Cabinet of Ministers Regulations No. 1041 in Riga in 2005 (27 December. 77 65. §) rules on aircraft operating restrictions at airports according to the environmental protection requirements Issued in accordance with the law "on the air" 1. the provisions of article 24 determines the aircraft operating restrictions at airports according to the environmental protection requirements.
2. These rules are applicable to aerodromes where more than 50000 aircraft flight (takeoff or landing) in any calendar year, and concerns for civil subsonic jet aeroplanes with a maximum certificated take-off mass of 34000 kg or more, or having a certified maximum internal equipment for the aeroplane type for more than 19 passenger seats (hereinafter – civil subsonic jet aeroplanes).
3. the scope of these provisions to existing issues, the competent authority is the national agency of Civil Aviation Agency "(hereinafter referred to as the Civil Aviation Agency).
4. Civil subsonic jet aeroplane noise impacts assessed according to aerodrome regulations prescribed environmental noise assessment procedures and requirements.
5. the objective of these regulations implement a balanced approach-environment appropriate operation of aeroplanes, aerodrome adjacent areas of planning, use and control, as well as a special aircraft operating procedures and restrictions.
6. operational planning restrictions on a specific airfield, Civil Aviation Agency to assess such possible financial impact, advantages and disadvantages, taking into account the specific characteristics of the aerodrome.
7. operating limits are from civil subsonic jet aeroplanes operating partly limiting depending on the period, as well as the prohibition on the use of marginally compliant aircraft in the aerodrome concerned.
8. Minimum requirements according to the aircraft's civil subsonic jet aeroplanes that comply with the Convention on international civil aviation Annex 16, volume 1, part II chapter 3 certification limits, with the cumulative margin of not more than five EPNdB (effective perceived noise in decibels) cumulative margin is the figure expressed in EPNdB (effective perceived noise in decibels), and obtained by adding each of the three reference noise measurement points, the resulting difference between the certified noise level and the maximum permitted noise level.
9. the operational limits established taking into account the noise of aircraft found in the certification procedure, if it was made in accordance with the provisions of the Convention on international civil aviation Annex 16 volume 1.
10. Civil Aviation Agency operating restrictions shall apply, having regard to the provisions mentioned in the annex to these factors.
11. to prevent marginally compliant aircraft operating in the airfield, by all measures, the Civil Aviation Agency can introduce additional operating restrictions in the following way: s UR11.1.se months after the completion of the assessment and decision on the introduction of an operating restriction with the minimum requirements of the respective aircraft performed flight number may not exceed the corresponding period of the previous year;
11.2. as from six months after these regulations 11.1. the implementation of the measures referred to in subparagraph, each aircraft operator may be required to reduce the minimum requirements according to the number of aircraft in the airfield at least 20% of the initial total number of such flights a year.
12. Civil Aviation Agency may authorize flights with marginally compliant aircraft if they are exceptional in nature and if flights are not made, for commercial purposes the plane moving the necessary maintenance, repair or operation.
13. The provisions of paragraph 10 and 11 apply after consultation with interested parties. Interested parties are persons affected or may be affected by, or having a legitimate interest in the noise reduction measures, including the introduction of operating restrictions.
14. the Civil Aviation Agency, the introduction of new operating restrictions, give public notice to interested parties, which include the introduction of the reason explanation: UR14.1.se s months before this rule 11.1. the measures laid down in (c);
14.2. one year before this rule 11.2. the measures laid down in (c);
14.3. If these provisions are implemented, the measures laid down in paragraph 11, two months before the flight planning effort for the relevant period.
15. Civil Aviation Agency shall immediately inform the European Commission and all the European Union, the competent authorities of the Member States on the introduction of operating restrictions at airports of the Republic of Latvia.
16. Civil subsonic jet aeroplanes of national joint stock company "Riga International Airport" following departure noise reduction procedure: 16.1 up to 1500 feet above ground to reach the plane flies at a speed relative to the minimum maneuvering speed (V2) increased by 10-20 knots, and the flaps are the take-off position;
16.2. reaching 1500 feet above ground, and flaps to retract the airplane continues to pick up.
17. the rules shall enter into force on January 1, 2006.
Informative reference to European Union Directive provisions included in the law arising from the European Parliament and of the Council of 26 March 2002 Directive 2002/30/EC on the establishment of rules and procedures with regard to the related operating restrictions at Community airports with noise.
Prime Minister a. Halloween traffic Minister a. shlesers Editorial Note: rules shall enter into force on January 1, 2006.
 
Annex a Cabinet of 27 December 2005, the Regulation No 1041 operational constraints in factors 1. analysis of the situation, taking into account: 1. the airport location, capacity, the airport neighborhood characteristics, air traffic and nature;
1.2. environmental quality requirements for the airport and the region concerned;
1.3. during the current and previous years of noise contours and their calculation methods, as well as aircraft noise caused by the number of persons affected;
1.4. the plane caused by the noise reduction measures taken off in adjacent land-use planning, noise insulation programs, operating procedures, including procedures for air navigation services, operating restrictions, including certain noise limits, evening and night flight restrictions, noise fees payments preferred runway use, special routes of the aircraft noise reduction.
2. "situation forecasting activities: 2.1. airport development programme, including information on capacity building and benefits that result from capacity building, runway or Terminal works, scheduled flight, and the anticipated increase in the number of flights;
2.2. Description of effect on noise climate without further measures will be taken to reduce noise levels, and the effectiveness of those measures;
2.3. Forecast noise contours, showing the number of persons affected by aircraft noise, as well as assessing the number of persons that already affect aircraft noise, and the number of persons affected by noise in the new residential area;
2.4. evaluation of the consequences and possible costs of not taking action to lessen the impact of increased noise-if it is to be expected.
3. evaluation of the application of additional measures: 3.1 all alternative measures for a reduction of the aircraft and the reasons for selecting to include complete information on the cost of introducing the measures, the number of persons who will benefit from the successful implementation of the measures, and the measure of the overall efficiency rating for a fixed period;
3.2. Overview of the effects of possible measures on the parties concerned and the protection of the environment in the field of competition;
3.3. selected additional grounds.
