Use of Computer Programs to Monitor Flight Time and Flight Duty Time Limitations and Rest Periods

INTRODUCTION

Many air operators use computer software programs to assist in monitoring the flight time, flight duty time and rest periods of each of their flight crew members. This Commercial and Business Aviation Advisory Circular (CBAAC) is intended to advise air operators of a potential problem with some software programs.

APPLICABILITY

This CBAAC applies to all air operator certificate holders.

REFERENCES

Flight Time and Flight Duty Time Limitations and Rest Periods, Division II, of Part VII of the Canadian Aviation Regulations (CARs) - Subsections 700.14 through 700.23.

Standards for Flight Time and Flight Duty Time Limitations and Rest Periods, Division II, of Part VII of the Commercial Air Services Standards - Subsections 720.15 through 720.23.

BACKGROUND

The software that some air operators are using for flight time, flight duty time and rest period monitoring, does not ensure that the CAR requirements are being met. The software indicates that the proposed schedule complies with the CAR requirements, but this is not the case. There are no software programs of this type that have been sanctioned by Transport Canada.

For example, one program does not account for the requirement for 3 consecutive days free from duty in each 17 consecutive days period under all required circumstances (Section 700.19 of the CARs).

An air operator using such a program would believe that they were in compliance with the CARs, when in fact they were not. The responsibility for CAR compliance rests with the air operator, not with the software provider.

ACTION

Transport Canada recommends that air operators using software programs to monitor flight time, flight duty time and rest periods:

  • verify that the software program does provide the air operator with the correct information; or
  • ensure that the CAR requirements for flight time, flight duty time and rest periods are being complied with by another means.

FUTURE DISPOSITION

This CBAAC will remain in effect until the guidance material can be updated.

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
