DGCA counts an Indian flight on-time if it departs within 15 minutes of schedule, published monthly. Here is what that number measures, and what it hides.
Flight number, tail number and callsign look similar but name different things. Here is which one you have, and which search actually resolves it.
The Airbus A321XLR range explained: what changed inside the airframe, how far it actually flies now, and which routes that range band opens up.
Wind, visibility, cloud layers, temperature and altimeter: how to decode a METAR field by field, sourced to FAA and NWS aviation weather formats.
The jet stream is a fast, high-altitude river of wind that flows west to east. Here is why that makes eastbound flights quicker and westbound ones longer.
What a go-around is, why an unstabilized approach is the most common trigger, and what the manoeuvre looks like on a tracked flight path, with sources.
What is a red eye flight? The typical departure window, why airlines schedule them for aircraft utilisation, and why the seat is usually cheaper.
What an airport slot is, why only Level 3 airports need them, the 80/20 rule, and why a Heathrow slot pair can trade for millions between airlines.
What airplane mode actually switches off, why phones were restricted on older aircraft, and what the FAA and FCC have said about 5G and altimeters.
Great-circle distance is the shortest path on a sphere, not what a flight actually flies. What the number means, and why the real trip runs longer.
What are contrails, why some vanish in seconds and others spread into cloud, and how to tell one apart from a cirrus cloud, sourced to NASA.
Why are flight paths curved on a flat map when the plane is flying the shortest possible route? The great circle explained, with two real routes.
35,000 feet is not a rule, it is the middle of a range. How thrust, drag, weight and ATC's own altitude bands decide where a jet actually cruises.
Why airline schedules reset twice a year on two fixed Sundays, how the IATA summer winter schedule system lines up with DST, and what actually changes.
Leh airport flights season runs almost entirely before noon. The real reason is density altitude and afternoon mountain winds, not scheduling habit.
How TrackMyWings turns 4,225 cities with an airport in our dataset into pages, why most link back to one airport, and where the data comes from.
The 15 countries with the most airports in our dataset, why the count differs from Wikipedia's, and where the underlying airport data comes from.
Every airport below sea level in our dataset, from Bar Yehuda at minus 386 metres to Schiphol at minus 3, with the elevation and country for each one.
The ten northernmost airports in our directory by latitude, from Alert to Utqiagvik, with what each one is and why most are outposts, not destinations.
A high altitude airport takeoff needs more runway, explained through density altitude, with our own data on nine airports above 3,900 metres.
What is ADS-B? A plain-English guide to how a plane's own broadcast puts it on a map, how it differs from radar, and why some maps show gaps.
IATA vs ICAO airline codes explained: why Air India is AI on your ticket but AIC to air traffic control, and IndiGo is 6E but IGO on the flight plan.
What VT-, N- and G- actually mean on an aircraft's tail, why the US mark has no hyphen, and how to read a nationality prefix from any country.
A320neo and A321neo share a cabin width but not a length. Here's what the size difference actually changes about your seat, your legroom and your route.
The MAX 10 is the longest 737 MAX built, yet Boeing lists less range than the MAX 8. The engineering reason, sourced to Boeing and Simple Flying.
Airbus A350 vs Boeing 787 Dreamliner for the person in the seat: cabin altitude, humidity and typical seat width, sourced to Airbus and Boeing.
The A320 and A320neo look identical from the gate. The neo changes the engines, adds sharklets and cuts fuel burn: here is what is actually different.
What clear-air turbulence actually is, why it forms in jet-stream wind shear, and why onboard weather radar can't warn a pilot before it hits.
Why air traffic control puts a flight into a holding pattern, how the racetrack circuit works, and how long a plane can hold before it must divert.
How are flight numbers assigned? IATA hands out the airline code, the airline picks the digits, and 2026 schedules show the bands most carriers follow.
Folklore says eastbound flights get even numbers and westbound get odd. We checked nine published 2026 flight pairs to see where the rule holds.
Light, moderate, severe, extreme: the turbulence severity scale pilots use, quoted from the FAA's own table, plus what chop and continuous mean.
Minimum fuel vs MAYDAY fuel: how an airliner's fuel is stacked in layers, which layer is never spent, and the two calls a crew makes as it runs low.
Why do flights get diverted, who picks the alternate airport, and what the aircraft does after landing there: the operational sequence, step by step.
Why do planes dump fuel? Because most can take off heavier than they can land. The weight limit, the three options crews have, and where the fuel goes.
What a ground stop and a ground delay program are, why controllers hold flights on the ground, and who runs the same tools in India, Europe and Australia.
The aircraft is at the gate and you are ready to board, yet the flight is cancelled. How crew duty limits work, and why a timed-out crew grounds a flight.
What is ETOPS, and how does a jet with two engines fly hours from the nearest runway? The diversion-time rule, its numbers, and what it asks of airlines.
Airline network planning, step by step: demand, aircraft range, traffic rights, slots and the hub. What has to be true before a city pair gets a flight.
