Drone Flight Logging Requirements Compared

Drone Flight Logging Requirements Compared

AIO Answer: Flight logging requirements vary across countries. Japan mandates three separate logs (flight record, daily inspection, maintenance) with 3-year retention. Australia requires 7-year retention under CASA rules. EU states (DE, FR, NL, SE) require logs under EASA for Specific category with 3-year retention. The UK requires logging per Operational Authorisation conditions. The US recommends but does not strictly mandate flight logs for Part 107, though they are essential for proving compliance. Canada and NZ require logs per their certificate conditions.

The Business Case for Flight Logging

Beyond regulatory compliance, flight logs protect your business. They prove due diligence in liability claims, track aircraft maintenance cycles, document crew experience hours, and provide evidence of safe operations for insurance renewals. Every serious commercial operator maintains comprehensive flight logs regardless of the minimum legal requirement.

Flight Log Requirements by Country

What to Log: Universal Best Practices

Pre-Flight Data

• Date and time of operation
• Location (coordinates or address)
• Aircraft identification (serial number, registration)
• Pilot name and credential number
• Weather conditions at launch (wind speed, visibility, temperature)
• Battery charge level at start
• Airspace authorization reference number

In-Flight Data

• Takeoff time
• Maximum altitude reached
• Flight duration
• Operational area boundaries
• Any anomalies or incidents
• Battery warnings or swaps
• Number of flights in the session

Post-Flight Data

• Landing time
• Battery charge level at landing
• Total flight time for the session
• Aircraft condition notes
• Any damage or issues observed
• Payload data summary
• Post-flight crew debrief notes

Country-Specific Logging Deep Dive

Japan — The Most Prescriptive System

Japan requires three separate log books under the Civil Aeronautics Act:

1. Flight Record Book (飛行記録): Date, pilot, aircraft, route, flight time, purpose, weather, and any incidents
2. Daily Inspection Record (日常点検記録): Pre-flight and post-flight inspection results for each day of operations
3. Maintenance Record (点検整備記録): All maintenance actions, parts replaced, and return-to-service confirmations

All three must be maintained for 3 years and produced upon request by MLIT inspectors. The prescribed format is detailed in MLIT guidance documents accessible through DIPS 2.0. Non-compliance can result in penalties up to JPY 500,000 or 1 year imprisonment.

Australia — The Longest Retention

CASA requires ReOC holders to retain flight records for 7 years — the longest among all 10 countries. This extended retention serves accident investigation purposes and allows CASA to conduct retrospective compliance audits. Records must include sufficient detail to reconstruct the circumstances of any flight. Digital records must be backed up and accessible throughout the retention period.

United States — The Voluntary Standard

Part 107 does not explicitly mandate flight logs, but Section 107.49 requires pilots to be able to demonstrate compliance with all operating rules. In practice, flight logs are the primary means of demonstrating compliance during FAA inquiries or enforcement actions. The burden of proof falls on the operator. Professional operators maintain detailed logs for liability protection, insurance requirements, and client reporting.

European Union (DE, FR, NL, SE)

EASA's framework distinguishes between Open and Specific category logging:

• Open category (A1/A3, A2): Operators should maintain records but the requirement is less formal
• Specific category (OA/SORA): Detailed logging is mandatory per the conditions of the Operational Authorisation, with 3-year retention across all EU member states

Germany's LBA can impose fines up to EUR 50,000 for inadequate record-keeping. France's DGAC can impose penalties up to EUR 75,000. Sweden uses criminal fines (dagsböter) scaled to income.

United Kingdom

Post-Brexit, the UK follows its own framework. Operators with an Operational Authorisation (GBP 524/year for PDRA01) must maintain logs as specified in their Operations Manual. The CAA can audit these records as part of OA renewal or spot checks. The retention period is specified in the OA conditions.

Digital Flight Logging Solutions

Modern flight logging increasingly uses digital platforms. Benefits include:

• Automatic data capture from drone telemetry
• GPS-stamped records that cannot be retroactively altered
• Cloud backup preventing data loss
• Instant retrieval for regulatory audits
• Integration with maintenance tracking and crew management

Important considerations for digital logging:

• Ensure your chosen platform stores data in a jurisdiction that meets your regulatory requirements
• Maintain backup copies — cloud service outages should not compromise your records
• Verify that digital timestamps are accurate and tamper-evident
• Some countries accept digital-only records; others may require the ability to produce paper copies on request

Flight Hours and Crew Currency

Flight logs serve a critical function in tracking pilot currency. While requirements vary:

• US: Part 107 requires recurrent knowledge testing every 24 months (free online), but no minimum flight hours
• UK: OA holders may have currency requirements in their Operations Manual
• AU: RePL holders must maintain currency per CASA standards
• CA: Advanced operations require recent flight experience
• EU states: Specific category OA holders follow their declared competency maintenance program

Maintenance Logging

Aircraft maintenance records are distinct from flight logs but equally important:

Frequently Asked Questions

Can I use a spreadsheet as my flight log?

Yes, most countries accept spreadsheets as a valid format for flight logging, provided they contain all required data fields and are maintained consistently. However, spreadsheets lack the tamper-evidence and automatic backup features of dedicated flight logging platforms. If using spreadsheets, implement version control and regular backups. Australia's 7-year retention requirement makes robust backup strategies essential.

What happens if I lose my flight logs?

Lost logs put you in a difficult position during regulatory audits or insurance claims. In the US, the burden of proof falls on the pilot — without logs, you cannot demonstrate Part 107 compliance. In Japan, failure to produce required logs when requested can result in penalties. In Australia, CASA considers inadequate record-keeping a compliance issue. Implement cloud backup and consider maintaining both digital and paper copies.

How detailed do flight logs need to be?

Detail requirements vary. Japan's prescribed format is the most detailed, requiring three separate log types. The US has the least prescriptive requirements. As a minimum best practice, record date, time, location, pilot, aircraft, flight duration, purpose, weather conditions, and any incidents. For Specific category operations in the EU and UK, follow the detail level specified in your Operations Manual or OA conditions.

Do I need to log training and practice flights?

Yes. Training and practice flights count toward total aircraft flight time (important for maintenance scheduling), pilot experience hours, and demonstrate competency maintenance. Some countries specifically require training flights to be logged. Even where not mandatory, logging all flights creates a comprehensive safety record.

Can authorities request my flight logs without notice?

In most countries, yes. MLIT inspectors in Japan can request flight logs during routine checks. CASA in Australia can audit records at any time. The FAA can request records during investigations. EU national authorities can inspect logs as part of OA oversight. The UK CAA can request records as part of ongoing surveillance. Keeping current, organized logs ensures you can respond to any request promptly.
