  Note: I am taking a very simplistic view of aircraft range here for academic purposes. In reality, calculating the range is a complex problem because of the large number of variables involved. An aircraft's flight is not conducted at a single ground speed but varies from zero at take-off, to cruise conditions, and back to zero at landing. Extra fuel is expended in climbing to altitude and in maneuvering the aircraft. The weight is constantly changing as fuel is burned, so the lift, drag, and thrust and fuel consumption rate are also continually changing. On real aircraft, just like with our cars, there is usually a fuel reserve and the pilot makes sure to land the plane with fuel still on board, however we are going to neglect all of these effects for keeping our calculations simple R (Aircraft Range) = V (cruise speed) × T (Maximum time in air) [ Generally military aircraft cruise at a height of 30k feet with a speed of 0.8 to 0.85 mach, given that the speed of sound at 30k feet

Understanding the Tejas Program: Debunking Misconceptions and Explaining Shortcomings The Tejas program has often faced unfair criticism and unwarranted labeling as a failure without proper understanding of the project and the aircraft itself. While it is true that the Tejas program encountered challenges and has some shortcomings, it should not be considered a failure by any means. In this article, I aim to debunk some of the perceived problems and provide explanations for its genuine shortcomings.     Section 1: Long Development Cycle of the Tejas Program. One thing people often forget while discussing the Tejas program is that it was not solely focused on developing a fighter jet, it was much more than that and aimed at establishing a comprehensive aerospace ecosystem in India. The program oversaw the creation of the Aeronautical Development Agency (ADA) and the development of many critical subsystems such as the Multi-Mode Radar, Kaveri Engine, airframe alloys, flight con
