Preserving Data Integrity

To ensure the integrity of aeronautical information and data (AI/D) is maintained from origination to distribution, NAV CANADA is formalizing the provision of AI/D. Corrupt, erroneous, late or missing aeronautical information and data can lead to potential safety risks.

Overview of Mechanisms

The following mechanisms are part of the global transition to more dynamic, integrated, immediate and accessible data-centred Aeronautical Information Management (AIM):

  • Formal Arrangements: Aeronautical Information and Data concerning Private Meteorological Services
  • Aeronautical Data and Information other than Private Meteorological (MET) Services
  • Aircraft Movement Surface Condition Reports (AMSCR)
  • External Instrument Procedure Designs
  • Air Operator Designator and Call Sign Requests
  • Land Use Program
  • Level of Service Policy

Non-Private Meteorological Service AI/D

Direct all aeronautical data submissions and questions to NAV CANADA AIM Data Collection. 

Aircraft Movement Surface Condition Reports

NOTAM Entry System (NES)

Reporting authorities can upload Aircraft Movement Surface Condition Reports (AMSCR) directly to the NAV CANADA system using the NES web applicationOpen a new window.

This information is immediately available to customers on the Collaborative Flight Planning System (CFPS) and Aeronautical Fixed Telecommunications Network (AFTN) as an RSC NOTAM. Authorities with an automated reporting system can benefit from the direct web service that links their system directly with the NAV CANADA system.

AMSCR Materials

PDF AMSCR forms have been updated as of August 12, 2021 to reflect the new Runway Surface Condition (RSC) NOTAM format. These forms are now managed and provided by Transport Canada. For access to the new forms, please contact Transport Canada:

NOTAM Forms Frequently Asked Questions

These NOTAM forms have been introduced to help originators provide all the information necessary in the proper format to complete the NOTAM. It has been observed that information is sometimes missing and part of this is because the ICAO NOTAM format requires geographic location and height information, regardless of the NOTAM subject, to enable filtering and/or sorting of the information. The various formats in which NOTAM requests were received previously created the potential for errors to be introduced in the published NOTAM.

Coordinated universal time (UTC) is the time standard used around the world that all operations in aviation are done. As the originator is responsible for the information contained in the NOTAM, any associated times must be provided in UTC.

Previously, NOTAM requests were sometimes sent in local time which was conducive to errors in the published NOTAM. If the times are always provided in UTC, it is not necessary to know the time zone where the NOTAM is taking place.

The method to determine the UTC time from the NRC websiteOpen a new window is as follows:

  1. Identify your time zone
  2. Identify the time difference from UTC (in brackets)
  3. Add this to the local time

For example, if the time zone is EDT (UTC-04:00), four hours would need to be added to the NOTAM local time to determine the UTC time. If the local time is 1350 EDT then the UTC time would be 1750.

NOTE: The time difference from UTC will change for those areas that observe daylight savings time.

No, the new forms are not mandatory to use. However, they are highly recommended as they will help ensure all the necessary information is provided in the correct format by the originator when submitting a NOTAM request. Their use will also help prevent any unnecessary delays in issuing the NOTAM.

With the introduction of the ICAO NOTAM format, additional information is necessary to complete the NOTAM so that it can be filtered by various attributes, such as geographic location or altitude. This information is recorded in the NOTAM Q-Line which may or may not be visible in a NOTAM search. As a result, it is important that all sections of the NOTAM request form are completed to the greatest extent possible.

While the NOTAM Q-Line only requires coordinates to the nearest minute, coordinates to the nearest second are requested because the entry tool correctly plots and rounds coordinates consistently.

If the current process followed is to submit via a Flight Information Centre (FIC), a NOTAM request is submitted by telephone or by fax, unless otherwise specified by the FIC. The applicable FIC can be contacted by calling 1-866-WX-BRIEF (1-866-992-7433) to submit a NOTAM or obtain additional information.

The instructions on how to identify the NOTAM is on the request form. If there are any issues, the applicable FIC can be contacted.

No, the ticket number cannot be used to retrieve NOTAM information or to revise an existing NOTAM. The NOTAM number is required for these purposes.

The NOTAM text must be provided in both English and French when Québec FIC is the applicable FIC to be contacted unless the activity is occurring in Nunavut or Labrador.

If the form is being faxed and there is insufficient room to complete the NOTAM text on a single form, simply continue the NOTAM text on a second form. When faxing, clearly indicate that the NOTAM request is on multiple pages.

If issues are experienced accessing or downloading the form, please contact our Customer and Stakeholder Services team by email at service@navcanada.caOpen a new window or by telephone at 1-800-876-4693.

If the wrong form is submitted for the NOTAM request, please contact the applicable FIC immediately to advise of the error and ensure the information is published as desired.

External Instrument Procedure Designs

Aerodromes may access the services of contractors to conduct specific work related to instrument flight procedures. NAV CANADA collectively refers to instrument design contractors as External Design Organizations (EDOs). EDOs register with NAV CANADA and have submission requirements allowing NAV CANADA to review and publish their submitted designs to ensure accuracy and compliance to regulations and instrument procedure design criteria.
