Series: Learn Drones From Zero → Pro
By SpeedyDrone Canada

🧭 1. The DJI Fly Map: Your Drone’s GPS Lifeline

Every DJI Mini, Air, or Mavic drone uses GPS + GLONASS + Galileo to stay locked in place.
The DJI Fly map is your real-time dashboard.

🧩 Key Features of the Map:

• Live drone location

• Direction your drone is facing

• Home point location

• Satellite count

• No-fly zones (NFZ) in red

• Green zone = okay to fly

📱Tap the bottom-left corner of the camera view to switch to the map.
You can also expand the map full-screen.

🏡 2. Understanding Home Point (And Why It Matters)

Home Point = where your drone returns if:

• Signal is lost

• You press the RTH button

• Battery is low and auto-RTH triggers

✅ Home Point is usually set when the drone takes off
✅ A voice will say “Home point updated” — always listen for it
✅ Make sure your GPS has at least 10+ satellites before takeoff

Common Mistakes:

✈️ Pro tip: In the DJI Fly app, go to Settings → Safety → Update Home Point if you walk or move from where you launched.

🧭 3. Return-to-Home (RTH): Real Behavior Explained

When you trigger RTH (or the drone triggers it), here's what actually happens:

1. Ascend to preset height

   • Set in app (default is 30m)

   • Avoid trees/buildings in the path

2. Fly back in straight line to home point

3. Descend and land

🛑 RTH Mistakes to Avoid:

• Setting RTH height too low → drone may hit trees/buildings

• Forgetting to update home point if you move

• Panicking and pressing RTH when you’re nearby (fly manually instead)

✅ Best Practices:

• Set RTH height higher than tallest object nearby

• Watch for obstacles during return

• Take control manually if needed

• Know that DJI Mini 5 Pro, Air 3, etc. have Smart RTH with obstacle avoidance (if enabled)

⛔ 4. No-Fly Zones: What You Need to Know

DJI automatically locks out no-fly zones (NFZs) on your drone.

🟥 Hard NFZ (Red zone)

• Drone won’t arm or take off

• Includes airports, military zones, and secure sites

• Can only be unlocked with DJI FlySafe request

🟧 Warning Zones (Orange/Yellow)

• You can take off but get a warning

• Stay aware and follow local laws

🟩 Green Zones

• Clear to fly, but still your responsibility to stay safe

🧠 Your DJI Fly app checks these zones every time you connect — keep it updated.

🇨🇦 5. Canadian Airspace Basics (Simplified RPAS Rules)

If you're flying in Canada — here’s the short version for sub-250g drones like DJI Mini 4/5 Pro:

🟢 If your drone is under 250g:

✅ No license required
✅ No registration required
✅ Still follow safety rules:

• Don’t fly over people

• Stay under 400ft (122m)

• Keep drone in visual line of sight

• Stay away from airports, heliports, highways, and emergency zones

• Use common sense: don’t endanger anyone

🟡 If your drone is over 250g (e.g. Air 3, Mavic 3):

You must:

• Get a Drone Pilot Certificate (Basic or Advanced)

• Register the drone

• Follow NAV CANADA rules for controlled airspace

We’ll do a full post on this later — for now, if you're flying Mini drones, you're in the green zone (with responsibility).

✅ Summary: Know Where You’re Flying

GPS = powerful tool
RTH = smart but not perfect
Airspace = your job to check

👉 Always fly with intention
👉 Use DJI Fly app map
👉 Know your home point
👉 Don’t blindly press RTH
👉 Respect Canadian skies
