Flightradar24 guide: map, filters, details and playback for spotters

You’re standing at the fence, a dot appears on the horizon, and the question is always the same: what’s that coming in? For most spotters, Flightradar24 is the first place to look. The basics make sense within seconds, but the really useful tools sit one level deeper: filters with wildcards, the airport view, the info panel with its data source, and playback, which lets you go back through a missed morning after the fact. This guide walks you through the features step by step – from a spotter’s point of view, not a passenger’s.

Flightradar24 in one sentence

Flightradar24 is a flight tracking service based in Stockholm that merges position reports from a worldwide network of ground receivers, from multilateration (MLAT), satellite reception and other sources on a live map. You use it in the browser or with the app for iOS and Android. The basic version is free, and extra features come with the Silver, Gold and Business tiers.

An important point for understanding it: Flightradar24 doesn’t operate its own radar. Most positions are broadcast by the aircraft themselves via ADS-B, and volunteer receiving stations pick them up. How this works technically and where the limits are is explained in the fundamentals article Flight tracking with ADS-B for spotters. For using the service, all you need to know is this: what doesn’t transmit a signal or isn’t heard by any receiver is missing from the map.

Step 1: Reading the live map

When you open it, you land on the world map with countless yellow aircraft icons. Zoom in on your airport – the closer you zoom, the more icons the map shows, because it thins out when the view is wide. The icons rotate to match the direction of flight, so you see at a glance where an aircraft is headed.

According to the service’s support page, yellow is the default color for aircraft tracked in real time. An icon turns red in two cases: when you have selected the aircraft yourself and are following it, or when it is squawking an emergency code such as 7600 or 7700. You don’t read where a position comes from by the color, but in the info panel. The blue dots on the map, by the way, aren’t aircraft but airports. The details on symbols and color codes across different services are summarized in the article Flight tracker symbols and colors explained.

You customize the map in the settings menu:

• Map style: You choose between different map views. For a look at runways and taxiways, a view with aerial imagery is the clearest, if your version offers it.
• Labels: Instead of bare icons you can show labels, for example with flight number, callsign or registration. The range of label options can vary by subscription tier.
• Data sources: On the website you can show and hide individual sources such as ADS-B, MLAT or satellite. That’s useful if you want to see which aircraft in your area are only picked up via MLAT.
• Units: Altitude in feet or meters, speed in knots or km/h. As a spotter it pays to get used to feet and knots, because radio and METAR work with them too.

Step 2: Understanding the info panel

A tap on an icon opens the info panel – the heart of the app for spotters. In the basic version you’ll find, among other things:

Field	What it tells you	Spotter benefit
Flight number and callsign	Commercial number and radio callsign	Matching with the airport board and radio
Route	Departure and destination airport, departure and expected arrival time	Estimating when the aircraft will be at your spot
Aircraft type	Type name, often with ICAO type designator	Quick type identification before visual contact
Registration	Registration of the specific aircraft	Basis for your collection and logbook
Altitude and speed	Barometric altitude, ground speed	Telling whether the aircraft is already on final approach
Photo	Community photo of the aircraft or type	Livery check in advance
Data source	Where the position comes from (e.g. ADS-B, MLAT)	Judging how accurate the position is

With a Silver subscription, according to Flightradar24, you also get the aircraft’s serial number and age as well as climb rate and squawk; Gold adds extended Mode S data such as wind and temperature. For most spotter questions, though, the basic version is enough.

Two fields are often mixed up: flight number and callsign. The flight number is on your ticket, the callsign is what air traffic control hears – the two don’t have to be identical. Why that is, is explained in Callsign and flight number: the difference. The codes for airports and airlines are decoded in IATA and ICAO codes explained.

The info panel also takes you to the flight history of the registration: you see which routes exactly this aircraft has flown in recent days. That’s worth its weight in gold if you want to know whether a certain aircraft shows up at your airport regularly. How to approach this systematically is described in Tracking an aircraft by registration.

Step 3: Searching and setting bookmarks

The search bar accepts flight numbers, callsigns, registrations, airports and airlines. The most important one for spotters is the registration search: if you type in a registration, the map jumps to that aircraft if it is flying right now – otherwise you get its most recent history. The system behind registrations is explained in Understanding aircraft registrations.

With bookmarks you save flights, aircraft or airports that you look up again and again. Your home airport belongs there first.

Step 4: Filters that make the difference

At a big hub like Frankfurt Airport, the map is so full that interesting aircraft get lost in the crowd. This is where filters help. You reach them with the filter button at the bottom of the screen. There are two areas:

• Categories: Ready-made filters such as passenger, cargo, military and government or business jets. You can combine several of them by checking or unchecking them.
• Custom filters: On the tab for user-defined filters you choose between airline, aircraft, airport, route and advanced criteria. The app also lists filters by altitude and speed.

A particularly handy option is highlighting: instead of hiding all the aircraft that don’t match, the map shows them faded. That way you see your targets and still keep an overview of the rest of the traffic. On the website you toggle this with a button on the right edge of the map.

Filter ideas for spotters

Goal	Filter	What for
Heavies at your home airport	Airport plus type codes such as A388, B77W, A359	Spotting widebodies on approach early
Freighters	“Cargo” category	Night cargo and rare freighters such as the An-124
Military and government	“Military and Government” category	Transports, tankers, state flights – as far as visible
Visitors from abroad	Wildcards such as “G-”, “N” or “HB-*”	Foreign registrations at your home airport
A specific airline	Airline filter	Following new liveries and fleet additions

For military and government flights, keep in mind that commercial services hide some of these flights at the operators’ request. What is still visible and which services filter less is covered in Spotting government aircraft and in the Flight tracker app comparison.

Step 5: The airport view

When you tap an airport icon, the airport view opens with arrival and departure boards, flight status, aircraft on the ground, delay statistics and current weather conditions. For planning your day, this is the most important page:

• Arrivals board: Shows you which types are coming in the next few hours. Scroll through and mark the outliers – a rare airline, an unusual type, a charter chain.
• Aircraft on the ground: Helps you estimate what will depart soon, even if the flight doesn’t stand out on the departures board yet.
• Weather: Wind and visibility give you a hint about the runway direction in use. If you want to go deeper, read the raw data with Reading METAR and TAF.

Keep in mind that arrival times are only an estimate. Holding patterns, diversions or changed approach routes shift them. How reliable the values are is examined in How accurate are arrival times on flight tracker sites?, and how to spot holding patterns on the map is shown in Spotting holding patterns on the flight tracker.

Step 6: Playback – rewinding the airspace

Playback is the most underrated tool for spotters. It comes in two variants.

Playback of individual flights: Through search, the info panel or the airport boards you open the flight history and replay a past flight. You can review route, altitude profile and speed. That clarifies, for example, whether the aircraft you photographed really landed on the runway you suspect – or whether it flew a go-around.

Global Playback (website): Here you choose a date and time, start playback and see all the traffic in a map section. With the timeline you jump forward and back, and the speed ranges from 1x to 300x. Filters can be applied in playback too, as can map style, air traffic control boundaries and data sources.

How far back you can look depends on the tier, according to Flightradar24:

Tier	Flight history	Typical spotter benefit
Basic (free)	up to 7 days	Matching photos from your last outing
Silver	up to 90 days	Recognizing an aircraft’s patterns over weeks
Gold	up to 365 days	Seasonal comparisons, year in review
Business	up to 3 years	Long-term analysis

For your logbook, playback is ideal: you have a photo but no legible registration? Using the time from the image data and playback, you can usually find out which aircraft passed your spot at that moment. The complete process is described in Matching sightings with ADS-B logs.

Step 7: AR view and 3D view

Two features of the app seem playful at first, but are practical at the spot:

• AR view: You point your smartphone at the sky, and the app overlays through the camera which flights are in that direction. Ideal when a contrail runs high above you and you want to know what type it is.
• 3D view: Shows a flight with a 3D aircraft model, also from the pilot’s perspective. For spotting practice it’s more of an extra, but helpful for following an approach over familiar terrain.

The AR view depends on the accuracy of your phone’s compass and GPS. If it’s off, recalibrating the compass helps, and when several aircraft are close together you should double-check the match with the info panel.

Step 8: Alerts and subscription features

Custom alerts are tied to a subscription. With them you can be notified, for example, when a specific registration, an aircraft type or an airline is in the air; criteria can also be combined. You can also turn on an alert for the emergency codes 7600 and 7700 in the app. A detailed comparison of the alert systems of different services is in Flight tracking: setting up alerts.

Which subscription tier is worth it for whom is discussed in detail in Flightradar24 Silver, Gold and Business explained. The short version:

The feeder option is interesting for tinkerers: if you set up a receiver and feed data to Flightradar24, you get a Business account for as long as the station keeps transmitting. How to set it up is in Setting up fr24feed; which hardware you need is in Building your own ADS-B receiver.

Know the limits of the map

Flightradar24 is an excellent tool, but not a complete picture of the sky. Keep these points in mind:

• Coverage gaps: Over oceans, mountains or sparsely populated regions there are no ground stations. There the position jumps or is estimated.
• MLAT fuzziness: Aircraft without ADS-B are only shown if enough stations receive their signal to calculate the position. Close to the ground that often isn’t the case. Background is in MLAT and multilateration explained.
• Blocked flights: Some operators have their flights hidden or anonymized on commercial services.
• Delay: A few seconds pass between reception and display. At the spot that means: when the dot on the map is right at your location, the aircraft is usually already there.

If an aircraft is visibly in the sky but missing from the map, Why an aircraft doesn’t show up on Flightradar helps you find the cause. And if an emergency code shows up in the info panel or a flight gets a lot of attention because of an emergency, you can put it in context with Squawk 7500, 7600 and 7700.

Flightradar24 at the spot: a typical routine

Here is a proven routine for a day out, for example at the Munich Airport visitors’ hill (Besucherhügel) or the Zeppelinheim viewing platform:

1. The evening before: Go through the airport’s arrivals board, note anything special, check the wind.
2. Before you leave: Activate filters for the types you’re after, turn on highlighting.
3. At the spot: Set the map section on final approach, watch the order of the arriving aircraft.
4. After the session: Match photos using playback and registration history, and log them in your logbook.

Whether Flightradar24 or FlightAware suits you better is compared in detail in Flightradar24 vs. FlightAware.

Conclusion

Flightradar24 only gets really strong for spotters once you go beyond just tapping. The info panel delivers registration, type and data source, filters with wildcards and highlighting pull the interesting aircraft out of the crowd, the airport view structures your day, and playback turns every session into a verifiable archive. The free basic version covers most of this; a subscription is mainly worth it for alerts, aircraft age and a longer look-back. Always keep in mind that the map only shows what is received – looking at the sky remains irreplaceable.
