Aires' governorship was linked to the creation of the Military Academy in Angra (decreed by King John VI); the construction of the military road of Praia (linking Angra and Praia) and the battery installed in the Fort of Santo António do Monte Brasil, in addition to the transformation of Ponta Delgada into a free trade zone (a consequence of the Peninsular Wars) and which ended the construction of the trans-Atlantic port in Vila Franca). Owing to anomalies created by the Portuguese Corte's stay in Angra, the municipal council of Angra requested that Aires Pinto create a tribunal to investigate.
