Fitness For Duty

Ensuring Personnel Are Safe, Capable and Ready to Operate

Fitness for Duty Is a Core Safety Requirement

A professional RPAS operation depends on people making good decisions.

That is only possible when the people involved in the operation are:

  • physically fit
  • mentally alert
  • free from impairment
  • capable of carrying out their duties safely

No person should perform a task related to the safety or navigation of a remotely piloted aircraft when they are unfit to do so safely. That principle sits at the heart of professional RPAS operations.

What Fitness for Duty Means

Being fit for duty means a person’s ability to perform their role safely is not impaired, and is not likely to be impaired.

For RPAS operations, that includes any condition that affects:

  • judgement
  • concentration
  • coordination
  • situational awareness
  • reaction time
  • decision-making

Fitness for duty is not limited to obvious impairment. It also includes more subtle issues that reduce a person’s ability to operate safely.

Common Reasons a Person May Be Unfit for Duty

Illness and Fatigue

Personnel may be unfit for duty if they are:

  • unwell
  • excessively tired
  • affected by illness
  • affected by injury

Fatigue, illness and physical discomfort can significantly reduce a person’s ability to:

  • assess risk
  • maintain concentration
  • respond to changes in the operating environment

Your current guidance identifies being unwell or excessively tired, and having an illness or injury that impairs safe performance, as clear examples of unfitness for duty.

Alcohol and Psychoactive Substances

Personnel are unfit for duty if they are affected by:

  • alcohol
  • illegal drugs
  • psychoactive substances
  • any substance that alters judgement or cognitive performance

These substances can impair:

  • reaction time
  • coordination
  • judgement
  • perception of risk

Your current Fitness for Duty page specifically identifies the consumption, use or absorption of psychoactive substances, including alcohol, as a factor that can impair safe duty performance.

Prescription and Over-the-Counter Medication

Personnel may also be unfit for duty if they are affected by medication.

This includes:

  • prescription medication
  • over-the-counter medication
  • medications that cause drowsiness, dizziness or slowed thinking

Examples specifically referenced in your current guidance include codeine and antihistamines. Even lawful medication can make a person unsafe to operate.

Reporting Unfit for Duty

Personnel must report any actual or potential unfitness for duty immediately.

That report should be made to the Chief Remote Pilot (CRP).

The CRP is responsible for taking the necessary action to:

  • remove the person from safety-related duties if required
  • reassign tasks where necessary
  • ensure the operation remains safe and compliant

Your current page makes it clear that personnel must immediately report potential or actual unfitness for duty to the CRP, who then takes action to remedy the situation.

Alcohol Consumption

Alcohol and RPAS operations do not mix.

Personnel involved in RPAS operations:

  • must not perform duties while under the influence of alcohol
  • must not consume alcohol within 8 hoursbefore commencing RPAS operations
  • must not consume alcohol at any time during an operation

Your current guidance states this clearly and uses the 8-hour rule as a baseline operational standard.

Drug and Alcohol Testing

RPAS operations conducted under a ReOC involve safety-sensitive aviation activities.

This means personnel may be subject to:

  • random drug and alcohol testing
  • testing required by CASA
  • testing required by a contracting organisation

Your current page notes that personnel working under the authority of the ReOC may be subject to random drug and alcohol testing and must comply with CASA and client testing requirements where they apply.

Fitness for Duty Is More Than Drugs and Alcohol

One of the most common misunderstandings is that fitness for duty only relates to alcohol or drug use.

It does not.

A person may be unfit for duty because of:

  • poor sleep
  • illness
  • emotional stress
  • medication
  • fatigue
  • distraction
  • reduced mental alertness

For a Chief Remote Pilot, this means fitness for duty must be treated as an operational risk issue, not just a disciplinary issue.

What a Professional Operator Should Have in Place

A professional operator should have:

  • a clear fitness for duty policy
  • procedures for reporting unfitness
  • a culture where people can step back from duties without pressure
  • CRP oversight of fitness-related risks
  • clear rules on alcohol, drugs and medication

This allows the organisation to manage impairment before it becomes an incident.

Fitness for Duty in the CRP Assessment Context

Candidates preparing for a Chief Remote Pilot assessment should be able to explain:

  • what unfit for duty means
  • common causes of impairment
  • the obligation to report unfitness
  • the CRP’s role in managing the issue
  • the 8-hour alcohol rule
  • the relevance of drug and alcohol testing to RPAS operations

This is a practical topic, not just a memory exercise.

Common Mistakes

We frequently see operators:

  • treating fatigue as a minor issue
  • assuming prescription medication is automatically acceptable
  • failing to report unfitness early
  • focusing only on alcohol and ignoring other impairments
  • allowing operational pressure to influence fitness decisions

These are all warning signs of weak safety culture.

A Simple Practical Test

Before any operation, personnel should ask:

  • Am I well enough to operate safely?
  • Am I tired, distracted or impaired?
  • Have I taken any medication that may affect performance?
  • Am I fit to make safe operational decisions?

If the answer is uncertain:

do not operate until the issue is resolved

How Uncrewed Approvals Can Help

Uncrewed Approvals provides practical resources to help operators and CRP candidates understand:

  • fitness for duty requirements
  • operational decision-making
  • CRP responsibilities under a ReOC
  • the practical safety standards expected in professional RPAS operations

This includes CRP preparation resources and study material designed to help candidates move beyond theory and apply these concepts in practice.

Frequently Asked Questions

What does “unfit for duty” mean?

It means a person’s ability to perform a safety-related duty is impaired, or likely to be impaired, by illness, fatigue, alcohol, drugs, medication or another factor.

Who should a person report to if they are unfit for duty?

The Chief Remote Pilot. Your current guidance makes the CRP the person who must be told immediately if unfitness for duty exists or may exist.

How long before operations must alcohol be avoided?

At least 8 hours before commencing RPAS operations, and not at all during operations.

Can legal medication still make someone unfit for duty?

Yes. Prescription and over-the-counter medications can affect alertness, coordination and judgement.

Safe Operations Start With Fit Personnel

Aircraft, procedures and approvals all matter.
But none of them can compensate for a person who is not fit to perform their role safely.

Fitness for duty is one of the simplest and most important safety controls in any RPAS operation
