    • (e) TCCA: Transport Canada, Civil Aviation.

3.0 Background

  • (1) Paragraph 602.96(2) of the Canadian Aviation Regulations (CAR) states in part; “Before taking off from, landing at or otherwise operating an aircraft at an aerodrome, the pilot-in-command of the aircraft shall be satisfied that … (b) the aerodrome is suitable for the intended operation”.
  • (2) The publication of TP312 5th edition changed the application concept of the “standards” affecting airport certification. This shift from the design based concept under the previous editions of TP312 to an operational concept in TP312 5th aligns the certification standards to the actual (or planned) operation at site by linking the standards to specific aircraft characteristics, aerodrome operating visibility condition, and level of service (Precision, Non-Precision, Non-Instrument). It also complements the document Criteria for the Development of Instrument Procedures -TP308 and other regulatory requirements currently stated in Parts VI, VII and VIII of the CARs.
  • (3) Following the coming into effect of TP312 5th, the CFS information for all certified airports was enhanced to include, amongst other items, the certification level of the obstacle free environment of the runways and taxiways based on the operational concept supporting the standards in TP312 5th.
  • (4) The publication of the Aircraft Group Number (AGN) provides aircraft operators much needed information to ascertain the suitability of the airport for their intended operation as mandated in the CARs. For airports certified to previous editions of TP312 the obstacle free area standards are based on the critical aircraft type linked to the certification requirements under CAR 302 at that time. Unless there are changes relating to the runway level of service, physical characteristics or change of critical aircraft, the largest scheduled passenger service aircraft currently operating at the airport is typically identified as the critical aircraft.
  • (5) However, the airports’ operating hours in respect of its certification is currently missing in the publications. This information is needed by air operators, notably those conducting scheduled passenger operations, to assess the certification status of the airport, as some elements forming part of airport certification requirements can only be effectively performed by having on site attendance of the airport operator. These include, but are not limited to, emergency response plan activation, safety management, runway condition reporting, issuance of NOTAMs, and direct reporting of hazards.
  • (6) Aerodromes are certified as airports based on the requirements stated in Part III, Subpart 2 of the CAR. CAR 302.01 states the following three individual situations whereby an aerodrome would be required to adhere to the certification requirements for ongoing operations:
    • (a) being within the built-up area of a city or town;
    • (b) receiving scheduled passenger service; or
    • (c) the Minister is of the opinion it would be in the public interest and it would further the safe operation of the airport.
  • (7) The majority of airports in Canada are certified on the basis of receiving a scheduled passenger service.
  • (8) Scheduled passenger service air operators are required by regulation to operate to/from a certified airport. It is therefore important for these air operators to know when the airport is meeting the requirements under Part III Subpart 2 of the CARs. The inclusion of the airports’ operating hours in the publication will complement current requirements in CAR 602.96(2)(b) and the scheduled air service requirements stated in CAR 703.15, 704.14, and 705.19.

    Division V — Operations at or in the Vicinity of an Aerodrome

    General

    602.96 (2)(b) the aerodrome is suitable for the intended operation;

    Scheduled Air Service Requirements

    703.15 (1) Subject to subsection (2), every air operator that operates a scheduled air service for the purpose of transporting persons shall operate the service between airports or heliports or between an airport or heliport and a military aerodrome.

    704.14 (1) Subject to subsection (2), every air operator that operates a scheduled air service for the purpose of transporting persons shall operate the service between airports or heliports or between an airport or heliport and a military aerodrome.

    705.19 (1) Subject to subsection (2), every air operator that operates a scheduled air service for the purpose of transporting persons shall operate the service between airports or heliports or between an airport or heliport and a military aerodrome.

  • (9) In order to meet the regulatory requirements of Parts III and VII, the aircraft characteristics of these air operations should be consistent with the airport’s certification level of service during the published operating hours and, as a minimum.
  • (10) It is recognized that aircraft larger, than the published certification level, such as cargo or charter are frequently part of the daily operational mix at an airport. When this occurs, those air operators are advised to contact the airport operator prior to the flight. This is needed so that the airport operator may establish procedures to ensure that the airport certification environment for the scheduled passenger operations is not compromised since this air operation must operate within a certified airport environment as stated in CAR 703.15, 704.14, and 705.19.

4.0 Aeronautical information publication enhancements

  • (1) The aeronautical publications will be enhanced to provide, in addition to the Aircraft Group Number, the airports operating hours, and Identification of Private Meteorological Services and operating hours (where applicable) commencing with the January 27, 2022 publication cycle.

4.1 Aircraft Group Number (AGN)

  • (1) The purpose of the AGN is to provide a simple method for interrelating the numerous technical specifications concerning the aerodrome and the characteristics of the critical aircraft for which the aerodrome, or part thereof is certified.
  • (2) The airport information in the CFS states the highest Aircraft Group Number (AGN) the runway obstacle free environment accommodates under its certification.
  • (3) The AGN is depicted as follows in the RWY DATA section of the CFS;

    RWY CERT - Rwy 16 RVR 1200(1/4sm)/Rwy 34 RVR 600 AGN IIIB

  • (4) The following table shows the breakdown of wingspans into AGN groupings. The wingspan and reference approach speed (VREF) are used in the determination of the AGN. The reference VREF to be used is at maximum landing weight with maximum landing flap, prior to any operational adjustments which would result in a higher VREF;
    Table 1-1: Runway Obstacle Free Environment
    Aircraft Group Number (AGN) Wing Span

    I (for VREF speed
    CAT C or D use AGN IIIB)

    Less than 14.94 m

    II (for VREF speed
    CAT C or D use AGN IIIB)

    14.94 m up to but not including 24.10 m

    IIIA (for VREF speed
    CAT C or D use AGN IIIB)

    24.10 m up to but not including 36.00 m

    IIIB (includes groups I - IIIA with C & D VREF speeds)

    24.10 m up to but not including 36.00 m

    IV

    36.00 m up to but not including 52.12 m

    V

    52.12 m up to but not including 65.23 m

    VI

    65.23 m up to but not including 79.86 m

    Note: Table 1-1 includes consideration of the higher approach speeds that occur in the runway environment.

    Example on use of the tables: An aircraft has a wingspan of 20 m and a reference landing speed (VREF) of 129 knots prior to any operational adjustments, such as for wind gusts. A standard references the use of Column II (wingspan) of Table 1-1 for its application. The aircraft falls into AGN II when referencing across the columns; however, the associated note directs the use of AGN IIIB due to the VREF being in the C category. For Table 1-2, the AGN is read directly across from the column referenced in the appropriate standard.

  • (5) For taxiways, the AGN is only published where the obstacle free environment is below (lower AGN) than that of the runway with the highest AGN. In such a case, the certification level will be published as follows in the RWY DATA section of the CFS;

    TWY CERT - Twy W AGN II

    Table 1-2: Taxiway Obstacle Free Environment
    Aircraft Group Number (AGN) Wing Span

    I

    Less than 14.94 m

    II

    14.94 m up to but not including 24.10 m

    IIIA / IIIB

    24.10 m up to but not including 36.00 m

    IV

    36.00 m up to but not including 52.12 m

    V

    52.12 m up to but not including 65.23 m

    VI

    65.23 m up to but not including 79.86 m

4.3 Identification of Private Meteorological Services

  • (1) NAV CANADA is entering into formal arrangements with operators of private meteorological services in support of instrument procedures. Formal arrangements between originators of aeronautical data and NAV CANADA will support an end-to-end data chain and data of the highest possible quality.
  • (2) The following reporting elements of private meteorological services will be published in the CFS Weather (WX) section to indicate an approved source of aeronautical data:
    • (a) “Altimeter”: Altimeter setting report observed from two aircraft altimeters. The private altimeter setting report is a weather service provided in support of an Approach UNICOM (AU). Contact the Aerodrome Operator (OPR) for further information on the specifics of the service.
    • (b) “Wind”: Human assessment of wind speed and direction. The private wind speed and direction report is a weather service provided in support of an Approach UNICOM (AU). Contact the Aerodrome (OPR) for further information on the specifics of the service.
