Flight Zones and Airspace: Airspace Integration

Introduction

Understanding airspace integration is crucial for drone pilots operating within the European Union. With the growing use of unmanned aircraft systems (UAS), ensuring safe integration into controlled and uncontrolled airspace is a cornerstone of EASA regulations. As a drone pilot, you must know where you can fly, how to identify restricted areas, and how to coordinate with air traffic control (ATC) when necessary. This lesson will guide you through the essentials of airspace classes, UAS geographical zones, and tools to plan safe, compliant flights.

Whether you're conducting a professional operation or flying recreationally, mastering these concepts will keep your flights safe, legal, and efficient.

Understanding Airspace Classes

Airspace in the European Union is divided into several classes (A, B, C, D, E, F, G), each with specific rules governing the types of aircraft and operations permitted.

Key Airspace Classes Relevant to Drone Pilots:

• Class G (Uncontrolled Airspace):

  • Most drone operations occur in Class G airspace.
  • Pilots have full responsibility for avoiding other aircraft and obstacles.
  • No ATC coordination is required, but adherence to geographical zone restrictions is mandatory.

• Controlled Airspace (Classes C, D, E):

  • Controlled airspace requires coordination with ATC.
  • Operations in these zones typically require prior authorization, especially for drones operating beyond visual line of sight (BVLOS).
  • Example: Flying near an airport in Class D airspace requires clearance to ensure safety for both manned and unmanned aircraft.

Practical Example:

Imagine you're flying a drone near a major city. The area may include Class G airspace for general operations but also Class D airspace near the airport. You must ensure you stay outside the controlled airspace unless you have explicit permission from ATC.

UAS Geographical Zones

The European Union has established UAS Geographical Zones to regulate drone operations. These zones are defined by Member States and include areas where drone flights are:

• Allowed: No restrictions beyond standard operational rules.
• Restricted: Flights are limited or require special authorization.
• Prohibited: Drone operations are not permitted.

How Geographical Zones Are Defined:

• UAS geographical zones account for safety, security, privacy, and environmental concerns.
• Examples include:
  • Urban areas: Restricted to avoid risks to people and property.
  • National parks: Often prohibited to protect wildlife.
  • Critical infrastructure: Restricted or prohibited for security reasons (e.g., power plants, government buildings).

Where to Find Information:

• National aviation authorities publish UAS geographical zone maps.
• Use EASA-compliant tools like drone planning apps (discussed below) to check these zones before flying.

How to Check if an Area Is Restricted

Before each flight, it’s essential to confirm whether your intended flight zone has restrictions. Failure to do so can result in penalties or unsafe operations.

Steps to Check Restricted Areas:

1. Consult Official UAS Geographical Zone Maps:

   • Member States maintain official maps, often available online through aviation authority websites.
   • Example: France’s Geoportail platform provides detailed drone flight maps.

2. Use Drone Planning Apps:

   • Apps like DroneRadar, AirMap, or Drone Assist simplify checking restricted areas.
   • These tools integrate official data and provide real-time updates on airspace restrictions.

3. Read NOTAMs (Notice to Airmen):

   • NOTAMs include temporary airspace restrictions for events like airshows or emergency operations.
   • Accessible via national aviation authority websites or planning apps.

Using Drone Flight Planning Apps

Technology makes airspace integration easier for drone pilots. Several apps approved by EASA provide reliable tools for airspace checks, flight planning, and compliance verification.

Recommended Apps:

• AirMap:

  • Provides interactive maps showing controlled and restricted airspace.
  • Includes real-time updates on temporary restrictions.

• DroneRadar:

  • Popular in Eastern Europe, this app integrates local geographical zones.
  • Offers flight authorization requests directly through the app.

• Drone Assist:

  • Widely used in the UK, this app simplifies airspace checks for drone pilots.

Features to Look For:

• Geographical zone overlays.
• ATC contact information.
• Automated flight authorization requests (when applicable).

Practical Example:

Before flying in a new area, open a flight planning app and input your location. Check for restricted zones, temporary restrictions, or nearby controlled airspace. If restrictions exist, adjust your flight plan or request authorization.

Coordinating with Air Traffic Control

For operations in controlled airspace or near sensitive zones, you may need to coordinate with ATC.

When Is ATC Coordination Required?

• Flights in Classes C, D, or E airspace.
• Operations near airports, military zones, or critical infrastructure.
• BVLOS operations requiring airspace integration.

How to Coordinate with ATC:

1. Submit a Flight Plan:

   • Include details of your operation (location, altitude, duration).
   • Provide contact information for ATC communication.

2. Request Authorization:

   • Contact ATC directly via phone or email.
   • Follow procedures outlined by the relevant Member State.

3. Maintain Communication During Flight:

   • Monitor ATC instructions and respond promptly.
   • Example: ATC may issue instructions to adjust your altitude to avoid conflicts with manned aircraft.

Key Takeaways

• Airspace Classes: Know where you can fly without ATC coordination (e.g., Class G) and when authorization is required (e.g., Class C or D).
• UAS Geographical Zones: Always check for restrictions or prohibitions using official maps or apps.
• Restricted Areas: Use flight planning tools and NOTAMs to confirm whether an area is safe and legal for drone operations.
• Flight Planning Apps: Leverage tools like AirMap or DroneRadar for real-time airspace data and compliance checks.
• ATC Coordination: Essential for flights in controlled airspace or sensitive zones; always follow proper procedures.

By understanding airspace integration, you’ll ensure safe and compliant drone operations across the European Union. This foundational knowledge prepares you for more advanced topics, including BVLOS operations and risk assessments.
