3. Procedure for Air Navigation Services Operation (PANS-OPS) criteria (based on ICAO Document 8168, Volume II):

3.1 In order to achieve the lowest possible operating minima for aircraft operation, it is necessary to protect not only the Annex 14 OLS but also to safeguard the PANS-OPS [ICAO Document 8168] Surfaces. The limit of PANS-OPS surfaces extend up to 30NM from the facility i.e. VOR or NDB serving the aerodrome. Considerations need to be given to the objects which penetrate the PANSOPS surfaces, regardless whether or not they penetrate Annex 14 OLS. Such obstacle may result in an operational penalty like higher Obstacle Clearance Altitude/Height (OCA/H) and introduction of longer approach segment. Therefore, while examining the cases for issue of NOC from the considerations of Annex 14 and Annex 10 criteria as provided in para 1 and 2 above, the operational criteria needs to be considered based on the provisions of Documents 8168, Vol.-II. It needs to be ensured that the minimum altitudes of the following segments, published or the proposed, are not infringed:

i. Minimum Sector Altitude (MSA)

ii. Minimum Holding Altitude (MHA)

iii. Minimum Vectoring Altitude (MVA)

iv. Minimum Altitude of Initial and Intermediate Segments

v. OCA/H (Straight-in-and Circling) for all aircraft categories

vi. STARs /SIDs procedure altitude.

vii. Basic ILS Surface

3.2 Criterion specified in Doc 8168 Vol. II (PANS-OPS) for designing instrument procedures shall not be used for creating new structures as PANS-OPS surfaces are not intended to replace Annex 14 OLS as planning surfaces for creating new structures."

3.3 For the obstacles located even outside the limits of Annex 14 OLS, it shall be ensured that PANSOPS surfaces of the published instrument approach procedures are not penetrated.

Note 1: Instrument approach procedures of all the civil aerodromes in India have been published in the AIP India under the section “Aerodrome”. In the published procedures, the minimum altitudes of the various segments of instrument approach procedures have been specified.

Note 2: The minimum obstacle clearance criteria are applied as per the provisions of International Civil Aviation Organization (ICAO) Document 8168 Volume II. Normally for minimum sector altitudes (Applicable upto 30 NM from the facility on which procedure is designed), minimum vectoring altitudes, minimum holding altitudes and for the initial approach an obstacle clearance of 1000 feet is applied.

Note 3: Final approach areas of Very High Frequency Omni Radio Range (VOR)/Non Directional Beacon (NDB) have been illustrated in Appendix -E of Schedule VIII).

4. Shielding criteria

The principle of shielding is applicable w.r.t. Natural Terrain, already penetrating one of the obstacle limitation surfaces of an airport and it is not likely to be removed. The shielding criteria as explained below is applicable w.r.t. AGA and CNS surfaces.

4.1 The principle of shielding will not to be applied in:

I. Transitional surface area,

II. Approach surface areas, within 4000 meters of the inner edge of approach surface.

III. Inner Horizontal Surface (IHS), within a distance of 2500 meters from the runway centre line.

In case of multiple runways, area encompassed by 2500M from centerline of all runways.

4.2 The following criteria shall be followed for the purpose of applying shielding criteria for the proposed structure with respect to existing natural terrain.

4.2.1 Proposed (shielded) object located beyond a distance of 2500M from runway centerline:

(i) Draw a line joining the centre point of the plot to the nearest runway end (runway code no. 3 & 4) or ARP (code 1 & 2) as the case may be. Shielding will be applicable w.r.t. applicable terrain within the area bounded by the two lines drawn parallel to the above line, at a
distance of 600M on either side. A line, across the highest point of applicable reference (shielding) terrain, perpendicularly to the above parallel lines shall be drawn to delineate the areas for different type of shielding i.e. negative or equal to the horizontal plane passing through top of reference terrain (For the illustrations refer to Appendix–F and Appendix-G of Schedule VIII).

(ii) If the proposed structure is lying between the aerodrome and the reference terrain, a negative shielding of 10% shall be applicable. The shielding benefit of a horizontal plane, equal to reference terrain height, shall be provided in the area located in the opposite side away from the aerodrome (For the illustrations refer to Appendix–F and Appendix-G of Schedule VIII).

4.3 Communication Navigation Surveillance (CNS) Parameters:

For CNS facilities, shielding benefit could be provided to the structures in cases wherein such structures (shielded) are in the shadow of the highest terrain of permanent nature. Shadow for this purpose is defined as an area falling below a line drawn from the top and both the extremities of the terrain of permanent nature, to the facility and extrapolation of the same plane behind from the said obstacle.

5.2 Communication Navigation Surveillance (CNS) Simulation study: In case any structure is required to be made within aerodrome premises (airside and city side) by the Aerodrome Operator which creates obstruction from CNS point of view, a simulation study could be carried out to study the impact of this structure on the performance of the relevant facility and in case the study confirms that the impact would not hamper the operability of the facility, such structure could be permitted within the aerodrome premises.

6. Procedure for determining the maximum permissible heights:

The following steps shall be taken for calculating the maximum permissible heights for cases where there is a requirement of NOC from AAI or from Defence Authorities.

This has also been referred to at para 3 of this annexure.

6.4.2 The lowest elevation determined as above, based on the OLS, CNS and PANS-OPS criteria, shall be the permissible top elevation of the proposed structure for which No Objection Certificate may be issued by the designated officer of AAI or the Defence Authorities.

6.5 No Objection Certificate Application System (NOCAS) for applying for height clearance w.r.t. Civil Airports:

6.5.1 AAI has introduced “No Objection Certificate Application System (NOCAS)” accessible at the AAI website www.aai.aero for online submission of NOC application for height clearance. NOCAS carries out calculations w.r.t. OLS and CNS criteria based on site coordinates and elevation provided by the applicant. It is mandatory for the applicant to provide surveyed site coordinates in WGS 84 system and site elevation from a Govt. entity or a Govt. approved agency. The applicants are first required to register themselves online and only thereafter, they can submit their applications for NOC. On registering in NOCAS, a NOCAS ID is generated which can be used for future reference including status check of the application. Guidelines for online submission of NOC application for height clearance are available at NOCAS at www.aai.aero.

6.5.2 A table of permissible heights w.r.t. Annex 14 OLS criteria at different distances from the runway (Code 3 or 4 Instrument runway) at an airport are given at Appendix-L of Schedule VIII.

6.6 The permissible heights given therein are only indicative w.r.t. OLS criteria only; detailed calculations w.r.t. CNS and PANS-OPS criteria are needed to arrive at the actual height permissible, which may be lower than the indicated.

(i) To reduce the risk of damage to aircraft running off a runway; and

(ii) To protect aircraft flying over it during take off or landing operations.

(q) Clearway – A defined rectangular area on the ground or water under the control of the appropriate authority selected or prepared as a suitable area over which an aeroplane may make a portion of its initial climb to specified height.

(r) Stopway – A defined rectangular area on the ground at the end of take off run available prepared as suitable area in which an aircraft can be stopped in case of an abandoned take-off.

(s) Take-off Runway – a runway intended for take-off only.

(t) Obstacle Clarence Altitude/Height (OCA/H) – The lowest altitude or the lowest height above the elevation of the relevant runway threshold or the aerodrome elevation as applicable used in establishing compliance with appropriate clearance criteria.

(u) Declared Distances:-

(i) Take Off Run Available (TORA) – The length of the runway declared available and suitable for the ground run of an aeroplane taking off.

(ii) Take Off Distance Available (TODA) – The length of take-off run available plus the length of clearway, if provided.

(iii) Accelerate Stop Distance Available (ASDA) – The length of take-off run available plus the length of stopway, if provided.

(iv) Landing Distance Available (LDA) – The length of the runway declared available and suitable for the ground run of an aeroplane landing.

(v) Critical Area – Critical area is an area of defined dimensions about the localizer and glide path antenna where vehicles including aircrafts are excluded during Instrument Landing System (ILS) operations. The critical area is protected because the presence of vehicles and/or aircraft inside its boundary will cause unacceptable discrepancies to the Instrument Landing System (ILS) signal in space.
