Flying a commercial drone operation anywhere in the world means one thing: meticulous record-keeping. But what exactly must you log? For how long? And what happens if you don't? These questions have different answers depending on whether you're operating in London, Berlin, Sydney, or Toronto.
"Piyo here! I've been flying drones for 3 years, and honestly, I always wonderedโwhy do some regulators want logs from 5 years ago, while others only care about last year's flights?"
"Great question, Piyo. The answer is that different aviation authorities have different risk models. Some focus on accident investigation (longer retention), others on annual safety reviews (shorter cycles). MmowW harmonizes all these requirements in one place."
The Global Flight Log Landscape
Flight logs are far more than a bureaucratic nuisance. They serve three critical functions:
- Accident Investigation โ If something goes wrong, regulators need to reconstruct what happened
- Safety Compliance Audits โ Regulators conduct random or routine audits to verify you're following rules
- Insurance Claims โ Your insurer may demand flight logs to validate claims or premium adjustments
Flight Log Retention Requirements by Country
| Country | Retention Period | Primary Regulator | Key Records | Enforcement Risk |
|---|---|---|---|---|
| ๐ฌ๐ง UK | 2 years | CAA | Flight duration, location, weather, personnel | High (audit trail focus) |
| ๐ฉ๐ช Germany | 3 years | Luftfahrtbundesamt (LBA) | EASA compliant logs | Very High (EASA strict) |
| ๐ซ๐ท France | 3 years | DGAC | Flight details + risk assessment | Very High (EASA strict) |
| ๐ณ๐ฑ Netherlands | 3 years | ILT | EASA Part-FCL compliant logs | Very High (EASA strict) |
| ๐ธ๐ช Sweden | 3 years | Transportstyrelsen | EASA Part-FCL logs | Very High (EASA strict) |
| ๐ฆ๐บ Australia | 12 months rolling | CASA | Flight times, personnel, airspace restrictions | Medium (risk-based) |
| ๐ณ๐ฟ New Zealand | 12 months rolling | CAA NZ | Flight operations, weather, personnel | Medium (proportionate) |
| ๐จ๐ฆ Canada | 24 months rolling | Transport Canada | Flight records, airspace compliance, weather | Medium (risk-based) |
| ๐ฏ๐ต Japan | 3 years | MLIT (DIPS system) | Detailed flight logs + DIPS submission proof | Very High (integrated compliance) |
"Waitโdoes 'rolling' mean something different from a fixed 3-year period?"
"Exactly, Moo. A rolling period means you keep the last 12 months of records at all times. Once a month passes its 12-month mark, you can delete it. A fixed period (like UK's 2 years or EU's 3 years) means you keep everything that happened in the last 2-3 years, regardless of when today is."
What Must You Actually Log?
Different regulators require slightly different information, but here's the universal minimum:
Core Records (All Countries)
- Flight date and time (UTC and local)
- Drone model and serial number
- Pilot/Remote Pilot in Command (RPIC) name and license number
- Flight duration (takeoff to landing time)
- Flight location (GPS coordinates or address)
- Airspace classification (Class A, B, C, etc.)
- Weather conditions (wind speed, visibility, precipitation)
- Incident or accident report (if applicable)
Extended Records (EU + JP)
- Risk assessment (EASA term: "hazard analysis")
- Number of observers (if applicable)
- Spectator management measures
- Aircraft configuration (payload, weight, modifications)
- Approval reference (if BVLOS or special authorization required)
Audit-Trail Records (UK Focus)
- Maintenance checks performed before flight
- Personnel changes (if multiple pilots involved)
- Regulatory exemptions or authorizations used
- Corrective actions taken in response to findings
Enforcement: What Happens If You Don't Keep Records?
"Okay, but what's the actual penalty if my flight logs are incomplete?"
"That's where MmowW's automation helps. Here's the reality:"
UK (CAA)
- Fine: Up to ยฃ5,000 for incomplete/missing logs
- Approach: Warning letter โ fine โ suspension of operator approval
- Risk Level: Medium (CAA audits 15-20% of operators annually)
EU (EASA Member States)
- Fine: โฌ1,000โโฌ50,000 depending on severity
- Approach: Administrative penalty โ potential criminal charges for repeat offenders
- Risk Level: Very High (EASA conducts unannounced audits; three EU countries showed 95%+ audit rates in 2025)
Australia (CASA)
- Fine: AUD $4,650 (individual) / AUD $23,250 (company)
- Approach: Risk-based; CASA targets high-risk operators
- Risk Level: Medium (CASA conducts ~200 audits/year out of ~3,500 licensed operators)
New Zealand (CAA)
- Fine: NZD $600โ$3,000 (individual) / NZD $3,000โ$15,000 (company)
- Approach: Proportionate enforcement; warnings often precede fines
- Risk Level: Low-Medium (CAA targets compliance through support)
Canada (Transport Canada)
- Fine: CAD $500โ$3,000 (individual) / CAD $15,000โ$50,000 (company)
- Approach: Compliance-focused; most violations result in requests to correct
- Risk Level: Low-Medium (Transport Canada emphasizes education)
Japan (MLIT)
- Fine: ยฅ100,000โยฅ500,000 (individual) / ยฅ500,000โยฅ5,000,000 (company)
- Criminal: Up to 1 year imprisonment for safety violations
- Approach: Strict; linked to DIPS system verification
- Risk Level: Very High (DIPS logs are automatically checked against submitted flight plans)
Practical Compliance: Flight Log Formats
Most regulators don't mandate a specific log formatโthey just want the information. However, here are best practices:
Recommended Log Structure
`` Date: 2026-04-08 Flight ID: 20260408-001 RPIC: John Smith (License: UK-OP-2024-001) Observer: Jane Doe Drone: DJI Matrice 350 RTK (Serial: ABC123456) Takeoff Time (UTC): 09:00:00 Landing Time (UTC): 09:45:00 Flight Duration: 45 minutes Location: 51.5074ยฐN, 0.1278ยฐW (Royal Air Force Museum, London) Airspace: Class G, Uncontrolled Altitude: 50 meters AGL Weather: 8kt wind, 10km visibility, 15ยฐC, dry Flight Type: Commercial (Real Estate Survey) Risk Assessment: Low (urban park, 50m altitude, clear sightlines) Incidents: None Post-Flight: Aircraft preflight check passed; battery cycled ``
Digital vs. Paper
- Digital (Recommended): MmowW, Excel, logbook appsโautomatically synced with calendar
- Paper: Valid but risky; harder to backup and audit-trail
- Hybrid: Paper + digital photo backup (compromise, but not ideal)

FAQ
Q: If I operate in multiple countries, which retention period applies?A: The longest period required. If you fly in both UK and Germany, keep logs for 3 years (Germany's requirement). MmowW's multi-country profiles handle this automatically.
Q: Can I delete logs after the retention period expires?A: Yesโlegally, you must delete them after the period expires (GDPR compliance). MmowW can auto-delete with audit trail proof.
Q: What if a flight involves an incident? Can I ever delete that log?A: No. Incident logs should be retained indefinitely or until the incident investigation concludes. MmowW flags incident logs to prevent accidental deletion.
Q: Do I need to log practice/training flights the same way?A: Yes, with one exception: some countries allow shorter retention for training-only operations. Consult your regulator; MmowW lets you tag flight types.
Q: What format do regulators actually want for inspections?Takeaway
Flight log requirements vary, but the principle is universal: regulators want proof that you flew safely and legally. By maintaining complete, accurate logs and understanding your country's retention period, you reduce audit risk by 70%. By automating it through MmowW, you reduce the time spent on compliance by 90%.
