# Fatigue Management

> Manage crew fatigue with vACA FRMS duty limits, rest requirements, circadian rhythm guidelines, and countermeasures

# Fatigue Management

This section outlines the standards for managing crew fatigue and duty limitations at Virtual Air Canada Airline.

## Fatigue Risk Management System (FRMS)

Virtual Air Canada Airline's fatigue management is based on the Transport Canada Fatigue Risk Management System (FRMS), which is designed to:

* Scientifically monitor and manage fatigue-related safety risks
* Balance operational requirements with crew rest needs
* Provide a structured approach to identifying and mitigating fatigue hazards

## Maximum Duty Periods

| Crew Configuration | Maximum Scheduled Duty | Maximum With Extensions |
| ------------------ | ---------------------- | ----------------------- |
| 2-pilot crew       | 13 hours               | 14 hours                |
| 2-pilot augmented  | 16 hours               | 17 hours                |
| 3-pilot augmented  | 18 hours               | 19 hours                |

Note: Duty time begins at reporting time (typically 1 hour before departure) and ends 30 minutes after block-in.

## Minimum Rest Requirements

| Location                           | Minimum Rest Period                           |
| ---------------------------------- | --------------------------------------------- |
| Home base                          | 12 hours                                      |
| Away from base                     | 10 hours in suitable accommodation            |
| After crossing multiple time zones | 14 hours or local night, whichever is greater |

Rest periods must provide the opportunity for 8 hours of horizontal rest.

## Flight Time Limitations

| Period   | Maximum Flight Time                           |
| -------- | --------------------------------------------- |
| 24 hours | 8 hours (single pilot), 10 hours (two pilots) |
| 7 days   | 40 hours                                      |
| 28 days  | 120 hours                                     |
| 365 days | 1,000 hours                                   |

## Circadian Rhythm Considerations

* The Window of Circadian Low (WOCL) is defined as 0200-0559 home base time
* Duty periods that encroach on the WOCL may be subject to reduced maximum limits
* Additional rest may be required after multiple time zone transitions
* Flights scheduled during WOCL should utilize augmented crew when possible

## Fatigue Countermeasures

Approved fatigue countermeasures include:

1. **Strategic napping**:
   * Limited to 40 minutes during cruise
   * Only permitted with another crew member at the controls
   * Followed by 15-minute recovery period before resuming duties

2. **Controlled rest on flight deck**:
   * Only permitted on flights over 3 hours
   * Maximum 30 minutes per crew member
   * Only one pilot may rest at a time
   * PM may rest first, then PF if conditions permit

## Fatigue Reporting

Crew members experiencing fatigue that may compromise safety should:

1. Inform other crew members immediately
2. Consider appropriate mitigation strategies
3. Submit a fatigue report after the flight
4. Not operate another flight until adequately rested

Reports are reviewed to identify potential improvements to scheduling and rostering.

## Pilot Personal Responsibility

While the airline provides appropriate duty and rest schedules, pilots must:

* Arrive fit for duty
* Utilize rest periods for adequate sleep
* Manage sleep, diet, and exercise to optimize alertness
* Report for duty with at least 8 hours sleep opportunity in the previous 24 hours
* Not operate when their performance could be adversely affected by fatigue
