An exercise begins on Wednesday next week, May 2, and runs until May 10.
During this time, the Eurofighter Typhoons guarding the skies over the capital during the games, which will be housed at the base in West End Road, South Ruislip, will carry out a series of training exercises.
Sea King helicopters will also make Northolt their home during the games, providing surveillance, and they are expected to perform a number of take-offs and landings during the exercise.
Work is also being carried out to modify parts of the perimeter fence. A section of hedge has been grubbed up because it was at risk of catching fire from the jet blast from the Typhoons.
It has been replaced with special fencing designed to dissipate engine blast and stop debris being blown at high speed across the ground.
Signs are being installed along the A40 Western Avenue where it runs along the base perimeter warning drivers of possible unusual noise.
But the goodwill of neighbours of the base has not been taken for granted, and the RAF is laying on the chance to get up close - or fairly close - to the Typhoons when the exercise is over.
On May 10, provided you have arranged the visit it advance, you may be able to come into the base and chat to some of the pilots and support crews and RAF staff will be able to answer questions about the base's role in the Olympic Air Security Plan.

Things will quieten down again after the exercise but pick up in the run-up to the Games, which start on July 27, and things will return to normal once the Paralympic Games end on September 9.
During the Games themselves, aircraft activity at RAF Northolt will drop right off. The normal commercial and military traffic will be reduced and the Typhoons will only fly if it is necessary. There may be some VIP traffic associated with the Games.
