Flight

This column will have as good an indication of the airline code and flight number as we can manage. For commercial airlines registered with IATA we may use either the 2-character IATA code or the three-letter ICAO code. We try to be consistent with what Geneva airport use in their airport display boards, web site and TV teletext. However, many movements are with aircraft which do not emit any registered call sign (often, they use their aircraft registration), so this field may be blank. It may also be blank for various other reasons!

Where the aircraft uses a proper 3-letter airline ICAO code, then there will usually be an entry in this column. However, some of the flights using such codes are completely unknown to us (such as many flights of NetJets), so there will be an entry with a query sign.

For flights for which we can be sure to know the full flight number, and of a registered airline operating to or from Geneva, we may sometimes have the flights in a list, or else know (by whether the actual number part is even or odd) whether the flight is to or from Geneva (a landing or a takeoff). Provided that this corresponds to the actual type of movement (landing or takeoff), then the colour code will be dark green or light green respectively. If there is a clash (mostly because of the pilot entering a wrong number, but sometimes an aircraft having had to turn around and return to Geneva) then the code will be red or purple.

Sometimes there are flights which transit via Geneva, or which might sometimes be arriving, sometimes departing (such as Ferry flights, to move an aircraft from one airport to another one: for these we use orange as a colour.

If we are sure about the flight code, but no idea whether it should be landing or taking off then we use yellow as the colour.

All very complicated, but virtually all scheduled flights should be green!
