The Turboclair system basically consisted in jet engines used to warm the air around the runway and dissipate the fog. I understand a better visibility due to less fog allow less equipped aircraft to land safely, but such an artificial temperature elevation may create strong thermal and thus reduce the number of aircraft than can land safely (e.g. reduce to heavier aircrafts than may be less affected by turbulences).
(I imagine that nowadays, ILS is more effective than fog removal system in bringing an aircraft safely to the runway)
My question is: Because of probable turbulences due to this system, does it comes with additional restrictions compared to the same runway without fog?
