Telemetry—a Powerful Tool for Aircraft Flight Testing

Abstract

This paper describes the Evolution of the Flight Test Telemetry system with Real-time processing capabilities at the Design Bureau of HAL. In this paper is described the development of an Indigenous Telemetry System jointly by ISRO-HAL called “HIPFIT” standing for HAL and ISRO project on Flight Test Instrumentation Telemetry. A brief description is given of the various sub-systems. Their capabilities with applications of the Telemetry Systems to Aircraft Flight Testing and the Real Time processing capability is mentioned. Some grey areas of the Telemetry System are pointed out which commonly occur during the development phase of a project of this nature.
