natural and simulated icing tests were conducted during february and march 1978 with a uh-1h helicopter equipped with an advanced ice protection system. this was the fourth program of icing tests accomplished with this test aircraft and the second to include natural icing. the objective of this year's program was to expand the icing test envelope, to gather additional data on ice protection system design and performance characteristics, and to obtain specific data for use in a product improvement program for the uh-1 partial ice protection system (kit a). the testing was conducted at ottawa, ontario, canada. seven tests in the spray rig and twelve natural icing flights were made totaling 25.8 hours of icing tests. icing was encountered on seven of the natural icing flights
