Singh almost faced a court-martial in February 1945 when he tried to raise the morale of a trainee pilot (later rumoured to be the future Air Chief Marshal Dilbagh Singh) by conducting a low level air pass over a house in Kerala. In his defence, he insisted that such tricks were needed for every cadet to be a fighter pilot. Later that year, he commanded the Indian Air Force Exhibition Flight. In February 1945, Singh was promoted to the rank of Wing Commander and in August, he was selected to attend the Staff course at the RAF Staff College, Bracknell in the United Kingdom. On his return, he commanded the Air Force Station Kohat and Air Force Station Risalpur.
