It is claimed that the relatively favorable low-speed characteristics of helicopters, compared with fixed-wing aircraft, allow reduced visibility limits, without the need for additional equipment. Aspects related to instrument flight are considered and, based on the results of tests carried out elsewhere, a proposal for reduced visibility limits is formulated. Simulator tests should be carried out to substantiate the proposed limits of 100 ft decision height and 300 m runway visual range in a low-risk environment before carrying out flight tests.
