In the aftermath of the Second World War and in the framework of the reorganisation of the Belgian Army an artillery observation squadron based on the British model and called AIR OP (Air Observation Post) was created. On June 1st 1947 Major Van der Stock is tasked to go to Brasschaat to set up the 369th Squadron AOP as part of the Belgian Militair Vliegwezen/Aviation Militaire. This mission was successfully accomplished with the official establishment of the unit on July 31, 1947. On February 14, 1948 the unit acquires it's first aircraft; De Havilland DH.82 Tiger Moth T-24. The unit was equipped with two aircraft of this type, in order for pilots to retain their aerobatic qualification.

With the onset of the Cold War, it was deemed necessary to tighten the alliance between the European countries. Belgium thus committed itself to restructuring its Air Force within the framework of this new European Military organisation. So in February 1948, barely eight months after its creation, 369 Squadron was redesignated 15th Squadron Air OP (Air Observation Post) and equipped with DH.82 Tiger Moth and Auster AOP Mk VI. Only 349 Squadron and 350 Squadron retained their designation, awarded to them during the war in the RAF, because of their rich heritage.

On September 1st 1949, the eight official insignia of the squadrons of the first World War, are handed over to the new Air Force units by General Leboutte during a ceremony organised at Florennes airbase. Major Van Der Stock (CO of the 15dth Squadron Air OP at Brasschaat) receives the flag and connected traditions of N° 6 "Bee" Squadron from the hands of General Bergé.

On 16 July 1952, 15th Squadron AOP receives its first Piper L-18 Super Cubs at Brasschaat. Some 157 of these light aircraft (OL-01 tot OL-157) were delivered in the framework of the Military Defence Assistance Program (MDAP) to allow the creation of 4 observation units. American generosity made it possible to export 16 aircraft to Denmark (L-88 tot L-103), and 9 aircraft (L-104 tot L-112) to the Netherlands. Six L18C's were shipped to the Belgian Congo for the Force Publique.

On November 20, 1952, two De Havilland DHC-1 Chipmuck (C-1), were delivered to Brasschaat . They were obtained for evaluation purposes to find a new basic trainer and to replace the Tiger Moth .

In 1953, the no 16 Squadron is formed. Both units are equipped with the Auster Mk VI and the Piper L18C. On April 1st, 15 and 16 Squadron AOP were officially transferred to the newly created Light Aviation of the Belgian Army.

In 1947, the Belgian Air Force ordered 65 SV4Bs for basic training to replace the Tiger Moths. The last SV4B left the factory on October 7th. They were used in their basic training role up until their replacement by the Marchetti SF 260, in 1969.

The Light Aviation squadron at Brasschaat wore a "bee" in its insignia on top of the letter A for Albert underneath a royal crown. The "bee" originated with the 6th squadron which was formed by King Albert I. I n turn, 369 Squadron wears the "bee" in its insignia as a symbol of its tradition and the rich heritage which preceded.
