Pelletier d'Oisy began his aviation career as a World War I flying ace credited with five aerial victories.

[1] On 24 April 1924, Pelletier d'Oisy and Adjutant Lucien Besin departed Paris eastbound in a Breguet 19.A.2 in an attempt to fly around the world.

[5] Pelletier d'Oisy was in Hong Kong when a British Royal Air Force team of aviators making an eastbound attempt to circumnavigate the world arrived there on 30 June 1924, and he traded flying stories with Squadron Leader Archibald Stuart-MacLaren and Flying Officer William Plenderleith of the British team.

[7] During the interwar period, joyful and talkative Pelletier d'Oisy was a popular character in France, best known by his nickname of Pivolo (phonetical pun for Pie-vole-haut -High flies the magpie- which his comrades-in-arms had coined after his habit as a flight instructor to always end a briefing by telling greener recruits the catchphrase :"et p(u)is vole haut", stressing the importance of starting air combat with an altitude advantage.

A popular brand of Vermouth with an iconic poster and label by Art-Deco artist Adolphe Mouron Cassandre, [8] was named after him.

As of 2023 a bar-Restaurant in Toulouse (capital city of his native Gascony) still honours his name[9] Having served in both Indochina and Tunisia, d'Oisy rose to the rank of General by the end of the Second World War.
