SECTION 1: CO-ORDINATION ARRANGEMENTS (GENERAL) 1. The pilot/operator is requested to telephone the ATC authorities at Section 2 prior to departure in order to notify or update the sortie details including area(s) of operation and planned levels (quoting the ACN Reference). A minimum of 24 hours notice should be given unless specified in Section 2. 2. There may be other aircraft and/or activities outside Controlled/Regulated Airspace unknown to ATC. 3. The carriage of a serviceable transponder (including Mode C ) has been specified. 4. The pilot will be responsible for obtaining all necessary ATC clearances and for maintaining R/T contact with appropriate ATC authorities. 5. The pilot/operator will be responsible for obtaining prior clearances to enter any UK Danger Areas affected by the flight profile from the appropriate Range Control Authority unless this is specifically detailed in Section 2. 6. Other Unusual Aerial Activities (UAAs) may be notified to SARG and may take place within the airspace encompassed by this survey. The pilot/operator is to ensure that UK Daily NOTAM Nav Warnings are consulted prior to each flight. 7. All flights within Controlled Airspace are subject to the requirements of a Flight Plan in accordance with UK AIP ENR1.10. The ACN Reference should be entered into Field 18 of the Flight Plan together with any relevant special handling codes. 8. Flight prioritisation and Non-Deviating Status is in accordance with the information specified on the ACN Cover. Such status may be afforded to part or all of the flight see Section 2. 9. Availability of an ATS from Swanwick (Mil) or Western Radar is subject to unit capacity, priorities and limitations of radar and radio coverage. Minimum pre-flight notification as per UK AIP ENR 1.6 unless otherwise specified in Section 2 of this ACN. PUBLICATIONS AND CHANGES 10. The activity area may lie within Controlled and Uncontrolled Airspace as well as airspace reserved for military use. Aircrew are to thoroughly familiarise themselves with UK airspace structures and procedures, in particular those laid down within the UK Aeronautical Information Publication (UK AIP), ENR 1.1 and be fully conversant with UK Flight Information Services in accordance with UK CAP 493 (MATS Pt 1). 11. The CAA VFR 1:500,000 and 1:250,000 charts and the UK AIP ENR 5 depict some, but not all aviation activity sites and amendments should also be checked. Please refer to http://www.natsuk.ead-it.com 12. This ACN details specific coordination essential to the activity taking place and does not remove the need for aircraft operators to comply with national flight planning and notification procedures. Pilots and ANSPs are required to ensure that all related aviation sites are aware of this planned activity and of subsequent changes not captured within this document. 13. The Sponsor or Event Organiser should co-ordinate any changes to this ACN with SARG quoting the ACN Reference at the top of the page. SECTION 2: CO-ORDINATION ARRANGEMENTS (SPECIFIC) 14. The Monopulse Secondary Surveillance Radar (MSSR) situated at RAF Shawbury, Shropshire requires regular airborne calibration. This task is conducted by the Event Sponsor. Page 2 of 5
15. At least five working days prior to the calibration the Event Sponsor is to contact RAF Valley ATC Supervisor to discuss calibration/engineering arrangements. 16. Calibration Profile: a. The RAF Valley MSSR head is situated at RAF Mona, Anglesey (531531N 0042225W) and the antenna head is 272ft AMSL. Calibration flights will be flown at 5,000ft and 20,000ft above the antenna radar head D value 1 b. Up to eight runs at each level on a radial within an arc between radials 180 T clockwise to 215 T, or within an arc between radials 315 T clockwise to 010 T, range from overhead the facility to 80nm. Some runs will be between 40nm and 80nm. c. Up to two 10nm orbits (clockwise and anticlockwise) at 4,000 ft QNH. d. Operational constraints require a maximum of 5 of drift angle to maintain a known antenna pattern, hence the aircraft captain may request, subject to Air Traffic Control approval, radials not covered by this ACN. 17. For those runs within the arc between radials 180 T clockwise to 215 T, the sponsor/ aircraft captain is requested to also telephone Aberporth Information, giving full details of the flight profile. 18. Any calibration radials at 20,000 ft within the arc between radials 180 T clockwise to 215 T are likely to penetrate ATS Route L18. If it is necessary for those radials to be flown when L18 is notified as active, penetration of the ATS Route will be tactically co-ordinated between Swanwick (Mil) and Aberporth Information (as appropriate) and the LAC (Swanwick) Operations Supervisor. In these circumstances, the sponsor/ aircraft captain must telephone the LAC (Swanwick) Operations Supervisor (01489 612420), at least one hour prior to departure, giving full details of the flight profile. 19. The sponsor/ aircraft captain is responsible for co-ordinating with Dublin ACC Station Manager for penetration of those parts of ATS Routes L18, L70 and L975 where ATS is delegated to Dublin ACC. 20. Some of the 5,000 ft runs in the 315 T clockwise to 010 T arc may infringe the Isle of Man CTR/ CTA. In these circumstances, the sponsor/aircraft captain is required to telephone Isle of Man ATC (01624 827548), at least one hour prior to departure, giving full details of the flight profile. 21. Temporary Reserved Areas (TRA) - the 20,000 ft runs in the 315 T clockwise to 010 T arc may penetrate TRA 004. The aircraft captain/sponsor is responsible for complying with the access requirements specified in UK AIP ENR 1.1.5, paragraph 1.5. 22. The activity also infringes the Valley ATA/ AIAA and North Wales MTA. 23. It is the responsibility of the aircraft captain/sponsor to obtain clearance into/suppression of Danger/ Prohibited/ Restricted Areas affected by the activity. 24. The calibration aircraft will not be RVSM compliant. 25. Non-Deviating Status is approved for those parts of the calibration within controlled airspace. 26. This ACN is PERMANENT and will not be routinely amended. It replaces ACN 2015-00-0131, dated 2 Jan 15, which should be deleted. 1 D Values are corrected from ICAN standard atmosphere to actual conditions, thus aircraft on inbound leg may be unable to maintain whole Flight Levels.
