On 4 April 1947, upon sufficient ratifications to the Chicago Convention, the provisional aspects of the PICAO were no longer relevant and it officially became known as ICAO. The first official ICAO Assembly was held in Montreal in May of that year.

This was the Provisional ICAO (PICAO), which began to function in August 1945. PICAO was to remain in existence until the permanent organization was created, but its life in any case was restricted to three years (Article 1 - Section 3 of the Interim Agreement).

PICAO began operating on 6 June 1945, replacing ICAN. The 26th country ratified the convention on 5 March 1947 and, consequently, PICAO was disestablished on 4 April 1947 and replaced by ICAO, which began operations the same day.

This Organization was in operation from August 1945 to April 1947 when the permanent ICAO came into being. Its seat was in Montreal, Canada and in 1947 the change from PICAO to ICAO was little more than a formality.

PICAO or Picao may refer to: Picão, a settlement in the northeastern part of Príncipe Island in São Tomé and Príncipe; David Picão (1923-2009), Brazilian bishop; Provisional International Civil Aviation Organization, which became the International Civil Aviation Organization in 1947.
