Why is the VT sign on aircraft in crosshairs

Noting that “it is a policy decision”, the Delhi High Court on Monday refused to entertain BJP leader Ashiwini Upadhyay’s — a serial litigator — petition that sought the removal of the call sign ‘VT’ written on all Indian aircraft, calling it a “symbol of slavery.” The court, asking him to approach the government, saying “it is for the government to do.”
What’s the problem: Terming it as a remnant of India’s colonial past, Upadhyay’s petition mentioned that “the prefix ‘VT’ stands for ‘Victorian Territory and Viceroy Territory’, which is the nationality code that each aircraft registered in India is required to carry.”
Is that right? Yes. Each country is assigned a unique call sign to identify the aircraft registered in its territory. For example, the US has been assigned the call sign ‘N’ while Russia’s is ‘RA’. India was assigned its call sign during the International Radiotelegraph Convention of Washington, in November 1927. Since India was then under British occupation as its colony, the British chose VT, which stood for Victorian / Viceroy Territory. The British in fact set the call sign of all their colonies starting with V.
