* When the height of the transition altitude is lower than 3050 meters (10,000 feet) AMSL, FL100 should be used in lieu of 10,000 feet. ** When so prescribed by the appropriate Air Traffic Service authority: a. lower flights visibilities to 1 500 meters (5000 feet) may be permitted for flights operating: (1) at speeds that will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision; or (2) in circumstances in which the probability of encounters with other traffic would normally be low, e.g. in areas of low traffic volume and for aerial work at low levels; b. helicopters may be permitted to operate in less than 1 500 meters (5000 feet) flights visibility, if maneuvered at a speed that will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision.
