5.9 Flight Planning and Risk Mitigation
Key Takeaways
- Flight planning follows a systematic process: mission → location → weather → NOTAMs → authorization → equipment → briefing.
- Always check airspace, TFRs, NOTAMs, and weather before EVERY flight, even at familiar locations.
- Risk mitigation includes pre-planning for flyaways, battery failures, obstacles, and manned aircraft conflicts.
- Go/No-Go decisions should be made before arriving at the site — set criteria in advance.
- Post-flight review (debrief, inspection, logging) improves safety and performance over time.

5.9 Flight Planning and Risk Mitigation
Thorough flight planning is the foundation of safe drone operations. A systematic approach to planning reduces risk and ensures compliance with all applicable regulations.
Flight Planning Process
Step 1: Define the Mission
- What is the objective? (Photography, inspection, survey, etc.)
- What equipment is needed? (Camera type, sensors, payload)
- How long will the mission take?
- What are the deliverables?
Step 2: Research the Location
- Check airspace classification on a sectional chart
- Identify airports within 5 miles
- Check UAS Facility Maps for LAANC altitude limits
- Survey the area for obstacles (towers, power lines, buildings, trees)
- Identify landing and takeoff areas (flat, open, away from people)
- Determine ground risk — who or what is on the ground that could be affected?
Step 3: Check Weather
- Review METARs for current conditions at nearby airports
- Review TAFs for forecast conditions during your planned flight window
- Check radar for precipitation and thunderstorm activity
- Assess wind conditions — surface and aloft
- Determine if Part 107 minimums will be met (3 SM visibility, cloud clearance)
Step 4: Check NOTAMs and TFRs
- Search for active NOTAMs for the area (notams.aim.faa.gov)
- Check TFR website (tfr.faa.gov) for temporary restrictions
- Use B4UFLY app for quick confirmation
- Check for sporting events, VIP movement, or other TFR triggers
Step 5: Obtain Authorizations
- If in controlled airspace, obtain LAANC authorization or submit DroneZone request
- If operation requires a waiver, ensure the waiver is current and conditions are met
- Verify airspace authorization covers your planned altitude and area
Step 6: Equipment Preparation
- Charge all batteries (drone and controller)
- Update firmware if needed (never in the field)
- Check equipment — propellers, sensors, cameras, data storage
- Prepare backup equipment — extra batteries, spare propellers, backup controller
- Pack safety equipment — fire extinguisher, first aid kit, visibility vests
Step 7: Crew Briefing
- Brief all crew members on the PAVE assessment
- Assign roles and responsibilities
- Review emergency procedures
- Establish communication protocols
- Set go/no-go criteria
Risk Mitigation Strategies
| Risk | Mitigation |
|---|---|
| Flyaway | Set RTH altitude; verify GPS lock; maintain VLOS |
| Battery failure | Carry spare batteries; land at 30% charge; check battery health |
| Obstacle collision | Survey area in person; set geofence; maintain visual awareness |
| Person entering area | Use cones/barriers; brief ground crew; have VO watch ground area |
| Manned aircraft conflict | Monitor frequencies; maintain below 400 ft; yield immediately |
| Weather deterioration | Set conservative weather minimums; have indoor backup plan |
| Control link loss | Test link before each flight; stay within range; have RTH set |
| Regulatory violation | Double-check airspace, TFRs, NOTAMs; verify authorization |
Go/No-Go Decision Framework
Evaluate these categories before EVERY flight:
GO Conditions:
- ✅ Weather exceeds Part 107 minimums with comfortable margin
- ✅ No TFRs or NOTAMs restricting operations
- ✅ Airspace authorization obtained if needed
- ✅ Aircraft in perfect working condition
- ✅ Crew briefed and fit to fly (IMSAFE passed)
- ✅ Adequate batteries for mission plus reserve
NO-GO Conditions:
- ❌ Weather at or near Part 107 minimums
- ❌ Active TFR covering the operating area
- ❌ Unable to obtain required airspace authorization
- ❌ Any aircraft malfunction or damage found in preflight
- ❌ Any crew member fails IMSAFE assessment
- ❌ Insufficient battery supply for mission plus 20% reserve
Post-Flight Review
After every flight:
- Debrief the crew — what went well? What could improve?
- Review flight data — battery usage, altitude exceedances, anomalies
- Inspect the aircraft — check for damage incurred during flight
- Log the flight — date, location, duration, purpose, conditions, notes
- Store equipment properly — batteries at storage voltage, clean and dry
- Report any incidents — within 10 days if reporting criteria are met
