Every drone operator in New Zealand must be prepared to manage emergency situations. Understanding and practicing proper emergency procedures protects people on the ground, your aircraft, and your legal standing under CAA Part 101 and Part 102 regulations.
Types of Drone Emergencies
Communication Loss (Lost Link)
Lost link occurs when the drone loses signal connection to the controller or ground station.
Common causes:- Exceeding transmission range (typically 1-4km)
- Radio frequency interference
- Obstructions between drone and controller
- Low battery triggering failsafe
- Antenna misalignment
- Immediately alert ground personnel
- Attempt to regain signal by repositioning
- Activate Return-to-Home if enabled
- Clear airspace below drone descent path
- Monitor landing zone for safety hazards
- Document incident with timestamps
Motor or Propulsion Failure
Motor or propeller failure causes loss of flight control and uncontrolled descent.
Proper response:- Announce emergency to all personnel
- Clear area directly below aircraft
- Do NOT attempt recovery maneuvers
- Allow controlled descent
- Establish safety perimeter post-landing
- Inspect for damage before moving
- Document failure mode and conditions
Battery Failure
Battery failure can occur suddenly, causing immediate power loss.
Proper response:- Alert all personnel immediately
- Establish landing zone safety
- Activate emergency landing procedures
- Clear airspace for descent
- Avoid populated areas if possible
- Prevent re-entry after landing
- Assess battery condition for fire risk
GPS/Navigation System Failure
Loss of navigation data compromises altitude hold and position control.
Proper response:- Switch to manual flight control
- Reduce altitude carefully
- Reorient using visual references
- Return to known safe location
- Avoid complex maneuvers
- Land in clear, open area
- Document navigation system failure
CAA Part 101 Emergency Procedures
Operator Responsibilities
Under Part 101, operators must:
- Know emergency procedures before flying
- Brief all observers on emergency actions
- Maintain clear line of sight
- Have contingency for loss of link
- Keep landing zones clear
- Respond immediately to emergencies
Return-to-Home Configuration
Configure Return-to-Home safely:
- Set home point in clear, safe area
- Avoid return to populated spaces
- Test return procedure regularly
- Ensure adequate battery margin
- Set appropriate return altitude
- Verify GPS acquisition before flight
CAA Part 102 Emergency Procedures
Commercial Operations Requirements
Part 102 mandates comprehensive emergency planning:
- Written emergency response procedures
- Operator training and certification
- Regular emergency drills and tests
- Communication protocols documented
- Ground crew briefing procedures
- Incident reporting procedures
- Safety buffer zones established
Emergency Response Plan Components
Required documentation:- Potential emergency scenarios
- Response procedures for each scenario
- Personnel roles and responsibilities
- Communication protocols
- Medical emergency procedures
- Aircraft recovery procedures
- Incident notification procedures
- Post-incident analysis procedures
Communication Procedures
Ground Personnel Briefing
Before flight operations, brief all personnel on:
- Emergency signals and procedures
- Assembly point locations
- No-entry zones during emergency
- Communication protocols
- Medical contact information
- Incident reporting procedures
- Role assignments
Emergency Signals
Establish clear signals:
- Hand signals for lost link scenarios
- Radio calls for immediate hazards
- Alarm sounds for imminent danger
- All-clear signals after incidents
Incident Reporting
Document and report:
- CAA incident forms for accidents
- Insurance notification within timeframes
- Witness statements and contact info
- Photographic evidence of damage
- Complete timeline of events
- Preliminary root cause assessment
Post-Emergency Procedures
Immediate Post-Landing Actions
- Secure the aircraft - prevent unauthorized movement
- Check for hazards - fire risk, sharp debris, hot components
- Assess damage - photographic documentation
- Account for all personnel - ensure no injuries
- Establish perimeter - prevent unauthorized access
- Preserve evidence - don't move aircraft unnecessarily
Investigation and Documentation
- Photograph damage from multiple angles
- Interview all witnesses separately
- Record exact location and time
- Document environmental conditions
- Preserve flight data and logs
- Note any unusual sounds or behavior before incident
- Maintain records for CAA inspection
When to Report to CAA
Mandatory CAA notification:- Loss of control incidents
- Unintended crashes or losses
- Injury to any person
- Significant property damage
- Near-miss with manned aircraft
- Environmental hazards created
Prevention and Training
Pre-Flight Risk Assessment
Conduct risk assessment before every flight:
- Weather conditions safe?
- Airspace clear and unoccupied?
- Personnel briefed and positioned?
- Emergency procedures reviewed?
- Equipment functional and tested?
- Communication systems operational?
- Backup contingencies in place?
Regular Emergency Drills
Practice emergency procedures:
- Simulate lost link scenarios monthly
- Practice forced landing procedures
- Test Return-to-Home function regularly
- Conduct communication drills
- Review procedures with new operators
- Update procedures based on incidents
- Document all training and drills
Emergency Checklist
- โ Emergency procedures documented and known
- โ Ground personnel briefed on procedures

FAQ
๐ฃ What should I do if my drone loses signal during flight? Activate Return-to-Home if configured, or use manual control to return to a safe landing zone. Alert all ground personnel immediately and maintain visual contact if possible. ๐ฆ Who needs emergency procedure training? All operators and ground personnel involved in drone flights need emergency training. Part 102 commercial operations require formal documented training and competency assessment. ๐ฃ How do I prevent lost link emergencies? Maintain line of sight, verify signal strength before flight, stay within manufacturer-specified range, and avoid radio frequency interference sources. ๐ฆ What's the difference between Part 101 and Part 102 emergency requirements? Part 101 requires basic emergency knowledge. Part 102 requires comprehensive written procedures, formal training, documented drills, and incident investigation capabilities. ๐ฃ When must I report an incident to the CAA? Report any incident involving loss of control, unintended crashes, injury, significant property damage, or near-misses with manned aircraft. Contact CAA within 24 hours of serious incidents.
