Pilot officer
Pilot officer (Plt Off or P/O) is a junior officer rank used by some air forces, with origins from the Royal Air Force.[1] The rank is used by air forces of many countries that have historical British influence.
Pilot officer is the lowest ranking commissioned officer immediately below flying officer. It is usually equivalent to the rank of second lieutenant in other services.
The equivalent rank in the Women's Auxiliary Air Force (WAAF) was "assistant section officer".
