ASSESSMENT OF HANDLING QUALITIES OF LIGHT COMBAT AIRCRAFT (LCA-TEJAS) IN AIR-TO-AIR ATTACK MODE BY ANALYSIS OF HEAD-UP DISPLAY (HUD) VIDEO OF THE CHASE AIRCRAFT

Abstract

This Paper is intended to assess the handling quality of LCA-Tejas during air to air attack mission. In this paper handling quality of LCA in air-to-air attack mode is being assessed using image processing techniques. As a part of flight test program of LCA Tejas we have presented a methodology to assess the handling quality of LCA by detecting the target aircraft in every frame of the HUD video of the chase aircraft during an air-to-air attack mission. Based on the detection of the aircraft in every frame of the HUD video, percentage of time the aircraft is being targeted during a given test point is arrived at. This percentage is an indicator of the handling quality of the aircraft and is used to assess the ease with which the pilot can aim at the enemy aircraft while in close combat.
