Special Use Airspace

Understanding Restricted, Danger, Prohibited and Military Airspace for RPAS Operations

Special Use Airspace Introduces Additional Risk

Not all airspace is equal.

Within the standard airspace structure, certain areas are designated as Special Use Airspace (SUA).

These areas exist because:

  • hazardous activities may occur
  • military operations are conducted
  • access needs to be controlled for safety or security

For RPAS operators, Special Use Airspace requires deliberate planning, correct interpretation, and often approval before operating.

Types of Special Use Airspace

The four types of Special Use Airspace relevant to RPAS operations are:

  • Danger Areas
  • Restricted Areas
  • Military Operating Areas (MOA)
  • Prohibited Areas

Each has a different purpose and different requirements. Getting the category right is what determines whether – and how – you can operate.

Why This Matters for RPAS Operators

Operating in or near Special Use Airspace affects:

  • whether an operation can proceed
  • whether approval is required
  • what risks must be managed
  • how other airspace users may be operating

Misinterpreting Special Use Airspace is a common cause of unsafe or non-compliant operations.

Danger Areas

What Is a Danger Area?

A Danger Area is airspace within which activities dangerous to the flight of aircraft may exist at specified times.

Examples include:

  • live firing
  • parachuting
  • blasting
  • aerobatics and intensive flight training
  • other hazardous activity

Can RPAS Operate in a Danger Area?

Yes – in most cases, RPAS operations are permitted, and outside controlled airspace no clearance is required to enter.

However:

No separation service is provided, and hazards may be present.

What a CRP Must Do

Before operating in a Danger Area:

  • Identify the type of activity
  • Determine whether the area is active
  • Assess the level of risk
  • Apply appropriate controls

This may include:

  • avoiding active periods
  • adjusting location or altitude
  • coordinating with relevant parties

Entry may be allowed – but it must be a conscious decision.

Restricted Areas

What Is a Restricted Area?

A Restricted Area is airspace within which the flight of aircraft is restricted in accordance with specified conditions.

These are commonly used for:

  • defence activities
  • sensitive infrastructure
  • high-risk operations

Restricted Area Conditional Status

Every Restricted Area carries a conditional status code indicating its accessibility. In the first instance, these codes describe how crewed aircraft may flight-plan through the area and whether ATC clearance can be expected:

  • RA1 – pilots may flight-plan through the area and can normally expect a clearance
  • RA2 – pilots should not flight-plan through unless on nominated routes or by arrangement; a clearance is not assured
  • RA3 – pilots must not flight-plan through the area and a clearance will not be available

For RPAS operations, treat the RAx code as a guide to how accessible an area is likely to be – not as the approval mechanism itself. Approval to operate in a Restricted Area comes from the controlling authority regardless of the code.

Can RPAS Operate in a Restricted Area?

No – not without approval from the controlling authority.

Contact details for the controlling authority of a Restricted Area can be found in the SUA section of ERSA.

What a CRP Must Do

Before operating in a Restricted Area:

  • Identify the conditional status (RA1, RA2, RA3)
  • Determine if access is possible
  • Obtain approval from the controlling authority
  • Understand and comply with conditions

Restricted Areas should be treated as controlled environments.

Military Operating Areas (MOA)

What Is a MOA?

A Military Operating Area is a type of Special Use Airspace intended for military training and exercises conducted at specified times. It is its own category of SUA – not a type of Danger Area.

MOAs were introduced to replace military Restricted Areas, with the transition completed on 28 November 2024. In practical terms, a MOA behaves like a Restricted Area: it requires approval to enter.

Military activity in a MOA may involve:

  • fast jets
  • tactical manoeuvres
  • low-level operations

Can RPAS Operate in a MOA?

Generally:

Approval is required before operating in a MOA – request it from the administering authority listed in the AIP.

What a CRP Must Do

Before operating in a MOA:

  • Identify the administering authority
  • Obtain approval where required
  • Understand any conditions of operation
  • Confirm activation status

Contact and administering-authority details are typically found in:

  • the AIP
  • ERSA
  • airspace publications

Do not assume a MOA is inactive – confirm before operating.

Prohibited Areas

What Is a Prohibited Area?

A Prohibited Area is airspace within which the flight of aircraft is prohibited.

These are established over locations where flight cannot be permitted for security or safety reasons. At the time of writing this page, there were no Prohibited Areas in Australia, but that could change at any time.

Can RPAS Operate in a Prohibited Area?

No. Unlike a Restricted Area or a MOA, a Prohibited Area has no approval pathway – flight is not permitted.

What a CRP Must Do

  • Identify Prohibited Areas during planning
  • Keep the operation clear of them entirely
  • Do not rely on there being an approval process – there is none

Prohibited Areas are a hard boundary.

Is the Airspace Active? Activation, Hours and NOTAMs

Knowing the airspace type is not enough – you must know whether it is active.

Special Use Airspace is not always active. It may be:

  • permanently active
  • active during set hours
  • activated by NOTAM

Common activation indicators include:

  • HJ – daylight hours (sunrise to sunset)
  • HN – night hours (sunset to sunrise)
  • H24 – continuous
  • NOTAM – activated by NOTAM

Many SUA areas are activated or modified by NOTAM. This means a normally inactive area may become active, operating hours may change, or additional restrictions may apply. A NOTAM check is essential before every operation.

Confirming activation requires:

  • NOTAM review
  • ERSA reference
  • confirmation during planning

Where to Find Information

Information on Special Use Airspace is available from:

  • aviation charts
  • ERSA (En Route Supplement Australia)
  • the AIP
  • NOTAM briefings

A professional operator uses all of these together.

Operational Decision Making

When Special Use Airspace is present, the CRP must decide:

  • Can the operation proceed?
  • Is approval required?
  • Are risks acceptable?
  • What controls are needed?

If there is uncertainty:

Do not proceed until it is resolved.

Common Mistakes

We frequently see operators:

  • assuming Danger Areas are safe without checking activity
  • assuming that operations can never take place in SUA
  • treating a MOA as a Danger Area and skipping the required approval
  • not confirming whether the airspace is active
  • misunderstanding Restricted Area conditional status
  • overlooking Prohibited Areas during planning
  • failing to obtain required approvals
  • ignoring NOTAM activation

Special Use Airspace in CRP Assessment

CRP candidates should be able to:

  • identify Special Use Airspace on charts
  • explain the differences between types
  • determine whether approval is required
  • assess risk and apply controls
  • integrate NOTAM and ERSA information

This is commonly tested through scenario-based questions.

Practical Approach

A simple process:

  1. Identify Special Use Airspace on charts
  2. Check ERSA and the AIP for details
  3. Review NOTAMs for activation
  4. Determine approval requirements
  5. Assess risk
  6. Decide GO / NO GO

How Uncrewed Approvals Can Help

We support operators to:

  • interpret Special Use Airspace correctly
  • obtain approvals where required
  • integrate SUA into operational planning
  • prepare for CRP assessment scenarios

We help operators move from basic awareness to confident operational decision-making.

Treat Special Use Airspace With Respect

Special Use Airspace exists because there is:

  • increased risk
  • specialised activity
  • restricted access

A professional operator does not guess. They verify, assess, and decide.
