our industry lack vision or will to do so
let me give you a brief example. when the australian auto industry was shutting down local assembling, many associated industry like wiring loom manufacturers, car seat manufacturer, glass shield manufacturer started making the products tailored for aviation industry
same could be done here. your plane might not sell, but associated industries can make a huge cut in the global market. can't general tyre make tyres for small planes and become a global supplier ? Chemical industry can make aerospace sealants and adhesives. building a plane from scratch is a painstaking procedure, but we can start from associated items atleast. Indians and Chinese adopted the same path
regarding engines, yes any local industry may venture into small engines for drone application. its the same piston engine. they can start with the license production atleast
