Minimum vertical separation within HLA airspace is 1000 feet up to and including FL410, and 2000 feet above that.
Supersonic flights require 4,000 feet vertical separation from all other traffic if no other form of separation exists. This applies at any level for aircraft at supersonic speeds
Minimum lateral separation is 19nm
NATs are normally defined so that they do not change latitude by more than 2 degrees for each 10 degrees longitude difference thereby ensuring more than sufficient separation.
Lateral = aircraft flying parallel to eachother
Minimum longitudinal separation for aircraft is 14nm.
Longitudinal = aircraft flying behind eachother
Aircraft with different speeds on the same track/FL will gradually get closer or further apart. It is imperative to monitor this change of spacing closely for loss of separation. Aircrafts are requested to maintain the filed/requested mach speed.
SELCAL, or Selective Calling, is a signalling system used in conjunction with High Frequency (HF) radio communications. It is used to alert pilots communicating with ATC of an incoming radio message on HF as pilots are not required to monitor the HF frequency due to the background noise.
Following entry is required in th FP remark section (Field 18.) for SELCAL to be used:
Example:
ATC should add a SELCAL to the remark section (Field 18.) if it's missing. Codes can be generated here.
The pilot will hear the actual SELCAL sound notification in the pilot client (Altitude) as well as a text notification:
👉 Aircraft need to stay on frequency in order to receive a SELCAL. Do not send them to unicom.
👉 SELCAL is done only between Aurora and Altitude. It does not use the simulator aircraft.
Aircraft with SELCAL
Pilot: Shanwick Radio, UAL169, crossing NEBIN, FL320, Mach 085, SELCAL code RL-AH.
ATC: UAL169, roger, standby for SELCAL check RL-AH.
Pilot: SELCAL check positive.
ATC: UAL169, roger, maintain on SELCAL watch. No position reports required.
Aircraft without SELCAL
Pilot: Shanwick Radio, UAL169, crossing NEBIN, FL320, Mach 085, negative SELCAL.
ATC: UAL169, roger, maintain on frequency watch. No position reports required.
The airspace of the North Atlantic (NAT), which links Europe and North America, is the busiest oceanic airspace in the world. In 2012 approximately 460,000 flights crossed the North Atlantic and that volume of traffic continues to increase. Aircraft are now seperated by satelite ADS-B data sent by aircraft automatically every few secons.
The North Atlantic Region encompasses virtually all of the non-domestic airspace over the Atlantic Ocean between roughly 20° north latitude and the North Pole except the airspace of New York Oceanic West. It is divided into a total of 6 Oceanic Control Areas (OCAs) / Flight Information Regions (FIRs). These OCAs / FIRs are as follows:
Embedded within the North Atlantic Region are a number of domestic CTAs / TMAs including:
The north atlantic airspace consist of multiple layers. On the outermost, containing everything, is the NAT region.
Within the NAT region different types of airspace specifications and requirements exist. Most commonly used on IVAO are the NAT Tracks between FL350-390 inclusive.
Real world representation of the NAT layers:
Over the high seas, the lower limit of all NAT oceanic control areas is FL55. There is no upper limit. Airspace at and above FL55 is Class A controlled airspace and below FL55 it is Class G uncontrolled airspace.
All flights operating at or above FL60 must be conducted in accordance with Instrument Flight Rules (IFR), even when not operating in instrument meteorological conditions (IMC). Clearance for Visual Flight Rules (VFR) climb or descent - a climb or descent while maintaining own separation while in Visual Meteorological Conditions (VMC) - will not be issued.
Strategic Lateral Offset Procedures (SLOP) are authorized and encouraged.
Transponders should be operated at all times while in North Atlantic (NAT) region and set to squawk Code 2000. However, the last ATC assigned code must be retained for a period of 10 minutes after entry into NAT airspace unless otherwise directed by ATC.
These procedures in no way affect the use of the special purpose codes 7500, 7600 and 7700.
A large portion of the airspace of the North Atlantic Region, between FLs 285 and 420 inclusive, is designated as the NAT High Level Airspace (NAT HLA).
Within this airspace a formal Approval Process by the State of Registry of the aircraft or the State of the Operator ensures that aircraft meet defined NAT HLA Standards and that appropriate crew procedures and training have been adopted. HLA Standards include the requirement for two approved independent Long Range Navigation Systems (LRNS). It should be noted that State Approvals for NAT MNPS operations granted prior to 04 February 2016 will be valid for NAT HLA operations with the exception that those Approvals issued prior to 01 January 2015 and based upon the earlier “6.3 NMs” MNPS standard, will not be valid beyond January 2020.
The unique, unidirectional, flexible track structure of the North Atlantic Organised Track System (NAT OTS) is located within HLA, predominantly in the Gander and Shanwick Oceanic CTAs.
Read more about HLA airspace here: https://wiki.ivao.aero/en/home/training/documentation/HLA_-_High_Level_Airspace
Aircraft not meeting the navigation requirements for HLA airspace can choose to fly above FL420 or below FL285.
LRNS Aircraft (VOR, DME, ADF)
Additionally, within the HLA, special routes, referred to as Blue Spruce Routes have been designated for aircraft equipped with only one LRNS plus normal short-range navigation equipment (VOR, DME, ADF), which require to cross the North Atlantic between Europe and North America (or vice versa). As these routes are within NAT HLA Airspace, State approval must be obtained prior to flying along them. These routes are also available for interim use by aircraft normally approved for unrestricted NAT HLA operations that have suffered a partial loss of navigation capability and have only a single remaining functional LRNS.
Reduced Vertical Separation Minima (RVSM), in the band of altitudes FL290 - FL410, is applicable in all NAT HLA. Aircraft not RVSM certified will be cleared either above or below RVSM airspace. These aircraft may be cleared to climb or descend through RVSM airspace on a non-interference basis.
ATC may provide special approval for a NAT HLA approved aircraft that is not approved for RVSM operation to fly in NAT HLA airspace provided that the aircraft:
Prior coordination is required.
The objectives of the NAT Data Link Mandate are to enhance communication, surveillance, and air traffic control (ATC) intervention capabilities in the NAT region. ADS-C provides conformance monitoring of aircraft adherence to cleared route and flight level significantly enhancing safety. ADS-C also facilitates search and rescue operations including the capability to locate the site of an accident in oceanic airspace. CPDLC substantially improves air/ground communications capability and therefore controller intervention capability.
DLM airspace encompasses FL290 to FL410 inclusive throughout the NAT region, except the following:
The following flights may flight plan to operate in NAT DLM airspace:
Non-equipped aircraft may request to climb or descend through NAT DLM airspace. Such requests will be
considered on a tactical basis.
Much of the air traffic over the North Atlantic (NAT) is part of two major alternating flows:
This pattern results from time zone differences, airport noise restrictions and, most significantly, passenger demand.
The constraints caused by the large horizontal separation criteria within NAT airspace and a limited economical height band (FL310–400) for most commercial traffic result in airspace congestion during peak hours. In order to provide the best service to the bulk of the traffic, a system of organised tracks is constructed to accommodate as many flights as possible within the major flows on or close to their minimum time tracks and optimum altitude profiles.
The dynamic and ever changing nature of the NAT weather patterns, inclusive of the presence and location of pressure systems and jet streams (bands of strong wind that generally blow from west to east all across the globe), means that eastbound and westbound minimum time tracks can be widely separated and also that day to day variation in the location of these minimum time tracks will occur.
As a result, organised track structures, one for eastbound traffic and one for westbound traffic are created on a daily basis. These track structures are referred to as the Organised Track System (OTS).
Use of OTS tracks is not mandatory. An aircraft may fly on a random route which remains clear of the OTS, or may fly on any route that joins or leaves an outer track of the OTS. Additionally, nothing prevents an operator from planning a route which crosses the OTS.
While the routes change daily, they maintain a series of entrance and exit waypoints which link into the airspace system of North America and Europe. Each route is uniquely identified by a letter of the alphabet.
Westbound tracks (valid from 11:30 UTC to 19:00 UTC at 30W) are indicated by the letters A,B,C,D etc. (as far as M if necessary, omitting I), where A is the northernmost track, and eastbound tracks (valid from 01:00 UTC to 08:00 UTC at 30W) are indicated by the letters Z,Y,X,W etc. (as far as N if necessary, omitting O), where Z is the southernmost track.
Waypoints on the route are identified by named waypoints (or "fixes") and by the crossing of degrees of latitude and longitude (such as "54/40", indicating 54°N latitude, 40°W longitude).
NATs only exist within the HLA.

The correct method is to file a flight plan with an Oceanic Entry Point (OEP), then the name of the NAT Track, e.g. "NAT A" for NAT Track Alpha, and the Oceanic Exit Point (OXP). Example: "... SUNOT NATA LOMSI ..."
A ‘random route’ must have a waypoint every 10 degrees of longitude. Aircraft can also join an outer track half way along.
Since 2017, aircraft can plan any flight level in the NAT HLA (high level airspace), with no need to follow ICAO standard cruising levels.
Daily Tracks

Random tracks are essentially handmade routes across the North Atlantic, using Lat/Lon waypoints, just like the NAT Tracks. Random routes are used where the NAT Tracks are not suitable.
The Concorde did not travel on the North Atlantic Tracks as it flew between 45,000 and 60,000 ft, a much higher altitude than subsonic airliners. The weather variations at these altitudes were so minor that Concorde followed the same track each day. These fixed tracks were known as 'Track Sierra Mike' (SM) for westbound flights and 'Track Sierra November' (SN) for eastbounds, with an additional 'Track Sierra Oscar' (SO) used if necessary.
For historical reason following static tracks are available if included in the flightplan for supersonic aircraft. Do not assign these tracks unless requested or filed. Read more here.

Traditionally, air traffic tracking over land is done via PSR and SSR surveillance.
Primary radar system (PSR) refers to the raw radar return that shows the position of the target but provides no additional information. On the other hand, secondary surveillance radar (SSR) generates computer-generated information that appears alongside the primary radar return, including the aircraft’s callsign, squawk code, altitude, and ground speed.
However, due to the lack of physical radar stations none of these methods can be used for oceanic airspace.
ADS-B service has expanded into oceanic and remote areas facilitated by a constellation of Low Earth Orbit (LEO) satellites hosting ADS-B receivers. A satellite receives ADS-B data including position, velocity and altitude from aircraft, which is then routed through other satellites and down-linked to a satellite operations ground station. The expanded surveillance system will permit uninterrupted ATS surveillance for equipped aircraft before, during and after entry into the North Atlantic (NAT) Region.
Aircraft must meet the following requirements:

Aircraft operating in the New York Oceanic CTA/FIR, excluding that portion of the airspace delegated to NAVCANADA can expect to receive ATC services associated with the following types of airspace areas and associated altitudes:
Class G | Class A | Class E |
---|---|---|
below FL55 | FL55 to FL600 | above FL 600 |
NY Oceanic is responsible for the airspace bordering along the east coast of the United States, Gander and Shanwick in the north, Santa Maria in the east, as well as Piarco and San Juan in the south.
All of ZWY is RVSM airspace. Non-RVSM aircraft are not permitted in RVSM airspace unless they meet the criteria of excepted aircraft and are previously approved by the ATS unit having authority for the airspace.
New York Oceanic serves both as an Oceanic Control Area (OCA) and a Flight Information Region (FIR). In most sectors, air traffic control services are provided to all aircraft flying at or above FL055. Flight information and alerting services only are provided to known aircraft flying below FL055.
The transition altitude in non-radar airspace is FL055
All airspace uses ADS-B Satellite coverage.
The West Atlantic Route System is a high complexity fixed set of tracks which experiences peaks of high traffic density. The WATRS or OCA West airspace in ZWY consists of all of the non-radar airspace south of 38.5 N and west of 60 W. The primary air traffic flows in the WATRS airspace are between Northeast and Mid-Atlantic US airports and Caribbean and South American destinations. This primary flow is regularly crossed by the flow of traffic transitioning to and from the Southeast US / Caribbean and the North Atlantic and New York OCA East airspace.
Altitude assignments in WATRS generally follow the normal FAA assignments based on flight direction. Final altitude assignment will be determined dynamically based on traffic and operational conditions.
Aircraft should file odd flight levels when operating:
South and Southeast bound on on L451, L452, L453, L454, L455, L456, L457, L459, L461, and L462.
Northeast bound on M201, M202, M203, M204.
East or Northeast on L375, L435, M325, M326, M327, M328, M329, M330, M331, M593, M594, M595, M596, M597, and M525.
Aircraft should file even flight levels when operating in the opposite direction of the above routes.
All airspace uses ADS-B Satellite coverage.
OCA East airspace north of 28N is also in the North Atlantic High Level Airspace (NAT HLA). The NAT HLA consists of the airspace from FL285 to FL420 within its lateral boundaries. RNP4 or RNP10 are required.

All information in this section applies to non-radar, oceanic airspace.
Apply the following performance assumptions when providing air traffic control service in ZWY.
All aircraft flying on IVAO are assumed to be:
All aircraft flying in ZWY may be assumed to be the following unless notified by the pilot:
CPDLC is a text communications link between the controller and the pilot. CPDLC in ZWY is simulated via the on-frequency text chat and private text chat.
Space-based ADS-B is not in use at ZWY.
ADS-C uses various systems on board the aircraft to automatically provide aircraft position, altitude, speed, intent and meteorological data, which can be sent in a report to an ATS unit or AOC facility ground system for surveillance and route conformance monitoring.
One or more reports are generated in response to an ADS contract, which is requested by the ground system. An ADS contract identifies the types of information and the conditions under which reports are to be sent by the aircraft. Some types of information are included in every report, while other types are provided only if specified in the ADS contract request. The aircraft can also send unsolicited ADS-C emergency reports to any ATS unit that has an ADS connection with the aircraft.
An ATS unit system may request multiple simultaneous ADS contracts to a single aircraft, including one periodic and one event contract, which may be supplemented by any number of demand contracts. Up to five separate ground systems may request ADS contracts with a single aircraft.
All aircraft flying on IVAO continuously send aircraft position, altitude, and speed data to IVAO servers are available to the controller in the ATC client. ADS-C is simulated by using the "assume" function in Aurora.
Pilots make initial contact via voice by requesting a SELCAL check and stating the next oceanic facility.
[Radio Station Name], [Radio Station Name], [Aircraft Callsign], (Next oceanic facility), SELCAL check [SELCAL Code],
ATC responds by sending a SELCAL, instructions to contact the next facility if applicable, and stating that position reports are not required for ADS-C.
[Aircraft Callsign], [Radio Station Name], [Instructions for next facility]. Position reports not required.
After receiving the SELCAL, the pilot responds with "SELCAL OK" and a readback of any additional instructions.
[Radio Station Name], [Aircraft Callsign], [Readback of instructions].
Example:
AAL123 is flying through New York Oceanic and will enter Gander Oceanic next. The radio is tuned to 130.0.
Pilot: New York, New York, AAL123, Gander next, SELCAL check.
ATC: American 123, New York Radio, at 45 North, contact Gander Radio on 131.5. Position reports not required.
Pilot: New York Radio, AAL123, SELCAL OK, at 45 North contact Gander Radio on 131.5.
Solicit When Able Higher reports for aircraft entering the NAT HLA and when it would provide an operational advantage.
The radio operator asks the aircraft to say when able higher.
[Aircraft Callsign], [Radio Station Name], say When Able Higher.
The pilot responds with a WAH report which consists of altitudes and the time they are able to climb to that altitude.
[Radio Station Name], [Aircraft Callsign], able [Flight Level] at [Zulu Time], able [Flight Level] at [Zulu Time], etc.
Example:
DAL123 is at FL330.
ATC: Delta 123, New York Radio, say When Able Higher.
Pilot: New York Radio, Delta 123, able FL340 at 1300, able FL350 at 1415, able FL370 at 1545.
Information about the ability to climb does not constitute a climb request to ATC. Pilots requesting a higher altitude will replace "able" with "request" in the WAH report.
Example:
DAL123 is at FL330 and requests FL350 at 1415z.
ATC: DAL123, New York Radio, say When Able Higher.
Pilot: New York Radio, DAL123, able FL340 at 1300z, request FL350 at 1415z, able FL370 at 1545z.
Pilots request changes to their oceanic clearance by making a "request clearance" call.
Example:
Pilot: New York Radio, Speedbird 123, request clearance on 130.0.
ATC: Speedbird 123, New York Radio.
Pilot: New York Radio, Speedbird 123, request FL350.
or
Pilot: New York Radio, Speedbird 123, request Mach .82.
Pilots report revised estimates with the same procedure except by saying "revised estimate" in the initial call and only reporting the fix and revised time.
Located in the heart of the Atlantic Ocean, Bermuda Islands is a facility controlled by local control and radar service (CTR/APP). Its airspace handles in and out bounds from Bermuda only, however the call sign remains associated with New York. Flights trespassing this airspace are handled by New York Oceanic
