Night operations represent a frontier for advanced drone applications in Swedenโfrom emergency response to infrastructure inspection. However, regulatory frameworks are complex. Transportstyrelsen (Swedish Transport Agency) enforces EASA EU 2019/947 standards that mandate specific lighting, visibility requirements, and operational restrictions for nocturnal flights. This guide explains the complete regulatory landscape for night-time drone operations in 2026.
Legal Status of Night Drone Flying in Sweden
As of 2026, night flying is permitted but strictly regulated:
- Not an outright prohibition (unlike some European nations)
- Requires specific operational authorization for most commercial flights
- Recreational night flying is effectively prohibited (visibility requirements prevent it)
- Special permits available for emergency services and critical infrastructure
EASA Classification for Night Operations
EU 2019/947 defines night operations under:
Twilight Operations (Permitted Category)
- Flight during nautical dawn (30 minutes before sunrise) through nautical dusk (30 minutes after sunset)
- Enhanced anti-collision lighting required
- Remote pilot must maintain visual reference to terrain
- Reduced insurance premiums vs. full-night operations
- Approval timeline: 2-3 weeks
Full-Night Operations (Specific Category - SORA)
- Complete darkness (civil dusk to civil dawn)
- Mandatory Remote ID system with enhanced tracking
- Operator location monitoring (ยฑ100 meter accuracy)
- Autonomous collision avoidance systems required
- Approval timeline: 6-8 weeks
- Limited authorization (case-by-case basis)
Anti-Collision Lighting Requirements
Swedish regulations mandate specific lighting configurations for night flights:
Minimum Lighting Standards
- Red navigation light (port/left wing): Visible 2+ kilometers, 30-degree arc
- Green navigation light (starboard/right wing): Visible 2+ kilometers, 30-degree arc
- White strobe light (tail): Visible 2 kilometers, omni-directional, 40-60 flashes/minute
- Anti-collision beacon (fuselage): Additional rotating light for drones >7 kg
- Underbelly searchlight: Optional, but strongly recommended (increases visibility to aircraft)
Light Positioning
- Navigation lights must be mounted on wing tips (or at least 1.5 meters apart)
- Strobe positioned 0.5+ meters from other lights (prevent pilot disorientation)
- Anti-collision beacon mounted on vertical fuselage (maximizes visibility)
Testing Requirements
Before first night flight:
- Activate all lights on ground
- Verify brightness at 50-meter distance (minimum readable in 50% ambient light)
- Confirm 30-second light duration backup if power interrupted
- Document visual inspection in compliance log
Visibility and Visual Reference Requirements
Transportstyrelsen mandates strict visibility minimums for night operations:
Twilight Operations
- Minimum visibility: 5 kilometers
- Ceiling (cloud base): 500 feet above drone altitude
- Visual reference requirement: Remote pilot must maintain direct line-of-sight to aircraft
- No obstacles: Route must be clear of buildings, terrain within 100 meters (radar/vision system exception)
Full-Night Operations
- Minimum visibility: 10 kilometers
- Ceiling: 1,000 feet above drone altitude
- Visual reference requirement: Automated vision systems replace human visual contact
- Obstacle avoidance: Autonomous collision avoidance mandatory (LiDAR or equivalent)
- Real-time tracking: Continuous GPS monitoring with ยฑ5 meter accuracy
Authorization Process for Night Flying
Step 1: Operator Preparation (Weeks 1-2)
- Acquire advanced remote pilot certification (night operations endorsement)
- Install approved anti-collision lighting system
- Configure autonomous avoidance (if full-night operations)
- Prepare detailed risk assessment (SORA documentation)
Step 2: Transportstyrelsen Application (Week 3)
Submit:
- Lighting system technical specifications
- Drone specifications and Remote ID details
- Route maps with obstacle surveys
- Risk mitigation measures

- Issues conditional or full approval
Step 4: Test Flights (Week 7, if required)
- Conduct up to 10 supervised flights
- Document system performance and safety measures
- Operator must demonstrate proficiency
Step 5: Full Authorization (Week 8)
- Certificate issued, valid 12 months
- Annual renewal required with operational review
Remote Pilot Certification for Night Operations

Special Lighting Considerations for Swedish Operations
Winter Conditions (Darkness Duration Extremes)
Sweden's latitudinal position creates unique challenges:
- Northern Sweden (Kiruna): Complete darkness 24 hours (mid-December to mid-January)
- Southern Sweden (Malmรถ): 8-hour minimum darkness window (winter solstice)
- Stockholm region: 6 hours 30 minutes darkness minimum (December)
Aurora Borealis (Northern Lights) Operations
- Provides ambient light (but unpredictable)
- Cannot be relied upon for regulatory compliance
- Approval still requires full lighting systems
- Adds complexity to risk assessment (highly variable light conditions)
Equipment Approval and Testing
Approved Anti-Collision Lighting Manufacturers
- Helios Technologies: Swedish-engineered 1-5 kg systems
- Astrodyne/Sensortech: Industrial lighting solutions
- DJI Lighting Kit: Pre-certified for Class 1-2 drones
- Customized systems: Require individual EASA approval (8-12 week timeline)
Pre-Flight Verification Checklist
- [ ] All lights functional and brightness verified
- [ ] Navigation light arcs match specifications
- [ ] Strobe flash rate 40-60 fps confirmed
- [ ] Anti-collision beacon rotation verified
- [ ] Backup power tested (minimum 30-second duration)
- [ ] Light mounting secure (no vibration-induced flickering)

Operational Restrictions and Time Limits
Maximum Flight Duration
- Twilight operations: Duration limited by battery (no special time constraint)
- Full-night operations: Maximum 60-minute flight duration per authorization
- Multi-flight operations: 30-minute ground recharge required between flights
Weather and Environmental Restrictions
- Wind: Maximum 8 m/s (night operations more sensitive to turbulence)

Airspace Coordination
- Manned aircraft notice: Transportstyrelsen issues NOTAM 24 hours before operation
- Air traffic control coordination: Mandatory for routes near airports
- Military airspace: Requires Swedish Defense Material Administration approval
- Helicopter routes: Notification to emergency services (medical helicopters operate nights)
Common Night Operation Violations

FAQ: Night Flying Rules in Sweden
๐ฃ Q: Can I fly my drone at night for recreational purposes in Sweden? A: Practically not without authorization. Visibility requirements make amateur night flying nearly impossible. You'd need anti-collision lights, advanced certification, and specific approvalโwhich Transportstyrelsen rarely grants for recreational operations. ๐ฆ Q: What's the difference between twilight and full-night operations? A: Twilight (30 min before sunrise/after sunset) requires fewer systems and faster approval (2-3 weeks). Full-night requires autonomous collision avoidance and takes 6-8 weeks. Most commercial operations use twilight windows. ๐ฃ Q: Do I need to notify air traffic control before night flights? A: Yes. Transportstyrelsen issues a NOTAM (Notices to Airmen) 24 hours prior. You must also coordinate with local airports and emergency services if near medical helicopter routes. ๐ฆ Q: How much does night operations lighting cost? A: Basic systems (DJI-compatible): SEK 5,000-8,000. Industrial systems: SEK 15,000-30,000. Custom integration: SEK 30,000-60,000 plus EASA approval fees. ๐ฃ Q: Can I use thermal imaging instead of visible lighting for night operations? A: No. Regulations explicitly require visible anti-collision lights. Thermal imaging is optional supplementary system (increases safety but doesn't replace lighting).
