1.0 Introduction
- This Advisory Circular (AC) is provided for information and guidance purposes. It describes an example of an acceptable means, but not the only means, of demonstrating compliance with regulations and standards. This AC on its own does not change, create, amend or permit deviations from regulatory requirements, nor does it establish minimum standards.
1.1 Purpose
- The purpose of this AC is to inform the aviation industry that air operators and private operators may now obtain a Canadian authorization by Special Authorization (SA) for take-off minima – with reported visibility below Runway Visual Range (RVR) 600 down to as low as RVR 300. This authorization will enable Canadian air operators and private operators to plan and execute taxi, take-off and return-to-gate operations with visibility as low as RVR 300 at approved airports, subject to the applicable requirements of the SA. The final step in the operational approval is the issuance of the SA to the air operator or private operator. This SA will also form the basis upon which a foreign National Aviation Authority (NAA) may authorize, within their jurisdiction, a Canadian air operator or private operator to conduct taxi and take-off operations in RVR 300 visibility conditions. It is important to note that authorization to conduct RVR 300 take-off operations automatically brings into effect credit for RVR 600 and RVR 1200 take-off authorization.
1.2 Applicability
-
This AC applies to Canadian air operators holding an Air Operator Certificate (AOC) issued under Part VII of the Canadian Aviation Regulations (CARs) and to private operators holding a Private Operator Registration Document (PORD) issued under Subpart 604 of the CARs, that wish to operate in as low as RVR 300 visibility conditions at approved airports. These will be commonly referred to as "operator" in this AC.
-
This document is also applicable to all Transport Canada Civil Aviation (TCCA) inspectors with surveillance duties, and to individuals and organizations that exercise privileges granted to them under an External Ministerial Delegation of Authority. This information is also provided to the aviation industry at large for educational purposes.
1.3 Description of Changes

3.0 Background
-
The Federal Aviation Administration (FAA) and the European Aviation Safety Agency (EASA) have authorized ground movements and take-off operations in visibilities of less than 600 ft (175 m) Runway Visual Range (RVR 600) down to RVR 300 (75 m) at approved airports for qualified crews with certified aircraft since the late 1990's. Transport Canada Publication (TP) 312, 5th Edition — Aerodrome Standards and Recommended Practices – Land Aerodromes contains certification information for an airport Low Visibility Operations Plan (LVOP) to as low as RVR 300. For the purposes of this Advisory Circular (AC), RVR 600 ft is considered equivalent to 175m; and RVR 300 ft is considered equivalent to 75m.
-
The FAA, the National Transportation Systems Center, United States Department of Transportation (VOLPE) and the National Aeronautics and Space Administration (NASA) conducted a low visibility operations study for operations below RVR 1200. This study was used to support an International Civil Aviation Organization (ICAO) OPS PANEL for harmonized low visibility operations. The ICAO OPS PANEL determined that pilots can operate visually to as low as RVR 500. Below RVR 500 Low Visibility/Surface Movement and Guidance Control System (SMGCS) plans are required for the safe movement of aircraft around an airport. The FAA/ ICAO has identified two levels of Low Visibility Operations (LVO)/ SMGCS: Level 1 RVR less than 1200 down to and including RVR 500 and Level 2 RVR less than 500 down to and including RVR 300. In order to conduct a take-off below RVR 500, a take-off guidance system is required.
-
Canadian airports that are approved for taxi and take-off operations in visibilities as low as RVR 300 have invested in lighting and other visual aids to meet the RVR 300 requirements of Transport Canada Publications (TP) 312, 5th Edition - Aerodrome Standards and Recommended Practices. Many Canadian air operators have invested in aircraft technology and crew training to enable LVO in conditions less than RVR 600.
4.0 Low-Visibility Operations – Aerodrome Limits and Take-Off Minima
4.1 General
-
RVR 300 operational authorization is required for taxi and take-off operations when the reported RVR is lower than RVR 600 and the airport LVO plan authorizes lower than RVR 600 taxi and take-off operations. Operational authorization for visibility as low as RVR 300 includes gate to runway and runway to gate aircraft taxi operations.
-
The Aerodrome Operating Visibility minima for LVO are usually classified by RVR and other factors (e.g., aircraft characteristics) while aerodrome limits are published in the Canada Flight Supplement using either RVR or visibility in statute miles, depending on the runway operation.
-
Take-off minima are published for aerodromes in the Canada Air Pilot (CAP). Where standard take-off minima are published, lower take-off limits as allowed by Special Authorizations (SA) may be available. This AC addresses criteria for take-off in low visibility conditions where additional requirements (operator and aircraft) must be met in order to ensure safe operations when using minima below the values acceptable for exclusive use of visual references.
-
Authorization for take-off minima below the level supported by use of visual reference alone (RVR 600) requires the use of a guidance system which has been demonstrated to provide an acceptable level of performance and satisfactory workload for the minima approved, with or without reference to visual cues. The performance and workload assessment of such a system needs to consider any compensation that may be introduced by the pilot for particular guidance system characteristics (e.g., coping with a slight localizer signal offset during initial runway alignment) or concurrent pilot use of the guidance system with limited or patchy visual references.
-
IMPORTANT: Taxi and takeoff operations at reported visibilities below RVR 600 down to and including RVR 300 may only be conducted at airports certified in accordance with TP 312 (5th Edition or later) or a foreign equivalent. The level of service information permitting RVR 300 operations must be published in the Canadian Flight Supplement under runway data or in NOTAM(s). SA for take-off operations below RVR 600 down to and including RVR 300 also requires that the operator and aircraft be certified as per the criteria and conditions listed in the applicable SA, which is being presented in this document's appendix.
4.2 Conditions for Special Authorization
- Appendix A provides the specific condition to be entered into the special authorization for these low visibility operations. The intent is to transcribe these conditions into the operator's AOC or Private Operator Registration Document (PORD). Section 4.3 provides guidance which is applicable to the specific conditions in Appendix A. Appendix B contains a compliance checklist that is intended to be used as a tool for both operators and the inspectors.
4.3 Specific Guidance
-
The following table contains specific guidance concerning the requirements for a special authorization for take-off operations in below RVR 600 conditions down to and including RVR 300. The guidance material listed below refers directly to the conditions provided in Appendix A.
Appendix A Condition Guidance 1.0 (2) (a) (ii) The moving map display should be used during taxi operations if the aircraft is so equipped. 1.0 (2) (b) Non-normal and emergency procedures should cover engine failure before or after V1, electrical failure, and low visibility take-off guidance alerts, warnings and failures. Non-normal and emergency procedures should also address possible scenarios during taxi operations. 1.0 (2) (c) Similar to RVR 600 operations. 1.0 (2) (d) (ii) This should include any special procedures in use at the airport such as one aircraft operating on the manoeuvring area at a time or the use of a "follow me" vehicle. 1.0 (5) If aircraft variants are applicable, training programs must take this into account in order to ensure that pilots are aware of any differences which exist and that they appropriately understand the consequences of those differences. 1.0 (6) Operationally relevant characteristics of the navigations systems which are to be used must be addressed in the operator's training program in order to promote safe operations. In the case of an Instrument Landing System (ILS), examples of information to cover would include beam bends, over flight disturbances, beam switchover to secondary transmitters or main and back-up power sources. 1.0 (6) (ii) A rejected take-off from a point prior to V1 shall include an engine failure. 1.0 (6) (c) (ii) (E) Although both pilots must be trained and qualified in order to conduct a take-off in conditions less than RVR 600 down to and including RVR 300, first officers may not be authorized to conduct the take-off (in control of the aircraft) due to company policy or limitations in equipment in the right seat. 1.0 (8) Normal and rejected take-offs shall be conducted in wind and runway surface conditions that become limiting during winter operations. There is no requirement to conduct a take-off and rejected take-off with a failure of the flight guidance device at a critical point if the flight guidance devices that are used demonstrate failure characteristics which are extremely improbable. 1.0 (8) (a) (i) The operator may elect to use airports that frequently experience low visibility conditions, complex airports on the operator's route system, airports with particular low visibility ground movement difficulties, or rarely used but significant contingency airports (e.g., Extended Range Operations with Two-Engine Airplanes (ETOPS) or Extended Range Operations (EROPS) diversion airports), as determined appropriate by the operator considering that operator's route system, aircraft types, training cycle, Line Oriented Flight Training (LOFT) scenarios used, and typical line issues being experienced. 1.0 (7) Training and checking in accordance with RVR 300 take-off authorization criteria automatically brings into effect credit for RVR 600 and RVR 1200 training and checking. 1.0 (10) Recency of experience requirements provides an assurance of the necessary level of proficiency for low visibility take-off operations. 1.0 (10) (c) Credit for a previous low visibility qualification in a different aircraft type or variant, or previous qualification in the same type or variant at an earlier time may be considered in determining the operator's type of program, length of program, required manoeuvres or repetition of manoeuvres for re-qualification for low visibility taxi and take-off operations. 1.0 (10) (d) A pilot that is authorized to operate in RVR 300 conditions that transitions to a similar aircraft type may be authorized these limits on the new aircraft upon completion of the required line indoctrination (providing he or she was qualified at these limits for at least 90 days prior to conversion). Similar aircraft shall be considered as turbo-propeller to turbo-propeller or turbo-jet to turbo-jet and in the same aircraft group number (AGN). 2.0 (2) Where non-magnetic source heading references are used (i.e. Inertial Reference Units), the source heading reference will utilize the current magnetic variation tables for the intended area of operation. 2.0 (4) With respect to maintenance of the take-off guidance system, emphasis is placed on maintaining and ensuring total system performance, accuracy, availability, reliability, and integrity for operations down to RVR 300. 2.0 (6) (a) Examples of resources that can be utilized in order to ensure program effectiveness include: manufacturer's recommended maintenance program information; and, reference information cited in this AC. Provision for low visibility operations may be addressed as a specific program or may be integrated with the general maintenance program. 2.0 (6) (a) (iii) Contractor or sub-contractor organizations and their personnel who are involved in the maintenance program must also be identified and recorded. 2.0 (6) (a) (iv) Examples of documents which specify relevant criteria include: valid type certificate (TC), appropriate supplemental type certificate (STC), records of compliance, assessment of status of any engineering orders, airworthiness directives, and service bulletins. 2.0 (6) (a) (vii) If any unique defect reporting procedures are applicable, such procedures shall be described in the operator's maintenance and operations documents. 2.0 (6) (a) (xiii) Appropriate systems ground and flight checks may need to be performed following heavy maintenance prior to return to service. 3.0 (1) The Canada Flight Supplement will list the aerodrome operating limits for each runway and taxiway. The level of service information permitting RVR 300 operations must be published in the Canadian Flight Supplement under runway data or in NOTAM(s).
