadcast
Transponder function (VHF)
Broadcasts in background blindly position and performance information
Why do we have SELCAL
To back up CPDLC
