accordance with the provisions of appendix 1, section i, paragraph 5, to this annex;

B) The estimated time, meteorological conditions, number, direction and height above ground level of each pass over the calibration target appropriate to each sensor to be certified; and

O All necessary safety precautions that shall be observed during the in-flight examination of the observation aircraft and its sensors.

3 — Prior to and during the conduct of the in-flight examination, States Parties taking part in the certification shall have the right to visit the location of the calibration targets. The State Party conducting the certification shall provide such items of equipment as required to confirm that the calibration targets meet the specifications set forth in appendix 1, section i, to this annex.

4 — The in-flight examination shall be conducted during clear atmospheric daytime conditions, unless otherwise agreed, over the calibration targets appropriate to each category of sensor installed on me observation aircraft in! accordance with the provisions of appendix 1, section U, to this annex, to determine the ground resolution of each sensor.

5 — The State Party conducting the certification shall provide such data on the meteorological conditions at the location of the calibration targets during the in-flight examination of the sensors as are necessary to make the calculations in accordance with the methodologies specified in appendix 1, section in, to this annex.

6 — Each State Party shall have the right to designate personnel to take part in the in-flight examination. In the event that the number of individuals so designated exceeds the passenger capacity of the observation aircraft, the States Parties participating in the certification shall agree which of its personnel shall participate in the in-flight examination.

7 — Personnel of the States Parties designated pursuant to paragraph 6 of this section shall have the right to observe the operation of the sensors by personnel of the State Party conducting the certification.

8 — Personnel of the States Parties taking part in the certification shall have the right to monitor the unsealing of the film cassette and the storage, processing and handling of the original film negative exposed during the inflight examination, in accordance with the provisions of annex K, section ii, to the Treaty.

Section IV

Certification report

1 — Upon completion of the ground and in-flight examinations, data collected by sensors and from the calibration targets shall be examined jointly by the State Party conducting the certification and the States Parties taking part in the certification. These States Parties shall prepare a certification report which shall establish:

A) That the observation aircraft is of a type and model designated pursuant to article v of the Treaty,

B) That the sensors installed on the observation aircraft are of a category provided for in article jv, paragraph I, of the Treaty and satisfy the requirements of article rv, paragraph 2, of the Treaty;

c) That the technical information on sensors has been provided in accordance with annex B, section i, to the Treaty;

D) In the event that the ground resolution of a sensor is dependent upon height above ground level, the minimum height above ground level at which each such sensor on an observation aircraft of that type and model may be operated during an observation flight pursuant to the limitation on ground resolution specified in article iv, paragraph 2, of the Treaty;

E) In the event that the ground resolution is not dependent upon height above ground level, the ground resolution of each such sensor installed on an observation aircraft of that type and model, pursuant to the limitations on ground resolution specified in article iv, paragraph 2, of the Treaty; and

F) That the covers for sensor apertures or other devices that inhibit the operation of sensors are in accordance with the provisions of article iv, paragraph 4, of the Treaty.

2 — A copy of the information for each sensor provided pursuant to section i, paragraph 6, and section it, paragraphs 3 and 8, of this annex shall be attached to the certification report.

3 —Copies of the certification report shall be provided to all other States Parties by the State Party conducting the certification. States Parties that did not take part in the certification shall not have the right to reject the conclusions contained in the certification report.

4 — An observation aircraft and its associated set of sensors shall be deemed to be certified unless the States Parties taking part in the certification are unable to reach agreement on the contents of the certification report.

5 — In the event that the State Party conducting the certification and States Parties taking part in the certification are unable to reach agreement on the contents of the certification report, the observation aircraft shall not be used for observation flights until the issue is resolved.

APPENDIX I TO ANNEX D

Methodologies for the verification of the performance of sensors Installed on an observation aircraft

The ground resolution of each sensor installed on the observation aircraft, and, where its performance depends on height above ground level, the minimum height above ground level at which this sensor may be operated during an observation flight, shall be determined and confirmed on the basis of data collected over calibration targets appropriate to each category of sensor in accordance with the specifications in section i and calculated in accordance with the methodologies to be determined within the Open Skies Consultative Commission.

Section I Specifications for calibration targets

1 —Calibration targets shall be provided by the State Party conducting the certification in accordance with the provisions of annex D to the Treaty. Such calibration targets shall be used to establish the ground resolution of sensors, of a type appropriate to each sensor category, and designed in accordance with characteristics specified below.

2 — Calibration targets for establishing the ground resolution of optical cameras shall consist of a series of groups of alternating black and white bars. Each group of bars shall consist of a minimum of two black bars separated
