How to Use FlightRadar24 for Plane Spotting: Tips, Filters & Hidden Features
FlightRadar24 is the first app most plane spotters install — and many never go beyond tapping on a random aircraft to see its callsign. That's leaving a lot on the table. This guide covers the features and workflows that actually make a difference when you're out spotting.
What FlightRadar24 Does (and Doesn't Do)
What it does:
- Shows live ADS-B positions of most commercial and many general aviation aircraft
- Displays callsign, aircraft type, registration (usually), altitude, speed, and origin/destination
- Provides flight history (free tier: 24h; Silver: 90 days; Gold: 365 days)
- Allows filtering by aircraft type, airline, altitude, and squawk code
What it doesn't do:
- Identify aircraft from photos (that's what Aviation Spotter does)
- Show all military traffic (most military aircraft don't broadcast openly)
- Display unregistered or non-ADS-B aircraft
Understanding these limits means you'll know when to reach for a different tool.
Setting Up for a Spotting Session
Step 1: Set your home airport
In the app: Settings → My aircraft → set your local airport. This puts relevant arrivals front and center and enables push notifications for specific aircraft.
Step 2: Enable the arrivals layer
On the web version (flightradar24.com): click the layers icon → enable Arrivals/Departures trail. This draws the recent flight path of landing aircraft, making it easy to see which runway is active before you leave home.
The trick: Look at the trails converging on the runway threshold. That's where to position yourself.
Step 3: Check runway direction without reading METARs
Open FR24 at your target airport → look at the live traffic flow. All arriving aircraft will be tracking toward one end of the runway. The direction they're heading = the active landing direction. You don't need to check the METAR or NOTAM for basic runway selection.
The Filters That Actually Matter
FlightRadar24's filter system is underused by most spotters. Here's what's worth setting up:
Filter by aircraft type
Web: Click the filter icon (top right) → Aircraft Type → enter ICAO type code.
Useful ICAO type codes for spotters: | Code | Aircraft | |------|----------| | A388 | Airbus A380-800 | | A359 | Airbus A350-900 | | A35K | Airbus A350-1000 | | B789 | Boeing 787-9 Dreamliner | | B78X | Boeing 787-10 | | B744 | Boeing 747-400 | | B748 | Boeing 747-8 | | A124 | Antonov AN-124 (rare widebody cargo) | | C17 | Boeing C-17 Globemaster (military) | | P8 | Boeing P-8 Poseidon (maritime patrol) |
Use case: Set a filter for B744 + B748 at your airport to catch the remaining 747s before they retire. Every one of those flights is now noteworthy.
Filter by airline
Click the filter → Airline → enter ICAO airline code (e.g., BAW for British Airways, UAE for Emirates, DLH for Lufthansa).
Use case: If you know a specific airline is operating a rare livery or special paint scheme aircraft, filter to that airline and watch for its reg.
Filter by registration
Click a specific aircraft on the map → click "Track this aircraft". This shows you where it is now and where it's going — useful if you're tracking a specific tail number across its day.
Alternative: Search directly by registration in the search bar (e.g., type "G-BOAB").
Reading Squawk Codes
Squawk codes are 4-digit transponder codes that aircraft broadcast. Most of the time they're meaningless route codes assigned by ATC. But a few are significant:
| Squawk | Meaning | |--------|---------| | 7700 | General emergency — pilot has declared mayday | | 7600 | Radio failure — pilot can't communicate | | 7500 | Hijack — aircraft may be under unlawful interference | | 1200 | VFR (visual flight rules) — common in US GA aircraft | | 2000 | No squawk assigned — aircraft entering controlled airspace | | 0000 | Transponder malfunction |
In FR24 (web version), you can filter by squawk code to monitor for 7700/7600 codes in your area. This is not spotting in the traditional sense, but it's situationally useful.
Tracking Specific Aircraft
One of the most powerful features for serious spotters is tracking a specific registration across its career.
Finding interesting aircraft to track
SpottingClub.com and Planespotters.net list "rare" aircraft — unusual registrations, heritage liveries, or visiting aircraft at your airport. Cross-reference these with FR24's registration search to see if they're currently airborne.
Setting up alerts
FR24 Silver+ allows push alerts when a specific aircraft takes off or approaches your airport. This is the feature that makes dedicated spotters justify the £3/month subscription.
Workflow:
- Find an interesting aircraft on Planespotters.net (e.g., a 747 in a special livery)
- Note its registration (e.g.,
G-CIVB) - Search that registration in FR24
- Click "Set alert" → "Alert when this aircraft lands at [EGLL]"
- Receive notification 30 minutes before arrival → drive to spot
The FR24 + Aviation Spotter Workflow
FR24 tells you what's coming. Aviation Spotter tells you what's in your photo.
The gap between them is the moment when an aircraft is overhead, you're not sure if you read the tail number correctly, or you photographed something unusual and want to confirm the ID.
Combined workflow:
- Before the session: FR24 → identify what's arriving in the next 2 hours → note interesting registrations
- During the session: FR24 live → track approach timing → position correctly
- After the session: Upload photos to Aviation Spotter → AI reads the tail number from each photo → confirms the registration automatically → links to FR24 history
This collapses the post-session logging workflow. Instead of cross-referencing your photos with FR24 manually, you get the registration pulled from the image automatically.
Free vs. Silver vs. Gold: What You Actually Need
| Feature | Free | Silver (£2.99/mo) | Gold (£9.99/mo) | |---------|------|-------------------|-----------------| | Live tracking | ✅ | ✅ | ✅ | | Aircraft type | ✅ | ✅ | ✅ | | Registration | ✅ (most) | ✅ | ✅ | | Flight history | 24h | 90 days | 365 days | | Filters | Basic | Advanced | Advanced | | Aircraft alerts | ❌ | ✅ | ✅ | | Serial number & age | ❌ | ✅ | ✅ | | Aeronautical charts | ❌ | ❌ | ✅ |
Honest recommendation: The free tier is enough for casual spotting. Silver is worth it if you're tracking specific aircraft or want alerts. Gold is for aviation researchers and professionals — most spotters don't need 365-day history.
Three Things Most Spotters Don't Know FR24 Can Do
1. Replay past flights
On the web version: click any airport → "Playback" → set date and time. Watch the traffic flow from any past date. Useful for reviewing yesterday's session or checking what flew during an event you missed.
2. See aircraft the app hides
FR24 filters some military and government aircraft by default (contractual). ADS-B Exchange (adsbexchange.com) shows everything without filtering. If something suspicious is on your radar and you don't see it in FR24, check ADS-B Exchange.
3. Embed the live map
FR24 provides an embed code for the live map. If you're running a spotting community website or blog, you can embed the local airport's live map. It doesn't help your spotting directly, but it's useful for community tools.
Common Mistakes
Trusting FR24 as the definitive registration source. Some aircraft show an incorrect or outdated registration in FR24. Always verify with Planespotters.net or the FAA registry if precision matters.
Ignoring the trail layer. The trailing path shows you which aircraft just landed — useful for knowing what you missed in the last 15 minutes.
Not using FR24 before you go. The biggest mistake is arriving at the wrong end of the airport. Two minutes on FR24 before you drive eliminates this entirely.
