The last Sunday night takeoff could have annoyed many people

The last takeoff last Sunday night, of a business jet at 23h28, could have annoyed many people for many reasons


On Sunday night, 8 August, the last takeoff of the evening, at 23h28, could have annoyed many people living around the airport, including ones in the Ferney-Voltaire region of France, for several reasons.

As the list of movements after 10pm shows, the last takeoff of the  night was a small Citation 525A business jet, with registration YR-TOY. Not being a regular scheduled flight, this was not shown on the Geneva airport web site list of departures. As such.the general public could not have known about it in advance.

The identification of the aircraft indicates that it is registered in Roumania as belonging to a company called Toyo Motor Group. Such an aircraft can carry up to 10 passengers.

The aircraft had flown into Geneva in the middle of that Sunday. It thus stayed in Geneva for several hours (perhaps just enough time to sample the pleasures of the Geneva August festival).

The official Swiss rules for takeoffs after 10pm state that the flights must be commercial ones. The definition of a commercial flight is one which is not restrictred o a small group of people and for which there is a monetary charge which exceeds the basic costs of the flight. In other words, it should be open to any group of people, who must pay enough money to make a profit for the flight operator. It is nice to know that there are members of the Roumanian population able to afford to come to Geneva for an afternoon in a small private jet!

The final reason that this flight would not have pleased people, particularly residents in the regions of St Genis and Ferney-Voltaire regions, would have been its flight path. Clearly, it needs to go to the east, but the takeoff direction that evening was to the south west (over Vernier). In order to turn towards its destination, the pilot did a U-turn to the right shortly after takeoff, thus going over Satigny, St Genis and Ferney-Voltaire. This trajectory is known by the name KONIL.

Why is this bad? Well, the communes in France which are under this KONIL trajectory have been complaining about the noise from its use for many years (and when I play golf in Bretigny I often understand why!). As a result, the KONIL trajectory has been banned for all particularly noisy aircraft and the Geneva Airport management has agreed that this trajectory will cease to be used after 10pm. It is dfficult to see how 22h28 can be classed as before 10pm!

In summary, a small Roumanian jet comes to Geneva for half a day and then leaves very late at night following a trajectory which should not normally be used after 10pm!

Enough reasons to ask for an explanation? I certainly think so, though I doubt that one would be forthcoming!
