Debrief your flight from its log.

The free online account of this analyzer, at flights.etep.com: your flights kept and searchable, your aircraft and their maintenance, your licences and recent experience, shared with your instructor or your club if you wish. You sign in with a code sent by e-mail. Free up to 1 GB of logs; logs encrypted and hosted in France.

No, unless you choose to keep it in your ETEP Flights account. Your browser reads the file on your computer and no byte of it is sent to ETEP or to anyone else. The base map, the terrain (3D view and profile under the altitude), the aerial imagery and the METARs are the only things loaded from the network, each only if you accept it: the OpenStreetMap server then sees the area displayed; the terrain service (Amazon), a rectangle around the flight rounded to half a degree; the aerial imagery you may choose (official orthophotos of France, Germany (by Land), Spain, the Netherlands, Austria, Luxembourg, Switzerland, the Northern Ireland coast and the United States, or Sentinel-2 imagery by EOX everywhere), the area displayed on the map and, in 3D, the same rectangle plus, in finer detail, a few kilometres around the recognised departure and arrival airfields (with "Full detail" ticked in 3D, the tiles around the aircraft, and so the area flown over); the METAR archive (Iowa State University), the codes of the airfields and the period of the flight; the satellite image of the day (NASA), the date and the area; the US radar (Iowa State University), the time to 5 minutes and the area — never your file or your track. If you accepted the site's audience measurement, it counts the functions used, never the file or its name.

The data logs of Garmin flight decks: G1000, G1000 NXi, G3000, Cirrus Perspective and G3X Touch (the .csv files of the data_log folder on the SD card: open the whole folder to see every flight at once). The files of JPI EDM engine monitors (.JPI: every flight of the file is listed); without a GPS, only the engine is shown. Dynon SkyView logs, Electronics International MVP-50 and CGR-30 flight files, GRT logs and the FLIGHT files of the Avidyne R9. ForeFlight track logs, Flightradar24 exports and ADS-B traces (readsb JSON), GPX or KML tracks with times, such as those exported by most navigation apps, and the IGC files of gliders, paragliders, hang gliders and microlights (for a soaring flight: launch, thermals with their climb, glides with their glide ratio). A track has no attitude, no airspeed and no engine data: the analyzer then works from the ground speed and the GPS altitude. Drones: ArduPilot logs (.bin, .tlog), PX4 logs (.ulg), DJI flight records (.txt; those written since 2021 are encrypted by DJI and cannot be read in the browser), Parrot flight files (PUD, GUTMA), Autel flight logs, and the CSV exports of drone log apps and services. Dynon, EI, GRT, Avidyne and ForeFlight files are read from their makers' documentation, Autel logs from open descriptions: if yours is not recognised, send it to us.

Put an SD card in the lower slot of the multifunction display before the flight. The G1000 writes one file per power-up in the data_log folder, named log_ followed by the date and time. Copy it to your computer and drop it here.

By default, below 500 ft above the field and down to 50 ft: a sink rate under 1,000 ft/min, airspeed within a 15 kt band, and bank under 15° below 300 ft; with a guided approach, the course and glidepath deviations under half scale. Every threshold can be changed under “Thresholds and rules”, to match your school's or your operator's procedures.

From the checks of the approach and the touchdown, each worth a number of points: the sink rate and the airspeed band on final, the bank, the course and glidepath deviations when the log has them, the sink rate and the load factor at the touchdown, and the touchdown zone once the runway is known. Points start to go at half of each limit, so keeping a margin pays, and are all gone at one and a half times the limit. An approach that was not stabilised is capped at 70, however good the touchdown. A go-around is never marked down, and a soaring trace or a track received on the ground (Flightradar24, ADS-B) gets no score: its touchdown is not precise enough. The score is an aid to the debrief, not an assessment of the pilot.

A light-aircraft log has no radio altimeter. The analyzer takes the elevation of the field from the log itself, from the altitude read while the aircraft rolls on it, and works heights from it. The altimeter reads a little low in ground effect: the moment of touchdown is taken from the load factor peak when the log has one.

From the OurAirports database (public domain): about 33,000 runways around the world. The runway whose centreline passes closest to the touchdown or the lift-off, in the direction flown, is the one used. When the database locates both ends of the runway, the analyzer measures the touchdown from the threshold, the height over the threshold and the runway left, and checks that the touchdown is in the first third of the runway. When it only knows the airfield and the heading of the runway, it names the runway without measuring. Your browser loads the database whole, so it tells us nothing of where you flew.

Send us a sample log through the link shown under the drop area: we add new formats as they come. It is the only case where a file leaves your computer, and only if you send it yourself. The files it reads today are listed in the answer above.

Yes. A helicopter is recognised from the rotor speed in its log or from a vertical lift-off, and you can also choose it in the settings. With the torque in the log, the analyzer tells a hover from the ground; without it, a hover in ground effect counts as on the ground. It then shows the hovers, the hover-taxi, the quick stops, the practice autorotations, the set-downs on a slope or off an airfield, and alerts of its own: fast descent at low speed (vortex ring), slow flight at low height (height-velocity diagram), fast descent or steep bank near the ground. Working definitions, to be agreed with your instructor.

Yes, once the page has been opened on this device: it keeps its own files (never yours) so that it opens at the airfield without a network. The base map, the terrain and the METARs still need the network.

Night: the sun more than 6° below the horizon where the aircraft is (civil twilight), as EASA and the FAA log it; the logbook export also counts the night landings in the sense of FAA 61.57 (from one hour after sunset to one hour before sunrise). Height above the terrain: the logged altitude minus a public elevation model with a grid of about 30 m. It is indicative and is no terrain awareness system.

Yes, in this browser only. They are not sent anywhere. “Restore the defaults” brings back the values above.
