CAO 48.1 Plain English guide for fatigue management rules

Our plain English guide for fatigue management makes it easy to meet your obligations under Civil Aviation Order 48.1 Instrument 2019 and Subpart 137.Q of Civil Aviation Safety Regulations 1998.

This guide contains information about each appendix, with helpful hints explaining what’s expected of pilots and operators, and what might need to be considered when complying with the fatigue management rules.

Operators may choose to operate to the appendix (or in some cases the appendices) which is/are most appropriate for their operation. Prescriptive appendices range from those intended for simple operations to those intended for highly complex multi-crew operations where acclimatisation and crew augmentation are factors to be considered. A performance based FRMS appendix is also provided for those operators that wish to manage crew fatigue outside prescriptive limits.

The prescriptive appendices also address quite specific types of operation such as flight training, aerial work, medical transport and emergency services, ballooning, and aerial application (aeroplane).

Who will benefit from this guide

Pilots and operators will benefit from a shared understanding of the rules. By providing information in a simple easy to read form, CASA aims to facilitate this common understanding.
