(Paragraph 2.7.1 and Section 2.11 refer)

1. Introduction Note.— Guidance material on overall VOR system accuracy is also contained in Annex 10, Volume I, Attachment C. 1.1 The guidance material in this Attachment results from comprehensive studies, carried out in Europe in 1972 and the United States in 1978, which were in general agreement. 3. Determination of Note.— Details of the European studies are contained in protected airspace along Circular 120 — Methodology for the Derivation of Separation VOR-defined routes Minima Applied to the Spacing between Parallel Tracks in ATS Route Structures. Note 1.— The material of this section has not been derived by means of the collision-risk/target level of safety method. 1.2 In applying the guidance material in 3 and 4, it should be recognized that the data on which it is based are generally Note 2.— The word “containment” as used in this section representative of navigation using VOR meeting the full is intended to indicate that the protected airspace provided requirements of Doc 8071 — Manual on Testing of Radio will contain the traffic for 95 per cent of the total flying time Navigation Aids, Volume I. Any additional factors, such as (i.e. accumulated over all aircraft) for which the traffic those due to particular operational requirements, frequency of operates along the route in question. Where, for example aircraft passings or information available regarding the actual 95 per cent containment is provided, it is implicit that for track-keeping performance of aircraft within a given portion of 5 per cent of the total flying time traffic will be outside the airspace should be taken into account. protected airspace. It is not possible to quantify the maximum distance which such traffic is likely to deviate beyond the 1.3 Attention is also invited to the basic assumptions in protected airspace. 4.2 and to the fact that the values given in 4.1 represent a conservative approach. Before applying these values, account 3.1 For VOR-defined routes where radar is not used to should therefore be taken of any practical experience gained in assist aircraft in remaining within the protected airspace, the the airspace under consideration, as well as the possibility of following guidance is provided.

Determination of VOR system 3.3 The work described in Circular 120 indicates that a performance values VOR system performance based on the probability of 95 per cent containment would require the following protected The large variability of the values which are likely to be airspace around the centre line of the route to allow for associated with each of the factors that make up the total VOR possible deviations: system, and the limitation of presently available methods to measure all these effects individually with the required — VOR routes with 93 km (50 NM) or less between precision, have led to the conclusion that an assessment of the VORs: ±7.4 km (4 NM); total system error provides a more realistic method for determining the VOR system performance. The material — VOR routes with up to 278 km (150 NM) between contained in 3 and 4 should be applied only after study of VORs: ±7.4 km (4 NM) up to 46 km (25 NM) from the Circular 120 especially with respect to the environmental VOR then expanding protected airspace up to ±11.1 km conditions.

3.5 If two segments of a VOR-defined ATS route intersect at an angle of more than 25 degrees, additional protected airspace should be provided on the outside of the turn and also on the inside of the turn as necessary. This additional space is to act as a buffer for increased lateral displacement of aircraft, observed in practice, during changes of direction exceeding 25 degrees. The amount of airspace added varies with the angle of intersection. The greater the angle, the greater the additional airspace to be used. Guidance Figure A-1 is provided for protected airspace required at turns of no more than 90 degrees. For the exceptional circumstances which require an ATS route with a turn of more than 90 degrees, 3.4 If the appropriate ATS authority considers that a States should ensure that adequate protected airspace is better protection is required, e.g. because of the proximity of provided on both the inside and outside of such turns. prohibited, restricted or danger areas, climb or descent paths of military aircraft, etc., it may decide that a higher level of 3.6 The following examples have been synthesized from containment should be provided. For delineating the protected the practices of two States which use templates to facilitate the airspace the following values should then be used: diagramming of airspace for planning purposes. Design of the turning area templates took into account factors such as — for segments with 93 km (50 NM) or less between aircraft speed, bank angle in turns, probable wind velocity, VORs, use the values in line A of the table below; position errors, pilot delays and an intercept angle of at least 30 degrees to achieve the new track, and provides at least — for segments with more than 93 km (50 NM) and less 95 per cent containment. than 278 km (150 NM) between the VORs use the values given in line A of the table up to 46 km (25 NM), 3.7 A template was used to establish the additional then expand linearly to the value given in line B at airspace required on the outside of turns to contain aircraft 139 km (75 NM) from the VOR. executing turns of 30, 45, 60, 75 and 90 degrees. The simplified figures below represent the outer limits of this airspace with the fairing curves removed to allow easy Percentage containment construction. In each case, the additional airspace is shown for aircraft flying in the direction of the large arrow. Where routes 95 96 97 98 99 99.5 are used in both directions, the same additional airspace should A (km) ±7.4 ±7.4 ±8.3 ±9.3 ±10.2 ±11.1 be provided on the other outside boundary.

(NM) ±6.0 ±6.0 ±6.5 ±6.5 ±7.0 ±8.5

For example, the protected area for a route of 222 km (120 NM) between VORs and for which 99.5 per cent containment is required should have the following shape:

From this point on the inner edge of the , construct a line to intersect the airway centre line beyond the turn at an angle of half of the angle of turn.

The resulting triangle on the inside of the turn depicts the additional airspace which should be protected for the change of direction. For any turn of 90 degrees or less, the extra space on the inside will serve for aircraft approaching the turn from either direction.

Note 1.— Criteria for the calculation of the along-track tolerance are contained in PANS-OPS (Doc 8168), Volume II, Part III, Appendix to Chapter 31.

Note 2.— Guidance on the calculation of radius of turn is Figure A-4 provided in Section 7.

However, the figures given centre lines (S in Figure A-7) for distances between VORs of have not been precisely calculated and in each case a detailed 278 km (150 NM) or less should normally be a minimum of: study of the particular circumstances is essential:

b) if the traffic characteristics differ significantly from those contained in Circular 120, the minima contained in 4.1 may require adjustment. For example, for traffic densities of about 10 000 flights per busy two-month period a reduction of 900 to 1 850 m (0.5 to 1.0 NM) may be possible;

c) the relative locations of the VORs defining the two tracks and the distance between the VORs will have an effect on the spacing, but this has not been quantified.

Figure A-7 4.4 Application of radar monitoring and control of the lateral deviations of the aircraft may have a large effect on the minimum allowable distance between routes. Studies on the effect of radar monitoring indicate that: Note.— Two route segments are considered parallel when: — further work is necessary before a fully satisfactory mathematical model can be developed; — they have about the same orientation, i.e. the angular difference does not exceed 10 degrees; — any reduction of separation is closely related to:

— they are not intersecting, i.e. another form of separation — traffic (volume, characteristics); must exist at a defined distance from the intersection; — radar coverage and processing, availability of an automatic alarm; — traffic on each route is independent of traffic on the — monitoring continuity; other route, i.e. it does not lead to restrictions on the — sector workload; and other route. — radiotelephony quality.

5.3 Where there is an angular difference of more than 7.2 Turn performance is dependent on two parameters — 25 degrees between route segments, additional protected ground speed and bank angle. Due to the effect of the wind airspace, as indicated in 3.5 to 3.10, should be provided. component changing with the change of heading, the ground speed and hence bank angle will change during a constant radius turn. However, for turns not greater than approximately 90 degrees and for the speed values considered below, the following formula can be used to calculate the achievable constant radius of turn, where the ground speed is the sum of the true airspeed and the wind speed:

Radius of turn = (Ground speed)2 Constant ‘G’ * TAN(bank angle)

7.3 The greater the ground speed, the greater will be the required bank angle. To ensure that the turn radius is represen- tative for all foreseeable conditions, it is necessary to consider extreme parameters. A true airspeed of 1 020 km/h (550 kt) is considered probably the greatest to be encountered in the upper levels. Combined with maximum anticipated wind speeds in the medium and upper flight levels of 370 km/h (200 kt) [99.5 per cent values based on meteorological data], a maximum ground speed of 1 400 km/h (750 kt) should be considered. Maximum bank angle is very much a function of individual aircraft. Aircraft with high wing loadings flying at or near their maximum are highly intolerant of Figure A-8 extreme angles. Most transport aircraft are certified to fly no

Because the stall speed rises with TAN(bank with a tailwind of 370 km/h (200 kt). Keeping the maximum angle), many operators try not to cruise below 1.4 times the bank angle of 20 degrees, and following the same formula, the stall speed to protect against gusts or turbulence. For the same turn would be defined along a radius of 14.45 NM (26.76 km). reason, many transport aircraft fly at reduced maximum angles For expediency, this figure may be rounded up to 15 NM of bank in cruise conditions. Hence, it can be assumed that the (27.8 km). highest bank angle which can be tolerated by all aircraft types is in the order of 20 degrees. 7.5 Given the above, the most logical break point between the two ground speed conditions is between FL 190 7.4 By calculation, the radius of turn of an aircraft flying (5 800 m) and FL 200 (6 100 m). In order to encompass the at 1 400 km/h (750 kt) ground speed, with a bank angle of range of turn anticipation algorithms used in current flight 20 degrees, is 22.51 NM (41.69 km). For purposes of management systems (FMS) under all foreseeable conditions, expediency, this has been reduced to 22.5 NM (41.6 km). the turn radius at FL 200 and above should be defined as Following the same logic for the lower airspace, it is 22.5 NM (41.6 km) and at FL 190 and below as 15 NM considered that up to FL 200 (6 100 m) the maximum figures (27.8 km).

25/2/05 SUPPLEMENT TO ANNEX 11 (THIRTEENTH EDITION) SWEDEN 1

CHAPTER 1

Definitions Approach control unit. The term “approach control unit” is not used; instead, the term “terminal control centre (TMC)” is used to designate a unit established to provide air traffic control service to controlled flights arriving at, or departing from, one or more aerodromes.

CHAPTER 2

2.3.2 Aerodrome flight information service (AFIS) is provided at several non-controlled aerodromes as published in AIP-SWEDEN.

Remark. AFIS, as well as AFIS units, has been established for many years as published in AIP- SWEDEN. AFIS is generally provided in conformance with the guidance material contained in ICAO Circular 211.

2.6 Within Class G airspace, traffic information areas (TIA) and traffic information zones (TIZ) are established at several non-controlled aerodromes where AFIS is provided. These airspaces are described in AIP-SWEDEN and defined as follows:

Traffic information area (TIA). An uncontrolled airspace of defined dimensions extending upwards from a specified limit above the earth within which traffic information is provided by an ATS unit in accordance with special regulations.

Traffic information zone (TIZ). An uncontrolled airspace of defined dimensions extending upwards from the surface of the earth to a specified upper limit within which traffic information is provided by an ATS unit in accordance with special regulations.

Remark. These airspace designations were implemented several years before the publication of ICAO Circular 211. It has not been considered that there is enough justification to change the airspace designation to “flight information zone” as recommended in the circular.

2.8 AFIS units are established at several non-controlled aerodromes for the provision of aerodrome flight information service as published in AIP-Sweden.

Remark. AFIS, as well as AFIS units, has been established for many years as published in AIP- SWEDEN. AFIS is generally provided in conformance with the guidance material contained in ICAO Circular 211.

2.9 Within Class G airspace, traffic information areas (TIA) and traffic information zones (TIZ) are established at several non-controlled aerodromes where AFIS is provided. These airspaces are described in AIP-SWEDEN and defined as follows:

Traffic information area (TIA). An uncontrolled airspace of defined dimensions extending upwards from a specified limit above the earth within which traffic information is provided by an ATS unit in accordance with special regulations.

Traffic information zone (TIZ). An uncontrolled airspace of defined dimensions extending upwards from the surface of the earth to a specified upper limit within which traffic information is provided by an ATS unit in accordance with special regulations.

31/12/03 SWEDEN 2 SUPPLEMENT TO ANNEX 11 (THIRTEENTH EDITION)

Remark. These airspace designations were implemented several years before the publication of ICAO Circular 211. It has not been considered that there is enough justification to change the airspace designation to “flight information zone” as recommended in the circular.

2.21 Minimum flight altitudes have not been determined for control areas; however, for ATS routes within SUECIA CTA, published lower limits provide minimum clearance above the controlling obstacle located within the area concerned. In terminal control areas, minimum sector altitudes are applied as minimum flight altitudes; in addition, minimum vectoring altitudes have been established.

Remark. Determining minimum flight altitudes for ATS routes is considered superfluous since all ATS routes have their lower limits at FL 95 or higher, which is well above terrain and obstacles within Swedish territory. Within TMAs, minimum sector altitudes and minimum vectoring altitudes are considered sufficient.

2.24.4 Aerodrome control towers normally provide pilots with the correct time on request only.

Remark. Since modern clocks and watches are considered very reliable and several methods are available to pilots to verify the correct time prior to departure, and also in order to reduce the load on control tower radio frequencies, routine provision of the correct time has been deleted.

Appendix 4 Within Class E airspace, during hours of darkness, VFR flights are subject to air traffic control service and separated from IFR and other VFR flights; dual radio communication and ATC clearance are required.

Remark. To enhance flight safety in Class E airspace during hours of darkness (night).
