Planning and Monitoring Enroute Fuel Requirements

INTRODUCTION

This Commercial and Business Aviation Advisory Circular (CBAAC) is intended to remind air operators of the requirements to plan and monitor enroute fuel requirements.

APPLICABILITY

All air operators operating under Subparts 705, 704 and 703 of the Canadian Aviation Regulations (CARs).

REFERENCES

Paragraph 705.25(1)(c) and Sections 704.20 and 703.20 of the CARs.

BACKGROUND

Recent inspections and audits have revealed that some air operators are not planning flights with sufficient fuel as required by Paragraph 705.25(1)(c) and Sections 704.20 and 703.20 of the CARs.

Changes to existing training programs and company operating procedures may be required to ensure flight crews and operational control personnel understand and comply with the CARs.

An air operator's flight planning system and training programs must be designed to ensure there is sufficient fuel planned and/or suitable aerodrome available as required in the event of a forced descent from flight planned altitudes due to an enroute emergency.

POLICY DEVELOPMENT

All flights must be planned and monitored to ensure adequate fuel quantities are available to meet the requirements as stated in the regulation.

Paragraph 705.25(1)(c) of the CARs prevents an air operators from authorizing a flight and a person from commencing a flight under Instrument Flight Rules (IFR) unless sufficient fuel is carried to allow the aircraft:

i. to descend at any point along the route to the lower of:

A. the one-engine-inoperative service ceiling, or

B. 10,000 feet Above Sea Level (ASL),

a. to cruise at the altitude referred to in subparagraph (i) to a suitable aerodrome,

b. to conduct an approach and a missed approach, and

c. to hold for 30 minutes at an altitude of 1,500 feet above the elevation of the aerodrome selected in accordance with subparagraph (ii).

Sections 704.20 and 703.20 of the CARs state that no air operator shall authorize a flight and no person shall commence a flight unless the aircraft carries sufficient fuel to meet the fuel requirements of Part VI and to allow the aircraft:

a. in the case of an aeroplane operated in IFR flight,

i. to descend at any point along the route to the lower of:

A. the single-engined service ceiling, or

B. 10,000 feet,

a. to cruise at the altitude referred to in subparagraph (i) to a suitable aerodrome,

b. to conduct an approach and a missed approach, and

c. to hold for 30 minutes at an altitude of 1,500 feet above the elevation of the aerodrome selected in accordance with subparagraph (ii); and

a. in the case of a helicopter operated in night VFR* flight, to fly to the destination aerodrome and then to fly for 30 minutes at normal cruising speed.

*VFR: Visual Flight Rules

ACTION

Air operators should review their flight planning systems and training programs to ensure all operational personnel are aware of and comply with the regulatory requirements of Sections 705.25, 704.20 and 703.20 of the CARs for the carriage of contingency fuel.

Flight planning systems must be designed to ensure sufficient fuel is carried to meet the requirement of the CARs or to avoid those areas where regulatory fuel requirements cannot be met. If the air operators' flight planning system does not address CARs fuel requirements with regard a descent to the altitudes and a suitable aerodrome as specified in the regulation, an air operator must take appropriate measures to comply with the regulation.

Similarly, training programs for flight crews and operational control personnel must address all enroute fuel and related alternate aerodrome issues applicable to the route structure, flight planning process and standard operating procedures used by their company.

FUTURE DISPOSITION

This CBAAC will remain in effect until further notice.

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. CBAACs are available electronically on the TC Web site, at: http://www.tc.gc.ca/eng/civilaviation/standards/commerce-circulars-menu-284.htm.
