Notice to Air Operators and Pilots Operating Under Instrument Flight Rules (IFR)


This Commercial & Business Aviation Advisory Circular (CBAAC) is intended to remind commercial air operators and private operators of the requirement to provide initial and recurrent instrument flight procedures training to pilots.


  1. Section 602.104 of the Canadian Aviation Regulations (CARs) - Reporting Procedures for IFR Aircraft When Approaching or Landing at an Uncontrolled Aerodrome.
  2. Section 602.101 of the CARs - Mandatory Frequency  (MF) Reporting Procedures on Arrival.
  3. Sections 723.98, 724.115 and 725.124 of the Commercial Air Service Standards (CASS) - Training Programs.
  4. Aeronautical Information Publication (A.I.P. Canada) RAC 9.11 through 9.14.


A recent increase in the number of incidents and regulatory infractions has highlighted a need for aircrews to review IFR reporting procedures at uncontrolled aerodromes. Possibly a lack of knowledge or pilot inattention are the principal causes of non adherence to established procedures. The frequency of occurences suggests that this type of operation may not be sufficiently covered in initial and recurrent training.

An air operator seeking authorisation for flights in Instrument Meteorological Conditions (IMC) is required under the CASS to provide annual training in instrument flight procedures to include departure, enroute, holding and arrival. A.I.P. Canada RAC 9.11 through 9.14 provide reference material for discussion on uncontrolled aerodrome procedures.


Transport Canada believes that when operators dispatch flights, they must ensure that the pilots are knowledgeable and competent to perform their assigned duties. Where applicable, operators are to verify that arrival procedures at uncontrolled airports are included in their flight crew training program.

Commercial & Business Aviation Advisory Circulars (CBAAC) are intended to provide information and guidance regarding operational matters. A CBAAC may describe an acceptable, but not the only, means of demonstrating compliance with existing regulations. CBAACs in and of themselves do not change, create any additional, authorize changes in, or permit deviations from regulatory requirements.
