REPUBLIC OF IRAQ REGULATIONS Made by the Authority with the approval of the Director General of Iraqi Civil Aviation Authority under The Civil Aviation Act no. 148 of 1974. 1. Citation REGULATIONS NO.(31) RVSM Citation 1.1 These Regulations may be cited as (RVSM) Regulations. 2. Definitions and Acronyms Definitions and Acronyms 2.1 In these Regulations: Altimetry system error The difference between the altitude indicated by the altimeter display, assuming a correct altimeter barometric setting, and the pressure altitude corresponding to the undisturbed ambient pressure. Altimetry system error stability Altimetry system error for an individual aircraft is considered to be stable if the statistical distribution of altimetry system error is within agreed limits over an agreed period of time. Altitude The vertical distance of a level, point or an object considered as a point, measured from mean sea level. Assigned altitude deviation The difference between the transponded Mode C altitude and the assigned altitude/flight level. Automatic altitude-control system A system that is designed to automatically control the aircraft to a referenced pressure altitude. Collision risk The expected number of mid-air aircraft accidents in a prescribed volume of airspace for a specific number of flight hours due to loss of planned separation. One collision is considered to result in two accidents. 1

Height The vertical distance of a level, a point or an object considered as a point, measured from a specified datum. Height-keeping performance The observed performance of an aircraft with respect to adherence to flight crew prescribed flight level. This includes both technical and operational errors. Large height deviation any vertical deviation of 90 metres/300 feet or more from the flight level expected to be occupied by the aircraft. Non-compliant aircraft An aircraft configured to comply with the requirements of the RVSM MASPS which, through height monitoring, is found to have a total vertical error or an assigned altitude deviation of 90 m (300 ft) or greater, or an altimetry system error greater than 75 m (245 ft). Operational error Any vertical deviation of an aircraft from the correct flight level as a result of incorrect action by ATC or the flight crew. Overall risk The risk of collision due to all causes, which includes the technical risk (see definition) and the risk due to operational errors and in-flight emergencies. RVSM airworthiness approval The process by which the State authority ensures that aircraft meet the RVSM minimum aviation system performance specification (MASPS). Typically, this would involve an operator meeting the requirements of the aircraft manufacturer s service bulletin for the aircraft and having the State authority verify the successful completion of this work. RVSM approval The term is used synonymously with RVSM operational approval. RVSM operational approval The process by which the State authority ensures that an operator meets all the requirements for operating aircraft in RVSM airspace. RVSM airworthiness approval is a prerequisite for operational approval. Target level of safety A generic term representing the level of risk which is considered acceptable in particular circumstances. Technical risk The risk of collision associated with aircraft technical height-keeping performance, which specifically refers to the performance affected by the avionics of the aircraft, not the flight crew. Total vertical error The vertical geometric difference between the actual pressure altitude flown by an aircraft and its assigned pressure altitude (flight level). 2

Track The projection on the earth s surface of the path of an aircraft, the direction of which path at any point is usually expressed in degrees from North (true, magnetic, or grid). 2.2 The following acronyms are used in these regulations: (a) AAD Assigned altitude deviation (b) ACAS Airborne collision avoidance system (c) ADS-B Automatic dependent surveillance broadcast (d) ADS-C Automatic dependent surveillance contract (e) ASE Altimetry system error (f) ATC Air traffic control (g) ATS Air traffic services (h) CRM Collision risk model (i) (j) FIR Flight information region GMU GPS-based monitoring unit (k) GPS Global positioning system (l) HME Height-monitoring equipment (m) HMU Height-monitoring unit (n) LHD Large height deviation (o) MASPS Minimum aircraft system performance specification (p) MIDRMA Middle East Regional Monitoring Agency (q) MLAT Multilateration (r) MMR Minimum monitoring requirements (s) RMA Regional monitoring agency (t) RVSM Reduced vertical separation minimum 3

Scope and Applicability Scope of these Regulations 3.1 Scope 3.1.1 This regulation addresses the required equipment, the approvals and the conditions of operational procedures. 3.1.2 This regulation establishes the minimum acceptable requirements. Applicability of these Regulations 3.2 Applicability 3.2.1 This regulation applies to all Iraqi registered aircraft planning to operate in RVSM airspace. 4. Requirements for RVSM Operations Requirements 4.1 Aircraft Equipment 4.1.1 All aircraft intending to operate in RVSM airspace must, as a minimum have the following equipment, subject to ICAA Airworthiness approval: (a) Two independent altitude measurement systems. Each system should be composed of the following elements; (i) Cross-coupled static source/system, provided with ice protection if located in areas subject to ice accretion. (ii) Equipment for measuring static pressure sensed by the static source, converting it to pressure altitude and displaying the pressure altitude to the flight crew. (iii) Equipment for providing a digitally coded signal corresponding to the displayed pressure altitude, for automatic altitude reporting purposes. (iv) Static source error correction, if 4

needed to meet performance requirements; and (v) The equipment should provide reference signals for automatic control and alerting at a selected altitude. These signals should preferably be derived from an altitude measurement system. (b) One SSR altitude reporting transponder. If only one is fitted, it should have the capability for switching to operate from either altitude measurement system. (c) (d) An altitude alert system. An automatic altitude control system. 5. Approvals (e) ACAS Version II (TCAS Version 5. 5. Approvals 5.1 Approval to operate in RVSM airspace 5.1.1 At least 60 days prior to the intended start date of RVSM operations, an operator shall provide to the ICAA for evaluation; (a) Airworthiness Documents. Documentation shall be provided to demonstrate that the aircraft has been approved for RVSM by the appropriate airworthiness authorities (eg; State of Manufacture). This documentation must be either the Aircraft Flight Manual (AFM), Service Bulletin (S/B) or Supplemental Type Certificate (STC). (b) Description of Aircraft Equipment A description of the aircraft equipment appropriate to operations in an RVSM environment. (c) Maintenance. At the time application is made for operational approval, the operator shall submit a maintenance programme for approval. The programme must address continuing airworthiness procedures. (d) All operators shall submit training syllabi 5

and other appropriate material to the ICAA to demonstrate that the operating practices, procedures and training items related to RVSM operations are incorporated in initial, and where appropriate, recurrent training programmes. (e) Appropriate operator s manuals and checklists shall be revised to include information on standard operating procedures in RVSM airspace, including identification of any operating restrictions established for that aircraft group. 5.2 Overflight Assessment 5.2.1 After the ICAA has granted airworthiness approval, operators should take steps to overfly one of the Height Monitoring Units near Linz, Austria, Nattenheim, Germany or Geneva, Switzerland where the monitoring process results are automatically transmitted to the EUR RMA who then forwards such information to all RMAs. Alternatively, overflight assessments can be conducted by any RMA and such an assessment is acceptable to the ICAA. 5.3 Final Approval Process 5.3.1 T he final step of the approval process may require a validation flight through RVSM airspace with a ICAA Flight Operations Inspector to verify that all relevant procedures are applied effectively. If the performance is satisfactory, operational approval for RVSM airspace may be granted. If the performance is not adequate, then approval will be delayed. 5.3.2 Approval to operate in RVSM airspace will be granted by a Letter of Approval issued by the ICAA. Each aircraft type group for which the operator is granted authority will be listed in the Letter of Approval. Approvals will be valid for 2 years and will require verification of height keeping accuracy for renewal. 6. Operator / ICAA Oversight Oversight 6.1 Operator Responsibilities 6.1.1 Every operator must take immediate action to 6

rectify the conditions that cause any height-keeping errors. The operator shall also report the event to the ICAA within 72 hours, with initial analysis of causal factors and measures taken to prevent further events. 6.1.2 Errors that shall be reported to the ICAA and investigated are: (a) Total Vertical Error, which is the vertical geometric difference between the actual pressure altitude flown by an aircraft and its assigned pressure altitude (flight level) equal to or greater than ± 300 ft (± 90 m). (b) Altimetry System Errors, which is the difference between the pressure altitude displayed to the flight crew when referenced to ISA standard ground pressure setting of 1013.2 hpa, and the free stream pressure altitude, equal to or greater than ± 245 ft (± 75 m). (c) Reported Assigned Altitude Deviation, which is the difference between the transponder Mode C altitude and the assigned altitude flight level, equal to or greater than ± 300 ft (± 90 m). (d) Operational errors. 6.1.3 The operator shall advise the ICAA of any rectification work or modifications, which may affect RVSM capability. 6.1.4 The operator shall ensure that the correct equipment suffix, and additional information if required, is included in flight plans of any aircraft intending to operate in RVSM airspace. 7. Investigation Investigation 7.1 ICAA Action 7.1.1 The ICAA may revoke RVSM approval if; (a) An operator consistently incurs equipment or operational errors. (b) The operator response to a height-keeping error is not effective or timely. 7 XVIII

( c ) An operator shows a history of operational and/or airworthiness errors, then approval may be revoked until the root causes of these errors are shown to be eliminated and RVSM programmes and procedures effective. 7.1.2 Should RVSM approval be withdrawn, notification shall be sent to the appropriate RMA. 7.2 Reinstatement 7.2.1 Following any rectification work the operator would again be expected to demonstrate compliance with the RVSM requirements for monitoring by an independent height monitoring system. 8
