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

RiskMitigation
FlyawaySet RTH altitude; verify GPS lock; maintain VLOS
Battery failureCarry spare batteries; land at 30% charge; check battery health
Obstacle collisionSurvey area in person; set geofence; maintain visual awareness
Person entering areaUse cones/barriers; brief ground crew; have VO watch ground area
Manned aircraft conflictMonitor frequencies; maintain below 400 ft; yield immediately
Weather deteriorationSet conservative weather minimums; have indoor backup plan
Control link lossTest link before each flight; stay within range; have RTH set
Regulatory violationDouble-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:

  1. Debrief the crew — what went well? What could improve?
  2. Review flight data — battery usage, altitude exceedances, anomalies
  3. Inspect the aircraft — check for damage incurred during flight
  4. Log the flight — date, location, duration, purpose, conditions, notes
  5. Store equipment properly — batteries at storage voltage, clean and dry
  6. Report any incidents — within 10 days if reporting criteria are met
