Flight lieutenant

Flight lieutenant (Flt Lt or F/L) is a junior officer rank used by some air forces, with origins from the Royal Air Force.[1] The rank originated in the Royal Naval Air Service (RNAS) in 1914. It fell into abeyance when the RNAS merged with the Royal Flying Corps during the First World War but was revived in 1919 in the post-war RAF. The rank is used by air forces of many countries that have historical British influence.

This article is about the air force rank. For the film, see Flight Lieutenant (film).

Flight lieutenant is immediately senior to flying officer and immediately below squadron leader. It is usually equivalent to the rank of lieutenant in the navy and of the rank of captain in other services.


The equivalent rank in the former Women's Auxiliary Air Force (WAAF), Women's Royal Air Force (WRAF) and Princess Mary's Royal Air Force Nursing Service (PMRAFNS) (until 1980) was flight officer.
