ETOPs + MNPs Flashcards
Master document
Operational flight plan - must be available in flight
Position plotting
Check where you are against the operational flight plan
Plot the a/c posn at certain times
When should you check your posn
At each waypoint and 10mins after
SLOP
Strategic lateral offset procedures
Random selection by the crew of 1 of 3 tracks
Centreline
1nm right
2nm right
Offsets to the left can’t be made
Altimeter cross checks should be carried out
When passing waypoints or at intervals not exceeding 60mins - whichever is the earlier
On reaching a new FL
Must agree within +/- 200
In MNPs airspace must make a report
Whenever a vertical deviation of 300ft or more occurs
Must report when leaving/reaching a new FL
Flying above MNPs airspace FL
Above = FL420
Below = FL285 (280)
If the system fails while on an MNPs route - less than 2 systems you climb and descend
500ft to get a different level within RVSM
Oceanic ATC clearances
40mins before entry
20mins before entry for Reykjavik area - entering from Scottish/Stavanger areas
A/d close to OCA - may need one before dep
3 elements to an oceanic clearance
Route - Sep by 60nm - 1 degree - reduced lateral sep = 30nm and can go to 25nm on some days
Mach no - 10min sep
FL - 1,000ft sep
HF comms
Conducted on single sideband HF freq in 6 ground radio stations
Does not require much power
Ground stations have no executive ATC authority
Lower HF at night - less than 7 MHz - higher during the day - more than 8
A/c normally get a primary and secondary freq
SELCAL and what does it do
Selective calling
A/c are given a call code - 2 letters A to S excl I,N and O - code is placarded
Obviates the need for the use of HF radio
Need to do a SELCAL test before entry
Satcom communication diff between routine and emerg in where they go
Routine - made to ground stations.
Emerg - direct to OCA centre
When out of range of VHF stations what can be used for air to air comms
- 45
121. 5 should be monitored by all a/c operating in the NAT region
Posn reports - NATS routes
Should be made at sig points or when required by ATC
Contains lat and long except when flying over named reporting points - all times should be expressed in 4 digit UTC
