This course is a continuation of the intensive overview of theory and flight-test techniques employed during the evaluation of helicopter performance characteristics. Emphasis is placed on turboshaft engine performance, climb and descent performance, takeoff and landing performance, and the performance characteristics of multi-engine helicopters. (Prerequisite: Successful completion of T&E 4111).
