Altitude
Explore aircraft that the tracker can currently display, inspect available flight details and compare positions around a city. The map is a visual tool, not an airline departure board: aircraft markers alone cannot confirm a gate, check-in time, cancellation or passenger arrival at the terminal.
Use the city selector or map controls to move to an airport region. Zoom out to understand nearby traffic and zoom in for details. An empty area can mean a temporary data gap, not that no aircraft are flying there.
When available, read the aircraft identifier, timestamp, altitude, speed and route context together. A smooth moving marker may involve animation between reports; the displayed position is not guaranteed to be exact at the instant you view it.
Altitude labels can reflect barometric or geometric measurements and should not be treated as a flight-deck instrument. Ground speed includes the effect of wind and is different from the aircraft’s airspeed.
If you are collecting someone or catching a flight, open the operating airline’s official flight status and check the flight number, travel date, airports and local time. Aircraft position is useful context, not a replacement for the airline’s operational notice.
Coverage varies with receiver availability, altitude, terrain, region, network interruptions and data filtering. Search for the operating carrier’s callsign rather than a codeshare marketing number where appropriate. A missing position does not establish that the aircraft diverted or that an emergency occurred.
Data is offered for general aviation exploration only. Do not use this site for navigation, flight operations or safety-critical decisions. For a deeper explanation see the data-source limitations and flight number versus callsign guide.
Use this practical checklist whenever a marker seems to contradict an airline status page or another tracker. A map can visualize received observations, but it cannot establish when a passenger reaches the gate or exits the terminal.
Look at the operating airline on the ticket, then compare the aircraft callsign and the origin and destination airports. Codeshare numbers and operating flight identifiers can be different.
Compare the last received timestamp, not just the animated dot. For scale, an aircraft at 450 knots travels about 7.5 nautical miles per minute; old observations can appear far apart without either map proving a diversion.
A missing signal can reflect coverage gaps, altitude, terrain, network delays or filtering. It is not evidence on its own of a cancellation or emergency.
Use the operating airline or airport for arrival and terminal details. Allow for taxiing, immigration, baggage collection and the passenger reaching the agreed meeting point.
