  6. The service provider shall continue complying with all other requirements of paragraph 804.01(c) of the Canadian Aviation Regulations and Chapter 7 of the Manual of Surface Weather Observations not covered by this exemption.

VALIDITY

This exemption is in effect until the earliest of the following:

  1. Midnight EST November 1, 2003.
  2. the date on which an amendment to the appropriate provision of the Canadian Aviation Regulations and associated standards comes into effect;

ANNEX A

DEFINITIONS

In this Exemption,

"qualified person" means a person who meets the requirements of this exemption

"service provider" means any person providing aviation weather services pursuant to this exemption.

1. WIND DIRECTION AND SPEED OBSERVATIONS AND REPORTS

1.1 No person shall assess wind direction and speed in support of a straight in landing from an instrument procedure unless the aerodrome has a wind direction indicator that meets the requirements of subsection 301.06 of the Canadian Aviation Regulations.

1.2 The wind direction indicator pursuant to 1.1 shall have a functioning light source should the meteorological observation be made at night.

1.3 The wind direction and speed shall be specifically stated as "estimated" unless measured in accordance with paragraph 804.01 (c) of the Canadian Aviation Regulations and Chapter 7 of the Manual of Surface Weather Observations.

1.4 The service provider shall obtain authorization to report station wind direction and speed from the operator of the aerodrome or station, where the services are being provided, and shall notify the operator of the aerodrome or station of any change to the level of service being provided.

1.5 All meteorological reports of estimated wind direction and speed shall contain the following information:

  1. aerodrome or station name or location identifier;
  2. time of the meteorological observation, to the nearest minute;

  2. use of the Beaufort wind scale;
  3. use of any instrumental aids; and

(c) understands and has demonstrated, under practical conditions, how to estimate and report the wind direction and speed;
