1.1 Surveillance service will usually be provided as an integrated part of the service by a controlled air traffic service unit. Many factors, such as surveillance coverage, controller workload and equipment capabilities may affect this service. The air traffic controller will, on a case to case basis, determine if surveillance service shall be provided.

1.2 The surveillance equipment used in Norwegian airspace is: PSR (Primary Surveillance Radar), SSR (Secondary Surveillance Radar), ADS-B (Automatic Dependent Surveillance - Broadcast), WAM (Wide Area Multilateration) and M-LAT (Local Multilateration).

1.3. All ACC sectors, APP and controlled TWR, except Andøya TWR/APP, provide surveillance service during the published opening hours.

1.3.1 For practical reasons surveillance service provided by TWR may be limited.

1.3.2 Brønnøy AFIS and Røst AFIS provide flight information service within their TIZ based on surveillance data.

1.3.3 Ekofisk HFIS and Tampen HFIS provide flight information service within their HTZ based on surveillance data.

1.4 Identification of aircraft for surveillance service is achieved according to provisions in BSL G 8-1 (implementing ICAO Doc 4444 (PANS-ATM)). Phraseology used will be according to ICAO Doc 4444. The phrase “IDENTIFIED” will be used for all types of surveillance service, and “RADAR CONTACT” will be used only for surveillance service based on radar.

1.5 Automatic termination of surveillance service
Surveillance service is automatically terminated in cases listed under a) and b) below. The phraseology “RADAR SERVICE (or IDENTIFICATION) TERMINATED” will normally not be used in these circumstances.

a) When an aircraft, which had been vectored on to final approach for an instrument approach, has landed.
b) When the control of an aircraft conducting a visual approach is transferred to the control tower.

2.1 Transponder operating procedures

2.1.1 When an aircraft carries a serviceable transponder, the pilot shall operate the transponder at all times, regardless of whether the aircraft is within or outside airspace where surveillance is used for ATS purposes.

2.1.2 Except as specified in para 4.1, 4.2, and 4.3 in respect of emergency, communication failure or unlawful interference, the pilot shall:

a) operate the transponder and select codes as individually directed by the ATS unit with which contact is being made; or

b) unless otherwise directed by ATS, operate the transponder on the last assigned code; or

c) in the absence of any ATS directions, select SSR-code as follows:

• IFR-flights code 2000
• VFR-flights code 7000
• Gliders code 7100
• Unmanned aircraft code 7200 (UAV/UAS, RPAS)
• Helicopter ambulance flights code 5200
• Helicopter police service code 5300

2.1.3 When the aircraft carries serviceable mode C equipment, the pilot shall continuously operate this mode, unless otherwise directed by ATS.

2.1.4 When flying in a formation, only the formation leader shall operate the transponder, unless otherwise directed by ATS.

2.1.5 When requested by ATS to specify the type of transponder carried aboard the aircraft, pilots shall indicate this by inserting the specified characters under item 10 in the flight plan formula;

• E, H, I, L, P, S, X in use for mode S transponder
• B1, B2, (U1, U2, V1, V2) for ADS-B-transponder
• D1, G1 for ADS-C transponder

2.1.6 When requested by ATS to “CONFIRM SQUAWK (code)”, the pilot shall verify the code setting on the transponder, reselect the assigned code if necessary, and confirm the setting displayed on the controls of the transponder.
Note: For action in case of unlawful interferences, REF para 4.3.2

2.1.7 When mode C is in use, and report of level information is required, level information shall be given to the nearest 100 FT (30 M) as indicated on the altimeter.

2.1.8 Pilots shall not SQUAWK IDENT unless requested by ATS.

2.1.9 Position reports
Flights operating along ATS-routes with compulsory reporting points, shall omit position reports when the pilot is informed that the aircraft is provided with surveillance service REF GEN 1.8

3.1 System description
ADS-B is a function on-board an aircraft that periodically transmits data like identification position, velocity and other information. The data link used for ADS-B messages in Europe is 1090 MHZ Extended Squitter. The aircraft position is determined by the use of GNSS. The broadcasted ADS-B messages are received by a network of ADS-B Ground Stations, processed and sent to the ATM systems to be presented on the Situation Data Display (SDD) used by ATS.

3.2 The requirement for ADS-B in Norwegian offshore helicopter operations can be found in “BSL D 2-10 Forskrift om krav til sporing av helikoptre på norsk kontinentalsokkel”.

3.3 Emergency procedures, REF para 4.1

3.4 Communication failure, REF para 4.2

3.5 Unlawful interference procedures, REF para 4.3

3.6 Aircraft Identification
ADS-B has a function on-board an aircraft that periodically transmits parameters including identification (Flight ID) and Mode A/C SSR- code. Norwegian ATM-systems are not yet able to utilize identification by use of Flight ID.

The use of mode A/C SSR code for identification, REF para 2.1.1

3.7 Voice and position reporting, REF para 2.1.9

4.1 Emergency procedures

4.1.1 The pilot of an aircraft encountering a state of emergency shall set the transponder to code 7700 except when previously directed by ATS to operate the transponder on a specified code. In the latter case the pilot shall maintain the specified code unless otherwise instructed.

4.1.2 Notwithstanding the procedures in para 4.2.1, a pilot may select code 7700 whenever there is a specific reason to believe that this would be the best course of action.

4.2 Communication failure procedures

4.2.1The pilot of an aircraft losing two-way communications shall set the transponder to code 7600.

Note: A controller observing a response on the communications failure code 7600 will ascertain the extent of the failure by instructing the pilot to SQUAWK IDENT or to change code. Where it is determined that the aircraft receiver is functioning, further control of the aircraft will be continued using code changes or IDENT transmission to acknowledge the receipt of clearances issued.

4.3 Unlawful interference with aircraft in flight

4.3.1 Should an aircraft in flight be subject to unlawful interference, the pilot-in-command shall endeavour to set the transponder to code 7500 to give indication of the situation unless circumstances warrant the use of code 7700.

4.3.2 A pilot, having selected code 7500 and subsequently requested to confirm this code by ATS in accordance with 2.1.6, shall, according to circumstances, either confirm this or not reply at all.

Note: The absence of a reply from a pilot will be taken by ATS as an indication that the use of code 7500 is not due to an inadvertent false code selection.

For air traffic operating on the Norwegian Continental Shelf, QNH setting areas are established. When flying within these areas, altimeter setting is based on observed local QNH from a METAR station in the area.

ATS will state the QNH for the areas via radio transmission. When crossing a border between QNH areas, the altimeter setting shall be changed when informed by ATS.

QNH-regions are established at Tromsøflaket and Bjørnøya. When flying within these regions, altimeter setting is based on the forecasted minimum QNH in the QNH region.

4.1 QNH setting areas, North Sea

4.1.1 Division of QNH setting areas
The part of Norway FIR described in AIP Norway ENR 2.2 that includes the North Sea Area south, west and north of the horizontal limits of Sola TMA and Flesland TMA, and in Norway CTA west of Møre TMA, is divided into six QNH setting areas where observed QNH shall be used for flights at or below 3000 FT, REF ENR 6.4-9:
• Ekofisk QNH setting area
• Flesland QNH setting area
• Florø QNH setting area
• Gullfaks QNH setting area
• Sleipner QNH setting area
• Sola QNH setting area

4.1.2 Determination of Transition Level in Ekofisk, Balder and Statfjord CTA

Ekofisk CTA includes:
• Sola QNH setting area
• Ekofisk QNH setting area

The ADS areas are established to encompass the helicopter routes (HR) on the Norwegian Continental Shelf between the land bases Sola, Flesland, Florø, Kvernberget and Brønnøysund and the oil fields Ekofisk, Sleipner, Heimdal, Statfjord, Heidrun and Norne. Within the ADS areas Flight Information Service and Alerting Service are provided based on ADS and radar surveillance. All ADS equipped aircraft within an ADS area will normally proceed on direct track from the land base to the destination under continuous surveillance by ATS. Aircraft exempted from the ADS requirement shall within an ADS area proceed on the HR. None-ADS equipped aircraft planning to enter an ADS area are requested to establish two-way communication with the appropriate ATS unit before entering the area, to receive Flight Information within the ADS area.

A HTZ is established at all permanent offshore installations with landing pad on the Norwegian continental shelf, in order to indicate the performance of frequent helicopter approaches and departures and the provision of flight information and alerting service. The services may be provided by a HFIS unit if such unit is established.

A HTZ is established within a radius of 5 NM from the landing pad and comprises the airspace between sea level and 2000 FT AMSL, or to the lower limit of a CTA. Around groups of two or more installations with landing pad, and with distance of less than 10 NM from each other, a common HTZ is established with the border tangential to a 5 NM radius from the landing pads.

REF The Framework Regulations of the Petroleum Act §6 Definitions.

A geographically delimited area surrounding an offshore facility where unauthorised vessels are forbidden to wait, pass through or conduct operations, i.e. vessels that play no part in the licensees' petroleum activities or that have not been given full or restricted access by authorities or licensees, also including aircraft. Unless otherwise stipulated by the King in Council, the zone extends from the seabed to maximum 500 metres above the highest vertical point of a facility.

Horizontally, the zone extends 500 metres from the extreme points of the facility, wherever they may be. The zone does not limit activities which are specifically permitted in accordance with the Petroleum Act or which constitute official business.
