DJI Mavic 4 Pro Pre-Flight Checklist: The Complete Safety Guide
Two minutes of preparation can save you a $2,200 drone. Here is the checklist every Mavic 4 Pro pilot should run through before takeoff.
Why a Pre-Flight Checklist Matters
Pilots of manned aircraft use pre-flight checklists before every single flight — not because they have forgotten how to fly, but because human memory is unreliable under routine conditions. We skip steps. We assume. We get distracted. A checklist eliminates assumptions and catches the one thing you overlooked that could turn an expensive drone into expensive debris.
The DJI Mavic 4 Pro is a sophisticated machine with dozens of systems that all need to be working correctly for safe flight. Propellers, GPS, compass, obstacle sensors, gimbal, batteries, SD card, firmware, airspace — any one of these can cause a problem if neglected. The good news is that a thorough pre-flight check takes about two minutes.
Phase 1: At Home Before You Leave
Smart pre-flight starts before you arrive at the flying location. These checks save you from the frustration of driving somewhere only to discover you cannot fly.
Home Checklist
- Batteries charged — Drone battery, controller battery, and your phone. Charge the night before
- Firmware updated — Open DJI Fly app at home on WiFi. Update if needed. Never update in the field
- SD card — Verify it is inserted, formatted, and has sufficient space. Back up previous footage first
- Check weather — Wind speed under 25 mph (Mavic 4 Pro rated for level 5 wind resistance). No rain or thunderstorms
- Check airspace — Use B4UFLY, LAANC, or Aloft app to verify your planned location is clear. Get authorization if needed
- Gear packed — Drone, controller, ND filters, landing pad, spare propellers, charging cables
Phase 2: On-Site Physical Inspection
Once you are at your flying location, do a hands-on inspection before powering anything on. This takes about 60 seconds and catches physical issues that the software cannot detect.
Physical Inspection
- Propellers — Check all four for cracks, chips, or warping. Ensure they are securely attached and unfold freely
- Gimbal — Remove the gimbal cover/guard. Check for obstructions. The gimbal should move freely when gently nudged
- Camera lens — Clean with a microfiber cloth. Check for smudges, dust, or debris. Install ND filter if needed
- Battery — Seated firmly, no swelling or damage, contacts clean
- Obstacle sensors — Wipe all sensor windows (front, rear, sides, top, bottom). Dirty sensors cause false warnings or missed obstacles
- Arms and body — Unfold all arms, check for cracks or looseness at the hinges
- Landing area — Clear, flat surface. No sand, gravel, or debris that could be blown into the drone during takeoff
Phase 3: Power-On Software Checks
Power on the controller first, then the drone. Wait for them to connect and for the DJI Fly app to fully load before proceeding.
Software Checks
- GPS satellites — Wait for 12+ satellites before taking off. More satellites means more accurate positioning and safer RTH
- Compass status — Should show "Normal." If it shows a warning or requests calibration, calibrate before flying. Always calibrate when flying in a new location far from your last flight
- Return-to-Home altitude — Set this HIGHER than the tallest obstacle in your flying area plus a safety margin of at least 20 meters. This is critical
- Battery level — Drone should show at least 95% for a full session. Controller at least 50%
- Flight mode — Confirm you are in the correct flight mode (Normal for most situations)
- Camera settings — Verify resolution, frame rate, exposure mode, and color profile are set correctly for your shoot
- SD card recording — Take a test photo. Verify it saves to the card, not internal storage
- Obstacle avoidance — Verify sensors are active and not disabled. Set to "Bypass" or "Brake" depending on your environment
Phase 4: The Hover Test
Before flying away, do a low hover test. Take off and hover at about 3-5 feet (1-1.5 meters) for 10-15 seconds. During this hover, check for:
- Stable hover — The drone should hold position without drifting significantly
- Unusual sounds — Listen for grinding, rattling, or uneven motor sounds
- Gimbal operation — Tilt the camera up and down. Check for smooth movement and no vibration in the feed
- Controller response — Nudge each stick briefly. The drone should respond immediately and correctly
If everything looks and sounds normal, you are clear to fly. If anything seems off — land immediately and investigate. It is always better to troubleshoot on the ground than at 400 feet.
Post-Flight Checklist (Bonus)
A good pilot does not stop being careful after landing. A quick post-flight routine protects your gear and your footage:
- Inspect propellers for any new damage from the flight
- Clean the camera lens and sensors
- Replace the gimbal cover
- Review footage while context is fresh — note any issues
- Back up your SD card to a second location
- Charge batteries (do not store at 100% long-term — DJI recommends 40-60% for storage)
- Log your flight — location, duration, conditions, any issues. Useful for Part 107 compliance and maintenance tracking
