The sensors were not calibrated properly and timers for flow set. Writing a letter to the airport maintenance may get them adjusted, but chances are it will be ignored. Improper adjustment of these type of faucets is very common. Most installers hook them up and walk away. I find these things everywhere, nowadays, and as a plumber it makes me nuts.
The timing usually doesn't change for second and third uses on the water flow. What naturally happens when the flow runs a short cycle is a person will move their hands up, down, away and towards the faucet from the sensor. When moving in and out of the sensor range the faucet has a few seconds to reset and a moment delay before opening the solenoid and in that moment your hands have moved, so when the water comes on your hands are now not where they were and you get caught in a loop of 'tag' with the sensor until you walk away frustrated.
If a sensor faucet cycles for only a few seconds and shuts off, remove your hands completely from the sensor range. Count to three and put your hands back in the same place and wait for it to come back on. It takes a few seconds to reset once your hands are removed and placed back under. If it seems to stay off, the sensor is still picking up and object (hands) and will take a few seconds longer to reset. This is also a design to prevent vandalism by those who would clog a sink with paper towels or toilet paper and covering the sensor to flood the room.
