  1. Flight is between KBWI and EDDF
  2. FDE is flight data entry?
  3. ETA is 0800Z?

Example from flight DE2075, Registration D-ABUC

Recorded August 14, 2022 00:51:31 UTC

Appears to be a takeoff report. Not sure if the message type is specifically for that purpose or is just a free-for-all free text message.

  1. EDDF is the destination airport

Examples (WG variant)

Appears to be another position report variant with wind data.

Example from flight WG0652, Registration C-FJVE

Recorded August 11, 2022 00:42:25 UTC

  1. GS is ground speed
  2. DEP is departure airport, CYUL in this example
  3. DES is destination airport, MUVR in this example
  4. ETA is estimated arrival time
  5. GW is gross weight? (unknown units)
  6. ALT is altitude in feet (33993 ft in this example)
  7. CAS is calibrated air speed (unknown units, possibly knots)
  8. SAT is static air temperature (probably in Celsius, -44.0 in this example)
  9. FN is flight number, ICAO format
  10. TFQ is total fuel quantity? Unknown units
  11. WD is wind direction (degree units, 276° in the presented example)
  12. WS is wind speed (not sure on units, possibly knots/hour)

Examples (F9 variant)

Appears to be a takeoff delay report message.

Example from flight F92286, Registration N392FR

Recorded July 20, 2022 11:15:27 UTC

FFT2286,KPHL,1049,    ,OVERNIGHT MX KEPT A/C OUT OF SVC. DIDNT GET PAPERWORK UNTIL 5 MIN PRIORTO PUSH TIME.
  1. KPHL is the departure airport
  2. 1049 seems to represent either OUT or OFF in UTC time

Example from flight F91171, Registration N318FR

Recorded August 17, 2022 17:35:25 UTC

  1. KPHL is the departure airport
  2. 1709 seems to represent either OUT or OFF in UTC time

Examples (MS variant)

Appears to be another position report variant without wind data

Example from flight MS0938, Registration SU-GEJ, ICAO 0101BA

Recorded July 21, 2022 02:24:42 UTC

N026.894/E046.406/UTC 020700/FOB 007.2/ALT 40000/CAS 0948/ETA 0403
  1. UTC field should represent the timestamp in UTC time but it's off by around 17 minutes. Since this message was from HFDL, the delay was from propagation issues?
  2. FOB is fuel on board, unknown units
  3. ALT is altitude in feet
  4. CAS is calibrated air speed, units unknown
