Answers. Best Answer: FL means Flight Level. It's used above 18.000ft (in the US, in other countries other altitudes are used as the boundary) to indicate the altitude in hundreds of feet. So FL230 is 23.000ft standard altitude.est Answer: FL means Flight Level.

The nostrils, which form the external entrance of the nose, lead into the two nasal cavities, which are separated from each other by the nasal septum, a partition formed of cartilage and bone. Three bony ridges project from the outer wall of each nasal cavity and partially divide the cavity into three air passages.
Actually, it is the turbinate swelling up and restricting the nasal passage which gives you that stopped up feeling. you have three turbinates in each side of your nose. They are like fingers. Their job is to moisten the air, and add some resistance to your nasal breathing. Coblation involves puncturing the lower of these with a coblater wand (small pointed instrument) it then destroys some of the tissue inside the turbinate creating a pocket that eventually collapses resulting in effectively a smaller turbinate.
