After his promotion to "Oberfähnrich" on 1 February 1934, Mölders began his pilot training at the "Deutsche Verkehrsfliegerschule" (German transport flying school) in Cottbus, lasting from 6 February 1934 to 31 December 1934. On 1 March 1934, he was promoted to "Leutnant" and assigned to the recently established Luftwaffe. In the early stages of his pilot training, he suffered continually from nausea and vomiting, but he eventually overcame these problems and finished the course at the top of his class. The next phase of his military pilot's training was from 1 January 1935 to 30 June 1935 at the combat flying school in Tutow and the "Jagdfliegerschule" (fighter pilot school) at Schleißheim near Munich. He received the newly created Pilot's Badge of the Luftwaffe on 21 May 1935.
