Atlantic crossing rules Flashcards
How can you leave your current track/route without prior clearance in NAT OTS?
Turn LEFT/RIGHT and establish a 5nm offset.
When turning to offset your track/route how many degrees do you need to turn minimum?
30deg.
What are some reason when it comes to deciding which way to turn? 4 items
Other traffic
Alternate
SLOP
terrain
What do you squak?
7700
Which frequencies can you communicate with surrounding traffic?
121.5(emrg) and 123.45 (pilot air to air)
How can you try to contact ATC?
CPDLC, HF, SATCOM, relay via other traffic in area.
When establish offset what should you do with altitude?
Establish vertical offset by 500ft. Ideally going below FL 290 will reduce chance of conflict with other traffic.
If you are above FL410 how much do you offset?
1000ft
What is the phraseology for asking for a WX offset?
“weather deviation required”
Are you required to inform ATC when no more WX deviation is required?
YES
Do you need ATC clearance?
You should always get a clearance at earliest time possible even if there is are legal ways to deviate from WX without clearance.
Do you also need to turn on ALL exterior lights for a WX deviation like you do for in flight contingencies?
YES. Allways when you leave track.
Do you need to change FL when deviating for WX?
YES if you deviate more than 5nm.
What altitude du you need to fly if you deviate more than 5nm for WX?
If you turn NORTH you descend 300ft.
If you turn SOUTH you climb 300ft.
What do you squawk with com failure?
7600
If you get communication failure prior to entry into NAT airspace are you still allowed to fly there?
Its STRONGLY recommended you do not enter NAT
Com failure in NAT. What do you do if you get com failure in NAT?
Follow cleared rute until last waypoint in oceanic clearance. After follow national rules.
What are the lost com procedures in FAA (usa) rules?
Assigned
Vectored
Expected
Filed.
What are the lost com procedures in EASA (europe) rules? IMC/IFR
IMC/IFR flight:
Radar NOT used by ATC, continue last clearance for 20min. There after continue via flight-plan.
Radar USED by ATC, continue last clearance for 7min, from: last clearance recived, squack 7600 or failure to report point. Then via flight plan
What are the lost com procedures in EASA (europe) rules? VMC
VMC: continue flight in VMC and land at nearest suitable airport.
EASA com failure. When should you start the descend/approach? OMA 12.5.10
Complete descend as late as possible and plan to start approach at: expected approach time if received OR expected arrival time.
EASA com failure. When should you land?
LESS than 30min after expected arrival time.
How is speed controlled in NAT tracks/random tracks?
MACH technic.
When do you need to keep a listening watch on HF?
If you dont have SELCAL.
From what altitude do you need a oceanic clearance within NAT?
FL60
What is the maximum difference from to entry time to estimated entry time in NAT?
3min. If you dont have ADS-C you need to ADVICE ATC.
What should a Oceanic clearance request include? 5 items
Callsign OCA entry point and ETA Requested MACH and FL. Any flightplan change Highest possible FL at entry.
How far away from OCA boundary should you request clearance?
30-90min.
When do you need to get OCA clearance prior to departure?
If less than 40min flight time from point of departure.
What does NAT HLA mean?
North Atlantic High Level airspace.
What levels are NAT HLA?
Between FL285 - FL420
What RNP approval do you need to fly across altantic?
RNP4 or RNP10
On you flight plan what does the letter R stand for?
RNP
On you flight plan what does the letter X stand for?
HLA approval.
On you flight plan what does the letter W stand for?
RVSM approval
On you flight plan what does the letter PBN/A1 stand for?
RNP10
On you flight plan what does the letter PBN/L1 stand for?
RNP4
On you flight plan what does the letter J5 stand for?
FANS 1/A
On you flight plan what does the letter D1 stand for?
Datalink
How often does a random route need to have waypoints?
Every 10degrees longitude
Are you required to have a copy of the NAT HLA Track message?
YES. There you can find the TMI (track message identification)
What is required to fly between FL350-390?
CPDLC, ADS-C and RNP4
When is it ideal to ask for oceanic clearance?
60min prior to entry (Law says 30-90min
Can you climb straight to the FL on the oceanic clearance?
NO, you need ATC clearance from domestic ATC.
What do you need to do if HF fails after you have clearance?
Fly the OCEANIC clearance. Inform VHF prior to entry.
What do you need to do if HF fails BEFORE you have clearance without domestic ATC contact?
Enter OCA at FPL requested altitude and speed. But do NOT climb while in OCA.
IF you loose CPDLC or ADS-C?
Tell ATC. They will try to keep you on your route. Worst case you will be rerouted.
What do you do if you loose 1 LRNS?
You only have 1 left. (mandatory 2)
Request clearance below or above HLA or land and get it fixed.
Is SLOP mandatory?
YES 1 or 2nm RIGHT.
When do you squawk 2000?
after 30min in OCA
How does a position report in OCA sound like?
Position, Swissair 100, RESNO at 1235, Flight Level 330, Estimating 56 North 020 West at 1310, 56 North 030 West Next.
The UTZ times were the tracks are valid what point is used as reference for the time to cross what point?
030west
What flight levels are requried to have datalink in NAT HLA?
FL290-410
What do you need to fly a blue spruce route?
Single LRNS approval
HLA approval.
Do you need autopilot in NAT HLA?
YES. to keep altitude for RVSM
What do you also need to fly the RLatSM tracks? PBCS
You need RCP 240 and RSP180.
ADS-C and CPDLC
Approvals that need to be in flight plan?
Operators are reminded that they must indicate their aircraft and flight crew capabilities (e.g. RNP, RNAV, RCP240 and RSP180 authorization, RVSM, FANS 1/A data link, ADS- B and NAT HLA approval) in the flight plan.
When should you inform ATC about WAH reports?
When you are doing position reports you should end with telling ATC when able higher.
Do you need OCA when entrering NEW YORK OCA from munction?
NO, Departure clearance from departure airport counts as route clearance.
Domestic ATC will give you speed and altitude part of clearance prior to entry.
OCA has 3 parts:
Route (atc depatrue aairport)
FL atc muncton domestic
Speed muncton domestic
Do you need OCA before entering NEW YORK OCA from gander domestic?
YES. FULL clearance by ACARS or VHF.
