EASA Endorsement Module: Beyond Visual Line of Sight (BVLOS) Operations

• Master the EASA regulatory framework and SORA risk assessment process specifically for BVLOS operations.
• Gain expert knowledge of Command and Control (C2) link technologies, performance, limitations, and procedures for maintaining robust links over extended distances, including datalink security.
• Understand and apply principles and procedures for Detect and Avoid (DAA) systems and/or alternative means to ensure separation from other air traffic.
• Develop proficiency in advanced airspace management, coordination with Air Navigation Service Providers (ANSPs), and contingency planning for BVLOS flights.
• Master advanced navigation techniques, including reliance on instruments and management of GNSS vulnerabilities for long-range missions.
• Develop comprehensive contingency and emergency procedures for complex BVLOS scenarios (e.g., lost C2 link, system failures far from pilot).
• Understand human factors and CRM principles pertinent to long-duration, remote, and potentially high-workload BVLOS operations.
• Successfully pass rigorous theoretical examinations and complex practical assessments simulating BVLOS conditions.

- Advanced EASA remote pilot qualification, such as EASA Remote Pilot Complete Training (RPCT) or a relevant STS certificate (e.g., STS-02 for certain BVLOS operations).
- Significant logged flight hours and extensive operational experience.
- Thorough understanding of UAS technology, aviation principles, and risk management (SORA).
- May require other specific endorsements or qualifications (e.g., Radio Telephony (RT) certificate).
- Proven ability to manage complex operational planning and execution.

This advanced endorsement module provides in-depth theoretical knowledge and demanding practical training essential for BVLOS operations. Key areas of study include:

Theoretical Knowledge:

• BVLOS Regulatory Framework: Detailed understanding of EASA Specific Category rules, Operational Authorisation processes for BVLOS, and SORA application for BVLOS.
• Advanced Airspace Management: Procedures for operating in various airspace classes BVLOS, Temporary Reserved Areas (TRA), coordination with ANSPs.
• Command, Control (C2) & Communications: In-depth theory of C2 link technology (frequencies, bandwidth, range, latency, redundancy), datalinks for payload, lost link protocols, and communication procedures. Cybersecurity considerations for C2 links.
• Detect and Avoid (DAA): Principles of DAA, types of DAA systems (technical and procedural), limitations, and integration into BVLOS operations. Alternative means of compliance.
• Advanced UAS Performance and Systems: In-depth understanding of aircraft endurance, energy management, system reliability, and failure modes relevant to long-range flights.
• Meteorology for BVLOS: Impact of en-route weather, micro-meteorology over extended areas, and use of advanced weather forecasting.
• Advanced Navigation for BVLOS: GNSS accuracy and integrity (RAIM), interference, spoofing, alternative navigation systems, and long-range flight planning tools.
• Human Factors in BVLOS: Workload management, automation complacency, decision-making in remote operations, crew coordination for extended missions.
• Comprehensive Contingency and Emergency Planning: Detailed procedures for all foreseeable failures in a BVLOS context (e.g., total C2 loss, engine failure far from base, airspace intrusion).

Practical Training (often including simulation and live flight under controlled conditions):

• Advanced mission planning and SORA-based risk assessment for complex BVLOS scenarios.
• Setup and operation of advanced Ground Control Stations (GCS).
• Management of C2 links, including handover and lost link drills.
• Practical application of DAA procedures (simulated or live with observers).
• Execution of simulated or actual BVLOS flights in controlled environments, focusing on navigation, system monitoring, and airspace awareness.
• Handling of complex in-flight emergencies and contingency procedures specific to BVLOS.
• Effective crew communication and coordination.

Extensive practical training, including advanced simulations and live flight exercises in carefully controlled environments, is central to this endorsement. Pilots will engage in:

• Detailed BVLOS mission planning using specialized software and SORA principles.
• Operating advanced GCS for long-range command, control, and telemetry monitoring.
• Managing C2 links, including performance monitoring and lost-link recovery drills.
• Implementing Detect and Avoid (DAA) strategies.
• Conducting navigation and flight maneuvers under simulated or actual BVLOS conditions.
• Responding to complex emergencies and system failures far from the recovery point.

Assessment for the BVLOS Operations Endorsement Module is rigorous and typically includes:

• An advanced theoretical knowledge examination covering all complex BVLOS-specific subjects.
• A comprehensive practical skills assessment, which may involve simulation and/or live flight exercises in a controlled environment, to demonstrate competency in planning and executing BVLOS operations safely and effectively according to EASA standards.

Successful completion of all assessments is mandatory to receive this advanced endorsement.

- Highly experienced EASA certified remote pilots (e.g., holding RPCT or relevant STS certificates) who are required to conduct UAS operations well beyond the pilot's direct line of sight.
- Professionals involved in long-range applications such as linear infrastructure inspection (pipelines, power lines), large-area mapping and surveying, environmental monitoring, long-endurance surveillance, or certain types of cargo delivery.
- UAS operators and organizations seeking to obtain Operational Authorisations for BVLOS flights within the EASA Specific Category.
